Agenda 01/28/2020 Item #16D 3 (Conservation Collier - 5 yr update of Rivers Road Preserve)01/28/2020
EXECUTIVE SUMMARY
Recommendation to approve the Rivers Road Preserve Final Management Plan 5-year update
under the Conservation Collier Program.
OBJECTIVE: To obtain approval from the Board of County Commissioners (Board) for the Rivers
Road Preserve Final Management Plan (FMP) 5-year update.
CONSIDERATIONS: The Conservation Collier Ordinance, No. 2002-63, as amended, Section 14(3),
requires that a FMP be prepared for each property and updated every five (5) years, with review and input
by the Conservation Collier Land Acquisition Advisory Committee (CCLAAC).
Rivers Road Preserve is comprised of 76.74 acres and is located approximately 2.5 miles east of Collier
Boulevard (CR 951) south of Immokalee Road. The last parcel of the preserve was purchased by Collier
County in 2010. The original Final Management Plan was approved by the Board on May 27, 2014,
Agenda Item #16D2. The preserve officially opened to the public in May 2016.
The updated FMP includes updated maps, additions to plant or animal lists, status of exotic plant
infestations, added amenities, streamlining of text, and revision of the management budget. This 5-year
update was approved by the CCLAAC on September 9, 2019.
FISCAL IMPACT: There is no new major fiscal impact associated with approving this management
plan update. Annual costs are estimated at $10,300 per year for the next five (5) years, primarily for
invasive exotic plant and trail maintenance. Funds are available within Conservation Collier Land
Management Trust Fund (174) to accomplish these activities.
GROWTH MANAGEMENT IMPACT: Management of Conservation Collier lands to support
appropriate public access is consistent with and supports Policy 1.1.6 and Objective 1.3 in the Recreation
and Open Space Element of the Collier County Growth Management Plan. There is no specific Growth
Management impact associated with this Item.
LEGAL CONSIDERATIONS: The Conservation Collier Ordinance (No. 2002-63, as amended), in
Section 14, provides a legal framework for the development of management plans and for use of
environmentally sensitive lands. This item is approved for form and legality and requires a majority vote.
-JAB
RECOMMENDATION: To approve the attached proposed Final Management Plan 5-year update for
the Rivers Road Preserve and directs staff to implement the updated plan.

1.0 Introduction
The Rivers Road Preserve is a 76.74 acre preserve located approximately 2.5 miles east of
Collier Boulevard (CR 951) within the Rural Fringe Mixed Use District (Receiving Area) in
Collier County, Florida. Current access to the preserve is from Rivers Road on the west or from
Moulder Drive to the east. The preserve is comprised of a mix of vegetative communities,
including pine flatwoods, mixed wetland hardwoods, cypress and wetland forested mixed, with
small areas of freshwater marsh and inland ponds and will serve the public as a wildlife viewing
area.
The Preserve was purchased by Collier County in two phases. The first 62.98 acres were
purchased in December 2008, followed by an additional 13.76 acres in 2010. The County holds
fee simple title. The preserve was officially named on December 22, 2008 and was opened for
public access in May 2016. A nature trail, benches, picnic area, educational kiosk, and
interpretive signs are available for public use
The Conservation Collier Program manages this parcel under authority granted by the
Conservation Collier Ordinance 2002-63, as amended (available from www.municode.com).
Conservation, restoration and passive public recreation are the designated uses of the property.
Management activities allowed are those necessary to preserve and maintain this
environmentally sensitive land for the benefit of present and future generations. Public use of
this site must be consistent with these goals.
An Interim Management Plan for Rivers Road Preserve was approved by the Collier County
Board of County Commissioners (BCC) in 2011. This is the Final Management Plan for the
Rivers Road Preserve. This management plan was approved by the BCC in May 2014. Updates
to the plan will be completed every 5 years.

