John D. MacArthur Beach State Park
Unique Features
Overview: John D. MacArthur Beach State Park is located Palm Beach County.
The initial acquisition of John D. MacArthur Beach State Park occurred in 1981
from Palm Beach County.
The purpose of John D. MacArthur Beach State Park is to conserve and protect
valuable natural communities such as the maritime hammock. The park has
the best representation of this natural community in Palm Beach County.
Natural: The park contains three distinct natural features including: Lake
Worth Cove, Munyon Island and the Atlantic Beach. Along with dense maritime
hammocks throughout the park.
Archaeological/Historical: The cultural sites at the park represent the
history of southeast Florida, as it served as an area for cultural ceremonies
trade and commerce. There is evidence of prehistoric shell middens on the
property, along with remnants of a historical hotel that was once located on
Munyon Island, the Hygeia Hotel.
Management Goals, Objectives and Actions
Measurable objectives and actions have been identified for each of the
Division’s management goals for John D. MacArthur Beach State Park. Please
refer to the Implementation Schedule and Cost Estimates in the
Implementation Component of this plan for a consolidated spreadsheet of the
recommended actions, measures of progress, target year for completion and
estimated costs to fulfill the management goals and objectives of this park.
While the Division of Recreation and Parks utilizes the ten-year management
plan to serve as the basic statement of policy and future direction for each
park, a number of annual work plans provide more specific guidance for
Division staff to accomplish many of the resource management goals and
objectives of the park. Where such detailed planning is appropriate to the
character and scale of the park’s natural resources, annual work plans are
developed for prescribed fire management, exotic plant management and
imperiled species management. Annual or longer-term work plans are
developed for natural community restoration and hydrological restoration.
The work plans provide the Division with crucial flexibility in its efforts to
generate and implement adaptive resource management practices in the state
park system. The work plans are reviewed and updated annually. Through this
process, the Division’s resource management strategies are systematically
evaluated to determine their effectiveness. The process and the information
collected is used to refine techniques, methodologies and strategies, and
ensures that each park’s prescribed management actions are monitored and
reported as required by Chapters 253.034 and 259.037, Florida Statutes.
The goals, objectives and actions identified in this management plan will
serve as the basis for developing annual work plans for the park. Since the
John D. MacArthur Beach State Park
plan is based on conditions that exist at the time the plan is developed, the
annual work plans will provide the flexibility needed to adapt to future
conditions as they change during the ten-year management planning cycle.
As the park’s annual work plans are implemented through the ten-year cycle,
it may become necessary to adjust the management plan’s priority schedules
and cost estimates to reflect these changing conditions.

INTRODUCTION
John D. MacArthur Beach State Park is located in Palm Beach County (see Vicinity
Map). Access to the park is from State Road A1A (see Reference Map). The Vicinity
Map also reflects significant land and water resources existing near the park.
John D. MacArthur Beach State Park was initially acquired on July 7, 1981 with
funds from the Land Acquisition Trust Fund (LATF). Currently, the park comprises
436.39 acres. The Board of Trustees of the Internal Improvement Trust Fund
(Trustees) hold fee simple title to the park and on March 22, 1982, the Trustees
leased (Lease Number 3205) the property to DRP under a fifty-year lease. The
current lease will expire on March 21, 2032.
John D. MacArthur Beach State Park is designated single-use to provide public
outdoor recreation and other park-related uses. There are no legislative or
executive directives that constrain the use of this property (see Addendum 1).
Purpose and Significance of the Park
The purpose of John D. MacArthur Beach State Park is to protect a unique and
irreplaceable cross section of coastal Florida landscape for conservation and
interpretation efforts that support valuable opportunities for resource-based
recreation in one of Florida’s most populous regions.
Park Significance
•The park contains many important and invaluable natural communities
including mangrove, estuarine grass bed, worm reef, and 121 acres of
maritime hammock which combine to make the park a prominent regional
asset. The maritime hammock is one of the largest remaining examples of
this natural community in SE Florida and has been identified as an exemplary
site by the Florida Natural Areas Inventory.
•The natural communities present in the park provide significant habitat for 29
designated plant and animal species. The park’s beach serves as critical
habitat for nesting sea turtles and records more nests annually than any
other state park. Florida manatees and juvenile green sea turtles can be
observed foraging in the seagrass beds of the park’s estuary.
•Cultural resources protected at this park span many periods of Florida’s
history from pre-historic Native American shell middens to the historic
remains of the Hygeia Hotel, a popular resort from the early 1900s. The
wealthy philanthropist and the park’s namesake, John D. MacArthur, played
an integral role in the development of the surrounding region.
2
•Recreational and interpretive opportunities of significance at the park include
two miles of beach with nearshore reef and hardbottom habitat that provide
visitors with excellent opportunities for swimming, snorkeling and fishing.
The park also features a large estuarine lagoon with restricted boat access
that is outstanding for kayaks, canoes, paddleboards and birdwatching. A
nature center provides visitors with an informative overview of the resources
the park has to offer.
John D. MacArthur Beach State Park is classified as a State Park in the DRP’s unit
classification system. In the management of a State Park, a balance is sought
between the goals of maintaining and enhancing natural conditions and providing
various recreational opportunities. Natural resource management activities are
aimed at management of natural systems. Development in the park is directed
toward providing public access to and within the park, and to providing recreational
facilities, in a reasonable balance, that are both convenient and safe. Program
emphasis is on interpretation on the park's natural, aesthetic and educational
attributes.
Purpose and Scope of the Plan
This plan serves as the basic statement of policy and direction for the management
of John D. MacArthur Beach State Park as a unit of Florida's state park system. It
identifies the goals, objectives, actions and criteria or standards that guide each
aspect of park administration, and sets forth the specific measures that will be
implemented to meet management objectives and provide balanced public
utilization. The plan is intended to meet the requirements of Sections 253.034 and
259.032, Florida Statutes, Chapter 18-2, Florida Administrative Code, and is
intended to be consistent with the State Lands Management Plan. With approval,
this management plan will replace the 2005 approved plan.
The plan consists of three interrelated components: Resource Management
Component, Land Use Component and Implementation Component. The Resource
Management Component provides a detailed inventory and assessment of the
natural and cultural resources of the park. Resource management needs and issues
are identified, and measurable management objectives are established for each of
the park’s management goals and resource types. This component provides
guidance on the application of such measures as prescribed burning, exotic species
removal, imperiled species management, cultural resource management and
restoration of natural conditions.
The Land Use Component is the recreational resource allocation plan for the park.
Based on considerations such as access, population, adjacent land uses, the natural
and cultural resources of the park, and current public uses and existing
development, measurable objectives are set to achieve the desired allocation of the
3
physical space of the park. These objectives identify use areas and propose the
types of facilities and programs as well as the volume of public use to be provided.
The Implementation Component consolidates the measurable objectives and actions
for each of the park’s management goals. An implementation schedule and cost
estimates are included for each objective and action. Included in this table are (1)
measures that will be used to evaluate the DRP’s implementation progress, (2)
timeframes for completing actions and objectives and (3) estimated costs to
complete each action and objective.
All development and resource alteration proposed in this plan is subject to the
granting of appropriate permits, easements, licenses, and other required legal
instruments. Approval of the management plan does not constitute an exemption
from complying with the appropriate local, state or federal agencies. This plan is
also intended to meet the requirements for beach and shore preservation, as
defined in Chapter 161, Florida Statutes, and Chapters 62B-33, 62B-36 and 62R-
49, Florida Administrative Code.
In the development of this plan, the potential of the park to accommodate
secondary management purposes was analyzed. These secondary purposes were
considered within the context of the DRP’s statutory responsibilities and the
resource needs and values of the park. This analysis considered the park natural
and cultural resources, management needs, aesthetic values, visitation and visitor
experiences. For this park, it was determined that no secondary purposes could be
accommodated in a manner that would not interfere with the primary purpose of
resource-based outdoor recreation and conservation. Uses such as water resource
development projects, water supply projects, stormwater management projects,
linear facilities and sustainable agriculture and forestry (other than those forest
management activities specifically identified in this plan) are not consistent with
this plan.
The potential for generating revenue to enhance management was also analyzed.
Visitor fees and charges are the principal source of revenue generated by the park.
It was determined that multiple-use management activities would not be
appropriate as a means of generating revenues for land management. Instead,
techniques such as entrance fees, concessions and similar measures will be
employed on a case-by-case basis as a means of supplementing park management
funding.
DRP may provide the services and facilities outlined in this plan either with its own
funds and staff or through an outsourcing contract. Private contractors may provide
assistance with natural resource management and restoration activities or a
concessionaire may provide services to park visitors in order to enhance the visitor
experience. For example, a concessionaire could be authorized to sell merchandise
4
and food and to rent recreational equipment for use in the park. A concessionaire
may also be authorized to provide specialized services, such as interpretive tours,
or overnight accommodations when the required capital investment exceeds that
which DRP can elect to incur. Decisions regarding outsourcing, contracting with the
private sector, the use of concessionaires, etc. are made on a case-by-case basis in
accordance with the policies set forth in DRP’s Operations Manual (OM).

Management Program Overview
Management Authority and Responsibility
In accordance with Chapter 258, Florida Statutes and Chapter 62D-2, Florida
Administrative Code, the Division of Recreation and Parks (DRP) is charged with the
responsibility of developing and operating Florida's recreation and parks system.
These are administered in accordance with the following policy:
It shall be the policy of the Division of Recreation and Parks to
promote the state park system for the use, enjoyment, and benefit of
the people of Florida and visitors; to acquire typical portions of the
original domain of the state which will be accessible to all of the
people, and of such character as to emblemize the state's natural
values; conserve these natural values for all time; administer the
development, use and maintenance of these lands and render such
public service in so doing, in such a manner as to enable the people of
Florida and visitors to enjoy these values without depleting them; to
contribute materially to the development of a strong mental, moral,
and physical fiber in the people; to provide for perpetual preservation
of historic sites and memorials of statewide significance and
interpretation of their history to the people; to contribute to the tourist
appeal of Florida.
The Board of Trustees of the Internal Improvement Trust Fund (Trustees) has
granted management authority of certain sovereign submerged lands to the DRP
under Management Agreement MA 68-086 (as amended January 19, 1988). The
management area includes a 400-foot zone from the edge of mean high water
where a park boundary borders sovereign submerged lands fronting beaches, bays,
estuarine areas, rivers or streams. Where emergent wetland vegetation exists, the
zone extends waterward 400 feet beyond the vegetation. The agreement is
intended to provide additional protection to resources of the park and nearshore
areas and to provide authority to manage activities that could adversely affect
public recreational uses.
Many operating procedures are standardized system-wide and are set by internal
direction. These procedures are outlined in the OM that covers such areas as
personnel management, uniforms and personal appearance, training, signs,
communications, fiscal procedures, interpretation, concessions, public use
regulations, resource management, law enforcement, protection, safety and
maintenance.
10
Park Management Goals
The following park goals express DRP’s long-term intent in managing the state
park:
•Provide administrative support for all park functions.
•Protect water quality and quantity in the park, restore hydrology to the extent
feasible and maintain the restored condition.
•Restore and maintain the natural communities/habitats of the park.
•Maintain, improve or restore imperiled species populations and habitats in the
park.
•Remove exotic and invasive plants and animals from the park and conduct
needed maintenance-control.
•Protect, preserve and maintain the cultural resources of the park.
•Provide public access and recreational opportunities in the park.
•Develop and maintain the capital facilities and infrastructure necessary to meet
the goals and objectives of this management plan.

RESOURCE MANAGEMENT COMPONENT
Introduction
The Florida Department of Environmental Protection (DEP), Division of Recreation
and Parks (DRP) in accordance with Chapter 258, Florida Statutes, has
implemented resource management programs for preserving for all time the
representative examples of natural and cultural resources of statewide significance
under its administration. This component of the unit plan describes the natural and
cultural resources of the park and identifies the methods that will be used to
manage them. Management measures expressed in this plan are consistent with
the DRP’s overall mission in natural systems management. Cited references are
contained in Addendum 3.
The DRP’s philosophy of resource management is natural systems management.
Primary emphasis is placed on restoring and maintaining, to the degree possible,
the natural processes that shaped the structure, function and species composition
of Florida’s diverse natural communities as they occurred in the original domain.
Single species management for imperiled species is appropriate in state parks when
the maintenance, recovery or restoration of a species or population is complicated
due to constraints associated with long-term restoration efforts, unnaturally high
mortality or insufficient habitat. Single species management should be compatible
with the maintenance and restoration of natural processes and should not imperil
other native species or seriously compromise the park values.
The DRP’s management goal for cultural resources is to preserve sites and objects
that represent Florida’s cultural periods, significant historic events or persons. This
goal often entails active measures to stabilize, reconstruct or restore resources, or
to rehabilitate them for appropriate public use.
Because park units are often components of larger ecosystems, their proper
management can be affected by conditions and events that occur beyond park
boundaries. Ecosystem management is implemented through a resource
management evaluation program that assesses resource conditions, evaluates
management activities and refines management actions, and reviews local
comprehensive plans and development permit applications for park/ecosystem
impacts.
The entire park is divided into management zones that delineate areas on the
ground that are used to reference management activities (see Management Zones
Map). The shape and size of each zone may be based on natural community type,
burn zone, and the location of existing roads and natural fire breaks. It is important
to note that all burn zones are management zones; however, not all management
zones include fire-dependent natural communities. Table 1 reflects the
management zones with the acres of each zone.

RESOURCE DESCRIPTION AND ASSESSMENT
Natural Resources
Topography
John D. MacArthur Beach State Park lies within the Atlantic Coastal Ridge, a
subzone of the Atlantic Coastal Lowlands that is a physiographic formation
extending the entire length of the Florida peninsula from the Georgia/Florida line to
the Homestead area (Puri and Vernon 1964). The upland acreage of the park is
located on Singer Island, a barrier island of low topographic relief measuring 11.7
miles long and from 600 ft. to one mile wide. Elevations within the park range from
sea level along the shoreline to 20 feet along the crest of the dune ridge.
Barrier islands are dynamic systems that are constantly changing. They are narrow,
often linear deposits of sand that parallel the Florida coastline. Shaped by past
geological changes, the wind, waves and tidal action, barrier islands often occur in
long chains, separated from the mainland by estuaries and saltwater wetlands.
Here the park is separated from the mainland by the northern portion of the Lake
Worth Lagoon. Due to the nature of barrier islands, the topography of the park will
continue to be influenced and altered by natural processes such as hurricanes, wind
and ocean waves and currents. The dynamic nature of the barrier island is the
result of interactions between plant growth habits and the physical processes such
as wind-driven sand movement and salt spray deposition and wave-driven erosion,
over wash, and accretion. Dunes are established and maintained as dune
vegetation increases in surface area, which in turn causes wind to slow and sand
grains to be deposited onto the land surface (Bagnold 1941). Thus, barrier islands
are formed by the action of wind and waves on the unconsolidated sand and shell.
The upper beach and foredune areas are in a constant state of flux as sand is blown
in or out of the area and the actions of waves rearranges their makeup. The

transitional zone begins beyond the foredune and continues until a recognizable
community such as a maritime hammock is reached. Transition zone vegetation is
exposed to the same physical processes as the foredune in a lesser degree; thus,
the vegetation is patchy, and the plants are constantly re-colonizing this area. The
area beyond the transitional zone is more stable because the foredune and
transitional zones provide a buffer from wind and wave action, except in the most
severe storms.
The topography of the park is dominated by a series of dune ridges running north
to south. Although not as high, the area west of Lake Worth Cove contains an old
dune ridge, approximately 5 feet high, that extends south, divides into two fingers
around Little Lake Worth Cove and then drops to sea level (Duever et al. 1981).
Presumably, both the former large-scale erosion of the dune system and the drop in
topography near the present main access trail may have been the results of
amphibious maneuvers conducted by the military during the 1960s (Duever et al.
1981). The original name applied to this section of beach, Air Force Beach, did not
have anything to do with these maneuvers. The name came from use by West Palm
Beach Air Force Base personnel between the early 1940s and 1956 when the base
was closed.
In conjunction with the topographic relief of the property, there are also exposed
rocks from the Anastasia formation that appear at low tide along the northern and
southern ends of the beach. In addition to these geological outcrops, there are
sabellariidae worm reefs offshore. The original topographic surface of Munyon
Island was significantly enlarged by dredging operations in the 1930s and 1960s
when the island was used to store dredged material during the construction and
maintenance of the Intracoastal Waterway (ICW). The material was deposited on
and around the island’s wetlands tripling the size of the island from 15 to 45 acres.
Some of this spoil was removed during a restoration project undertaken by Palm
Beach County when surface elevations were lowered to support red mangroves. In
general, the trend of the park’s topography will be affected by general sea level
rise, northeastern winter storms and hurricanes.

Geology
Dominant geographic features along much of Florida’s coastline are its many barrier
islands. Shaped by past geological changes, wind, waves and tidal action barrier
islands often occur in long chains, separated from the mainland by estuaries and
salt-water wetlands.
The formation of Singer Island took place as part of the series of events, which
shaped Florida. This peninsula began with sediment deposition in northern Florida
from rivers draining the Appalachian Mountains and in places south of this area
from sediments of marine carbonates, shell fragments and microscopic organisms
being deposited under a shallow sea. During the Pleistocene epoch, four great ice
ages brought peninsular exposure with the glacial advances, and flooding during
each retreat. Each cycle was marked by a different thickness and composition of
sediments lay down during inundation and the subsequent consolidation during
regression. During several events in the Pleistocene, the consolidated coquinoid
limestone of the Anastasia Formation was formed as the base rock. The Pamlico
Sand, surface formation of the island, merely represents the latest of the marine
repository episodes. Thus, the sands of this area are covering the Anastasia
Formation.
This rock formation is found along the east coast of Florida from its type locality on
Anastasia Island to Broward County, where it merges with the Miami Limestone.
The lithology of this unit varies from coarse rock composed of whole coquina shells
and quartz sands, to a sandstone composed of carbonate and quartz sand particles.
The cementing agents can be calcium carbonate or iron oxide.
With the beginning of the Wisconsin Ice Age, the final Ice Age of the Pleistocene
epoch, the ice increased, and sea level steadily fell until about 20,000 years ago.
Then, the sea reached a low point close to 300 feet below the present level. At the
time, the climate was windy, cool, and dry—conducive to forming large dune
formations along the coast.
From about 15,000 to 6,000 years ago, Singer Island became more than just a
large sandbar. Sea level rose relatively rapid at more than three feet per century.
Near the end of this period, modern vegetation and climate became better
established, and the rise in sea level slowed.
In the future, rising sea levels and the continuous movement of beach sand will
perpetually change the shoreline. In addition, severe northeast storms and
hurricanes will also inflict dramatic landform changes to the barrier island.
Geologically, the island is a continuously changing landform, responding to the
effects of both anthropogenic events and natural forces.
21
Soils
For many years, biologists and soil scientists have recognized the relationship that
exists between soil types and plant distribution, and often vegetation can provide
clues regarding dominant soil types. A complete description of the seven soil types
found in John D. MacArthur Beach State Park is contained in Addendum 4. The Soils
Map illustrates the distribution of the soils throughout the park. Information for
these seven soil series was obtained from the United States Department of
Agriculture, Natural Resources Conservation Services.
The soils of the park are geologically immature because of the relatively recent
formation of the barrier island and the action of wind and rainfall on the soils. They
are primarily composed of sand, quartz, and shell fragments. The soil associations
of the park and barrier island are classified to be nearly level to gently sloping,
poorly to excessively drained, with a mixture of carbonate sand and shell
fragments.
Kesson mucky sand, tidal, is the predominant soil type found in the park consisting
of 125.1 acres or 23.5 percent of the total soil composition for the park. The park
contains 26.5 percent of the total of this soil type for all of Palm Beach County.
Formerly mapped as tidal swamp, this soil is found along the shoreline of the Lake
Worth Lagoon, the Lake Worth Cove and the mangrove areas of the park. It is
subject to tidal flooding creating a high salinity environment and is often exposed
during periods of low tide.
Canaveral-Urban land complex is the second most abundant soil type comprising
90.9 acres or 17.1 percent of the total soil composition for the park. Sand is the
dominant component of this soil and is found throughout the typical profile.
Because the freshwater lens is found close to the surface, this soil type is able to
support a more diverse plant community and is usually found in association with
the maritime hammock.
Cocoa-Urban land complex is found in association with upland coastal ridges at the
park. This soil type is similar to Canaveral and Palm Beach soils where sand is the
dominant component. This soil type is found in a small segment of maritime
hammock in the northern section of the park and a small area along the southern
boundary. The Cocoa-Urban land complex comprises 33.2 acres or 6.2 percent of
the total soil composition for the park.
Palm Beach-Urban land complex is found in the upper beaches and dunes of the
park where drainage is excessive, and the available water capacity is very low. The
Palm Beach-Urban land complex comprises 32.9 acres or 6.2 percent of the total
soil composition for the park.
Quartzipsamments, shaped, represent material dredged from the ICW and consists
of thick deposits of sand and shell materials. This soil type is located on Munyon
Island and has been altered, or shaped, from its original deposition during a
22
restoration project to improve natural habitats in the park. Quartzipsamments
comprise 21.9 acres or 4.1 percent of the total soil composition for the park.
Beaches form a narrow strip along the Atlantic shoreline that is periodically flooded
by tides and wave action. It is composed of quartz sand and calcium carbonate
particles derived from fragments of marine animals and plants. Beaches also
include some small areas of low dunes that receive less flooding and can support
salt tolerant plants. Natural vegetation is scarce and confined to the low dune areas
because of the constantly shifting sand and periodic flooding. Beaches comprise
11.9 acres or 2.2 percent of the total soil composition for the park.
Arents-Urban land complex is the smallest soil component within the park
consisting of 1.4 acres or 0.3 percent of the total soil composition. It is located on
the northern boundary and is associated with an unimproved road used by park
staff for beach access.
Conservation of soil resources in the park is achieved by following best
management practices to prevent soil erosion. Although a certain level of soil
erosion is naturally associated with barrier islands, anthropogenic influences can
seriously exacerbate the situation. On the northern and southern boundaries,
seawalls are used to protect private property. During strong storms, wind driven
waves erode the dunes and beaches in front of these walls. Although some erosion
does occur on park beaches, it is not amplified due to the lack of coastal armoring.
The DRP utilizes various methods to minimize soil erosion by minimizing visitor
impacts to the natural resources and planting native vegetation. For example, dune
erosion resulting from human foot traffic was minimized by a series of three dune
crossovers. In areas of excessive soil erosion where off-trail usage has occurred,
rails or barriers are constructed to prevent visitors from leaving designated trails.
In addition, native vegetation has been planted to stabilize soils in eroded areas
along the beach and encourage dune formation.

Minerals
There are no known mineral deposits of commercial value located within John D.
MacArthur Beach State Park.
Hydrology
The hydrological resources of John D. MacArthur Beach State Park are divided into
two broad categories: surface and ground water. All surface waters within the park
are classified as Outstanding Florida Waters in accordance with Chapter 27, Section
403.061 of the Florida Statutes and 62-302.700, Florida Administrative Code. This
designation is intended to protect and maintain existing acceptable water quality
standards of the park’s hydrological systems and prevent further degradation of the
water quality of that system. The park’s hydrological surface features include the
near shore waters of the Atlantic Ocean, the northern section of the Lake Worth
Lagoon where the Intracoastal Waterway (ICW) is located, Lake Worth Cove, Little
Lake Worth Cove and all associated mangrove wetlands. The ground water
resources include the Floridan Aquifer and the Surficial Aquifer. Since the park’s
largest hydrological features: the Atlantic Ocean, the Lake Worth Lagoon, and both
aquifers extend far beyond the boundaries of the park, management of these
systems is complex.
Surface water in the park is mostly influenced by the Atlantic Ocean and the Lake
Worth Lagoon. Drainage in the park is westward into the Lake Worth Cove and
Little Lake Worth Cove. The mean range of the semi-diurnal tide along the beach is
about 3 feet, 9 inches (Van de Kreeke and Wang 1978). Because of the low
topography of the barrier island, flooding can be a problem that affects the park. A
combination of high spring tides and strong easterly winds can “stack up” water
along the seashore and the Intracoastal Waterway resulting in localized flooding.
In general, there is good tidal exchange surrounding the park, but both Lake Worth
Cove and Little Lake Worth Cove have reduced tidal exchange because of restricted
flow at Burnt Bridge on A-1-A regarding the former, and through culverts at the
latter.
Originally, the Lake Worth Lagoon was an isolated freshwater lagoon. Beginning in
the late 19th century, canals were dredged to connect the coastal lagoons and
create the ICW for navigational purposes. Over time, inlets were dredged to
improve water circulation in the canal/estuary system and provide access to the
Atlantic Ocean. These alterations permanently changed the natural dynamics of
Lake Worth Lagoon resulting in the biodiversity found today.
This park does not use the Floridan aquifer because of the depth of the water table
and the high level of dissolved solids. Presently, the park and other nearby
residents use potable water from utilities that have well fields on the mainland that
draw from the surficial aquifer. Increasing demand for water from the surficial
aquifer system in the highly populated coastal area of Palm Beach County, Fla., has
prompted a need to find supplemental sources of available water for both public
26
and agricultural use. The virtually untapped Floridan aquifer system can be used to
assist in this need. Because of the brackish nature of this groundwater resource,
two alternative methods of use are currently expanding: the reverse-osmosis
method, and the aquifer storage and recovery (ASR) method.
Within the park, the surficial aquifer is present near the land surface and functions
as a freshwater lens. Freshwater being less dense than saltwater is suspended on
top of the saltwater forming a lens that plants utilize. The survival of barrier island
vegetation other than halophytic species is entirely dependent on precipitation and
the re-charging of the freshwater lens. Most of the recharge to the surficial aquifer
is supplied by rainfall that percolates downward into the aquifer and then moves
laterally through the system until it discharges to a surface-water body or to the
ocean. Rainfall is abundant in the southeastern portion of the state during the wet
season (May to September). During this period, precipitation occurs almost daily
due to convective heat and differences between the land and sea. However, the
park receives slightly less rainfall than the inland Palm Beach County because of the
prevailing southeast winds that carry the rain clouds further inland during the rainy
season. Much of the rainfall in the park infiltrates into the shallow unconfined
aquifer, yet a large amount runs off or remains at the surface where it is returned
to the atmosphere by evapotranspiration. The runoff flows into mangrove wetlands,
coves and lagoons within the park.
Natural Communities
This section of the management plan describes and assesses each of the natural
communities found in the state park. It also describes of the desired future
condition (DFC) of each natural community and identifies the actions that will be
required to bring the community to its desired future condition. Specific
management objectives and actions for natural community management, exotic
species management, imperiled species management [and population restoration]
are discussed in the Resource Management Program section of this component.
The system of classifying natural communities employed in this plan was developed
by the Florida Natural Areas Inventory (FNAI). The premise of this system is that
physical factors such as climate, geology, soil, hydrology and fire frequency
generally determine the species composition of an area, and that areas that are
similar with respect to those factors will tend to have natural communities with
similar species compositions. Obvious differences in species composition can occur,
however, despite similar physical conditions. In other instances, physical factors are
substantially different, yet the species compositions are quite similar. For example,
coastal strand and scrub--two communities with similar species compositions--
generally have quite different climatic environments, and these necessitate different
management programs. Some physical influences, such as fire frequency, may vary
from FNAI’s descriptions for certain natural communities in this plan.
When a natural community within a park reaches the desired future condition, it is
considered to be in a “maintenance condition.” Required actions for sustaining a
community’s maintenance condition may include; maintaining optimal fire return
27
intervals for fire dependant communities, ongoing control of non-native plant and
animal species, maintaining natural hydrological functions (including historic water
flows and water quality), preserving a community’s biodiversity and vegetative
structure, protecting viable populations of plant and animal species (including those
that are imperiled or endemic), and preserving intact ecotones that link natural
communities across the landscape.
The park contains five distinct natural communities as well as altered landcover
types (see Natural Communities Map). A list of known plants and animals occurring
in the park is contained in Addendum 5.
28
BEACH DUNE - 18.61 acres
Desired Future Condition: Beach dune is a coastal mound or ridge of unconsolidated
sediments found along shorelines with high energy waves. Vegetation will consist of
herbaceous dune forming grass species such as sea oats (Uniola paniculata) and
sand cordgrass (Spartina alterniflora). Other typical species may include sea rocket
(Cakile spp.), railroad vine (Ipomea pes-caprae), seashore paspalum (Paspalum
vaginatum), beach morning glory (Ipomea imperati), and beach sunflower
(Helianthus debilis) along the Atlantic coast. Occasionally shrubs such as seagrape
(Coccoloba uvifera) may be scattered within the herbaceous vegetation.
Description and assessment: The beach dune community is in good (northern) to
excellent (southern) condition and is the only natural community found in
management zone MB-07 (Management Zones Map). This community is narrower,
steeper at the north end of the park, wider, and flatter at the southern end. The
tall, extensive dunes represent one of the best examples of this community in south
Florida. The dunes range from a few feet above sea level to 20 feet tall. The best
examples of these tall dunes can be seen north of the main crossover. In 2012,
Tropical Storm Sandy had eroded some of the larger dunes immediately south of
the park’s north boundary. The southern portion of the beach dune community is
colonized by scattered populations of sea oats, beach spurge (Chamaesyce sp.) and
railroad vine. The beach dune community is continuously decolonized by plants,
since storm waves or high tides disturb it periodically. Beyond the limit of yearly
wave action, wind-blown sand can accumulate around plants as they grow upward
to form the foredune. Since a supply of loose sand is always present, sand burial is
a constant factor on the foredune, its rate dependent on the force and direction of
the winds and the mobility of the sand grains (Meyers and Ewel 1990).
Past hurricanes and strong winter storms have caused noticeable erosion along the
park’s northern beach. This section of the beach dune community becomes
narrower and is slower to recover from these storm events than the southern
beach. There are several reasons for the differences in the beach width, but the
most obvious is the lack of any foredune system on the northern stretch of beach.
Along the southern beach, vegetation has established itself and foredunes are
forming around these pioneer plants. Foredunes are usually built by grasses whose
upward growth keeps pace with sand burial and whose lateral growth helps build a
continuous dune ridge (Meyers and Ewel 1990).
The beach community serves as an important nesting habitat for imperiled sea
turtles. Florida beaches are one of the three major nesting areas in the world for
loggerhead turtles (Caretta caretta). Other imperiled sea turtles that use the park
for nesting are the leatherback turtles (Dermochelys coriacea) and green turtles
(Chelonia mydas).
General management measures: The principle threat to the beach dune community
that includes the park’s sandy beaches is erosion caused by natural storm events.
Periodic large-scale beach nourishment projects are regularly used in other areas to
counteract the effects of erosion. However, with potential impacts to the submerged

resources of the park and the temporary loss of nesting habitat for imperiled sea
turtles, careful planning and deliberation must be applied before using this
alternative approach. Please refer to the Coastal/Beach Management section for
more discussion concerning erosion and beach nourishment issues.
The park will continue to implement management activities to minimize erosion
such as the planting of native dune building vegetation, removal of exotic
vegetation and establishing designated access trails as needed.
The park will continue to participate in statewide monitoring programs for nesting
sea turtles and assist in the recovery efforts for these imperiled species. These
programs and efforts are discussed in the Resource Management Program section.
MARITIME HAMMOCK – 137.46 acres
Desired Future Condition: Maritime hammock is a coastal evergreen hardwood
forest occurring in narrow bands along stabilized coastal dunes. Canopy species will
typically consist of live oak (Quercus virginiana), red bay (Persea borbonia), and
cabbage palm (Sabal palmetto). The canopy will typically be dense and often salt-
spray pruned. Understory species may consist of yaupon holly (Ilex vomitoria), saw
palmetto (Serenoa repens), and/or wax myrtle (Myrica cerifera). Herbaceous
groundcover will be very sparse or absent. Variation in species composition exists
along the coast - heading southward, tropical species become more prevalent.
Description and assessment: The tropical maritime hammock at John D. MacArthur
Beach State Park represents one of the best examples of this community in Palm
Beach County. The hammock has a diverse assemblage of tropical trees and
understory making it an ideal stop over for many migratory bird species. The
maritime hammock is in excellent condition and is found in management zones MB-
04, MB-05, MB-06 and MB-09. The maritime hammock includes a thin, intermittent
strip of vegetation behind the beach dune and a mature hammock between A-1-A
and Lake Worth Cove. The main portion of the hammock includes many large
tropical trees like mastic (Sideroxylon foetidissimum) and some temperate species
like live oak. There are also some large satin leaf (Chrysophyllum oliviforme) trees,
a small fresh water depression with pond apple (Annona glabra) and a few
scattered remnant slash pines (Pinus elliottii). The hammock contains several
species of exotic invasive plants, with Brazilian pepper being the most significant
threat. Through a joint restoration project on Munyon Island, an area of restored
maritime hammock was established. Much of the native vegetation had survived
the harsh conditions and have grown into a functioning hammock community.
However, several species of exotic plants: Jacob's ladder (Pedilanthus tithymaloides
var smallii) and bowstring hemp (Sansevieria hyacinthoides), have established
sizeable populations.
General management measures: Invasive exotics located in the hammock areas
that are accessible by foot are in a maintenance stage. Many of the larger, seed
bearing plants have been removed. Park staff will continue to monitor and treat the
remaining small patches of herbaceous exotic vegetation where possible. Access to
32
some areas is limited. As Munyon Island is only accessible by boat, removing exotic
vegetation from the island requires more planning and effort. The long-term
maintenance of previous exotic removal projects will require periodic treatment to
remove any new seedlings or saplings present. The park has a productive
greenhouse staffed by volunteers. Many of the native species of plants raised in the
greenhouse are used throughout the park on restoration projects.
MANGROVE SWAMP- 144.04 acres
Desired Future Condition: Mangrove swamp is typically characterized as a dense
forest occurring along relatively flat, low wave energy, marine and estuarine
shorelines. The dominant overstory will include red mangrove (Rhizophora mangle),
black mangrove (Avicennia germinans), white mangrove (Laguncularia racemosa),
and buttonwood (Conocarpus erectus). These four species may occur either in
mixed stands or often in differentiated, monospecific zones based on varying
degrees of tidal influence, levels of salinity, and types of substrate. Red mangroves
will typically dominate the deepest water, followed by black mangrove in the
intermediate zone, and white mangroves and buttonwood in the highest, least
tidally influenced zone. Mangroves will typically occur in dense stands (with little to
no understory) but may be sparse, particularly in the upper tidal reaches where salt
marsh species predominate. When present, shrub species can include seaside oxeye
(Borrichia arborescens, B. frutescens), and vines including gray nicker (Caesalpinia
bonduc), coinvine (Dalbergia ecastaphyllum), rubbervine (Rhabdadenia biflora),
and herbaceous species such as saltwort (Batis maritime), shoregrass
(Monanthocloe littoralis), perennial glasswort (Sarcocornia perennis), and giant
leather fern (Acrostichum danaeifolium). Soils will generally be anaerobic and are
saturated with brackish water at all times, becoming inundated at high tides.
Mangrove swamps will occur on a wide variety of soils, ranging from sands and
mud to solid limestone rock. Soils in South Florida are primarily calcareous marl
muds or calcareous sands and along Central Florida coastlines, siliceous sands. In
older mangrove swamps containing red mangroves, a layer of peat may build up
over the soil from decaying plant material (primarily red and black mangrove
roots).
Description and assessment: The mangrove swamp community represents the
largest of the floral-based communities at John D. MacArthur Beach State Park. It is
in excellent condition and represents one of the largest remnants of undeveloped,
mangrove shorelines remaining in the Lake Worth Lagoon. Over 55% of
Lake Worth Lagoon’s mangrove habitats are within the park boundaries. This is an
assemblage of the three species of mangroves (red, black and white) along with a
full complement of halophytic herbs and shrubs. This community is found along the
relatively low energy intertidal and supratidal shorelines of the Lake Worth Lagoon,
the Lake Worth Cove, and Little Lake Worth Cove located in management zones
MB-01, MB-02, MB-03, MB-04, MB-05, MB-06, MB-08 and MB-09.
Unlike most vascular plants, mangroves have managed to adapt to a harsh
environment characterized by sustainable, anaerobic sediments, fluctuating water
levels and waters with high concentrations of salt. They have accomplished this
33
through evolutionary adaptations of their root systems, morphological and
physiological mechanisms for maintaining salt balance, and reproductive dispersal
strategies (Meyers and Ewel 1990). The oxygen-poor soil limits root growth to
within a few feet of the surface. Mangroves do not have a deep taproot to anchor
them during storm events, but they produce extensive, interlaced, horizontal roots
that keep them anchored and help to minimize erosion. Some species, such as the
red mangrove, have developed prop roots that extend into the soil bracing the tree
during storm events.
Mangroves play an important role in the marine and estuarine ecosystems of the
park. They are the primary producers establishing the microbial food web that
sustains a wide variety of species. Over 220 fish species have been recorded
utilizing the mangrove swamp community at some point during their lifecycle.
Important commercial and recreational marine species find food and shelter in the
mangrove swamp. The shallow waters, entanglement of roots, and abundant food
make this an ideal nursery for fish and invertebrate species such as the spiny
lobster (Panularis argus), snook (Centropomus undecimalis), and mangrove
snapper (Lutjanus apodus). A wide variety of birds, including the endangered wood
stork (Mycteria Americana), the double-crested cormorant (Phalacrocorax auritus),
and the brown pelican (Pelicanus occidentalis), use mangroves for nesting,
roosting, and protection from predators and the elements. Sessile invertebrates,
such as oysters and barnacles, use the network of roots and tree trunks as points of
attachment whenever these surfaces are void of macroalgae. Together with the
macroaglae, these invertebrates have been documented to filter large volumes of
water thereby maintaining water quality within the mangrove community. During
periods of tropical storms and hurricanes, mangroves have been shown to baffle
storm and wave energy and create an extensive root system that helps to stabilize
the shoreline.
Because of the health of this natural community and the scarcity of mangroves in
the Lake Worth Lagoon, these mangroves function as a seed source for this section
of the lagoon. Palm Beach County biologists have also collected seeds from the
park’s red mangroves to be grown into saplings that are used for restoration
projects in the southern portion of the Lake Worth Lagoon. DRP biologists are
careful to permit a limited number of seeds to be removed from the park so that
recruitment of saplings within the park boundaries is not disrupted.
General management measures: The major threat to this community is erosion
from the high volume of vessel traffic in the ICW. This area of the ICW does not
have designated speed zones to help moderate vessel speed. Instead the shallow
grass beds and sand bars reduce wave action from vessel wakes. DRP will continue
to work with and support efforts by the FFWCC to regulate vessel speed in the Lake
Worth Lagoon.
Another potential impact is the degradation of the water quality by point and non-
point pollution sources. Storm water runoff from the urbanized areas surrounding
the park and the freshwater discharge from drainage canals entering the Lake
Worth Lagoon have the potential to adversely impact water quality. Large volumes
34
of surface water high in nutrients such as nitrogen and phosphorous flowing into
the estuarine system of the park could alter this system by causing eutrophication
and a change in species composition.
The park will also continue to utilize and enforce state and federal regulations and
designations to protect these valuable natural resources. Mangroves are designated
as essential fish habitat and habitat areas of particular concern (HAPC) by the
South Atlantic Fishery Management Council. HAPCs are rare, particularly susceptible
to human-induced degradation, ecologically important, and most often found in an
environmentally stressed area.
MARINE UNCONSOLIDATED SUBSTRATE- 11.51 acres
Desired Future Condition: Marine unconsolidated substrate will consist of expansive
unvegetated, open areas of mineral based substrate composed of shell, coral gal,
marl, mud, and/or sand (sand beaches). The presence of natural marine debris, or
wrack, is considered desirable as it greatly enhances nutrient cycling and the food
web. Desired conditions include preventing soil compaction, dredging activities, and
disturbances such as the accumulation of pollutants.
Description and assessment: The marine unconsolidated substrate is in excellent
condition and is located entirely in management zone MB-07. This is a highly
variable community covering several different habitats along the high-energy beach
from the supratidal zone to the intertidal zone. Sediment is also variable from
course sand and shell to fine mud. Species composition usually includes those
organisms especially adapted for a highly variable community with burrowing
abilities or attachment capabilities. In the supratidal zone, such species include
common mole crab (Emerita talpoida) and variable coquina clam (Donax variabilis).
Infaunal organisms found here help to support migrating and resident shorebirds.
General management measures: The marine unconsolidated substrate is in the
desired future condition. Natural erosion from storms and wave action are to be
expected, but the natural process of sand transport and deposition tends to replace
the sand on the beach and minimizes any impacts to this community.
ESTUARINE SEAGRASS BED – 15.79 acres
Desired Future Condition: Estuarine seagrass beds are typically characterized as
expansive stands of vascular plants and are one of the most productive
communities in the world. Seagrass beds will occur in clear, coastal waters where
wave energy is moderate. The three most common species of seagrasses in Florida
are turtle grass, (Thalassia testudinum), manatee grass, (Syringodium filiforme),
and shoal weed (Halodule wrightii). Other seagrasses of the genus Halophila may
also occur but will be considerably less common. Seagrass beds require
unconsolidated substrate in order to establish their underground biomass root
structure. They will typically be found in waters ranging from 20° to 30°C (68° to
86°F) and require clear water for photosynthesis. Seagrass beds will not thrive
35
where nutrient levels are high because of increased turbidity and competition of
undesirable algal species.
Description and assessment: Estuarine seagrass beds are located within Lake Worth
Cove, Little Lake Worth Cove and along the eastern shore of Lake Worth Lagoon.
Like mangroves, they are a “new” community that appeared after the historical
salinity changes of Lake Worth. The seagrass beds can be found in management
zones MB-01, MB-03, MB-04 and MB-08.
An ongoing seagrass monitoring program was established in 2010 in partnership
with a variety of stakeholders including faculty and undergraduate research
assistants from Palm Beach Atlantic University, park staff, scientists and volunteers.
All seven of Florida’s seagrass species were found in the Cove, including the
federally threatened species Halophila johnsonii (Johnson’s seagrass) as well as
Ruppia maritima (widgeongrass), a species which has never been documented
within the Cove and rarely documented within the lagoon remote from freshwater
sources. (Chesnes, et al, 2011). Lake Worth Cove has the highest seagrass
diversity of any area in Lake Worth Lagoon and, along with the Indian River
Lagoon, has the greatest seagrass diversity of any estuary in the Western
Hemisphere (Chesnes, et al, 2011).
Seagrasses are the only flowering vascular plant that lives in the marine
environment. Together with a vast assemblage of macroalgae, the seagrass beds at
the park are a highly productive benthic community providing food and shelter for a
variety of economically important recreational and commercial vertebrate and
invertebrate species. In addition, Seagrasses serve as a filter for nutrients thus
improving water quality and helps to baffle wave energy, reducing erosion and
turbidity. Seagrass also acts as a substrate for epiphytic algae and sessile
invertebrates while functioning as a base for detrital food webs.
Several imperiled species utilize the estuarine seagrass beds at the park. In 1998,
Johnson’s seagrass became the first and only seagrass listed as threatened under
the Endangered Species Act. Juvenile green turtles are often observed feeding on
submerged aquatic vegetation within Lake Worth Lagoon. The Florida manatee
(Trichechus manatus latirostris), a subspecies of the West Indian manatee
(Trichechus manatus), is often observed foraging and cavorting in the shallow
seagrass beds.
The park’s seagrass monitoring program has identified a significant decline in the
abundance and distribution seagrass. Biannual surveys are conducted in Lake
Worth Cove. Since 2014, there has been a decrease in the coverage of seagrass
within the Cove. This is disturbing since the park once had some of the largest
contiguous seagrass beds in Lake Worth Lagoon. What is occurring at the park is
indicative of the seagrass community throughout Lake Worth Lagoon. Seagrasses
are an important indicator of the environmental health of a water body. According
to the Palm Beach County Lake Worth Lagoon Monitoring Project Final Report, (DEP
Agreement no. WAP028, PBC no. R2001-0401) revised, November 2003, “untreated
stormwater and other non-point source discharges are now considered one of the
36
greatest threats to the health of surface waters and, thus, to seagrasses.
Stormwater enters the lagoon through three major drainage canals and hundreds of
stormwater outfalls which discharge directly to the lagoon. The sediments contained
in stormwater damage seagrass by the formation of a muck layer which, in some
areas, may be thick enough to physically prevent the establishment of seagrasses.
In addition, wind, wave action and boat wakes re-suspend the top of the muck
layer, clouding the water column which reduces light penetration, reduces the
depth of the photic zone, and hence, affects the health and distribution of
seagrasses.”
Another area of the park experiencing a decrease in the coverage of seagrass is the
western side of Munyon Island. In May 2011, a floating dock was built on the
island. The installation of this docking facility has caused both direct and indirect
impacts to the nearshore benthic communities as well as Munyon Island itself.
Concerns of this dock being constructed along a heavily travelled section of the
Intracoastal Waterway prompted designs that would dissipate wave attenuation
thereby making the floating docks safer and more accessible. The final design
required placing boulders underneath the dock in prefabricated cribs along its entire
length. Although this design accomplished its goal of disrupting the wakes from
passing boats, the entire structure now exhibits characteristics of a groin. There is
minimal flushing and the water is calm behind the dock. This has resulted in an
accumulation of a thick sediment composed mostly of silt and mud. This
unconsolidated substrate appears to prevent the growth of seagrass.
General management measures: John D. MacArthur Beach State Park has managed
Lake Worth Cove as a ‘Motor Exclusion Zone’ since the park was acquired. Recently,
the ‘Motor Exclusion Zone’ designation was expanded to include additional
submerged grass beds located immediately south and adjacent to the Cove. This
management strategy effectively reduces the threat of future impacts to these
grass beds from boat groundings.
The seagrass monitoring program will continue and may be expanded to include
areas that are outside of current park boundaries but lie within the optimal
boundary of the park. DRP staff will continue to assist biologists with the Palm
Beach County Environmental Resource Management (ERM) Division during the
county’s seagrass surveys of Lake Worth Lagoon.
The park will continue to be an active partner in supporting Palm Beach County’s
efforts to improve water quality within Lake Worth Lagoon by reducing freshwater
discharge and sediment deposition.
The DRP will examine alternative designs for the docking facility at Munyon Island
that will enhance the seagrass community, prevent further erosion of the island and
provide public safety.
37
DEVELOPED – 9.89 acres
Desired Future Condition: The developed areas within the park will be managed to
minimize the effect of the developed areas on adjacent natural areas. Priority
invasive plant species (FLEPPC Category I and II species) will be removed from all
developed areas. Other management measures include proper stormwater
management and development guidelines that are compatible with prescribed fire
management in adjacent natural areas.
Description and assessment: Developed areas are found in the following
management zones: MB-01, MB-02, MB-04, MB-05, MB-06, MB-08 and MB-09.
These areas include residences, a workshop, administrative offices, visitors’ parking
area, education center, the boardwalk across Lake Worth Cove, two bathhouses,
three dune crossovers, pavilions and a floating boat dock on Munyon Island. An
aggressive exotic removal program has helped to minimize the spread of invasive
exotics. Also, staff are encouraged to plant only native vegetation around buildings
and residences for decorative purposes.
General management measures: Control of FLEPPC Category I and II species in this
area remains a priority to prevent their spread into the natural communities of the
park.
The raised boardwalk and associated pavilions on Munyon Island are being
threatened by erosion that was exacerbated by the installation of a docking facility
on the island. The DRP will examine alternative designs for the docking facility at
Munyon Island that will prevent further erosion of the island and provide public
safety.
Imperiled Species
Imperiled species are those that are (1) tracked by FNAI as critically imperiled (G1,
S1) or imperiled (G2, S2); or (2) listed by the U.S. Fish and Wildlife Service
(USFWS), Florida Fish and Wildlife Conservation Commission (FWC) or the Florida
Department of Agriculture and Consumer Services (FDACS) as endangered,
threatened or of special concern.
John D. MacArthur Beach State Park is an active participant in the statewide marine
turtle-monitoring program. The park provides critical nesting habitat for three
species of sea turtles: loggerhead (Caretta caretta), green (Chelonia mydas), and
leatherback (Dermochelys coriacea). In addition, the park serves as a state index
and survey beach for nesting sea turtles. During the nesting season, park staff
conducts daily surveys of the beach recording the previous night’s activities
including number of crawls, false crawls, species identification and number of nests.
The data collected from the park, in addition to data gathered from around the
state, is used by government agencies to formulate policies on nesting sea turtles.
The park utilizes a combination of management strategies that are essential for the
recovery of marine turtles. They include the continued support of the marine turtle
38
monitoring program, educational programs on the importance of marine turtles and
protection measures such as nesting surveys, light management, and predation
control.
The park is permitted under FWC guidelines to offer turtle walks to its visitors. This
interpretive program educates the public on the biology, ecology and threats
confronting marine turtles. Following a comprehensive classroom presentation, the
group is taken to the beach where many people will observe for the first time a
female turtle laying her eggs.
The population of nesting marine turtles is stable but tends to follow statewide
trends. For example, if the population of nesting loggerhead turtles is in decline
around the state, this trend is also reflected in the regional population nesting at
the park. The major threats to nesting sea turtles, their nests and turtle hatchlings
include predation from natural and introduced animals, disorientation from artificial
lighting, habitat loss and impediments to nesting from structures and escarpments.
John D. MacArthur Beach State Park is bordered by affluent residences, many of
which use coastal armament as a means of shoreline protection. Seawalls often
result in a false crawl where the female turtle cannot access prime nesting beach
and she returns to the ocean without nesting. Another consequence of seawalls
results in the female turtle nesting low on the beach in an area prone to flooding.
This wash over is harmful to the eggs and usually results in a high mortality rate.
The large metropolitan areas of Palm Beach County produce enough artificial
lighting to illuminate the western night sky beyond the park. Under these
conditions, disorientation of hatchlings would seem to be significantly high.
However at the park, disorientation seldom occurs. The tall dunes and associated
trees may help diffuse the light. Analysis of the 2013 nesting data seems to confirm
these field observations. The report shows that the northern beach which is narrow
but has the tallest dunes attracts significantly more loggerhead and green turtles
than the southern beach which is broader but has shorter dunes. In fact there is
about 3 times as many nests on the north end compared to the south end. The
number and frequency of nests decreases where the dune drops lower and the
beach gets wider. The 1.8 miles of park beaches receive in excess of 1,500 nests
per year; so lighting does not seem to be an issue with female turtles or their
young.
The predominant threat to marine turtles and their nests at the Park is predation.
Coyotes (Canis latrans) and raccoons (Procyon lotor) destroy more marine turtle
eggs in the park than any other predator. However, a host of predators benefit
from the nesting season including ghost crabs (Ocypode quadrata), American crows
(Corvus brachyrhynchos) and spotted skunks (Spilogale putorius). Even snakes
such as the Eastern coachwhip (Masticophis flagellum) have been observed
removing hatchlings from a nest.
Park staff has located and monitors known gopher tortoise (Gopherus polyphemus)
burrow sites. No additional protection measures are required at the time of this
writing.
39
The Florida Manatee (Trichechus manatus latirostris) inhabits the waters of Palm
Beach County year-round. The park supports the continued designation of manatee
protection zones in the ICW and surrounding waters and the posting of manatee
warning signs informing boaters that this species may be present. There are the
two State established Manatee Protection Zones that make up the waters of
JDMBSP. These zones are defined in Chapter 68C-22.009, Florida Administrative
Code. The park is frequently used by FWC and other agencies as an area for
rehabilitated manatees to be released back into the wild. Whenever this species is
observed by park visitors at John D. MacArthur Beach State Park, staff members
provide immediate interpretation.
Many of the listed wading birds such as herons, egrets, roseate spoonbills and
woodstorks (Mycteria americana) utilize the seagrass beds, sand flats, and
mangroves for foraging areas. Although some of the imperiled bird species are not
residents of the park, they have been observed using the natural resources of the
park. The tropical maritime hammock serves as an important stop over during
migration for neotropical migrants such as the worm-eating warbler (Helmitheros
vermivorus) and the American redstart (Setophaga ruticilla). Piping plovers
(Charadrius melodus) are a winter resident that have been observed foraging and
roosting along the beach and grass flats within the park.
Least terns (Sterna antillarum) and black skimmers (Rynchops niger) forage in
marine and estuarine waters surrounding the park. Least terns also loaf on the
sandy spit of Munyon Island. Signage and other public information are used to
advise park visitors of the need to prevent undue disturbances of loafing terns.
Annual bird census are conducted by DRP biologists and non-governmental
organizations, such as Audubon, that help document species and size of
populations. In addition, the park will continue to implement a systems
management approach that involves managing the resources as a complete
ecosystem. This strategy will provide for the resources needed to assist in the
recovery and stabilization of the imperiled bird species that use the park.
The DRP will seek a balanced approach to minimize visitor impacts to shorebirds
and the park’s sensitive coastal habitats, while managing resource-based
recreational activities. In collaboration with FWC, other government agencies, local
non-governmental organizations, and volunteers, DRP staff will identify and
delineate habitats and educate the public about shorebird protection.
Management decisions will be informed by analysis of data on habitat use in the
park during prior nesting seasons. This analysis will suggest areas of importance
where focused management actions are needed. These actions will typically
include:
•Demarcating potential shorebird habitat by enclosing the perimeter of the
habitat and buffer area with appropriate fencing and signage.
•Encouraging and focusing visitor activities into areas less suitable for
shorebird nesting habitat.
40
•Monitoring during the nesting season to identify and protect new breeding
sites.
•Providing interpretive and educational outreach to the public prior to and
during the nesting season to encourage visitor use that protects shorebirds
and their habitat.
•When the same breeding sites are used year after year, posting the
protected area will occur prior to the season (pre-posting).
•When new breeding sites are indicated, appropriate measures will be
implemented, including demarcating new protected areas and expanding or
initiating interpretive programs.
•Coordinating with FWC and local law enforcement agencies to ensure
compliance with park rules and shorebird protection, as needed.
When it is necessary to limit recreational activities or visitor access to protect
nesting habitat, DRP staff or volunteers will provide onsite interpretation to educate
visitors about the management of imperiled shorebird habitat and identify suitable
recreational areas. These outreach programs will commence prior to nesting
seasons and prior to placing limits on access to recreational areas. Pre-posting the
identified habitat areas combined with early public notification regarding the park’s
shorebird protection program will improve visitor compliance with park rules and
promote broad-based public stewardship of shorebird nesting, resting, and foraging
habitats in the park.
There are six imperiled plants found at John D. MacArthur Beach State Park. Two of
the plants are being monitored through designed programs while the other four will
be monitored using a more passive observation documentation approach in which
the presence of the plant will be documented through casual/passive observation
during routine park activities.
The royal palm (Roystonea regia) is one of the largest native palms in Florida
reaching heights up to 100 feet with a trunk diameter of 20 inches. Historically, the
species was once thought to range as far north as Volusia County, but it is now
restricted to south Florida. There are only a small number of individuals at the park
growing in the maritime hammock. Currently, there are no threats to this species at
the park and the population appears to be stable. Although a comprehensive
monitoring program is not scheduled for this species, park staff will continue to
monitor the royal palm through passive observation and documentation.
The golden leather fern (Acrostichum aureum) is a large herbaceous fern that is
fast growing and very robust. This species is found in the intermediate estuarine
zone in the high intertidal region. At the park, the golden leather fern is restricted
to the mangrove systems, however, it can grow in other areas such as fresh water
environments and salt marshes. This is a species that is opportunistic and colonizes
disturbed areas. Currently, there are no threats to this species at the park and the
population appears to be stable. Although a comprehensive monitoring program is
not scheduled for this species, park staff will continue to monitor the golden leather
fern through passive observation and documentation.
41
In 2011 and 2014, park staff conducted a project to locate and record the existing
sea lavender (Argusia gnaphalodes). Sea lavender is native to Southeast Florida
and functions as a shoreline erosion control plant. It helps to trap sand and stabilize
the dunes on which other plants can become established. Eleven specimens of sea
lavender were recorded in 2011; six specimens were recorded in 2014. The
difference in recorded specimens is a direct result of Tropical Storm Sandy which
caused extensive shoreline erosion. This data will serve as a baseline for a
monitoring project to determine the growth and health of this imperiled plant.
Johnson’s seagrass (Halophila johnsonii) is found in shallow waters that experience
minimal disturbance from visitors or vessel traffic. Of the seven species of
seagrasses found in Florida, Johnson’s seagrass is the only federally threatened
species and the only seagrass known to reproduce asexually. Johnson's seagrass
plays a major role in the health of benthic resources as a shelter and nursery
habitat. It has been documented as a food source for endangered manatees and
endangered green sea turtles. Johnson's seagrass is the rarest species of its genus.
It has a limited distribution, limited ability to disperse and colonize habitats because
of its asexual reproduction and is dependent on substrate stability. Johnson's
seagrass is the least abundant seagrass within its range. It has a disjunct and
patchy distribution along the east coast of Florida from central Biscayne Bay to
Sebastian Inlet. The largest patches have been documented inside the Lake Worth
Inlet. Threats to this imperiled plant include degraded water quality, pollution,
storm action and sedimentation, and dredging. It has been documented in the
estuarine seagrass bed in Lake Worth Cove and the shallow waters of Lake Worth
Lagoon. DRP staff will continue to conduct seagrass surveys within the Cove as part
of the seagrass monitoring program at the park.
There are no known seed banks; and although experiments have shown that
vegetative fragments survive when transplanted into the field, there is only
circumstantial evidence for unassisted recruitment by naturally produced
fragments. Thus, the plant has a reduced capacity to repopulate an area if lost due
to human or environmental perturbations. The apparent lack of sexual reproduction
suggests this species may have limited genetic diversity. Because of its small size
and minimal stored reserves, local populations may decline during periods of
unfavorable conditions, be out-competed by larger seagrasses, or become
overgrown by macroalgae. Halophila johnsonii is particularly vulnerable to sediment
disturbances, trampling, and prop scarring due to its fragile nature and
predominantly shallow growth habit; and, for these reasons, it will have a limited
recovery potential (NOAA, 2002, Final Recovery Plan for Johnson’s Seagrass
(Halophila johnsonii Eiseman).
Table 2 contains a list of all known imperiled species within the park and identifies
their status as defined by various entities. It also identifies the types of
management actions that are currently being taken by DRP staff or others, and
identifies the current level of monitoring effort. The codes used under the column
headings for management actions and monitoring level are defined following the
table. Explanations for federal and state status as well as FNAI global and state
rank are provided in Addendum 6.