1.1 Conservation Collier: Land Acquisition Program and Management Authority
The Conservation Collier Program was originally approved by voters in November 2002 and
subsequently confirmed in the November 2006 ballot referendum. Both voter-approved
referendums enable the program to acquire environmentally sensitive lands within Collier
County, Florida (Ordinance 2002-63, as amended). Properties must support at least two of the
following qualities to qualify for consideration: rare habitat, aquifer recharge, flood control,
water quality protection, and listed species habitat. The BCC appointed a Conservation Collier
Land Acquisition Advisory Committee (CCLAAC) to consider any selected or nominated
properties that an owner has indicated a willingness to sell. The committee recommends
property purchases for final approval by the BCC.
Lands acquired with Conservation Collier funds are titled to “COLLIER COUNTY, a political
subdivision of the State of Florida, by and through its Conservation Collier program.” The
Board of County Commissioners of Collier County established the Conservation Collier Program
to implement the program and to manage acquired lands. As such, Conservation Collier holds
management authority for the Rivers Road Preserve.
1.2 Purpose and Scope of Plan
The purpose of the plan is to provide management direction for the Rivers Road Preserve by
identifying the goals and objectives necessary to eliminate or minimize any threats to the
resources and integrity of the preserve. This text is a working document that establishes the
foundation of a ten-year plan by identifying the appropriate management techniques necessary to
preserve and/or restore the resource.
This plan will balance resource restoration and protection with natural resource-based
recreational and educational use while looking at listed species protection and maintenance of
the site free of invasive, exotic plant and animal species. This plan is divided into sections that
include an introduction, descriptions of the natural and cultural resources, projected uses of the
property, and management issues, goals and objectives.
1.3 Location
The Rivers Road Preserve property is located approximately 2.5 miles east of Collier Boulevard
(CR 951) within the Rural Fringe Mixed Use District (Receiving Area) in Collier County,
Florida (Figures 1 & 2). Single family homes exist to the north, east and west of the property,
with one private residence within the boundaries of the preserve. A private Conservation
Easement exists to the south. A church encompassing several parcels exists to the north and
northeast of the property along with a parcel that contains remnants of a small tree nursery. It is
located in Township 48, Range 27 and Section 30, in Collier County, Florida. The legal
descriptions are attached as Appendix 1.

1.4 Regional Significance
Despite having 881,070877,000 acres, or 68%, of County lands protected in conservation status
(FNAI, Feb 20193), Collier County has lost, and is losing, many of its rare and unique habitats.
The Conservation Collier Ordinance (2002-63, as amended) identifies these specific habitats and
gives preference to them in acquisition evaluations. These habitats include, in order of
preference: tropical hardwood hammocks, xeric oak scrub, coastal strand, native beach, riverine
oak, high marsh (saline) and tidal freshwater marsh. Although the Rivers Road Preserve does
not contain any of these preferred habitats; it does contain eight observed native plant
communities and outstanding examples of pop ash swamp, other wetland dependent plant
species and several listed plant species. The habitat observed and the location supports the
presence of approximately nine listed species and many non-listed wildlife species. This
preserve provides habitat for the listed Florida panther (Puma concolor coryi) with several
telemetry points and other observations of non-collared panthers on the preserve and in close
proximity. The protection and management of these listed species and their habitat is critical to
their long term existence in Collier County and throughout their ranges. The preserve is adjacent
to and contributes to an important wildlife corridor connecting two private conservation
easements through a wildlife crossing under Immokalee Road to the over 60,000 acre Corkscrew
Regional Ecosystem Watershed (CREW) owned by the South Florida Water Management
District and Audubon of Florida’s Corkscrew Swamp Sanctuary (See Figure 3).