Tier 2. Targeted Presence/Absence: includes monitoring methods/activities that are specifically intended to document
presence/absence of a particular species or suite of species.
Tier 3. Population Estimate/Index: an approximation of the true population size or population index based on a widely accepted
method of sampling.
Tier 4. Population Census: A complete count of an entire population with demographic analysis, including mortality,
reproduction, emigration, and immigration.
Tier 5. Other: may include habitat assessments for a particular species or suite of species or any other specific methods used as
indicators to gather information about a particular species.
Detailed management goals, objectives and actions for imperiled species in this
park are discussed in the Resource Management Program section of this component
and the Implementation Component of this plan.
Exotic and Nuisance Species
Exotic species are plants or animals not native to Florida. Invasive exotic species
are able to out-compete, displace or destroy native species and their habitats, often
because they have been released from the natural controls of their native range,
such as diseases, predatory insects, etc. If left unchecked, invasive exotic plants
and animals alter the character, productivity and conservation values of the natural
areas they invade.
Exotic animal species include non-native wildlife species, free ranging domesticated
pets or livestock, and feral animals. Because of the negative impacts to natural
systems attributed to exotic animals, the DRP actively removes exotic animals from
state parks, with priority being given to those species causing the greatest
ecological damage.
In some cases, native wildlife may also pose management problems or nuisances
within state parks. A nuisance animal is an individual native animal whose presence
or activities create special management problems. Examples of animal species from
which nuisance cases may arise include venomous snakes or raccoons and
alligators that are in public areas. Nuisance animals are dealt with on a case-by-
case basis in accordance with the DRP’s Nuisance and Exotic Animal Removal
Standard.
Detailed management goals, objectives and actions for management of invasive
exotic plants and exotic and nuisance animals are discussed in the Resource
Management Program section of this component.
Exotic plants will continue to be a resource management issue at the park due to its
close proximity to urban landscaping and the size and location of exotic infestations
within park boundaries. One of the overall goals for the park is to achieve a
maintenance phase for each management zone. Due to the efforts of DRP staff
either through funding contractor projects or by conducting in-house treatment of
infested areas, the entire park is experiencing a maintenance phase of 83 percent
as of this writing. No additional exotic plant surveys are required however staff will
45
note the presence of any exotic vegetation while conducting routine duties.
Several large projects have helped to achieve this successful exotic removal
program at the park. Previously, the largest problem was pockets of Brazilian
pepper (Schinus terebinthifolius) in various parts of the hammock community. In
2006 a contractor project was funded by DEP’s Bureau of Invasive Plant
Management (BIPM) to remove 5.5 acres of heavily infested Brazilian Pepper in
management zone MB-02. The project was in the hammock in the northwest area
of the management zone. In 2007 another contractor project was funded by DRP to
treat 60 acres of hammock in zone MB-02. Species that were treated included
Brazilian pepper, java plum (Syzygium cumini), bishopwood (Bischofia javanica),
Australlian umbrella tree (Schefflera actinophylla), carrotwood (Cupaniopsis
anacardioides), Surinam cherry (Eugenia uniflora) and areca palm (Dypsis
lutescens). A contractor project in 2009 funded by the DRP targeted 13 acres in
management zone MB-05 and 12 acres in zone MB-06. The treatment area was the
hammock/beach dune from the top of the dune line west to the mangrove fringe.
Species that were treated include Brazilian pepper, beach naupaka (Scaevola
taccada), carrotwood, bowstring hemp (Sansevieria hyacinthoides), rosary pea
(Abrus precatorius) and Portia tree (Thespesia populnea). Principally, maintenance
and monitoring of these areas are conducted by DRP staff on regular intervals or as
resources allow. However, in 2013 a contractor project funded by the USFWS
Coastal Ecosystem Grant through the Treasure Coast Cooperative Invasive Species
Management Area group (TC CISMA) provided retreatment of the same areas that
were treated in 2009.
One of the major obstacles for the exotic control and removal program at Munyon
Island is accessibility which is limited to watercraft. There are additional concerns
and issues that must be addressed for all projects since they are limited by
logistics, the scope of work and the equipment that can be transported. This often
increases the funding that is required for large-scale restoration projects. Once on
the island, treating certain exotic infestations can be challenging because some
areas of the natural communities are isolated and inaccessible. However, because
of the cultural resources and the high costs of previous restoration projects, exotic
removal on Munyon Island remains a high priority for the park.
Many invasive exotic plants occur on and adjacent to disturbed land. Threats for
new invasions come from several sources: exotics already established in the park,
seed dispersal by natural means (birds, wind, water, etc.) and neighboring
developments. These areas are a high priority for exotic plant treatment wherever
feasible because they threaten rare habitats and function as a seed source.
Exotic animal species include non-native wildlife species, free ranging domesticated
pets or livestock, and feral animals. Because of the negative impacts to natural
systems attributed to exotic animals, the DRP actively removes exotic animals from
state parks, with priority being given to those species causing the greatest
ecological damage.
Non-native lizards including green iguanas, knight anoles and curly tail lizards have
46
all been documented at MacArthur Beach or near the park’s boundary. Non-native
reptiles pose a risk to native flora and fauna and should be removed by park staff
when feasible.
The red lionfish, Pterois volitans, is an Indo-Pacific marine fish that has been
recently introduced to the east coast of the United States including coastal Florida,
which many believe to be the site where the first lionfish was introduced. Lionfish
were first observed in park waters in 2010. They are an ambush predator that
prefers the ledges and crevices of the marine consolidated substrate. However,
lionfish are able to tolerate salinity differences over a large range from ocean to
brackish waters. Consequently, individuals have been removed from the dock at
Munyon Island. Lionfish are being found in the mangrove swamps of the Lake
Worth Lagoon. This is particularly disturbing since these mangrove swamps serve
as a nursery for important commercial and recreational fish species. Currently, DRP
staff are able to manage and remove the small numbers of lionfish that have been
found in the park. The majority of removals have occurred on the near shore reef,
but one lionfish was removed from the dock at Munyon Island.
Coyotes (Canus latrans) have established a population of unknown size in natural
areas north of the park. They travel south along county beaches destroying marine
turtle nests and feeding on turtle eggs. Coyotes have been photographed on the
park beach using motion sensitive cameras. Staff have observed a coyote feeding
on emerging hatchlings. In addition to the threat posed to imperiled marine turtles,
coyotes can spread disease such as distemper, parvo virus, hepatitis, mange and
rabies. Coyotes can also carry parasites like fleas, ticks, mites and worms. Coyotes
are now the predominant predator at the park and depredate more turtle nests per
year than all other predators.
Raccoons (Procyon lotor) are an abundant native species that impact sea turtle
conservation at many Florida beaches through nest depredation (Stancyk, 1982).
Compounding the problem, raccoon populations flourish in association with humans
because they often receive artificial support through refuse or direct feeding (Smith
and Engeman, 2002). They are one of the top predators on marine turtle nests at
John D. MacArthur Beach State Park preying on eggs and hatchlings. Like coyotes,
raccoons can spread disease such as distemper, parvo virus, hepatitis, mange and
rabies, and carry the same parasites.
Monitoring of nest predation is noted during daily nesting surveys. In an effort to
reduce predation rates and help in the recovery of the three listed species of sea
turtle, a trap and removal program has been implemented at the park (see Goals
and Objectives). All predators trapped under this program are removed according
to the protocols set forth in the Florida Park Service Operations Manual. Predator
removal programs have proven very successful. A study was conducted on The
Hobe Sound National Wildlife Refuge (HSNWR), which forms the southern boundary
of the St Lucie Inlet Preserve State Park. Prior to a predator control program,
historical nest predation at HSNWR was 95%. Consequently, predator control was
identified as the most important conservation tool at HSNWR, and predator removal
program was implemented in the early 2000’s. Predator control optimized by
47
predator monitoring led to highly successful results whereby predation had been
reduced to low levels (7–13.5% of monitored nests) in 2002 and 2003 (Engeman
and Smith, 2006).

Special Natural Features
The tropical maritime hammock at John D. MacArthur Beach State Park represents
one of the best examples of this community in Palm Beach County. The hammock
has a diverse assemblage of tropical trees and understory making it an ideal stop
over for many migratory bird species. This community is listed by FNAI as imperiled
in Florida with fewer than 253 recorded locations (FNAI, 1999). Generally, because
of the cooler weather, tropical species rapidly decline from Palm Beach County
northward along the coast to Cape Canaveral. At the park, the vegetation is
primarily tropical (mastic and pigeon plum) with some temperate (live oak and red
bay) plants. Commercial and residential development along the southeast coast of
Florida have greatly reduced and fragmented this community. The examples seen in
south Florida today represent remnants of a once extensive system. Because of the
desirability for development of the remaining coastal property in south Florida, it is
certain that the remaining examples of this community will become even more
endangered outside of protected areas.
A patchy reef system comprised of exposed limestone from the Anastasia formation
runs parallel to the shore and is accessible from the beach. Many park visitors take
the opportunity to explore this near shore reef by snorkel. Over 90 species of fish
have been identified using the rocky outcrops for shelter, food and resting. Marine
turtles are also seen resting and foraging along the reef.
Aggregations of worm reefs can also be found on the near shore reef. Worm reefs
are listed as an imperiled natural community both globally and statewide. They are
constructed by a tropical marine worm (Phragmatopoma lapidosa) that cements
50
together grains of sand with a protein to form narrow tubes. These reefs grow as
larvae build on the existing tubes. The worm reefs in the park are small in
comparison to other areas but are in excellent condition.
The beach provides critical nesting habitat for three imperiled marine turtle species:
the threatened loggerhead sea turtle, Caretta caretta, the endangered green sea
turtle, Chelonia mydas, and the endangered leatherback sea turtle, Dermochelys
coreacea. John D. MacArthur Beach State Park averages a higher nesting rate than
any other Florida State Park and serves as the primary nesting beach in southeast
Florida.
The park also contains one of the best examples of a mangrove fringed shoreline
and mangrove swamp in Palm Beach County. The park has one of the longest
mangrove fringed shorelines in the Lake Worth Lagoon. In general, red mangroves
are typically found in the intertidal zone, while black mangroves are dominant in
the upper portion of the intertidal zone (Odum and McIvor, 1990). White
mangroves are usually found in patches near a natural disturbance and occur in
less frequently flooded areas of the mangrove community. This ecosystem serves
as an important nursery for fishes and invertebrates as well as offering protection
to uplands by suppressing storm surges. In addition, the mangrove community is
an important nesting and roosting site for many wading birds.
The seagrass beds found in the calm waters of Lake Worth Cove, are one of the
most productive and diverse natural communities at the park providing food and
shelter for a variety of economically important recreational and commercial
vertebrate and invertebrate species.
All seven of Florida’s seagrass species were found in the Cove, including the
federally threatened species Halophila johnsonii (Johnson’s seagrass) as well as
Ruppia maritima (wigeongrass), a species which has never been documented within
the Cove and rarely documented within Lagoon remote from freshwater sources.
(Chesnes, et al, 2011). Lake Worth Cove has the highest seagrass diversity of any
area in Lake Worth Lagoon and, along with the Indian River Lagoon, has the
greatest seagrass diversity of any estuary in the Western Hemisphere (Chesnes, et
al, 2011).
Several imperiled species utilize the estuarine seagrass beds at the park. In 1998,
Johnson’s seagrass became the first and only seagrass listed as threatened under
the Endangered Species Act. Juvenile green turtles are often observed feeding on
submerged aquatic vegetation within Lake Worth Lagoon. The Florida manatee
(Trichechus manatus latirostris), a subspecies of the West Indian manatee
(Trichechus manatus), is often observed foraging and cavorting in the shallow
seagrass beds.