1.6 Public Involvement
Neighborhood involvement was sought through direct mailing notices for public meetings to
residents within the surrounding area, owners of properties that border the preserve, and
organizations with an interest in the preserve. Any major changes or management activities,
such as prescribed fire that are likely to generate an intrusive aspect or that in some way affect
neighboring properties will be reviewed with these contacts prior to conducting the activity.
Preserve activities will be posted on the Conservation Collier website and also through public
notices. Staff will also seek volunteers and partnerships through these contacts.
Two local Boy Scouts completed their Eagle Scout Projects on the preserve. In 2014, Joseph
Reems Landrith built and donated a large picnic table and four benches that were placed in the
picnic area and along the hiking trails. In 2017, Thomas Hogle built an educational kiosk that
was installed next to the parking area (see photos below). Both projects have benefited the
preserve experience for visitors and will continue to do so for years to come.
Staff will continue to work with local Boy and Girl Scout troops and may attempt to partner with
neighboring churches. Naples Church to the north has a preserve to the south of their property
that is directly adjacent to the Rivers Road Preserve along the northeast side. Staff will attempt
to work with them to coordinate management activities.
2.0 Natural and Cultural Resources
2.1 Physiography
The Rivers Road Preserve lies within the Southwestern Flatwoods District. This largely low, flat
district was developed on rocks and sediments that range mainly form Miocene to Pleistocene in
age. Surficial materials are dominantly sand (often with relatively clayey substrate) limestone
and organic deposits (Myers & Ewel 1990).
2.1.1 Topography and Geomorphology
The preserve is located in the Southwestern Slope region of the South Florida Water
Management District. Topography has been established using a Light Detecting and Ranging
(LIDAR) map (Figure 4). The topographic contours of the preserve range from 7 feet in the pop
ash areas and around the man-made lake to 14 feet in the upland areas.
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 14
2.1.2 Hydrology/Water Management
Flat topography, sandy soils and seasonal
precipitation strongly influence hydrological
processes in flatwoods. During the rainy season,
flatwood soils become saturated and poorly
aerated and there may be standing water for
varying periods of time. During the dry season
however, high evapotranspiration draws much
water from the upper horizons thus soil moisture
becomes rapidly depleted and persistent drought
conditions result (Myers & Ewel 1990). A small
pond was excavated in 2000 on a residential
property to the east of the preserve, with a portion
of the pond within the preserve. The northern
portion of the preserve has an unpaved road
running alongside the western boundary while
another unpaved road is just beyond the eastern
boundary. In between the two roads and to the
north of the preserve are just over 30 acres of
land currently being used for church buildings
and mostly cleared open space. To the south of the
property is the Olde Florida Golf Course
Conservation Area that was set aside when the golf
course was built in the early 1990s. No water
management structures exist on the preserve and no
water management improvements are planned for
the future. The property is mapped by the South
Florida Water Management District (SFWMD) to
contribute significantly to the Lower Tamiami
aquifer at 21”-102” annually and the surficial aquifer significantly at 56”-67” annually.
2.1.3 Geology
The geology of Collier County is characterized by complex sequences of interbeded sands, clays,
and limestone. Closest to the surface is the Holocene aged Pamlico Sand Formation,
approximately ten feet thick and composed primarily of unconsolidated quartz sand and some
silt. The Pamlico Sand unconformably overlies the Pleistocene aged Fort Thompson and
Caloosahatchee Formations, which vary from a few feet to more than twenty feet in thickness
and are characterized by shelly and sandy limestone with vugs and solution cavities (Miller
1986).
Below the Fort Thompson and Caloosahatchee Formations are the Ochopee and Buckingham
Members of the Pliocene aged Tamiami Formation, which are at least 200 feet thick in the
surrounding areas (Oaks & Dunbar 1974). The Ochopee Limestone unconformably overlies the
Buckingham Limestone and/or the equivalent Cape Coral Clay. This unconformity marks the
bottom of the surficial aquifer separating it from the brackish underlying aquifer below. Then
the Hawthorn Formation, rich in phosphate and other heavy minerals (Scott 1988), overlies the