Cultural Resources
This section addresses the cultural resources present in the park that may include
archaeological sites, historic buildings and structures, cultural landscapes and
collections. The Florida Department of State (FDOS) maintains the master inventory
of such resources through the Florida Master Site File (FMSF). State law requires
that all state agencies locate, inventory and evaluate cultural resources that appear
to be eligible for listing in the National Register of Historic Places. Addendum 7
contains the FDOS, Division of Historical Resources (DHR) management procedures
for archaeological and historical sites and properties on state-owned or controlled
properties; the criteria used for evaluating eligibility for listing in the National
Register of Historic Places, and the Secretary of Interior’s definitions for the various
preservation treatments (restoration, rehabilitation, stabilization and preservation).
For the purposes of this plan, significant archaeological site, significant structure
and significant landscape means those cultural resources listed or eligible for listing
in the National Register of Historic Places. The terms archaeological site, historic
structure or historic landscape refer to all resources that will become 50 years old
during the term of this plan.
Condition Assessment
Evaluating the condition of cultural resources is accomplished using a three-part
evaluation scale, expressed as good, fair and poor. These terms describe the
present condition, rather than comparing what exists to the ideal condition. Good
describes a condition of structural stability and physical wholeness, where no
obvious deterioration other than normal occurs. Fair describes a condition in which
there is a discernible decline in condition between inspections, and the wholeness or
physical integrity is and continues to be threatened by factors other than normal
wear. A fair assessment is usually a cause for concern. Poor describes an unstable
condition where there is palpable, accelerating decline, and physical integrity is
being compromised quickly. A resource in poor condition suffers obvious declines in
physical integrity from year to year. A poor condition suggests immediate action is
needed to reestablish physical stability.
Level of Significance
Applying the criteria for listing in the National Register of Historic Places involves
the use of contexts as well as an evaluation of integrity of the site. A cultural
resource’s significance derives from its historical, architectural, ethnographic or
archaeological context. Evaluation of cultural resources will result in a designation
of NRL (National Register or National Landmark Listed or located in an NR district),
NR (National Register eligible), NE (not evaluated) or NS (not significant) as
indicated in the table at the end of this section.
There are no criteria for determining the significance of collections or archival
material. Usually, significance of a collection is based on what or whom it may
represent. For instance, a collection of furniture from a single family and a
particular era in connection with a significant historic site would be considered
52
highly significant. In the same way, a high-quality collection of artifacts from a
significant archaeological site would be of important significance. A large herbarium
collected from a specific park over many decades could be valuable to resource
management efforts. Archival records are most significant as a research source.
Any records depicting critical events in the park’s history, including construction
and resource management efforts, would all be significant. The following is a
summary of the FMSF inventory. In addition, this inventory contains the evaluation
of significance.
Prehistoric and Historic Archaeological Sites
Desired future condition: All significant archaeological sites within the park that
represent Florida’s cultural periods or significant historic events, or persons are
preserved in good condition in perpetuity, protected from physical threats and
interpreted to the public.
Description: The park lies within the Circum-Glades archeological region of Florida.
Proximity to the ocean, estuarine and freshwater environments, made the coastal
zone an important region during much of the prehistoric period supplying many
necessary resources such as food, water and tools. The aboriginal populations living
in the vicinity of the park were the Ais and Jaega. Both of these small groups
inhabited the lagoons and inlets of the south Atlantic during the time when the
Spanish were increasing their explorations of Florida. Repeated conflicts with the
Europeans and exposure to foreign diseases resulted in their decimation and
dispersal by the mid eighteenth century.
Although Spanish explorers came to the area in the sixteenth century, Palm Beach
County was not settled until somewhat late in the nineteenth century when
permanent homesteads were established. Within the park, the most notable
homestead was located on Munyon Island.
Munyon Island was once referred to by the Seminoles as “Nuctsachoo” meaning
“pelican.” This was the largest colonial water bird rookery in the area. In 1874,
plume hunters killed or frightened the birds away and they never returned.
Munyon Island was acquired from the State in 1889 by a couple named Pitts and
was renamed Pitts Island. The Pitts built a large house at the south end of the
island and planted many exotic, ornamental shrubs and fruit trees. The island was
the subject of many articles in national magazines and reported to be “the most
picturesque spot” in Florida.
In 1901, Dr. James M. Munyon acquired the island from the Pitts. Dr. Munyon had
made his fortune selling patent medicines in the northeast. He added to the
landscaping, put in shell roads and enlarged the Pitts’ house to five stories
renaming it the “Hygeia Hotel.” He catered to many ailing, wealthy northerners,
who came for the scenery, healthful sulfur water, and fermented papaya juice
called “Munyon Paw-Paw” tonic.
53
The hotel and some of the grounds burned in 1915. The island then remained
largely uninhabited, and the ornamental garden and shrubs languished from storms
and neglect. In 1936, and again in 1959-60, spoil material dredged from Lake
Worth was placed along the western edge of the island almost tripling its original
size.
The next owner of the island and the remainder of the park property was John D.
MacArthur, for whom the park is named. He was a billionaire when he passed away
in 1978. MacArthur made his fortune in insurance and real estate and passed on
the bulk of his fortune to the John D. and Catherine T. MacArthur Foundation, from
which the state received the park property in 1981.
The Florida Master Site File lists four historic archeological sites within the
boundaries of John D. MacArthur Beach State Park.
The largest site encompasses all of Munyon Island (PB00079) and is listed as a
historic refuse site that contains remnants of the Hygeia Hotel. The hotel was
operated by Dr. Munyon as a health resort during the 1890’s. The only remains of
the hotel are some of the foundation stones and a small section of seawall made
from native rock. These remains are located on the south end of the island. The
seawall and old dock alignment are exposed to wave action and are threatened by
erosion. In addition to the hotel site, subsequent surveys have identified an old
homestead site dating from the mid 1800’s and an Indian midden.
The next site (PB00214) was uncovered during the 1984 preconstruction survey
and is described as an aboriginal midden located in the primary dune system. This
is a fairly large midden that extends for over 100 feet along the dune and has had
several pieces of Glades Plain pottery recovered, as well as fish and turtles bones.
This site was further studied in 1988 and given a date of Glades III. This is a
significant site merely from its location on the ecotone between a once freshwater
lake (Lake Worth Cove) and the salt water/beach environment. It could potentially
provide useful information on prehistoric food gathering and dietary habits in these
environments. The site appears to have been utilized for a long period and might
reveal how adaptive changes occurred through time.
The Singer Island Midden 3 (PB06298) is located along the shore of the Lake Worth
Lagoon in the vicinity of the park shop compound. It appears to be a relatively large
shell midden. This area is listed as partially disturbed, but with large undisturbed
areas. It is thought that this midden dates to the same period as PB00214. It is
believed that this site was used for the collection of oysters in Lake Worth while PB
00214 was used for harvesting marine turtles, marine foods, and materials from
ship wrecks. This site produced St. Johns Check Stamped sherds and large amount
of oysters.
Another site (PB00215) that is listed as a historic refuse site is located on the edge
of A1A in a small grove of palm trees. This site is marked by a broken concrete slab
and fragments of 19th century bottle glass and ceramics. It is believed this site was
associated with Munyon Island.
54
A predictive model for John D. MacArthur Beach State Park was completed in 2013.
Although the majority of the park (43.19%) was delineated as having lower
sensitivity valuation, a new archeological site was recorded to the FMSF. Site
8Pb16069, an unspecified structure ruin comprised of a small rectangular concrete
and mortar foundational wall feature (measuring approximately 6 x 6 ft., was
recorded using GPS point data and photographs. The site is at the northern end of
the park and in the general vicinity of the prehistoric site 8Pb6298.
Condition Assessment: The Singer Island Midden 3 (PB06298) and site PB00215 are
in good condition and are located in areas where there is minimal activity or
erosion. In addition, the Singer Island Midden 3 is afforded additional protection
from vandalism due to its close proximity to the park residences and the shop
compound.
The aboriginal midden, Singer Island Midden II (PB00214), on the west face of the
primary dune is threatened by the seasonal beach erosion of the primary dune
system. The condition of this site is fair. The site has been significantly damaged by
hurricanes and in some areas the layers of midden are exposed. Every year, the
pattern of winter and tropical storms relentlessly strike the Florida coast. The park
beach erodes and accretes with this cyclic pattern. DRP has planted the area in
front of Singer Island Midden II with native beach vegetation in an effort to create a
buffer of dunes.
The majority of Munyon Island (PB00079) is in good condition. The seawall at
Munyon is exposed to wave action passing boats and threatened by erosion.
Munyon Island is located along the ICW in an area that experiences a high volume
of vessel traffic. The development of dock facilities on the island have exacerbated
erosion along the western side including seawall.
General Management Measures: It is the assessment of DRP that neither of the two
threatened sites: Singer Island Midden II (PB00214) and Munyon Island (PB00079),
will be able to attain a good desired future condition. Both sites are affected by
environmental conditions that are beyond the scope of management for the park.
Hurricanes, tropical storms and strong winter storms impact the park every year. It
is impossible to predict with certainty when and where these destructive natural
forces will strike and imprudent to believe that available management measures will
withstand these forces. In addition to the erosion caused by storms, Munyon Island
also experiences erosion from the wave action caused by watercraft of varying size
from jet skis to large yachts.
The location of the park also makes it difficult to implement management strategies
for achieving a good desired future condition. The park is situated on a barrier
island surrounded by two bodies of water: the Atlantic Ocean and the Lake Worth
Lagoon, that extend far beyond the boundaries of the park. Management of these
systems is complex.
55
The park will consider all options to determine which, if any, management strategy
will be successful without further impacting the natural resources. To stabilize the
beach, the park will continue to plant native vegetation in an effort to promote the
formation of dunes. The park will also consider other measures such as installing
small wooden picket fences to promote dune formation. The park will continue to
support efforts to regulate the speed of vessels in this area of the ICW. Currently,
the recommend treatment for all 4 archeological sites in the park is preservation. In
addition all of the sites will be monitored, any stabilization issues addressed, and
additional information or data relative to any of the sites submitted to DHR/FMSF.
Historic Structures
Desired future condition: All significant historic structures and landscapes that
represent Florida’s cultural periods or significant historic events or persons are
preserved in good condition in perpetuity, protected from physical threats and
interpreted to the public.
Description: No historical structures are located on John D. MacArthur Beach State
Park.
Detailed management goals, objectives and actions for the management of cultural
resources in this park are discussed in the Cultural Resource Management Program
section of this component. Table 4 contains the name, reference number, culture or
period, and brief description of all the cultural sites within the park that are listed in
the Florida Master Site File. The table also summarizes each site’s level of
significance, existing condition and recommended management treatment. An
explanation of the codes is provided following the table.
Collections:
Desired future condition: All historic, natural history and archaeological objects
within the park that represent Florida’s cultural periods, significant historic events
or persons, or natural history specimens are preserved in good condition in
perpetuity, protected from physical threats and interpreted to the public.

Resource Management Program
Management Goals, Objectives and Actions
Measurable objectives and actions have been identified for each of the DRP’s
management goals for John D. MacArthur Beach State Park. Please refer to the
Implementation Schedule and Cost Estimates in the Implementation Component of
this plan for a consolidated spreadsheet of the recommended actions, measures of
progress, target year for completion and estimated costs to fulfill the management
goals and objectives of this park.
While, the DRP utilizes the ten-year management plan to serve as the basic
statement of policy and future direction for each park, a number of annual work
plans provide more specific guidance for DRP staff to accomplish many of the
resource management goals and objectives of the park. Where such detailed
planning is appropriate to the character and scale of the park’s natural resources,
annual work plans are developed for prescribed fire management, exotic plant
management and imperiled species management. Annual or longer- term work
plans are developed for natural community restoration and hydrological restoration.
The work plans provide the DRP with crucial flexibility in its efforts to generate and
implement adaptive resource management practices in the state park system.
The work plans are reviewed and updated annually. Through this process, the DRP’s
resource management strategies are systematically evaluated to determine their
effectiveness. The process and the information collected is used to refine
techniques, methodologies and strategies, and ensures that each park’s prescribed
management actions are monitored and reported as required by Sections 253.034
and 259.037, Florida Statutes.
The goals, objectives and actions identified in this management plan will serve as
the basis for developing annual work plans for the park. The ten-year management
plan is based on conditions that exist at the time the plan is developed. The annual
work plans provide the flexibility needed to adapt to future conditions as they
change during the ten-year management planning cycle. As the park’s annual work
plans are implemented through the ten-year cycle, it may become necessary to
adjust the management plan’s priority schedules and cost estimates to reflect these
changing conditions.
Natural Resource Management
Hydrological Management
Goal: Protect water quality and quantity in the park, restore hydrology to
the extent feasible and maintain the restored condition.
The natural hydrology of most state parks has been impaired prior to acquisition to
one degree or another. Florida’s native habitats are precisely adapted to natural
drainage patterns and seasonal water level fluctuations, and variations in these
58
factors frequently determine the types of natural communities that occur on a
particular site. Even minor changes to natural hydrology can result in the loss of
plant and animal species from a landscape. Restoring state park lands to original
natural conditions often depends on returning natural hydrological processes and
conditions to the park. This is done primarily by filling or plugging ditches,
removing obstructions to surface water “sheet flow,” installing culverts or low-water
crossings on roads, and installing water control structures to manage water levels.
Objective A: Conduct/obtain an assessment of the park’s hydrological
restoration needs.
There are no hydrological restoration needs at John D. MacArthur Beach State Park.
Although no specific hydrological management is necessary at the park, staff will
comply with best management practices to prevent further degradation of the
hydrological resources or other impacts to water resources offsite.
Action 1 Monitor water quality at the park
John D. MacArthur Beach State Park is surrounded by tidal wetlands (mangroves),
estuarine open water and marine systems. Water is perhaps the most important
influence on the uniqueness of a barrier island. Anything that degrades water
quality can affect the natural environment and visitors to the park.
The issue of maintaining good surface water quality in John D. MacArthur Beach
State Park extends beyond the park’s wetlands. Point sources and non-point
sources of surface water pollution coming into the park should be identified and
proposed to regulating agencies for remediation. Every effort should be made to
support acquisition programs for preservation of all wetlands within the unit’s
drainage basin.
DRP staff will continue to monitor the hydrological resources and continue its
tradition of close cooperation with state and federal agencies and independent
researchers engaged in estuarine research and monitoring programs in the area.
The Division will rely on agencies such as the SFWMD, FWC, and FDEP to keep it
apprised of any local declines in surface water quality or increases in saltwater
intrusion. Biological staff in District 5 will continue to monitor Environmental
Resource Permit (ERP) and Water Use Permit (WUP) requests for the region in order
to provide timely and constructive comments that will promote protection of the
park’s hydrological resources.
Action 2 Address a small outflow from affluent property to the North of
the park
The Lost Tree Village community is situated along the northern boundary of the
park. A small outflow from the community’s retention pond drains into the
mangrove swamp that, in turn, drains into Lake Worth Cove. DRP biologists will
collect water samples from the drainage for analysis. If results indicate that the
outflow is adversely impacting the natural resources of the park, state and county
59
regulatory agencies will be notified of the violation and enforcement proceedings
will be undertaken.
Natural Communities Management
Goal: Restore and maintain the natural communities/habitats of the park.
The DRP practices natural systems management. In most cases, this entails
returning fire to its natural role in fire-dependent natural communities. Other
methods to implement this goal include large-scale restoration projects as well as
smaller scale natural communities’ improvements. Following are the natural
community management objectives and actions recommended for the state park.
Prescribed Fire Management
Prescribed fire is used to mimic natural lightning-set fires, which are one of the
primary natural forces that shaped Florida’s ecosystem. Prescribed burning
increases the abundance and health of many wildlife species. A large number of
Florida’s imperiled species of plants and animals are dependent on periodic fire for
their continued existence. Fire-dependent natural communities gradually
accumulate flammable vegetation; therefore, prescribed fire reduces wildfire
hazards by reducing these wild land fuels.
All prescribed burns in the Florida state park system are conducted with
authorization from the FDACS, Florida Forest Service (FFS). Wildfire suppression
activities in the park are coordinated with the FFS.
Objective A: Within 10 years, have 0 acres of the park maintained within
the optimum fire return interval.
Prescribed burning has not been conducted at John D. MacArthur Beach State Park.
There are no fire dependent natural communities and no natural communities that
will accept fire except for the maritime hammock. Natural fires in maritime
hammock probably occur no more often than once every 26 to 100-year period;
consequently, prescribed fire is not planned for the unit. Since no communities will
be managed through prescribed burning, no annual burn plan is required.
Natural Community Restoration
In some cases, the reintroduction and maintenance of natural processes is not
enough to reach the desired future conditions for natural communities in the park,
and active restoration programs are required. Restoration of altered natural
communities to healthy, fully functioning natural landscapes often requires
substantial efforts that may include mechanical treatment of vegetation or soils and
reintroduction or augmentation of native plants and animals. For the purposes of
this management plan, restoration is defined as the process of assisting the
recovery and natural functioning of degraded natural communities to desired future
60
condition, including the re-establishment of biodiversity, ecological processes,
vegetation structure and physical characters.
Examples that would qualify as natural community restoration, requiring annual
restoration plans, include large mitigation projects, large-scale hardwood removal
and timbering activities, roller-chopping and other large-scale vegetative
modifications. The key concept is that restoration projects will go beyond
management activities routinely done as standard operating procedures such as
routine mowing, the reintroduction of fire as a natural process, spot treatments of
exotic plants, and small-scale vegetation management.
Objective B: Conduct habitat/natural community restoration activities on 1
acre of beach natural community
Action 1 Develop/update site specific restoration plan
Action 2 Implement restoration plan
A boat dock facility was completed in 2012 on Munyon Island as part of a statewide
program to increase boater access on public lands. The entire structure is an L-
shaped concrete pier extending from the beach on Munyon Island with 20 floating
boat slips on the inside. The proximity of Munyon Island to the ICW was a concern
for the engineers. There is a high volume of vessel traffic creating numerous boat
wakes. In an effort to reduce wave attenuation to attain calm conditions at the
floating boat slips, boulders were placed under the L-shaped pier. Although the
placement of these boulders effectively reduced wave action from the boating
activity in the ICW, they have also exacerbated erosion of the island’s beach. The
boat dock has taken on the characteristics of a groin where sediment accretes at
the base of the structure while the beach erodes on either side. The erosion has
begun to threaten structures on the island forcing the park to close a beach access
and over 500 feet of visitor service boardwalk, as well as the Park Service dock.
District and park staff will work with DRP engineers to develop a restoration plan
that will ultimately restore the beach to preconstruction condition. Both biologists
and engineers will study the feasibility of altering the dock structure to reduce the
rate of erosion and define a mechanism that will allow sand to accumulate on the
beach. Developing a restoration plan that will involve this type of skilled labor is
beyond the scope of this document. Regardless of the type of restoration plan to be
developed and implemented, there will be an associated monitoring component
with protocols to help determine the success of the project.
Natural Community Improvement
Improvements are similar to restoration but on a smaller, less intense scale. This
typically includes small-scale vegetative management activities or minor habitat
manipulation. Following are the natural community/habitat improvement actions
recommended at the park.
61
Objective C: Conduct natural community/habitat improvement activities on
0 acres of natural communities
No natural community improvements are planned for this park.
Imperiled Species Management
Goal: Maintain, improve or restore imperiled species populations and
habitats in the park.
The DRP strives to maintain and restore viable populations of imperiled plant and
animal species primarily by implementing effective management of natural
systems. Single species management is appropriate in state parks when the
maintenance, recovery or restoration of a species or population is complicated due
to constraints associated with long-term restoration efforts, unnaturally high
mortality or insufficient habitat. Single species management should be compatible
with the maintenance and restoration of natural processes and should not imperil
other native species or seriously compromise park values.
In the preparation of this management plan, DRP staff consulted with staff of the
FWC’s Imperiled Species Management or that agency’s Regional Biologist and other
appropriate federal, state and local agencies for assistance in developing imperiled
animal species management objectives and actions. Likewise, for imperiled plant
species, DRP staff consulted with FDACS. Data collected by the USFWS, FWC,
FDACS and FNAI as part of their ongoing research and monitoring programs will be
reviewed by park staff periodically to inform management of decisions that may
have an impact on imperiled species at the park.
Ongoing inventory and monitoring of imperiled species in the state park system is
necessary to meet the DRP’s mission. Long-term monitoring is also essential to
ensure the effectiveness of resource management programs. Monitoring efforts
must be prioritized so that the data collected provides information that can be used
to improve or confirm the effectiveness of management actions on conservation
priorities. Monitoring intensity must at least be at a level that provides the
minimum data needed to make informed decisions to meet conservation goals. Not
all imperiled species require intensive monitoring efforts on a regular interval.
Priority must be given to those species that can provide valuable data to guide
adaptive management practices. Those species selected for specific management
action and those that will provide management guidance through regular
monitoring are addressed in the objectives below.
62
Objective A: Develop/Update baseline imperiled species occurrence
inventory lists for plants and animal
Objective B: Monitor and document 3 selected imperiled animal species in
the park.
Action 1 Implement monitoring protocols for 3 imperiled animal species
including marine turtles.
John D. MacArthur Beach State Park is an active participant in the statewide marine
turtle monitoring program. Monitoring protocols have been established by the
Florida Fish and Wildlife Conservation Commission (FWC). Three species of marine
turtles--loggerhead, green, and leatherback--use the beach for nesting. The park
serves as a state index and survey beach for nesting marine turtles. During the
nesting season, DRP staff conduct daily surveys of the beach recording the previous
night’s activities including the number of crawls, false crawls, species identification
and the number of nests. A representative sample of nests are designated for nest
productivity analysis to help determine the number of hatchlings produced from the
park. In addition to the daily surveys, the park also participates in the state’s
marine turtle stranding and salvage program that collects data on stranded, injured
or dead marine turtles. The data collected from the park are used by state and
federal agencies to formulate policy on nesting marine turtles.
Objective C: Maintain predation levels of marine turtle nests at or below
ten percent.
Action 1 Implement predator removal program to reduce predation levels
on imperiled marine turtles.
Predation from natural and introduce animal species is one of the major threats to
marine turtle nests and hatchlings. Raccoons and coyotes are the primary predators
in the park. Depredation is a part of the natural system and, to a certain extent,
compensated by the high reproductive output of sea turtles. However, predators
will sometimes become so proficient at finding and destroying nests that they may
threaten all the nests on a beach. Resource managers may sometimes control
predators such as raccoons by trapping and removing nuisance animals from the
beach. DRP staff use a predator trap and removal program to maintain predation
levels at or below the required ten percent that was established by the FWC.
Raccoons are opportunistic predators that have adapted well to coexist in the urban
developments throughout Florida. Scientific documentation indicates that certain
behavior is learned and passed on from adult raccoons to their offspring. During the
marine turtle nesting season, the population of raccoons raiding nests on the beach
increases. For these reasons, the screening does not always prevent nest
depredation by raccoons, so it becomes necessary to remove the nuisance predator
from the park. The predator removal program is an effective means of controlling
nest depredation and is administered by the United States Department of
Agriculture.
63
Objective D: Minimize coastal armament and other impediments to nesting
by working closely with regulatory and coastal engineering agencies.
Action 1 The DRP will work closely with other agencies and contractors to
minimize impacts to nesting turtles by continuing to conduct
nesting surveys to ensure work is restricted to non-nesting
season.
Beach nourishment projects alter the physiology and topography of the beach and
pose another threat to nesting marine turtles. Following beach nourishment, a
certain amount of scarping will take place along the mean high-water line where
the waves continuously erode the recently deposited beach sand. Over time, the
height and severity of the escarpments will decrease to form a more gradual slope.
Depending upon the severity, these escarpments can be a hindrance to nesting
marine turtles by preventing their access to the beach. Immediately following a
beach nourishment project, nesting frequencies drastically decrease. It may take as
long as three years for nesting frequencies to return to levels experienced prior to
beach nourishment.
Objective E: Monitor and document 2 selected imperiled plant species in
the park.
Action 1 Implement monitoring protocols for 2 imperiled plant
species including Johnsons’ seagrass and sea lavender.
The current seagrass monitoring program at the park was implemented in 2010 and
has established protocols for identifying the species and abundance of all
seagrasses in Lake Worth Cove including Johnson’s seagrass. The park has
partnered with a variety of stakeholders including faculty and undergraduate
research assistants from Palm Beach Atlantic University, DRP staff, scientists and
volunteers. Monitoring takes place biannually; during the winter to capture the
dormant season and at the end of summer to capture the growing season.
The population of sea lavender appears to be doing well in isolated pockets at the
base of the dunes. The population is susceptible to impacts from periodic tropical
storms. Park staff implemented a monitoring program for sea lavender in 2010 but
was unable to continue the program because of a lack of resources. However, in
2014, the park established baseline data recording the location of all individual
colonies, the height and width of the colony and the current health. Monitoring will
be conducted biannually and following any tropical storm.
Exotic Species Management
Goal: Remove exotic and invasive plants and animals from the park and
conduct needed maintenance control.
The DRP actively removes invasive exotic species from state parks, with priority
being given to those causing the ecological damage. Removal techniques may
include mechanical treatment, herbicides or biocontrol agents.
64
Objective A: Annually treat 3 acres of exotic plant species in the park.
Action 1 Annually develop/update exotic plant management work plan.
Action 2 Implement annual work plan by treating 3 acres in park,
annually, and continuing maintenance and follow-up treatments, as
needed.
The DRP defines the acreage of exotic plants proposed for treatment as an infested
area. An infested area is the approximate area of land (in acres) covered by the
invasive plants if the plants were accumulated into one area. This distinction more
accurately estimates the actual quantity of plants removed. DRP staff will conduct
exotic removal treatment at the park for Category I and II invasive exotics. The
park will annually identify areas where exotic treatment will take place during the
course of the year. The goal will be to treat exotic species that either have re-
sprouted or have recruited into natural communities following previous exotic
removal treatments. All communities, including developed, will be targeted.
Continuous monitoring and maintenance activities to control re-growth and new
infestations will be implemented by DRP staff. Vegetative surveys will continue to
be conducted to ascertain the presence of new exotic species.
Objective B: Implement control measures on 1 exotic animal species in the
park.
Action 1 Conduct biannual lionfish surveys
Lionfish were first sighted in park waters in 2009. DRP biologists have organized
lionfish surveys with park staff and biologists from other divisions and agencies to
locate and remove all fish that are found. These surveys are conducted periodically,
and they have maintained the lionfish population in the park at manageable levels.
Fortunately, the park has not experienced the great numbers of these fish that
other areas have seen. The DRP follows policies and guidelines for managing this
invasive exotic established by FWC.
Cultural Resource Management
Cultural resources are individually unique, and collectively, very challenging for the
public land manager whose goal is to preserve and protect them in perpetuity. The
DRP will implement the following goals, objectives and actions, as funding becomes
available, to preserve the cultural resources found in John D. MacArthur Beach
State Park.
Goal: Protect, preserve and maintain the cultural resources of the park.
The management of cultural resources is often complicated because these
resources are irreplaceable and extremely vulnerable to disturbances. The advice of
historical and archaeological experts is required in this effort. All activities related to
land clearing, ground disturbing activities, major repairs or additions to historic
structures listed or eligible for listing in the National Register of Historic Places must
be submitted to the FDOS, Division of Historical Resources (DHR) for review and
comment prior to undertaking the proposed project. Recommendations may include
65
but are not limited to concurrence with the project as submitted, pre-testing of the
project site by a certified archaeological monitor, cultural resource assessment
survey by a qualified professional archaeologist, modifications to the proposed
project to avoid or mitigate potential adverse effect. In addition, any demolition or
substantial alteration to any historic structure or resource must be submitted to the
DHR for consultation and the DRP must demonstrate that there is no feasible
alternative to removal and must provide a strategy for documentation or salvage of
the resource. Florida law further requires that DRP consider the reuse of historic
buildings in the park in lieu of new construction and must undertake a cost
comparison of new development versus rehabilitation of a building before electing
to construct a new or replacement building. This comparison must be accomplished
with the assistance of the DHR.
Objective A: Assess and evaluate 5 of 5 recorded cultural resources in the
park.
Action 1 Complete 5 assessments/evaluations of archaeological sites.
Park staff will complete assessments of all 5 known archaeological sites in the park.
Of these sites, 3 are in areas that limit threats to the current condition of the site.
The treatment plan calls for preservation. The remaining 2 sites have a treatment
plan that calls for preservation but also includes stabilization. The Singer Island
Midden located at the base of the dunes on the beach is subject to erosion from
seasonal storms. The Munyon Island seawall and old dock alignment are exposed to
wave action and are threatened by erosion. Photo points will be a useful tool to
compare the current condition of the 5 sites with previous evaluations. Park staff
will work closely with state archeologists to implement strategies to stabilize those
sites that are immediately threatened.
Objective B: Compile reliable documentation for all recorded historic and
archaeological resources.
Action 1 Ensure all known sites are recorded or updated in the Florida
Master Site File.
Beginning in 1984, there have been eight archaeological surveys of varying
intensity and scope within areas covered by the current park boundary. These
projects range from monitoring, to resource surveys by DHR archaeologists, to
CRAS projects and a Phase I Historical and Archaeological assessment involving the
Munyon Island and Hygeia Hotel vicinity of the park. In addition, a predictive model
was completed in 2013 that revealed a new archeological site that has since been
recorded in the Florida Master Site File (FMSF). The present model was created for
terrestrial site sensitivity only. The predictive model concludes that all of the
archaeological sites previously recorded with the FMSF, fall within high or medium
sensitivity areas for this park. The report also delineates some 43.19% of the park
areas as having lower sensitivity valuation.
66
Objective C: Bring 1 of 5 recorded cultural resources into good condition.
Action 1 Design and implement regular monitoring programs for 5
cultural sites.
Action 2 Create and implement a cyclical maintenance program for 1
cultural resource.
The park will work with state archeologists to design a monitoring program that will
enable staff to conduct annual monitoring of the 5 archeological sites located within
the park. Monitoring will also take place following episodic events such as tropical
storms/hurricanes to ascertain the damage to the site and what immediate action,
if any, is required to stabilize the site. The park acknowledges the historical
importance of these sites and the need for a monitoring program to determine each
sites’ current condition and to monitor improvements or deterioration of that
current condition. The monitoring program will also identify possible threats to the
site such as erosion and the management strategies required for the possible
stabilization and preservation of this archeological site. Such strategies would
include the planting of native vegetation to help promote dune formation.
A maintenance program will be implemented for 1 archeological site. The Singer
Island Midden is located on the beach at the base of the dunes and is susceptible to
erosion from tropical storms. This site is particularly significant because it is located
on an ecotone between a former freshwater lake (Lake Worth Cove) and the
saltwater/beach environment immediately to the east. It could potentially provide
useful information about prehistoric food gathering and dietary habits in these
environments. The site appears to have been occupied for an extended period and
might reveal how adaptive changes occurred through time. However, the location of
this site makes preservation and stabilization a challenge. Once implemented, the
monitoring program should help to guide the maintenance program. For example,
since this site is susceptible to erosion, monitoring the site after a tropical storm,
would identify the impacts to the site and the management strategies required for
stabilization. In this case, planting an assemblage of native vegetation to help
promote dune formation would be an appropriate strategy.
Special Management Considerations
Timber Management Analysis
Chapters 253 and 259, Florida Statutes, require an assessment of the feasibility of
managing timber in land management plans for parcels greater than 1,000 acres if
the lead agency determines that timber management is not in conflict with the
primary management objectives of the land. The feasibility of harvesting timber at
this park during the period covered by this plan was considered in context of the
DRP’s statutory responsibilities and an analysis of the park’s resource needs and
values. The long-term management goal for forest communities in the state park
system is to maintain or re-establish old-growth characteristics to the degree
practicable, with the exception of those communities specifically managed as early
successional.
67
A timber management analysis was not conducted for this park since its total
acreage is below the 1,000-acre threshold established by statute. Timber
management will be re-evaluated during the next revision of this management
plan.
Coastal/Beach Management
The DRP manages over 100 miles of sandy beach, which represents one-eighth of
Florida’s total sandy beach shoreline. Approximately one-quarter of Florida’s state
parks are beach-oriented parks and account for more than 60 percent of statewide
park visitation. The management and maintenance of beaches and their associated
systems and processes is complicated by the presence of inlets and various
structures (jetties, groins, breakwaters) all along the coast. As a result, beach
restoration and nourishment have become increasingly necessary and costly
procedures for protecting valuable infrastructure. Beach and inlet management
practices affect beaches for long distances on either side of a particular project.
DRP staff needs to be aware of and participate in the planning, design and
implementation of these projects to ensure that park resources and recreational use
are adequately considered and protected.
John D. MacArthur Beach State Park is located on Singer Island and has 1.8 miles
of beach. According to the DEP Bureau of Beaches and Coastal Systems, the beach
within the park is designated as a noncritically eroded area. For an erosion problem
area to be critical, there must exist a threat to or loss of one of four specific
interests – upland development, recreation, wildlife habitat, or important cultural
resources. Many areas have significant historic or contemporary erosion conditions,
yet the erosion processes do not currently threaten public or private interests.
These areas are therefore designated as non-critically eroded areas and require
close monitoring in case conditions become critical.
Although the beach is subjected to the seasonal erosion caused by summer
tropical storms and winter nor’easters, the park historically has not had to
pursue beach nourishment. Since the park is not located adjacent to an inlet,
jetties or other coastal armaments that disrupt the sediment transport system,
the park relies on the natural process of sand accretion to nourish its beach.
Three sea turtles: the threatened loggerhead sea turtle (Caretta caretta),
endangered green sea turtle (Chelonia mydas), and endangered leatherback sea
turtle (Dermochelys coreacea) use the park’s beach as nesting habitat to deposit
their eggs. The beach serves as habitat that is critical to the recovery of these
imperiled species. The park beaches also record numerous migratory bird species
that benefit from the undisturbed natural communities of the park that support
foraging, roosting, and sheltering, and the physical features necessary for
maintaining the natural processes that support these critical habitats.
68
The Anastasia formation is exposed along much of the park’s shoreline forming a
nearshore hardbottom habitat that is beneficial to the park and offers additional
recreational activities to park visitors. Biodiversity is much greater on hardbottom
habitats than on sandy bottom. The exposed rock provides a stable substrate for
epifauna such as macroalgae, soft corals and sponges. These heterotrophs, through
photosynthesis and filter and suspension feeding, provide basic organic material on
which much of the reef’s food web is based. Another sessile organism, sabellariid
worms form a unique reef type known as “worm reef”. These reefs are most often
formed in high energy surf zones and provide shoreline protection by reducing wave
energy on the beach. Such reefs are composed of loosely cemented sand particles
which are held together by a mucus secreted by the worms when building their
casing. Sabellariid worm colonies provide habitat for over 325 species of
invertebrates (Nelson 1989). The nearshore hardbottom is also used by adult sea
turtles for foraging, resting and mating and by turtle hatchlings for refuge from
predators when they first enter the ocean after emergence from nest cavities. In
addition, the hardbottom community is utilized by numerous recreational and
commercial fish species, such as tarpon and snapper, lobsters and a variety of
tropical fish.
In an effort to provide additional protection for this important natural community,
the park has established a 400 ft. sovereign submerged management area that
extends along the entire beach. Management activities conducted within this 400 ft.
zone are designed to enhance the recovery of imperiled marine turtles, increase the
biological diversity of the park, increase shoreline protection, increase recreational
opportunities and enhance visitor experience to the park.
Public access to the beach is provided by the park via four dune crossovers.
However, many visitors access the beach by simply walking from the neighboring
beach or by anchoring their boats and swimming ashore. This is one of the few
undisturbed, natural beaches remaining in Palm Beach County and it has become a
very popular destination. Although the visitation rate is high, park staff have been
diligent in protecting beach vegetation by using signs and barriers to limit access to
designated foot paths. Whenever plants become available and as required, the
park, with the help of volunteers, for installation of native vegetation to help
protect sensitive cultural areas and promote the formation of dunes.
Systematic review of the DRP’s recreation and imperiled species policies as they
apply to beach management will assist in better understanding cumulative impacts.
Site-specific analysis and implementation of conservation measures should be a
high priority for John D. MacArthur Beach State Park. For example, the impacts
from disturbance may be lessened by restricting access to roosting and foraging
areas and enforcing the no-pet rule on the beach. In addition, educational materials
such as signs and brochures can provide valuable information, so the public
understands the need for conservation measures.
69
Arthropod Control Plan
All DRP lands are designated as “environmentally sensitive and biologically highly
productive” in accordance with Ch. 388 and Ch. 388.4111 Florida Statutes. If a
local mosquito control district proposes a treatment plan, the DRP works with the
local mosquito control district to achieve consensus. By policy of DEP since 1987,
aerial adulticiding is not allowed, but larviciding and ground adulticiding (truck
spraying in public use areas) is typically allowed. The DRP does not authorize new
physical alterations of marshes through ditching or water control structures.
Mosquito control plans temporarily may be set aside under declared threats to
public or animal health, or during a Governor’s Emergency Proclamation.
There is no arthropod control plan established for the John D. MacArthur Beach
State Park.
Sea Level Rise
Potential effects of sea level rise are now under study and will be addressed by
Florida’s residents and governments in the future. The DRP will stay current on
existing research and predictive models, in coordination with other DEP programs
and federal, state, and local agencies. The DRP will continue to observe and
document the changes that occur to the park’s shorelines, natural features,
imperiled species populations, and cultural resources. This ongoing data collection
and analysis will inform the DRP’s adaptive management response to future
conditions, including the effects of sea level rise, as they develop. Additional
concepts for addressing impacts of sea level rise are briefly described under the
Resiliency Planning section of the Land Use Component (see page 72).
Resource Management Schedule
A priority schedule for conducting all management activities that is based on the
purposes for which these lands were acquired, and to enhance the resource values,
is located in the Implementation Component of this management plan.
Land Management Review
Section 259.036, Florida Statutes, established land management review teams to
determine whether conservation, preservation and recreation lands titled in the
name of the Board of Trustees are being managed for the purposes for which they
were acquired and in accordance with their approved land management plans. The
considered recommendations of the land management review team and updated
this plan accordingly.
John D. MacArthur Beach State Park was subject to a land management review on
April 17, 1998. The review team made the following determinations:
•The land is being managed for the purpose for which it was acquired.
•The actual management practices, including public access, complied with the
management plan for this site.
73
LAND USE COMPONENT
Introduction
Land use planning and park development decisions for the state park system
are based on the dual responsibilities of the Florida Department of
Environmental Protection (DEP), Division of Recreation and Parks (DRP). These
responsibilities are to preserve representative examples of original natural
Florida and its cultural resources, and to provide outdoor recreation
opportunities for Florida's citizens and visitors.
The general planning and design process begins with an analysis of the natural
and cultural resources of the unit, and then proceeds through the creation of a
conceptual land use plan that culminates in the actual design and construction
of park facilities. Input to the plan is provided by experts in environmental
sciences, cultural resources, park operation and management. Additional input
is received through public workshops, and through environmental and
recreational-user groups. With this approach, the DRP objective is to provide
quality development for resource-based recreation throughout the state with a
high level of sensitivity to the natural and cultural resources at each park.
This component of the unit plan includes a brief inventory of the external
conditions and the recreational potential of the unit. Existing uses, facilities,
special conditions on use, and specific areas within the park that will be given
special protection, are identified. The land use component then summarizes the
current conceptual land use plan for the park, identifying the existing or
proposed activities suited to the resource base of the park. Any new facilities
needed to support the proposed activities are expressed in general terms.
External Conditions
An assessment of the conditions that exist beyond the boundaries of the unit
can identify any special development problems or opportunities that exist
because of the unit's unique setting or environment. This also provides an
opportunity to deal systematically with various planning issues such as location,
regional demographics, adjacent land uses and park interaction with other
facilities
John D. MacArthur Beach State Park is in North Palm Beach within Palm Beach
County about 5 miles east of Palm Beach Gardens, 10 miles south of Jupiter,
and 10 miles north of West Palm Beach in the southeast part of the state.
Approximately 1.4 million people live within 30 miles of the park (U.S. Census
2016).
74
The population of Palm Beach County is diverse in terms of demographic
characteristics. According to the U.S. Census Data (2016), approximately 46%
of residents in the county identify as black, Hispanic or Latino, or another
minority group. Approximately 42% of residents can be described as youth or
seniors (U.S. Census 2016). Persons of the working age (16 to 65 years old)
make up 62% of the population (U.S. Census 2016). Palm Beach County’s per
capita personal income at $34,846 is below the statewide average of $41,497
(U.S. Bureau of Economic Analysis 2016).
A significant amount of resource-based recreation opportunities are within 15
miles of John D. MacArthur Beach State Park. Jonathan Dickinson State Park
offers biking, camping, paddling, fishing, hiking, swimming, cabins, horse trails,
and wildlife viewing. Hobe Sound National Wildlife Refuge, a 1,035-acre refuge,
offers opportunities for public recreation, including nature trails and wildlife
observation, surf fishing, and beach use. Managed by the Florida Fish and
Wildlife Conservation Commission (FWC), the John C. and Mariana
Jones/Hungryland Wildlife and Environmental Area (WEA), Pal-Mar East, and
Loxahatchee Slough Natural Area provide biking, boating, camping, paddling,
hiking, and hunting opportunities.
Several parks and preserves managed by Palm Beach County are located in the
vicinity of the park. Palm Beach County is responsible for the management of
Pine Glades, Cypress Creek, Winding Waters, Frenchman’s Forest, Lake Park
Scrub, Snook Islands, and Juno Dunes Natural Areas. All properties offer
opportunities for biking, hiking, fishing, and paddling. The Jupiter Inlet
Lighthouse Outstanding Natural Area hosts nature trails, observation platforms,
and hiking trails. The South Florida Water Management District (SFWMD) allows
paddling, boating, hunting, fishing, and hiking through the Loxahatchee
River/Cypress Creek Management Area, and J.W. Corbett Wildlife Management
Area. Okeeheelee Park in West Palm Beach has equestrian and nature trails,
fishing piers, bike paths, and rental concessions for the public.
The park is located in the Southeast Vacation Region, which includes Broward,
Miami-Dade, Monroe, and Palm Beach counties (Visit Florida 2013). According
to the 2013 Florida Visitor Survey, approximately 17.3% of domestic visitors to
Florida visited this region. Roughly 87% visitors to the region traveled to the
Southeast for leisure purposes. The top activities for domestic visitors were
beach/waterfront and culinary/dining experiences. Summer was the most
popular travel season, but visitation was generally spread throughout the year.
Most visitors traveled by air (60%), reporting an average of 4.4 nights and
spending an average of $186 per person per day (Visit Florida 2013).
Florida’s Statewide Comprehensive Outdoor Recreation Plan (SCORP) indicates
that participation rates in this region for saltwater beach activities, visiting
archaeological and historic sites, nature study, picnicking, and bicycle riding are
75
higher than the state average with demand for additional facilities increasing
through 2020 (FDEP 2013).

Existing Use of Adjacent Lands
John D. MacArthur Beach State Park is bordered entirely by single-family
residential development. The park is bound to the east by the Atlantic Ocean
and to the west by the Intracoastal Waterway (Lake Worth). A1A runs along the
western border. The Intracoastal Waterway carries an abundance of cargo daily
76
and supports a variety of commercial and recreational activities. Recreation is
the main use of the waterway, including personal boats, water taxis, and tour
boats. To the west of the Intracoastal Waterway is Palm Beach Gardens. Along
the northern park border situated in residential development is a golf course
community, and a church is situated at the park entrance road.
Surrounding lands in the Village of North Palm Beach are largely residential and
commercial. Among the many winding neighborhoods in the village are
commercial developments including country clubs and restaurants. Recreational
spaces are not in short supply in the area which has many local parks and
natural areas.
Impacts of the adjacent residential areas to the park are minimal, as the John
D. MacArthur Beach State Park Greenline Overlay substantially reduces
potential impact from surrounding lands. The park also enjoys relative seclusion
from contaminants as the only directly adjacent parcels to the park exist on
narrow northern and southern boundaries.
Planned Use of Adjacent Lands
Surrounding properties directly to the north are designated for residential low-
density development, which continues inland on land in Palm Beach Gardens.
An institutional district is identified for the church property also on the northern
park boundary. To the south, land is designated for conservation purposes.
There are also high-rise residential complexes as you travel south on A1A from
the park. The Village of North Palm Beach has designated the future land use
for much of the land near the park as either high or low density residential, with
dispersed pockets of commercial and mixed-use parcels. All parcels surrounding
the park are unlikely to see significant change in the future in regard to land
use given that much of the area has seemingly reached maximum buildout.
The northern boundary of the park abuts the John D. MacArthur Beach State
Park Greenline Overlay, which is intended to protect park resources from
impacts caused by activities on adjacent lands. The overlay creates a buffer
from surface water runoff and groundwater contamination, potential
incompatible land use, and protects critical wildlife habitats (Palm Beach County
2014).
Palm Beach County is a member of the Treasure Coast Regional Planning
Council (TCRPC), which also includes St. Lucie, Martin, and Indian River
Counties. The council and county are committed to maintaining a balanced,
orderly sustainable economic growth (TCRPC 2012). Growth is being directed to
the east of the county to prevent sprawl from harming coastal resources.
Coastal communities are identified by the council for revitalization and
redevelopment programs. The council is cognizant of the rapid growth in the
area and incorporates solutions into its work to counter negative impacts of
rapid growth. TCRPC and the South Florida Regional Planning Council (SFRPC)
77
are collaborating on a long-range economic development plan for the six million
residents in South Florida.
Florida Greenways and Trails System (FGTS)
The Florida Greenways and Trails System (FGTS) is made up of existing,
planned and conceptual non-motorized trails, and ecological greenways that
form a connected, integrated statewide network. The FGTS serves as a green
infrastructure plan for Florida, tying together the greenways and trails plans
and planning activities of communities, agencies and non-profit organizations
throughout Florida. Trails include paddling, hiking, biking, multi-use and
equestrian trails. The Office of Greenways and Trails maintains a priority trails
map and gap analysis for the FGTS to focus attention and resources on closing
key gaps in the system.
In some cases, existing or planned priority trails run through or are adjacent to
state parks, or they may be in close proximity and can be connected by a spur
trail. State parks can often serve as trailheads, points-of-interest, and offer
amenities such as camping, showers and laundry, providing valuable services
for trail users while increasing state park visitation.
The Florida Circumnavigational Saltwater Paddling Trail, or the CT, spans 1,515
miles along Florida’s coast, from Pensacola to Fort Clinch. This trail is a
strategic long-term priority that will require the involvement of state and local
agencies alongside local stakeholders. Segment 19, a 29-mile link from Lake
Worth to Jonathan Dickinson State Park runs past the park through Lake Worth
Lagoon. Paddlers on the trail can utilize the park’s facilities and enjoy a number
of accessible recreational opportunities.
The park is also intersected by the East Coast Greenway, the longest biking and
walking route in the nation. An on-road routing portion of the East Coast
Greenway runs through the property and continues along A1A.
Property Analysis
Effective planning requires a thorough understanding of the unit's natural and
cultural resources. This section describes the resource characteristics and
existing uses of the property. The unit's recreation resource elements are
examined to identify the opportunities and constraints they present for
recreational development. Past and present uses are assessed for their effects
on the property, compatibility with the site, and relation to the unit's
classification.
78
Recreational Resource Elements
This section assesses the park’s recreational resource elements, those physical
qualities that, either singly or in certain combinations, can support various
resource-based recreation activities. Breaking down the property into such
elements provides a means for measuring the property's capability to support
potential recreational activities. This process also analyzes the existing spatial
factors that either favor or limit the provision of each activity.
Land Area
Across the park’s 440 acres, remarkable resources are preserved including
mangrove, estuarine grass bed, worm reef, and 121 acres of maritime
hammock. The combination of natural communities makes the park a robust
and vital component of the region. The maritime hammock in the park is a
rarity in SE Florida and has been identified as an exemplary site by the Florida
Natural Areas Inventory.
Water Area
The park is bounded on both its east and west sides by Lake Worth Lagoon and
the Atlantic Ocean and contains the entirety Lake Worth Cove. Visitors paddle
across Lake Worth Lagoon to access Munyon Island and explore the scenic
mangrove swamps throughout the park. The adjacent Atlantic beach affords
high quality aquatic opportunities. Other small navigable water bodies within
the park offer additional interpretation and recreation.
Shoreline
The park’s lagoon and cove shorelines are characterized by extensive mangrove
swamp which support abundant wildlife. Boaters and paddlers along the
mangroves enjoy a number of interpretive and recreational activities. The
Florida Circumnavigational Trail extends past the park through the intercoastal
waterway attracting paddlers into the park. One of the primary draws of the
park is its 1.5-mile Atlantic shoreline. Clear waters and a shallow reef feature
make this popular for swimming and snorkeling
Natural Scenery
The park interior contains scenic canopied use areas contrasting with the open
vistas from the boardwalks across Lake Worth Cove and the Atlantic Beach.
Parkwide, the scenery is characteristic of the Atlantic Coastal Ridge region.
79
Significant Habitat
Set in a highly urbanized area, the park protects and interprets a variety of
terrestrial and marine wildlife. The beach provides significant habitat for nesting
sea turtles and shorebirds. The calm waters of the lagoon as well as cove
provide refuge for manatees and expansive seagrass beds. The hammock
provides resting habitat for neotropical-migratory bird species.
Natural Features
The park facilitates access to three distinct natural features including Lake
Worth Cove, Munyon Island, and the Atlantic Beach, each offering unique
recreational experiences. Visitors traverse dense maritime hammock on both
the mainland and Munyon Island. The beach is popular for walking, shelling,
and swimming.
Archaeological and Historical Features
The cultural resources of the park tell a complex story of southeast Florida
history spanning centuries. Serving as a place for prehistoric sustenance,
cultural ceremonies, war, trade, commerce, and recreation- the park has been a
site of interest across the generations. Evidence of prehistoric use has been
identified by the shell middens in the park and the most tangible remnants of
historical occupation are on Munyon Island, which hosts the remains of the
Hygeia Hotel.
Assessment of Use
All legal boundaries, significant natural features, structures, facilities, roads and
trails existing in the unit are delineated on the base map (see Base Map).
Specific uses made of the unit are briefly described in the following sections.
Past Uses
Modern use of the property began in the 1880s by homesteaders and
horticulturalists who began enticing northern visitors with the unique sub-
tropical setting and beach landscape. In 1901 the property was acquired by Dr.
James M. Munyon who sequentially developed the Hygeia Hotel as a place of
healing. The hotel was situated amongst lush scenery and what the doctor
believed to be a fountain of youth brimming with healthful sulfuric waters. The
Hygeia Hotel operated until 1917 and the property largely remained dormant
until John D. Macarthur purchased the land in 1955.
80
Future Land Use and Zoning
The DRP works with local governments to establish designations that provide
both consistency between comprehensive plans and zoning codes and permit
typical state park uses and facilities necessary for the provision of resource-
based recreation.
The Palm Beach County Future Land Use designation for the park is Parks and
Recreation. These areas are designated to reflect developed or planned sites
owned by a governmental entity that provide the public an opportunity to
partake in a variety of recreational activities that may be active, passive, or
special in nature in a safe and convenient manner that is compatible with its
environs. The area surrounding the park has been designated as a Greenline
Overlay area by Palm Beach County. This designation is intended to protect
resources within park boundaries, such as water, wildlife populations, and the
aesthetic quality of recreation in this park, from impacts caused by activities on
adjacent land (Palm Beach County 2016).
The Village of North Palm Beach zones the park as Conservation and Open
Space (C-OS). The intent of this classification is to provide for land uses and
activities for the primary purpose of conserving or protecting natural resources
of environmental quality. This designation does not allow any building or
structures except those for normal operation and management including single-
family residential dwellings. The minimum lot size for each dwelling shall be at
least one acre of upland area (Village of North Palm Beach 2016). Existing land
use and zoning designations are consistent with current and projected future
uses of the park.
Current Recreational Use and Visitor Programs
Approximately 6,000 feet of shoreline on the Atlantic Ocean at John D.
MacArthur Beach State Park allow general beach recreation activities, including
walking, sunbathing, swimming, shoreline fishing, snorkeling and scuba diving.
Park facilities developed in the late 1980s provide safe, low-impact access to
this beach for thousands of visitors each year. Nature trails, picnicking facilities,
and the interpretive center provide visitors with a range of recreational,
interpretive and environmental education programs in the maritime hammock
area. The interpretive center features an exhibit area regarding coastal and
marine ecosystems, aquarium displays, audio-visual presentation room,
outdoor amphitheater, and restrooms. Since the park opened in 1989, an
ambitious environmental education program has evolved in response to the
unique character and quality of the natural systems and resources of the state
park. The park’s citizen support organization outfits visitors with kayaks to
explore the estuary.
81
John D. MacArthur Beach State Park recorded 149,982 visitors in FY
2018/2019. By DRP estimates, the FY 2018/2019 visitors contributed $13.3
million in direct economic impact, the equivalent of adding 187 jobs to the local
economy (FDEP 2019).
Other Uses
Munyon Island was used by the Army Corps of Engineers as a spoil site for
construction and maintenance of the Intracoastal Waterway. Spoil deposition
and staging of projects is now discounted. The park mainland includes a
segment of right-of-way for State Road A1A. No other non-park uses are
permitted.
Protected Zones
A protected zone is an area of high sensitivity or outstanding character from
which most types of development are excluded as a protective measure.
Generally, facilities requiring extensive land alteration or resulting in intensive
resource use, such as parking lots, camping areas, shops or maintenance areas,
are not permitted in protected zones. Facilities with minimal resource impacts,
such as trails, interpretive signs and boardwalks are generally allowed. All
decisions involving the use of protected zones are made on a case-by-case
basis after careful site planning and analysis.
At John D. MacArthur Beach State Park, all wetlands and floodplain as well as
known imperiled species habitat have been designated as protected zones. The
park’s current protected zone is delineated on the Conceptual Land Use Plan.