Conservation Collier Program 15
Figure 5. Rivers Road Preserve Soils
Map
Oligocene age Suwannee Limestone and Eocene age Ocala Limestone that form the Floridan
Aquifer System in Southwestern Florida.
2.1.4 Soils
Soils data is based on the Soil Survey of Collier County,
Florida (USDA/NRCS, 1990, rev. 1998). Approximately
55% of the soils mapped on this preserve are Riviera fine
sand, limestone substratum, a hydric soil. This nearly
level, poorly drained slough soil usually supports
scattered areas of South Florida slash pine, cypress,
cabbage palm, wax myrtle, sand cord grass,
gulf muhly, blue maidencane, South Florida Bluestem
and chalky bluestem. Vegetation observed in the
preserve areas containing this soil includes South Florida
slash pine, cypress, cabbage palm, and wax myrtle.
Approximately 45% of the soils mapped on this preserve
are Boca fine sand, a non-hydric soil. This nearly level,
poorly drained soil usually supports scattered areas of
pine and cabbage palm and an understory of saw
palmetto, chalky bluestem, creeping bluestem, lopsided
Indiangrass, and pineland threeawn. Vegetation observed
on the preserve where these soils are contained includes
cabbage palms with an understory of saw palmetto and
some pines.
2.2 Climate
The Rivers Road Preserve is located in an area of Florida that is influenced by both a humid
subtropical climate and a tropical savanna climate in which temperatures are moderated by winds
from the Gulf of Mexico and the Atlantic Ocean. A tropical savanna climate is characterized by
sharply delineated wet and dry seasons and average monthly temperatures greater than 64º
Fahrenheit. Monthly rainfalls may exceed ten inches during the wet season. Humid subtropical
climates are characterized by less extreme rainfall fluctuations between wet and dry seasons and
average monthly temperatures less than 64º Fahrenheit in some months.
The average annual temperature for this portion of Collier County is approximately 75º
Fahrenheit. The warmest months are usually July and August. The humidity is high during
these months but frequent afternoon thunderstorms prevent excessively high temperatures.
Two-thirds of the annual rainfall occurs in the wet season from May to October. Thunderstorms
are frequent during the wet season occurring every two out of three days between June and
September. Rainfall records for the area indicate that there is no significant variation in the
annual rainfall throughout much of the county; however, large variations often occur during a
single year. The hurricane season extends from June through November with peak activity
occurring in September and October when ocean temperatures are highest.

2.3 Natural Plant Communities
A plant community refers to the suite of plant species that form the natural vegetation of any
place. In addition to anthropogenic influence, the combination of factors such as geology,
topography, hydrology, underlying soils and climate determine the types of plants found in an
area. These plants in turn determine the animal species that may be found in an area.
The Florida Land Use, Land Cover Classification System (FLUCCS) GIS layer provided by the
South Florida Water Management District classifies the entire preserve as a combination of Pine
Flatwoods-Melaleuca Infested, Mixed Wetland Hardwoods, Cypress-Melaleuca Infested and
Wetland Forested Mixed (Figure 6). Site evaluations confirm the Pine Flatwoods, Mixed
Wetland Hardwoods, Cypress and Wetland Forested mixed designations, however, very few
melaleuca trees were observed throughout the preserve. Other communities observed include
Freshwater Marsh, Cabbage Palm, Pine/Cabbage Palm, Cypress/Cabbage Palm Disturbed,
Cypress, Pine, Cabbage Palm, and Inland Ponds and Sloughs.
When purchased, the preserve also had several
cleared areas, several areas designated for single
family residences, a portion of a small pond
excavated in 2000 and several infestations of exotic
plants, including 25-40% coverage of Brazilian
Pepper (Schinus terebinthifolia) and a significant
infestation of air potato (Dioscorea bulbifera)
throughout on the western side of the preserve and
on the southeastern portion as well. Exotic
treatments have been done bi-annually and annually
since then and the preserve is now in maintenance
state. Additional details are provided in Section 2.6
and plans for management of exotics will be covered
in the Invasive, Exotic Plant Species Control Plan
(Table 10).
Figure 6: Rivers Road Preserve Land Cover / Land
Use Map
2.4 Native Plant and Animal Species
The 76.74 acre preserve is a combination of Cabbage Palm, Inland Ponds and Sloughs, Mixed
Wetland Hardwoods, Cypress, Pine Flatwoods, Mixed Wetland Forests and Freshwater Marsh.
The preserve also contains an outstanding example of pop ash swamps and several wetlands.
One hundred sixty-two vascular plant species were recorded on the preserve and 36 (22%) of
these plants are indicated as not native to our area (Appendix 2). All invasive exotic plants will
require removal and maintenance. The canopy is dominated by slash pine trees (Pinus elliottii),
cabbage palms (Sabal palmetto), scattered cypress (Taxodium ascendens) in the upland areas.
Willow (Saliz caroliniana), pop ash (Fraximus caroliniana) and red maple (Acer rubrum) can be
found in the wetland areas. The midstory contains areas of ragweed (Ambrosia sp.), dogfennel
(Eupatorium capillifolium), sawgrass (Cladium jamaicense), saw palmetto (Serenoa repens),
American beautyberry (Callicarpa americana) and myrsine (Rapanea punctata). The