Conceptual Land Use Plan
The following narrative represents the current conceptual land use proposal for
this park. The conceptual land use plan is the long-term, optimal development
plan for the park, based on current conditions and knowledge of the park’s
resources, landscape and social setting (see Conceptual Land Use Plan). The
conceptual land use plan is modified or amended, as new information becomes
available regarding the park’s natural and cultural resources or trends in
recreational uses, in order to adapt to changing conditions. Additionally, the
acquisition of new parkland may provide opportunities for alternative or
expanded land uses. The DRP develops a detailed development plan for the
park and a site plan for specific facilities based on this conceptual land use plan,
as funding becomes available.
During the development of the conceptual land use plan, the DRP assessed the
potential impact of proposed uses or development on the park resources and
applied that analysis to determine the future physical plan of the park as well as
the scale and character of proposed development. Potential resource impacts
are also identified and assessed as part of the site planning process once
funding is available for facility development. At that stage, design elements
(such as existing topography and vegetation, sewage disposal and stormwater
management) and design constraints (such as imperiled species or cultural site
locations) are investigated in greater detail. Municipal sewer connections,
advanced wastewater treatment or best available technology systems are
applied for on-site sewage disposal. Creation of impervious surfaces is
minimized to the greatest extent feasible in order to limit the need for
stormwater management systems, and all facilities are designed and
constructed using best management practices to limit and avoid resource
impacts. Federal, state and local permit and regulatory requirements are
addressed during facility development. This includes the design of all new park
facilities consistent with the universal access requirements of the Americans
with Disabilities Act (ADA). After new facilities are constructed, park staff
monitors conditions to ensure that impacts remain within acceptable levels.
Potential Uses
Public Access and Recreational Opportunities
Goal: Provide public access and recreational opportunities in the park.
The existing recreational activities and programs of this state park are
appropriate to the natural and cultural resources contained in the park and
should be continued. New and improved activities and programs are also
recommended and discussed below.
87
Objective: Maintain the park’s current access points and recreational
uses.
Resource-based recreation activities including beach access, picnicking,
paddling, and interpretation of natural and cultural resources are the most
popular activities at the park that accommodates visitors with a range of
interests. Aside from what visitor’s experience on their own or in small groups,
there is also an impressive offering of regularly scheduled interpretive programs
largely supported by the park’s Citizen Support Organization (CSO). Daily
nature walks, birding programs, butterfly tours, and snorkeling education are
just a few of the opportunities readily available at the park. Several relatively
simple renovations around the park are proposed for the next ten years. These
enhancements to existing facilities such as improved walkways to the beach will
serve to better the visitor experience.
Objective: Continue to provide the current repertoire of interpretive,
educational and recreational programs on a regular basis.
The park provides ample opportunities for interpretation and education on the
park’s natural and cultural resources as well as recreational programs. The
CSO, Friends of MacArthur Beach State Park is a particularly active group of
dedicated volunteers that are critical to providing many of these programs. On-
going programs offered through the CSO include nature walks, tours on the
park’s bird species and butterfly species, talks at the nature center on marine
animals and snakes, a course for paddling beginners, bi-monthly bluegrass
concerts, monthly car shows, and yearly nature scrape events.
In 2011, the Pew Family Natural Science Education Center opened in the park
to help promote natural science education and research. Serving both visitors
and staff, this nature center includes a classroom for students to have a chance
to dive deeper into their park discoveries, a research library to further the
center’s educational component, a discovery lab so that staff can nurture
animals, and an education gallery for viewing of interpretive displays.
These programs along with the nature center equip visitors with a better
understanding of their natural surroundings, the protection they require, and
how they can be better stewards of the land. The park will continue to work
collaboratively with their CSO in providing these programs over the coming 10
years.
88
Objective: Develop 1 new educational program.
The Friends of MacArthur Beach State Park have been working diligently with
the park to create a Citizen Science Marine Debris Program. The CSO is also
working in conjunction with The Community Foundation for Palm Beach and
Martin Counties. This program will invite visitors and the surrounding
community to participate in fighting against marine debris. This program
centers around offering an outlet for those who wish to take action in making
their environments more sustainable. The work of volunteers to remove marine
debris and the collection of data by park staff will directly feed into the
academic efforts of those with the Solid Waste Authority and National Oceanic
Atmospheric Administration. In the initial rollout of the program so far, Citizen
Scientists have already collected 1,500 pounds of marine debris from the park’s
beach.
Proposed Facilities
Capital Facilities and Infrastructure
Goal: Develop and maintain the capital facilities and infrastructure
necessary to implement the recommendations of the management plan.
John D. MacArthur Beach State Park has and continues to provide exceptional
opportunities for recreation and education that are truly unique to the park
system. The development of the park has been considerate and appropriate to
the needs and trends of recreation and resource management. The following
proposals seek to enhance the current qualities of the park and improve upon
existing infrastructure for reasons including environmental sensitivity, evolving
recreation trends, creating truly accessible facilities, and a need to reinvest in
the park’s aging infrastructure.
The existing facilities of this state park are appropriate to the natural and
cultural resources contained in the park and should be maintained. New
construction, as discussed further below, is recommended to improve the
quality and safety of the recreational opportunities, to improve the protection of
park resources, and to streamline the efficiency of park operations. The
following is a summary of improved and new facilities needed to implement the
conceptual land use plan for John D. MacArthur Beach State Park
Objective: Maintain all public and support facilities in the park.
All capital facilities, trails and roads within the park will be kept in proper
condition through the daily or regular work of park staff and/or contracted help.
89
Objective: Improve/repair 8 existing facilities and 0.3 miles of trail
Major repair projects for park facilities may be accomplished within the ten-year
term of this management plan, if funding is made available. These include the
modification of existing park facilities to bring them into compliance with the
Americans with Disabilities Act (a top priority for all facilities maintained by
DRP). The following discussion of other recommended improvements and
repairs are organized by use area within the park.
A1A Park Entrance
The park’s entrance off A1A follows along a quiet portion of this road
surrounded on both sides by lush hammock and mangrove. The entrance serves
the park well but could be improved in terms of visibility. In its current state, it
is easy to miss the park entrance. Landscaping improvements or additional
signage to make the entrance more visible should be considered. The ranger
station at the entrance is in good condition, however the plumbing system
should be connected to the central sewer system of the county.
Satinleaf Picnic Area
This picnic area is a popular place for small events and casual gatherings. The
restrooms attached to the pavilion are in good condition but the frames and
doors to the restrooms should be replaced as well as the pavilion’s plumbing
should be connected to the central sewer system of the county.
Main Day Use Area
Majority of the park’s interpretation is based in the Lake Worth Day Use Area.
The area includes the Natural Science Education Center, paddling rentals,
pavilions, and trams to take people to and from the beach. The actual layout of
this area should be made more pedestrian friendly and provide for a better
sense of arrival. Specific improvements include adding crosswalk markings from
parking areas onto the path and boardwalk that lead to nature center and
adding wayfinding signage to easily orient visitors from the parking area to the
day use areas. Landscaping improvements should also be ongoing in the small
green spaces interwoven in the parking area. The pavilion in this area also
requires some updates including a new roof and a centralized line to the county
sewer system.
90
North Paddling Launch
The north paddling launch offers visitors access onto Lake Worth Cove just
north of the Main Day Use Area. The launch is in good condition but will be
made more accessible with the addition of a Mobi-mat. Due to its situation
among mangroves, the launch should also be stabilized with crushed shell to
facilitate easy access for visitors. An implementation plan should be in place
and carried out by park staff to control and monitor erosion at the launch site.
South Paddling Launch
This paddling launch currently provides visitors access onto Lake Worth Lagoon.
Paddling is a relatively popular activity at the park, but this could be further
capitalized on with a few improvements. Given that it is relatively separated
from other use areas of the park, the launch area currently lacks
accommodations like those offered throughout the rest of the park. This area
would benefit from the addition of potable water, electric, and a hookup to
sewer if possible. To enhance the access of this area, Mobi-mat should also be
added. The construction of a small concessionaire building adjacent to the
parking area could facilitate paddling vessel rentals and other small purchases
by visitors. The parking area would consist of 10 to 15 parking spots, and if
needed, further stabilized with gravel.
Munyon Island
The current visitor use of Munyon Island is relatively low compared to other
areas in the park. There is significant damage to the two main boardwalks on
the island and repair or complete replacement is required.
One of the main features of Munyon Island is a large dock structure which
contains prefabricated cribbing below the structure to keep it in place.
Observations indicate that the below riprap cribbing has resulted in an eddy
circulating in the area, the underlying cribbing has prevented a natural flow of
water and the constant circulating water as eroded parts of the shoreline. The
erosion of the shoreline has caused a loss of mangroves on the island.
Furtherer hydrological studies would need to be conducted in collaboration with
DRP and other DEP divisions to evaluate the on-going water flow and all future
options to address the issues. Possible solutions include beach nourishment
along the island to restore the shoreline, and removal or reduction of the
amount of cribbing. This removal will likely result in the cessation of the eddy
and allow the return of natural waterflow to the area.
The main walkway along the Intracoastal Waterway needs complete re-decking
simply due to age, and possibly due to the eddy and the ongoing erosion, the
underlying structural support has diminished. Additionally, the other boardwalk
91
that leads to the Island Trail needs to be assessed for structural support and
damage.
Additionally, the floating dock needs to be replaced as it incurred damages
throughout the years, and more recently from Hurricane Irma in 2017.
Other proposed additions to the facilities of Munyon Island include a paddling
rack, potable water line, and an observation deck overlooking the Intracoastal
Waterway, similar in style to observation platforms on the main boardwalk that
crosses Lake Worth Lagoon. The observation deck option would be contingent
on the restoration of the shoreline and replaced boardwalk. These new
improvements will better cater to existing and new user groups.
Atlantic Beach Access Area
This area refers to the beach access point as well as the connected Lagoon
Boardwalk that transports visitors from the foliage-filled entrance area to the
expansive beach views. The boardwalk itself is an impressive structure that
allows for a multitude of varied viewsheds and interpretive opportunities. To
maintain the high volume of visitors utilizing this access, the boardwalk requires
the addition of structural support beams and re-decking for the entire
boardwalk, as needed.
The restroom facilities along this access require termite treatment, and the
extent of damaged assessed prior to treatment may require a full replacement
of the restrooms. In the case that the termites can be successfully treated
without full replacement of the restrooms, the facilities will also need to be
freshly painted and all the interior fixtures replaced including new floor drains.
To increase accessibility to the beach area, a Mobi-mat should be added near
the main dune crossover and only to be used during non-turtle nesting season
and removed from the beach prior to nesting season and reinstalled after
November 1st.
Like the work that has already been done on the Satinleaf Trail, the beach
access trails that run perpendicular to the boardwalk should be stabilized with
crushed shell.
Support Area
The parks 3-Bay shop needs total replacement. The current one has suffered
significant termite damage over the years. A new shop is to be constructed in
the existing footprint of the current one.
The other support facilities at the park are generally in good condition.
92
Objective: Construct 1 new facility
Volunteer Camping Area
The park has a very active CSO and volunteer base, and the addition of
volunteer sites in a disturbed area just to the west of the parking adjacent to
the Satinleaf Picnic Area will help to continue and enhance volunteerism in the
park. Hookups to utilities are already available for this site underneath the
hammock canopy. In the future, this site could also serve as an area for
employee owned trailer sites as well.
Facilities Development
Preliminary cost estimates for these recommended facilities and improvements
are provided in the Ten-Year Implementation Schedule and Cost Estimates
(Table 5) located in the Implementation Component of this plan. These cost
estimates are based on the most cost-effective construction standards available
at this time. The preliminary estimates are provided to assist DRP in budgeting
future park improvements and may be revised as more information is collected
through the planning and design processes. New facilities and improvements to
existing facilities recommended by the plan include:

Resiliency Planning
Specific effects of sea level rise at this park are not yet known, however,
general changes to the park’s natural and built landscapes are predictable.
Parkwide, the maritime hammock may potentially become increasingly wet such
that public and staff access along trails and management roads will be impeded.
Given the significance of access to this park’s resources, long term solutions to
wet or inundated sites may require installation of boardwalks and off-grade
buildings. The existing environmental education center is already designed as
off grade however, extensions of the off-grade structures may need to be
considered.
Paddling launches may require setbacks to adjust for rise in mean high water
and the extent of paddling access to submerged areas may increase.
At this stage in the resiliency planning process, no specific developments,
renovations, landscape alterations, or augmentations are proposed.
96
Visitor Use Management
The DRP manages visitor use to sustain the quality of park resources and the
visitor experience, consistent with the purposes of the park. The dynamic
nature of visitor use requires a deliberate and adaptive approach to managing
resource impacts from recreational activity.
To manage visitor use, the DRP will rely on a variety of management tools and
strategies, potentially including modes of access and limits on the number of
people within certain areas of the park. Achieving balance between resource
protection and public access is fundamental to the provision of resource-based
recreation and interpretation. The premise of a visitor use management
strategy is to protect the park’s significant natural and cultural resources. A
strategy may include site-specific indicators and thresholds selected to monitor
resource conditions and visitor experience. By monitoring conditions over time
and clearly documenting when conditions become problematic, the DRP can
implement actions to prevent unacceptable resource conditions.
Levels of visitation, patterns of recreational use, and varieties of available
recreational activities are routinely monitored parkwide. Indicators have shown
that this park is operating sustainably for its resources and offers high quality
experiences for its visitors.
Resource indicators to be considered during the next ten-year planning period
include:
o Erosion along trails through maritime hammock and other sensitive
natural communities
o Trampling of dune vegetation, formations, and wildlife landward of the
beach wrack line
o Deterioration of the worm reef or other significant submerged resources
along the park beach
o Erosion or disturbance of vegetation along the shorelines of Lake Worth
Lagoon and Munyon Island
Quality of visitor experience indicators to be considered during the next ten-
year planning period include:
o Congestion of day use areas by visitors at one time
o Insufficient visitor amenities to safely and comfortably support the
intended activities of a use area
o Obstruction of viewsheds through scenic areas of the park
o Interruption of serenity in areas intended for passive interpretive
experience
97
Thresholds are defined as the minimally acceptable conditions for each indicator
and represent the point at which resource impacts will require a change in
management strategy or actions to improve resource conditions. Thresholds are
assigned based on the desired resource conditions, the data on existing
conditions, relevant research studies, management experience, and current
visitor use patterns. It is important to note that identified thresholds still
represent acceptable resource conditions and not degraded or impaired
conditions. Management actions may also be taken prior to reaching the
thresholds.
Specific thresholds for resource conditions and experiential quality have not yet
been established for John D. MacArthur Beach State Park. As monitoring
continues, collected data may be used to determine baseline and desired
conditions, thereby establishing thresholds.
98
Optimum Boundary
The optimum boundary map reflects lands considered desirable for direct
management by the DRP as part of the state park. These parcels may include
public or privately-owned land that would improve the continuity of existing
parklands, provide the most efficient boundary configuration, improve access to
the park, provide additional natural and cultural resource protection or allow for
future expansion of recreational activities. Parklands that are potentially surplus
to the management needs of DRP are also identified. As additional needs are
identified through park use, development, and research, and as land use
changes on adjacent property, modification of the park’s optimum boundary
may be necessary.
Identification of parcels on the optimum boundary map is intended solely for
planning purposes. It is not to be used in connection with any regulatory
purposes. Any party or governmental entity should not use a property’s
identification on the optimum boundary map to reduce or restrict the lawful
rights of private landowners. Identification on the map does not empower or
suggest that any government entity should impose additional or more
restrictive environmental land use or zoning regulations. Identification should
not be used as the basis for permit denial or the imposition of permit
conditions.
The park is managed in accordance with all applicable laws and administrative
rules. The Board of Trustees leases park lands to the Division of Recreation and
Parks for the management, conservation and recreation. The Board of Trustees
has a separate agreement with the Division to manage aspects of the 400-foot
riparian zone from the edge of mean high-water line outward from the Board of
Trustees property boundary to all beaches, bays, estuarine areas, rivers or
streams. The 400-foot zone is interpreted to begin beyond emergent wetland
vegetation. The agreement is intended in part to provide additional protection
to resources of the park shorelines.
Currently, the park has a 400-foot management authority over the surrounding
submerged lands. The proposed optimum boundary for John D. MacArthur
Beach State Park will extend the park’s eastern boundary along the Atlantic
Ocean an additional 400 feet over submerged lands. This 400- foot wide area is
known to contain a significant amount of worm reef, especially on the north end
of the beach with smaller outcroppings found along the entire 1.8 mile stretch
of beach. These worm reefs aid in shoreline protection by reducing the overall
incoming wave energy.
99
Acquiring this area would maximize the DRP’s ability to monitor, protect, and
research marine resources, and optimally manage visitor activity in the water.
Management of this submerged area would also reinforce the park’s sea turtle
nesting and rescue program. Additional recreational and interpretive
opportunities in this acquired area would enhance the overall visitor experience.

IMPLEMENTATION COMPONENT
The resource management and land use components of this management plan
provide a thorough inventory of the park’s natural, cultural and recreational
resources. They outline the park’s management needs and problems and
recommend both short and long-term objectives and actions to meet those needs.
The implementation component addresses the administrative goal for the park and
reports on the Division of Recreation and Parks (DRP) progress toward achieving
resource management, operational and capital improvement goals and objectives
since approval of the previous management plan for this park. This component also
compiles the management goals, objectives and actions expressed in the separate
parts of this management plan for easy review. Estimated costs for the ten-year
period of this plan are provided for each action and objective, and the costs are
summarized under standard categories of land management activities.
MANAGEMENT PROGRESS
Since the approval of the last management plan for John D. MacArthur Beach State
Park in 2005, significant work has been accomplished and progress made towards
meeting the DRP’s management objectives for the park. These accomplishments fall
within three of the five general categories that encompass the mission of the park
and the DRP.

loggerhead and green turtles is used to help formulate state and federal
policies for the management of these imperiled marine turtles. The park has
been conducting daily marine turtle nest surveys since 1982.
•The Park Service implemented a predator control and monitoring program at
the park that removes predators of marine turtle nests from the nesting
beach. Historically, up to 95% of turtle nests were lost to predation. Because
of the predator removal program, predation levels on marine turtle nests
have been reduced to levels of less than 5%.
•A Citizen Science program was established at the park to assist staff with
collecting important data from ongoing monitoring and research programs.
Currently, the citizen scientists (volunteers) are conducting nest excavations
to determine nest productivity of imperiled marine turtles. This data will be
used to measure the number of hatchlings that are produced at the park.
•Fish population censuring is conducted annually in conjunction with the Great
Annual Fish Count. The Florida Park Service partners with other agencies and
volunteers to gather data on fish species and abundance.
•Lionfish eradication is a part of the invasive exotic control program at the
park since the fish was first observed in park waters in 2012. DRP staff
conduct lionfish surveys on a regular basis. All lionfish are removed under
protocols established by FFWCC. Due to these efforts, population is under
control and new sightings are rare.
•In 2010 a seagrass monitoring program was implemented to gather baseline
data on the estuarine seagrass community of the park including species
diversity, species abundance, health and changes over time. Biannual
104
surveys are conducted in the Lake Worth Cove to capture the growing
season. This program was established in partnership with Palm Beach
Atlantic University research professor Dr. Tom Chesnes.
•A seagrass monitoring program implemented at the park revealed that all 7
species of seagrass found in Florida are growing in Lake Worth Cove.
Included are several large areas of the federally listed species Johnson’s
seagrass (Halophila johnsonii) and Widgeon grass (Ruppia maritima). The
park is the only known place in the entire Lake Worth Lagoon where this
species is known to grow.
•A research project to determine the bat species utilizing the park was
conducted by research professor Dr. Maurice Thomas of Palm Beach Atlantic
University. Mist nets were placed throughout the park which yielded two new
bat species.
•A Munyon Island Internal Combustion Exclusion Zone was established in
2010. The zone protects sensitive seagrass beds east of Munyon Island by
restricting boat traffic to non-combustion propulsion only. These seagrass
beds provide food and shelter to commercial and recreational marine species
as well as juvenile imperiled green marine turtles.
•Palm Beach County Environmental Resource Management (ERM) conducted a
catch and release project of marine turtles in the Lake Worth Lagoon. The
northern section of the Lagoon, much of which is located within the
boundaries of the park, functions as important developmental habitat for
juvenile green marine turtles. A related project by ERM in the nearshore
ocean habitats showed significantly more marine turtles in park waters then
the surrounding areas.
•Additional research projects were conducted by students at Palm Beach
Atlantic University, Broward College and Florida Atlantic University. All the
projects contributed to the species inventories and increased the number of
species known to occur in the park. These projects include the following:
a. Research the species composition of drift algae found in Lake Worth
Cove. Varying size mats of drift algae are observed in the estuarine
seagrass beds where they tumble and sometimes gather in natural
depressions.
b.The biodiversity of mollusks found in the seagrass beds in the Lake
Worth Cove.
c.Determine if red mangroves, Rhizophora mangle, that are stressed
from being cut and maintained at 1.8 meters allow more isopods,
Sphaeroma terebrans, to bore into the prop roots thus weakening the
mangrove.
d.Determine species of reptiles found within the Park by setting up a
pitfall array herpetology study in management zone 2.
e.Recording the coordinates of all known specimens of rosary pea,
bowstring hemp and dragon fruit cactus on Munyon Island.
105
f.Recording the coordinates of all known specimens of the invasive
exotic species, Santa Maria tree, Callophyllum antollanum within the
Park boundaries.
g.Determining factors that affect oyster spat recruitment.
h.Surveying oyster distribution and health in the Park’s estuary.
•Park staff and volunteers has recorded the coordinates of all known
specimens of sea lavender, Argusia gnaphalodes, and burrowing four o’clock,
Okenia hypogaea, in the park. This information will be used to implement a
monitoring program that will track changes to the plants’ health and size over
time.
•District biologists and park staff perform periodic removal and treatment of
invasive plants in the park. Cooperative workdays with staff biologists from
other agencies are also used to periodically remove and treat invasive plants.
•District biologists routinely seek additional funding to remove larger areas of
invasive exotics. Several large projects include the following:
1.2006: contractor project funded by DEPs Bureau of Invasive Plant
Management to remove 5.5 acres of heavily infested Brazilian pepper in
the maritime hammock.
2.2007: contractor project funded by the Division of Rec and Parks to
treat 60 acres of maritime hammock. Species that were treated
included Brazilian pepper, java plum, bishopwood, umbrellas tree,
carrotwood, Surinam cherry and areca palm.
3.2009: contractor project funded by the Division of Recreation and Parks
to treat 13 acres in the hammock/strand ecotone from the top of the
dune line west to the mangrove edge. Species that were treated
include Brazilian pepper, beach naupaka, carrotwood, bowstring hemp,
rosary pea and Portia tree.
4.2013: contractor project funded by the Division of Recreation and Parks
to treat 12.7 acres in the hammock/strand ecotone from the top of the
dune line west to the mangrove edge. Species that were treated
include Brazilian pepper, beach naupaka, carrotwood.
5.2017: contractor project funded by the Division of Recreation and Parks
to treat 35 acres in the maritime hammock. Species that were treated
include Brazilian pepper, carrotwood, bishopwood, schefflera, rosary
pea, bowstring hemp and various exotic palms.
6.2018/2019: contractor project funded by the Division of Recreation and
Parks to treat 80 acres in the maritime hammock and on Munyon
Island. Species that were treated include Brazilian pepper, carrotwood,
winged yam, Australian pine, rosary pea, balsampear, areca palm,
oyster plant, bowstring hemp.
•Friends secured Exotic Removal grant, $10,000 annually for 3 years
1.Independent Contractors assisted PSS in removal
2.Purchase of an all-terrain vehicle for exotic removal
3.Building new shade house for the growth of replacement plants
106
•The new Citizen Science Marine Debris Program was created for all Park
visitors to participate in. A Citizen Science Marine Debris Program Area was
installed where visitors can learn and then participate in the program by
collecting marine debris from the beach and then weigh/report how much
was collected. This information is being reported to several agencies.
•Summer Camp students have been participating in a Citizen Science Program
with REEF Fish Counts since 2012. Data can used by researchers/scientists to
see trends of fish populations based on summer camper citizen scientist
observations and data input.
Cultural Resources
•Plant native vegetation to promote dune formation and reduce the threat of
erosion.
•Remove and treat exotic plants in and around archeological sites to prevent
damage from vegetative growth.
Recreation and Visitor Services
•The Munyon Island Public Boat Docking Facility was opened to the public in
2011. The facility is designed to accommodate 20 boats for day-use mooring
and access to Munyon Island trails, beaches, and picnic pavilions.
•An interpretive kiosk has been placed on Munyon Island explaining the
island’s rich cultural history. The kiosk also points out the various partners
involved in the island’s restoration.
•As a result of a local Boy Scout’s Eagle Scout project, a set of stairs has been
installed to better enable kayakers to access Munyon Island near the existing
boardwalk.
•The park’s existing Nature Center, which also housed the Friends of
MacArthur Beach gift shop, has been completely renovated. The new
interpretive displays incorporate many tactile and interactive features to
better engage visitors.
•A new 1500-gallon central aquarium depicting the park’s estuary simulates
natural habitat of the mangrove shoreline for many aquatic species
•The center’s existing reef and sea turtle tanks were removed and refurbished
to provide a better visitor experience and to better reflect the park’s habitats.
•The gift shop was moved to a new location making room for a Welcome
Center and cultural history interpretive displays.
107
•The park’s Natural Science Education Program now provides both classroom
and field experiences to over 5000 Palm Beach County students per school
year with 71% of students attending Title 1 schools. The program meets all
requirements for the Next Generation Sunshine State Standards (NGSSS) for
science as set forth by the Florida State Board of Education which includes
Making Stem Connections.
•MacBeach Explorations - Each year since 2001, up to 20 Title I teachers
within a 25 mile radius are part of a grant,– bringing them into a 3-5 day
training workshop over the summer, certifying them in Project Learning Tree
and Project WILD; the teachers then get to bring their students back to the
Park in the academic year for an extended Field Experience.
•Students throughout the county and beyond were able to take advantage of
monthly Vodcasts (Video on Demand) in which students and teachers can
interact from their classrooms with park and education staff. Vodcast
participation for each academic year is approximately 10,000 students each
academic year.
•Summer Science Camp is offered in 6, one-week sessions, all-day
experiences for campers. The different groups participate and learn in age-
appropriate activities: Sunshine Explorers, ages 6-8; Junior Rangers, ages 9-
10; Marine Biologists, ages 11-14; and Marine Champions, ages 12-14.
There is also a Counselor-In-Training program which students 15-17 can
assist with programing.
•Junior Friends of MacArthur Beach State Park is a volunteer group that
performs community service projects for the Park. Middle and High school
aged students participate in Citizen Science projects, beach re-nourishments
plantings, exotic plant removals, and beach/mangrove cleanups etc.
•Summer camp is now offered to 3 age groups and has been expanded to an
all-day experience for campers.
•The park continues to develop new programming. The more recent additions
include a Butterfly Walk, Introduction to Surfing, Introduction to Snorkeling,
Introduction to Kayaking, Live Snake Talks, Weekly Fish Feeding, Birding by
Kayak, Reef Program, Monthly Beach Cleanups, Citizen Science Programs,
Moonlight Concert Series, and a Guest Speaker Series.
•An emergency response UTV has been built to provide access to the beach in
emergency situations when park visitors or staff are in need.
•An emergency access has been built in place of a dune crossover to provide
quick access to the beach in emergency situations,
108
Park Facilities
•As part of a $2.1 million Partnership in Parks (PIP) project, the Friends of
MacArthur Beach provided funding and support for renovation of the existing
Nature Center and construction of a new Education Center Complex; The Pew
Family Natural Science Education Center.
•A new state of the art theater system replaced the existing system. The new
system enables visitors to select from a variety of videos focusing on the
park and the area’s natural resources.
•The Education Center Complex was opened to the public in 2012. The facility
contains a state-of-the-art classroom, staff lab, library, offices, and the
Friend’s-operated gift shop. A new1200 gallon educational sea turtle tank has
also been installed on the front deck of the facility.
MANAGEMENT PLAN IMPLEMENTATION
This management plan is written for a timeframe of ten years, as required by
Section 253.034 Florida Statutes. The Ten-Year Implementation Schedule and Cost
Estimates (Table 5) summarizes the management goals, objectives and actions
that are recommended for implementation over this period, and beyond. Measures
are identified for assessing progress toward completing each objective and action.
A time frame for completing each objective and action is provided. Preliminary cost
estimates for each action are provided and the estimated total costs to complete
each objective are computed. Finally, all costs are consolidated under the following
five standard land management categories: Resource Management, Administration
and Support, Capital Improvements, Recreation Visitor Services and Law
Enforcement.
Many of the actions identified in the plan can be implemented using existing staff
and funding. However, a number of continuing activities and new activities with
measurable quantity targets and projected completion dates are identified that
cannot be completed during the life of this plan unless additional resources for
these purposes are provided. The plan’s recommended actions, time frames and
cost estimates will guide the DRP’s planning and budgeting activities over the
period of this plan. It must be noted that these recommendations are based on the
information that exists at the time the plan was prepared. A high degree of
adaptability and flexibility must be built into this process to ensure that the DRP can
adjust to changes in the availability of funds, improved understanding of the park’s
natural and cultural resources, and changes in statewide land management issues,
priorities and policies.
Statewide priorities for all aspects of land management are evaluated each year as
part of the process for developing the DRP’s annual legislative budget requests.
When preparing these annual requests, the DRP considers the needs and priorities
of the entire state park system and the projected availability of funding from all
sources during the upcoming fiscal year. In addition to annual legislative
109
appropriations, the DRP pursues supplemental sources of funds and staff resources
wherever possible, including grants, volunteers and partnerships with other entities.
The DRP’s ability to accomplish the specific actions identified in the plan will be
determined largely by the availability of funds and staff for these purposes, which
may vary from year to year. Consequently, the target schedules and estimated
costs identified in Table 5 may need to be adjusted during the ten-year
management planning cycle.

Advisory Group Members and Report
The Advisory Group meeting to review the proposed unit management plan (UMP)
for John D. MacArthur Beach State Park was held in North Palm Beach, FL at John
D.MacArthur Beach State Park in the park’s Nature Education Center on Tuesday
February 26th, 2020 at 9:00 AM.
Appointed members unable to attend include: Mayor Darryl Aubrey, Commissioner Hal R.
Valeche, Chauncey Goss, Laura Bloom, Lieutenant Austin Warne, Richard Zambrano, Winnie
Said, Jason Love, Jason O’Donoughue, Ryan Wheler and George Luer.
Attending Division of Recreation and Parks (DRP) staff members from the park,
district office and the Office of Park Planning were Kevin Jones, Brian Addison,
David Dearth, Jacob Bennett, Ernest Cowan, Tyler Maldonando and Yasmine
Armaghani.
Ms. Armaghani began the meeting by explaining the purpose of the advisory group
and thanking the advisory group members for their time and participation in the
meeting. Ms. Armaghani then asked each member of the advisory group to express their
comments on the draft management plan. After all the comments were shared, Ms.
Armaghani described the next steps for drafting the plan and then the meeting was
adjourned.
Summary of Advisory Group Comments____________________________
Cheryl Houghtelin (Executive Director, Friends of John D. MacArthur Beach
State Park) commented and inquired about the optimum boundary map in the unit
management plan and asked who currently has management authority of that 400-foot
strip. Additional questions regarding the optimum boundary included: who would give us
(the park) that property, and how the park acquires it.
Ernest Cowan explained that the park system currently has a 400-foot management
authority of submerged lands of the 400-foot area, he further explained that, the optimum
boundary proposed would just extend the current boundary of the park to include that area.
Mr. Maldonado added, that that the Division of State Lands in the DEP who hold sovereign
submerged land leases, would amend the 400-foot area to the park boundary. Kevin Jones
also noted that there is no monetary exchange when adding this land to the park boundary.
Brian Addison also added that having the proposed 400-foot area in the park boundary
would allow the park to apply the park rules of 62d to that area.
Tim Hullihan (Friends of John D. MacArthur Beach State Park) started off by
discussing the presence of the Curly tailed lizard at the park and general area. Mr. Hullihan
asked if anything will be done regarding its removal. Continued with expressing concern
about the lizard since it is considered an exotic species and it is driving out the native
species located at the park and surrounding area, and how it is taking away food sources
from the native lizard species and other animals. Mr. Hullihan also recommended that
information regarding the Curly tailed lizard be added to the resource management
component to the unit management plan and plans for controlling the populations be
discussed as currently there is no information on in the UMP. Mr. Cowan then responded
saying that he will make edits to include information regarding the Curly tailed lizard.
Additionally, he suggested that the proposed “volunteer sites” be designed in a more
sustainable way, instead of trailer sites the “volunteer site” should be more “carbon
negative” instead of allowing people to bring their automobiles (RVs), we have solar based
cabins installed.

Additionally, Mr. Hullihan provided comments via email saying:
“I thought of one more comment. I have raised it before with David Dearth, so I
forgot about it until now. It is actually really simple to implement, and important to safety
for walkers and bikers in the park. Essential, there is nothing that delineates pedestrian /
biker lanes from vehicle lanes. Even at 15 MPH, I have had close encounters with
pedestrianism and bikers on our main drive because there are curves and blind spots. At 15
MPH, a car only needs 9-feet of roadway width, per FDOT “community design standards,” so
it would be easy to add a 3-foot wide designated bike and pedestrian lane so conflicts can
be reduced. Also (I guess this is a second comment), all state parks charge more for 4
walkers or bikers to enter a park (8-dollars), than 4 people in a car (5-dollars). That is a
reverse incentive, or disincentive, to using non-polluting transportation to arrive at a state
park. Seems a little out of date in my view.”
*end of email comments*
Momoka Maeda (Florida Fish & Wildlife) – During initial introductions of the advisory
group present at the meeting, Ms. Madeo stated that she is representing Ricardo Zambrano,
Regional Biologist for Florida Fish & Wildlife Commission.
Ms. Madea commented on the monitoring protocols for some of the species including the
wading bird species that are considered state threatened and that more monitoring should
be done, possibly conduct quarterly monitoring, especially for species such as the Blue
heron and moving them up from Tier 1 to Tier 2. They also want to encourage continued
winter shore bird surveys, especially for the Winter culver. Ms. Madea inquired about recent
small mammal surveys done in the tropical hardwood hammock at the park. Mr. Cowan
responded that no surveys have been done in that are for the past 10 years. She also
inquired about any recent surveys about the gopher tortoises and their known locations at
the park. Mr. Dearth then referenced Management Zones map to showing the group where
in the park the gopher tortoises have been found.
Clive Pinnock (Audubon Society of The Everglades) – commented on his recent
participation with a shorebird survey, with The Audubon Society. Mr. Pinnock inquired about
breeding bird surveys in the tropical hammock, if there were any conduct recently and how
frequently they are done. Mr. Cowan then responded to Mr. Pinnock saying if any surveys
regarding the breeding birds are done, they are anecdotal. Mr. Jones than added that they
would like to partner with other agencies to do the surveys, like Audubon.
Stephanie Pew (Local Resident) expressed concern about the continued erosion at
Munyon Island, what was being done regarding the future of the island, and the presence of
the dock itself. Mrs. Pew also asked about the proposed developments at the park, and
which projects are top priority, and how that is determined and funded.
Kevin Jones responded to Mrs. Pew’s question saying that the district is aware of the issue,
Mr. Dearth then added once a hydrological study is done, DRP can address the dock and
what will be done with it.
Vice Mayor Mark Mullinix (Village of Palm Beach) – Mr. Mullinix inquired about the
Iguanas at the park and what was being done regarding their removal and the removal of
Curly tailed lizard. Mr. Cowan said the current method is trapping them and is the most
humanize way. Mr. Cowan also added saying that the Iguanas are currently are in a
“maintenance level”. Mr. Mullinix then commented saying he would rather see money
dedicated on items such land acquisition, resource protection, park management instead of
“maintaining” the current population of the invasive.

John D. MacArthur Beach State Park
Advisory Group Members and Report
Robert Cochrane & Hennery Calway (Anthropological Society of Palm Beach)-
Expressed comments about the historic and prehistoric sites at the park. Their main area of
concern is the “Singer Island Midden” with regards to the extensive erosion over the years.
Mr. Cochrane commented on how they would like to see preservation of the site and
mitigation if they site will be impacted in anyway, like covering the area with sand or
general vegetation, like called for out in the plan. To Access the resources, “as archeologist
we don’t want to dig”. Mr.Calway talked about technological advances that rabidly changes
over the year. The priority should be preservation instead of investigation, and they
encourage vegetation shielding around archeological sites.
Bob Hamilton (Palm Beach County Parks & Recreation) commented on the “Resiliency
Planning” section of the draft unit management plan and suggested that any future
regarding resiliency at the park and any changes that would be done be written in the
current plan. Mr. Hamilton also suggested that the Park Service fast track some ideas for
the park regarding sea level, he also added that his parks within in the county are dealing
with flooding currently, from King Tide etc. and are adapting currently with infrastructure
changes at several of the county parks such as raising their boat ramps a foot a half.
Gary Ward (Long Time Resident & Business Owner) –
Provided comments via email and in person:
Email Comments: As preamble to my attached observations and comments we reiterate the
discussions we have had with you, your administrative assistant and the Park Manager as to
notice and reverse scheduling of the Advisory Group Meeting. The notice I received via Email
was issued the afternoon of 20 February 2020, 5 days 19 hours before your first scheduled
meeting. The Advisory Group Meeting was scheduled the morning of the Public Meeting in the
late afternoon early evening of the same day. The notice was inadequate for the public and
without question scheduling the Advisory Group Meeting prior to the Public Meeting defeated
one of the prime purposes of having the supposed knowledgeable locally situated folk opine on
what they would have normally heard from the public. As a result, after you redraft the Plan it
would appear mandated that the meetings need to be re-accomplished. The excuse that agency
employee travel from Tallahassee was facilitated totally fails in as much as the meetings are first
for public input and not the supposed convenience of Tallahassee agency employees
The composition of the Advisory Group was not as diverse as previous review groups.
Particularly absent were the adjacent neighbors particularly the Catholic Church to the north
and the condo commandos / single family homeowners to the south plus the commercial
recreational activity vendors vicinity Riviera Beach and Lake Park. The highest level of
government the Village of North Palm Beach did attend (although late) with three folk and they
should be consulted during your first rewrite of the DRAFT plan.

DRAFT (February 14, 2020– 1251 pm) UNIT MANAGEMENT UPDATE PLAN
WARD INITIAL OBSERVATIONS AND COMMENTS
11 March 2020
Number of pages of the DRAFT is grossly excessive! The current plan is 116 and this DRAFT
is 176. The Current Unit Management Plan also includes an extra nine pages of competent
oversight review by the Division of State Lands Staff Team Review pursuant to 259.036 F.S. As
discussed with you a concerted effort needs to be made to significantly reduce the number of
pages to make the document more readable and significantly more usable by staff and the public.

Regarding a Team review, I forgot to query at the meetings why that statutorily required action
report and was not included in the DRAFT plan?? It should be and its accomplishment is a
major element of making State of Florida Parks impressive and top ranked.
Although a list of the Advisory Committee Members was provided by the Office within two hours,
its tentative nature was emphasized the afternoon of 20 February 2020 again indicating the lack
of thought in obtain a comprehensive review group.
This DRAFT plan (the fourth) is late like the last with a decade and half interval, rather than the
10-year revision cycle expected. We have visited the Park Planning Office at least four times in
the last half decade and more times via telephone inquiring about this update.
Again, given the sparse attendance at the meetings (most likely notice related) a redo of the
public input is expected to achieve compliance with the established Department Planning
Process. (See: https://floridadep.gov/sites/default/files/PlanningProcess_0.pdf)
We do expect timely notice of future Office of Park Planning meetings plus the ARC meeting
whether in Lakeland in August or Tallahassee in October or December.

WARD INITIAL OBSERVATIONS AND COMMENTS – 11 March 2020
DRAFT 105 Pages of text Compared to 34 Pages for 2005 Unit Management Plan
The two meetings held 26 February 2020 raised a number of topics, however my take was that
issues of 1) maintenance, 2) volunteer & research facilities, 3) water quality, 4) increased
vendor/concessionaire operations, 5) exotics (plant and animal) control, 6) clothing optional
beaches, 7) Big Munyon Island issues of boat facilities, so-called erosion and primitive young
folk camping sites (concessionaire), 8) outreach to adjacent high- density communities to
increase attendance were prime. As noted elsewhere the backwards meetings should require a
second round of meetings for this update plan to flesh out these issues prior to the Acquisition
and Restoration Council submission.
John D. MacArthur Beach State Park
Advisory Group Members and Report
The existing Unit Management Plan (April 22, 2005) is certainly more concise and to the point
of educating State employees as well as the public, both users and neighboring citizens. To
achieve conciseness as well as comprehension take the existing Unit Management Plan and
compare it to the DRAFT to see what languages are better.
INTRODUCTION
As one example of degradation of the new text take page 5 (3rd or middle paragraph) of the
existing Plan and Page 9 (bottom paragraph) of the new DRAFT.
The important change is changing “policy” to “internal direction” in the first sentence!! This is
an unacceptable wording change!! Then the new DRAFT uses only the acronym “OM” in the
second sentence creating a reader’s question as to what is “OM”. Acronyms should be kept to a
bare minimum in all the Unit Management Plan.
The first eight pages of the existing Unit Management Plan set high expectations whereas the
DRAFT is much more “feel good” rather than high guidance!
RESOURCE MANAGEMENT COMPONENT
Again, conciseness is desired. Re-review and insert specifics regarding earlier period cultural
resources evaluation (remember this is the only State Park in Palm Beach County and certainly
the only regulated area that has not been extensively land modified). The Park is one of the few
South Florida coastal previously inhabited areas by native Americans that has not suffered
reconstruction since European man arrived circa the 1500s. You did attempt to have “Ryan J.
Wheeler” as a member of the Advisory Group. He is an expert in the area and should be
searched out to contribute his recommendations for further research of the earlier Glades period
inhabitants. For visuals (pictures are always easy) you should research the Historical Society
of Palm Beach County, 300 North Dixie Highway, West Palm Beach, Florida 561/832-4165
which has a series of oblique aerials circa 1920 about the time the second inlet was being
constructed more fully converting Lake Worth to saline waters after hundreds, if not thousands
of years.

DRAFT 105 Pages of text Compared to 34 Pages for 2005 Unit Management Plan
After consultation with experts, under Cultural Resources, a sentence needs to be included that
adds facilitation of investigations as to potential early native American “transportation” works
from the Lake (and agricultural areas east side) to the Atlantic Ocean beach.
Hydrological Management or in other terms Water Quality Concerns. Since initial park design
in 1977 Surface Water Quality has been notable in areawide actions. Initial Beachside
sanitation always envisioned individual daily needs would be accommodated without discharge
pollution. Likewise, “pack-in, pack-out” was established for solid waste additives. (Today the
lack of vendor sales on the beachside is an extension of that philosophy!) What has been since
A 2 - 6
John D. MacArthur Beach State Park
Advisory Group Members and Report
the 1980s, is the attempt to enhance and expand the use of State Water Quality Standards (which
evolve from the federal Water Pollution Control Acts as amended of 1967. State Park waters
are classified as Outstanding Florida Waters in Florida’s system of requiring highest water
quality protection for any permitting or use. As poorly described in the middle paragraph on
DRAFT Page 67 all parks adjacent sovereignty submerged lands/waters have a rule adopted 400
zone for protection.
Coastal Beach Management in prior Plans the use of the 400-foot-wide nearshore zone has
been a factor in restricting solicitation of “beach fill or nourishment” projects to address
natural events often so-called “erosion”. A continued restriction of such beach fill projects is
warranted.
Arthropod Control Plans have been implemented in conjunction with various Chapter 388
Florida Statutes Mosquito Control Districts throughout the State and such Park
Planning/Operations should continue restrictions at MacArthur Park During the meetings the
issue of Green Iguanas was raised. Fish and Wildlife Conservation Commission is the operative
agency dealing with that species and should be involved.
As interim solution, the Park needs to have readily implementable action plans for predicted
“cold” events which result in the Green Iguana being immobilized or dying.
As a longer-term solution other county are considering have additional authorities granted the
established taxing Mosquito Control District to also address Green Iguanas as they and
development eliminate the need for arthropod control.

DRAFT 105 Pages of text Compared to 34 Pages for 2005 Unit Management Plan
LAND USE COMPONENT
Addressing only the significant issues, but reiterating that conciseness needs to be applied in all
this section text.
The first is 1) Maintenance—Even if the required frequency is only decades apart the plan needs
to emphasize a yearly “budget” request is needed and a “multi-year” PLAN also needs to be
provided from onsite park staff. Park maintenance is certainly above average for State Parks,
but, as always “nickel-dime” work needs to be routinely on the schedule. MacArthur Park’s
biggest job has always been vegetative (exotics removal) maintenance because of the large area
of cut-over farm fields of the late 1800s. Staff at the meetings exuded what success has been
accomplished because of exceeding the yearly goals of “treatment”.
A 2 - 7
John D. MacArthur Beach State Park
Advisory Group Members and Report
2)Volunteer & Research Facilities—Without question, the concept of RV type units for
transient research “interns” is a great use of public resources to enable housing for researchers
in an area of Florida with extremely high lodging rates.
4) Increased Vendor/Concessionaire Operations—The contemplated south re-opening of the
westside State Road A1A water recreational facility is well warranted. Adequate access and
parking (including the State Road R/W) can be accommodated. Increased variety of rentals is
warranted
6)Clothing Optional Beach Area—Given the diversity of the State such will happen. A late
arriving attendee (Shirley Mason of B.E.A.C.H.E.S.) impressed me as one of the most
knowledgeable persons at a “public input” meeting almost ever, certainly at Unit Management
Plan meetings!! Mr. MacArthur in his design conditions for the Park (like most Developers)
was somewhat specific. His son Rod was a major fan of clothing-optional (this century term)
beaches. As such the plans reflected substantial ground level parking east of State Road A1A on
the old pineapple farm fields. The trestle structure to the beach was directed to the southeast in
order to accomplish three ideals.
A)Provide a potential walking circulation system to serve the high density (75 du/ac originally
with unlimited building heights, now 20 du/ac with typically 200 feet heights although this
century variances have been obtained for 300 feet). residents of Riviera Beach. In other words,
make the beach terminus closer to the south end of the Atlantic frontage.

B)Leave the extreme north end with a potential for the Catholic Church to have a “beach
facility and keep away from the high rent Lost Tree Subdivision at the north boundary.
C) Provide for a future or soon long extent of dune and beachfront for now so-called “clothing
optional” beach.)
Having been born in this State in Orlando six months before the War, I do not foresee certain
changes in Government Services, however B.E.A.C.H.E.S. does have a long and successful track
record in Miami-Dade County including Haulover Park, so Mr. MacArthur must have been
pleased with Ms. Mason’s attendance at the Public Input meeting.
7)Big Munyon Island Boat Facilities/So-called Erosion/Primitive Young Person Camping
(concessionaire)– Regardless of allegations about extensive design of either the boating
facilities or the creation project of interior water channels (no-see-um habitat), such did not
occur! Modifications to Munyon Island west shore by various coastal engineering means is an
extremely poor use of capital or maintenance funds of the State or other governments.
A 2 - 8
John D. MacArthur Beach State Park
Advisory Group Members and Report
What is a needed effort is to provide young folk overnight supervised camping in urban areas to
close-in islands or other without facilities’ areas? Add a sentence to indicate under a
concessionaire begin actions to facilitate such activity.
8)Outreach Activities to Adjacent High-Density communities to increase Park Attendance –
The Park has increased this Century its attendance by nearly 50 percent, but no where reached
its capacities. First, add a yearly chart of Park Attendance. Such is a ready tool for getting
higher in attendance. Second, continue the “events” such a music and “food trucks. Third,
establish an “information” coordinator within the park (maybe volunteer) to increase notoriety.
Optimum Boundary -- Although, the issue of the 400 feet zone on the Atlantic Ocean frontage
should not have been an issue, having State Lands Division modify the Trustees Lease to include
such 400 feet is not a big deal. What is, is the addition of the early last century Trustees
submerged and uplands deed to sovereignty submerged lands west of State Road A1A in Riviera
Beach. Such is discussed on Pages A 7-22 and A 7-23 of the existing Unit Management Plan.
We will look forward to reviewing your revisions and an additional Public Input Meeting.

*end of email comments*
Jeremy Hubscah (Village of North Palm Beach) – spoke regarding water quality in Lake
Worth Lagoon. He then asked if we (the park service had an additional comment regarding
water quality). Mr. Cowan stated that the park service has participated in local initiatives
and sampling within the lagoon but not extensivity, but that it is called out for more testing
and monitoring. Mr. Hubscach then asked if that is a matter of additional funding from the
state to do more testing and monitoring. Mr. Cowan added that recent testing has been
done in house and with the local palm beach county and local university.
Summary of Written Comments from Advisory Group Members_______________
Mr. O’Donoughue (Division of Historical Resources) overall was satisfied with how the plans
addressed the cultural resources of the park. Mr. O’ Donoughue did note a few discrepancies
in the text that would need to be corrected.
Mr. Love (Florida Forest Service) suggested including the acreage number with the
description of each natural community in the Resource Management Component.
Staff Recommendations_________________________________________
•Additional language will be added to the Resource Management Component
regarding the Curly tailed lizard.

Notes on Composition of the Advisory Group________________________
Florida Statutes Chapter 259.032 Paragraph 10(b) establishes a requirement that all
state land management plans for properties greater than 160 acres will be reviewed by an
advisory group:
“Individual management plans required by s. 253.034(5), for parcels over 160 acres,
shall be developed with input from an advisory group. Members of this advisory group shall
include, at a minimum, representatives of the lead land managing agency, co-managing
entities, local private property owners, the appropriate soil and water conservation district,
a local conservation organization, and a local elected official.”
Advisory groups that are composed in compliance with these requirements complete the
review of State park management plans. Additional members may be appointed to the
groups, such as a representative of the park’s Citizen Support Organization (if one exists),
representatives of the recreational activities that exist in or are planned for the park, or
representatives of any agency with an ownership interest in the property. Special issues or
conditions that require a broader representation for adequate review of the management
plan may require the appointment of additional members. The DRP’s intent in making these
appointments is to create a group that represents a balanced cross-section of the park’s
stakeholders. Decisions on appointments are made on a case-by-case basis by Division of
Recreation and Parks staff.

Addendum 4—Soil Descriptions
John D. MacArthur Beach State Park
Soil Descriptions
4 – Arents - Urban land complex, 0 to 5 percent slopes - Arents consist
of nearly level, heterogeneous soil material. This material has been
excavated, reworked, and reshaped by earthmoving equipment. Arents
are near urban centers, phosphate-mining operations, major highways
and sanitary landfills.
Arents do not have an orderly sequence of soil layers. This map unit is
not associated with or confined to a particular kind of soil. Arents are
variable and contain discontinuous lenses, pockets, or streaks of black,
gray, grayish brown, brown, or yellowish brown sandy or loamy fill
material. The thickness of the fill material ranges from 30 to 80 inches
or more. Also included are small areas of soil that has slope that ranges
from 0 to 5 percent.
Most soil properties are variable. The depth to the seasonal high water
table varies with the amount of fill material and artificial drainage.
Permeability and the available water capacity vary widely from one area
to another.
9 - Beaches - This soil type occurs on narrow strips of tide washed sand
along the Atlantic Coastline. They range from less than 100 feet to
more than 500 feet wide, with an average width of 250 feet. As much
as half of the beach may be covered with water at daily high tides, and
all may be covered during storm events. Most beaches have a uniform,
gentle slope up to the edge of the ocean.
The beaches are frequently mixed and reworked by waves. They are
firm or compact near the water’s edge; the drier sands further up the
beach are loose. They consist of pale brown to light gray sand grains,
which are a mixture of quartz sand and fragments of seashells. The
entire beach is subject to wind and tides. Rock outcrops are scattered
throughout.
11 – Canaveral-Urban land complex, 0 to 5 percent slopes – This soil
type consists of very deep, somewhat poorly to moderately well
drained, very rapidly permeable soils on side slopes of dune-like ridges
bordering depressions and sloughs along the coast in lower Coastal
Plain of peninsular Florida. They formed in thick marine deposits of sand
and shell fragments. Canaveral soils have a water table within 10 to 40
inches of the surface for 2 to 6 months or more in an average year.
They can recede to a depth of 50 inches or more during dry periods.
Internal drainage is impeded by this shallow water table.
A 4 - 1
John D. MacArthur Beach State Park
Soil Descriptions
The surface layer is a dark grayish brown sand mixed with shell
fragments, about 8 inches thick. The next layer is pale brown to very
pale brown mixed sand and shell fragments, extending to 65 inches or
more.
These soils were formerly part of the Palm Beach series and are
geographically associated with Anclote, Delray, Palm Beach, Paola,
Pompano, St Lucie and Welaka soil series. Most areas of the Canaveral
soils remain in their natural state and function as wildlife habitat and
recreation. The native vegetation supported by this soil type includes
cabbage palm, scattered saw palmetto, magnolias, bays, and slash pine
with an understory of gallberry and pineland threeawn.
13 – Cocoa-Urban land complex, 0 to 5 percent slopes - This salicieous,
hyperthermic soil type consists of moderately deep, well drained,
rapidly permeable soils on upland coastal ridges near the Atlantic
Ocean. Slopes range from 0 to 8 percent. They formed in thin regolith
of sandy marine and eolian sandy sediments over porous, coquina
limestone. Permeability is rapid in all layers above the limestone.
Available water levels in the upper sandy layers are very low, and low in
the subsoil.
The upper layer consists of 3 inches of very dark grayish brown sand.
The next 5 inches are composed of dark red sand. The next layer is
loose yellowish red sand 14 inches thick. The subsoil is yellowish red,
friable sand about 8 inches thick. There is a hard coquina limestone
layer below the subsoil.
Cocoa soils are geographically associated with Astatula, Canaveral,
Orsino, Palm Beach, Paola, Parkwood, Pomello, and St Lucie soil series.
Most areas throughout the range of Cocoa soils are cultivated with
citrus being the principal crop. The native vegetation supported by this
soil type includes scattered live oak and laurel oak, cabbage palmetto,
magnolia, and pineland threeawn.
27 – Palm Beach-Urban land complex, 0 to 8 percent slopes - This soil
type consists of very deep, well to excessively drained, very rapidly
permeable soils on dune-like ridges that are generally parallel to the
Atlantic and Gulf Coastal Plain, principally in peninsular Florida. They
formed in regolith that is a marine deposit of thick beds of sand and
shell fragments.
Palm Beach soils are geographically associated with Anclote, Basinger,
Canaveral, Paola, Immokalee, Myakka, Pomello, Welaka and St. Lucie

John D. MacArthur Beach State Park
Soil Descriptions
soil series. They are similar to Canaveral soils, but have a water table
deeper than 6 feet. The Palm Beach soils consist of nearly level to
sloping, well drained, deep sandy soils.
The surface layer is dark grayish brown sand and shell fragments about
6 inches thick. The next layer is pale brown sand and shell fragments
about 34 inches thick. The next layer consists of light yellowish brown
sand and shell fragments, extending to a depth up to 80 inches or
more.
Native vegetation supported by this soil type includes cabbage palm,
running oak, saw palmetto, common seagrape, sea oats, bays and
oaks.
35 – Quartzipsamments, shaped, 0 to 5 percent slopes - This soil type
consists of well drained, deep, sandy soils in areas where natural soils
have been altered by cutting down ridges and spreading the soil
material over adjacent lower soils. This is done when low areas are
filled above natural ground level, and by filing and shaping soil material
(i.e. to form golf courses). The sandy fill material may be hauled in
from a distant location, but is usually obtained onsite by dredging
nearby water areas, or by excavating to create new water areas.
Permeability is very rapid, and available water capture is low.
There is not a standard soil layer pattern for this soil type. The most
common example has a surface layer of dark grayish brown sand about
6 inches thick. Next are stratified layers of gray, grayish brown, light
gray, light brownish gray, and white sand in any sequence and variable
thickness. The depth range of this strata is 6 to 32 inches. Below this
layer is a strong brown sand 10 inches thick with some dark reddish
brown fragments of weakly cemented sand. The next layer is a grayish
brown sand 18 inches thick. The last layer is about 80 inches of white
sand.
44 – Kesson mucky sand, tidal – This soil type consists of deep, very
poorly drained, rapid to moderately permeable soils that formed in thick
marine deposits of sand and shell fragments in tidal swamps and
marshes along the Gulf Coast and Southeast Coast of Peninsular
Florida. Slopes range from 0 to 1 percent.
Kesson soils are in tidal swamps and marshes that are flooded during
normal high tides. The color, texture, and thickness of the layers of this
soil vary from area to another. A common profile has the soil’s surface

layer of black, very dark gray, or very dark grayish brown and is 10
inches or more thick. It is a mucky sand or a mucky loamy sand. The
surface layer is fibrous muck 4 to 6 inches thick. The next layer is black,
very dark gray, very dark grayish brown, dark gray, gray, grayish
brown, or brown sand, fine sand, or loamy sand.
Kesson soils are geographically associated with Captiva, Myakka, and
Wulfert soil series. Kesson soils were formerly mapped as tidal swamp
and are function mainly for wildlife habitat. Native vegetation supported
by this soil type includes red, black and white mangroves, oxeye daisy,
and batis.

Addendum 6—Imperiled Species Ranking Definitions
Imperiled Species Ranking Definitions
A 6 - 1
The Nature Conservancy and the Natural Heritage Program Network (of which FNAI
is a part) define an element as any exemplary or rare component of the natural
environment, such as a species, natural community, bird rookery, spring, sinkhole,
cave or other ecological feature. An element occurrence (EO) is a single extant
habitat that sustains or otherwise contributes to the survival of a population or a
distinct, self-sustaining example of a particular element.
Using a ranking system developed by The Nature Conservancy and the Natural
Heritage Program Network, the Florida Natural Areas Inventory assigns two ranks
to each element. The global rank is based on an element's worldwide status; the
state rank is based on the status of the element in Florida. Element ranks are based
on many factors, the most important ones being estimated number of Element
occurrences, estimated abundance (number of individuals for species; area for
natural communities), range, estimated adequately protected EOs, relative threat of
destruction, and ecological fragility.
Federal and State status information is from the U.S. Fish and Wildlife Service; and
the Florida Fish and Wildlife Conservation Commission (animals), and the Florida
Department of Agriculture and Consumer Services (plants), respectively.
FNAI GLOBAL RANK DEFINITIONS
G1 ............. Critically imperiled globally because of extreme rarity (5 or fewer
occurrences or less than 1000 individuals) or because of extreme
vulnerability to extinction due to some natural or fabricated factor.
G2 ............. Imperiled globally because of rarity (6 to 20 occurrences or less than
3000 individuals) or because of vulnerability to extinction due to some
natural or man-made factor.
G3 ............. Either very rare or local throughout its range (21-100 occurrences or
less than 10,000 individuals) or found locally in a restricted range or
vulnerable to extinction of other factors.
G4 ............. apparently secure globally (may be rare in parts of range)
G5 ............. demonstrably secure globally
GH ............. of historical occurrence throughout its range may be rediscovered
(e.g., ivory-billed woodpecker)
GX ............. believed to be extinct throughout range
GXC ........... extirpated from the wild but still known from captivity or cultivation
G#? ........... Tentative rank (e.g.,G2?)
G#G# ........ range of rank; insufficient data to assign specific global rank (e.g.,

Addendum 7—Cultural Information
Management Procedures for Archaeological and Historical Sites and Properties on
State-Owned or Controlled Properties (revised March 2013)
A 7 - 1
These procedures apply to state agencies, local governments, and non-
profits that manage state-owned properties.
A.General Discussion
Historic resources are both archaeological sites and historic structures. Per Chapter
267, Florida Statutes, ‘Historic property’ or ‘historic resource’ means any prehistoric
district, site, building, object, or other real or personal property of historical,
architectural, or archaeological value, and folklife resources. These properties or
resources may include, but are not limited to, monuments, memorials, Indian
habitations, ceremonial sites, abandoned settlements, sunken or abandoned ships,
engineering works, treasure trove, artifacts, or other objects with intrinsic historical
or archaeological value, or any part thereof, relating to the history, government,
and culture of the state.”
B.Agency Responsibilities
Per State Policy relative to historic properties, state agencies of the executive
branch must allow the Division of Historical Resources (Division) the opportunity to
comment on any undertakings, whether these undertakings directly involve the
state agency, i.e., land management responsibilities, or the state agency has
indirect jurisdiction, i.e. permitting authority, grants, etc. No state funds should be
expended on the undertaking until the Division has the opportunity to review and
comment on the project, permit, grant, etc.
State agencies shall preserve the historic resources which are owned or controlled
by the agency.
Regarding proposed demolition or substantial alterations of historic properties,
consultation with the Division must occur, and alternatives to demolition must be
considered.
State agencies must consult with Division to establish a program to location,
inventory and evaluate all historic properties under ownership or controlled by the
agency.
C.Statutory Authority
Statutory Authority and more in depth information can be found at:
http://www.flheritage.com/preservation/compliance/guidelines.cfm
D.Management Implementation
Even though the Division sits on the Acquisition and Restoration Council and
approves land management plans, these plans are conceptual. Specific information
regarding individual projects must be submitted to the Division for review and
recommendations.
Management Procedures for Archaeological and Historical Sites and Properties on
State-Owned or Controlled Properties (revised March 2013)
A 7 - 2
Managers of state lands must coordinate any land clearing or ground disturbing
activities with the Division to allow for review and comment on the proposed
project. Recommendations may include, but are not limited to: approval of the
project as submitted, cultural resource assessment survey by a qualified
professional archaeologist, modifications to the proposed project to avoid or
mitigate potential adverse effects.
Projects such as additions, exterior alteration, or related new construction regarding
historic structures must also be submitted to the Division of Historical Resources for
review and comment by the Division’s architects. Projects involving structures fifty
years of age or older, must be submitted to this agency for a significance
determination. In rare cases, structures under fifty years of age may be deemed
historically significant. These must be evaluated on a case by case basis.
Adverse impacts to significant sites, either archaeological sites or historic buildings,
must be avoided. Furthermore, managers of state property should make
preparations for locating and evaluating historic resources, both archaeological sites
and historic structures.
E.Minimum Review Documentation Requirements
In order to have a proposed project reviewed by the Division, certain information
must be submitted for comments and recommendations. The minimum review
documentation requirements can be found at:
http://www.flheritage.com/preservation/compliance/docs/minimum_review_docum
entation_requirements.pdf .

Eligibility Criteria for National Register of Historic Places
A 7 - 3
The criteria to be used for evaluating eligibility for listing in the National Register of
Historic Places are as follows:
1)Districts, sites, buildings, structures, and objects may be considered to have
significance in American history, architecture, archaeology, engineering,
and/or culture if they possess integrity of location, design, setting, materials,
workmanship, feeling, and association, and:
a)are associated with events that have made a significant contribution to
the broad patterns of our history; and/or
b)are associated with the lives of persons significant in our past; and/or
c)embody the distinctive characteristics of type, period, or method of
construction, or that represent the work of a master, or that possess
high artistic values, or that represent a significant and distinguishable
entity whose components may lack individual distinction; and/or
d)have yielded, or may be likely to yield, information important in
prehistory or history.
2)Ordinarily cemeteries, birthplaces, or graves of historical figures; properties
owned by religious institutions or used for religious purposes; structures that
have been moved from their original locations; reconstructed historic
buildings; properties primarily commemorative in nature; and properties that
have achieved significance within the past 50 years shall not be considered
eligible for the National Register. However, such properties will qualify if they
are integral parts of districts that do meet the criteria or if they fall within the
following categories:
a)a religious property deriving its primary significance from architectural
or artistic distinction or historical importance; or
b)a building or structure removed from its original location but which is
significant primarily for architectural value, or which is the surviving
structure most importantly associated with a historic person or event;
or
c)a birthplace or grave of an historical figure of outstanding importance
if there is no appropriate site or building directly associated with his
productive life; or
d)a cemetery which derives its primary significance from graves of
persons of transcendent importance, from age, distinctive design
features, or association with historic events; ora reconstructed
building, when it is accurately executed in a suitable environment and
presented in a dignified manner as part of a restoration master plan,
and no other building or structure with the same association has
survived; or a property primarily commemorative in intent, if design,
age, tradition, or symbolic value has invested it with its own
exceptional significance; or
e)a property achieving significance within the past 50 years, if it is of
exceptional importance.
Preservation Treatments as Defined by Secretary of Interior’s Standards and
Guidelines
A 7 - 4
Restoration is defined as the act or process of accurately depicting the form,
features, and character of a property as it appeared at a particular period of time
by means of the removal of features from other periods in its history and
reconstruction of missing features from the restoration period. The limited and
sensitive upgrading of mechanical, electrical and plumbing systems and other code-
required work to make properties functional is appropriate within a restoration
project.
Rehabilitation is defined as the act or process of making possible a compatible
use for a property through repair, alterations and additions while preserving those
portions or features that convey its historical, cultural or architectural values.
Stabilization is defined as the act or process of applying measures designed to
reestablish a weather resistant enclosure and the structural stability of an unsafe or
deteriorated property while maintaining the essential form as it exists at present.
Preservation is defined as the act or process of applying measures necessary to
sustain the existing form, integrity and materials of an historic property. Work,
including preliminary measures to protect and stabilize the property, generally
focuses upon the ongoing maintenance and repair of historic materials and features
rather than extensive replacement and new construction. New exterior additions
are not within the scope of this treatment; however, the limited and sensitive
upgrading of mechanical, electrical and plumbing systems and other code-required
work to make properties functional is appropriate within a preservation project.

The Florida Department of Environmental Protection, Division of Recreation and Parks, Office of Park
Planning is responsible for the unit management planning of all Florida State Parks. As part of this
planning process, prior to the unit management plan being presented to its Acquisition and Restoration
Council for consideration, the Office of Park Planning is required to connect and communicate with the
area’s agency that is responsible for the local comprehensive plan to determine if the park unit
management plan is in compliance with the comprehensive plan. Specifically, we want to make sure we
are accurately citing the future land use and zoning designations for the park and would like to confirm
that our proposed developments in the conceptual land use section comply with those
designations. The existing facilities section will also need to be reviewed.
We would like to have the attached John D. MacArthur Beach State Park’s unit management plan
reviewed. Please let me know if this can be done, who the point person is for hurthese requests (for
future needs) and an approximate turn-around time for the review. Of course, if you need any