and sagittaria (Sagittaria lancifolia), amongst other groundcovers common in Pine/Cabbage
Palm communities and freshwater marsh communities. Ephiphytes and vines have been
observed throughout the preserve. Listed plant species include common wild pine (Tillandsia
fasciulata), hand fern (Ophioglossum palmatum) and reflexed (inflated) wild pine (Tillandsia
balbisiana).
Occurrences of fauna at the preserve are based on direct visual and auditory observations of
animals by Collier County staff and outside researchers during site visits or evidence of activity
such as spoor, scat, or burrows, and from the site information available in documents such as:
the site’s initial criteria screening report,
the property’s interim management plan,
anecdotal information from persons with knowledge of the site.
Mammal species known to occur or individuals and/or evidence of activity directly observed
within the preserve include the white-tailed deer (Odocoileus virginianus), bobcat (Lynx rufus),
Florida black bear (Ursus americanus floridanus), racoon (Procyon lotor), opossum (Didelphis
virginiana), armadillo (Dasypus novemcinctus), and wild feral hogs (Sus scrofa). Numerous
Florida panther (Puma concolor coryi) telemetry points and photo accounts have been recorded
in the area and one point was recorded approximately 1/3 mile from the preserve. There is a
wildlife underpass under Immokalee Road north of the preserve that provides access through the
Twin Eagles subdivision to over 60,000 acres of conservation lands, including state-owned
lands, Audubon’s Corkscrew Swamp and the Corkscrew Ecosystem Lands. Bird observations by
Collier County staff are included in Table 3.

The Florida Breeding Bird Atlas lists 32 bird species that have been recorded as confirmed,
probable, or possibly breeding in the vicinity of the site (in Corkscrew SW USGS quadrangle)
that may be present at Rivers Road Preserve (Table 4). The Breeding Bird Atlas documents
breeding distributions of all bird species in Florida between 1986 and 1991. Some of these
species may breed at the Rivers Road Preserve.

Cottonmouth/Water Moccasin (Agkistrodon piscivorous conanti)
and the Southern Black Racer (Coluber constrictor priapus). There
have been no amphibian species observed on the site to date besides
the exotic brown anole (Anolis sagrei), however staff will continue
to monitor the site during site visits and will document any other
reptiles and/or amphibians found.
Invertebrates observed at the preserve
include butterflies such as Queen

Other wildlife species that have not been recorded undoubtedly occur at Rivers Road Preserve.
Future, more detailed, wildlife surveys will be conducted on the preserve and the plan will be
updated as new species are documented.
2.5 Listed Species
Official listings of rare and endangered species are produced at the federal level by the U.S. Fish
and Wildlife Service and the National Marine Fisheries Service, and at the state level by the
Florida Fish and Wildlife Conservation Commission and the Florida Department of Agriculture
and Consumer Services. FNAI produces a list of rare and endangered species, and maintains a
database of occurrences of these species in Florida.
2.5.1 Listed Plant Species
Three plant species found at the Rivers Road Preserve are listed by the Florida Department of
Agriculture and Consumer Services (FDACS) - (2) as Endangered, (1) as Threatened, and none
as Commercially Exploited. There are no federally listed endangered or threatened plant species.
A brief description of these species and their status is included in Table 5 and in the following
paragraphs. Additional listed plant species may be found at Rivers Road Preserve following
further field surveys. Confirmation of listed plant identifications should be made by a qualified
botanist.

Common Names Scientific Names FDACS (State)
Hand fern Ophioglossum palmatum Endangered
Reflexed wild pine Tillandsia balbisiana Threatened
Stiff-leaved wild pine Tillandsia fasciculata Endangered
Giant wild pine Tillandsia utricula Endangered
Hand Fern (Ophioglossum palmatum)
This plant is commonly found on cabbage palms and has been
found in multiple areas along the east and southern coast of
Florida. Early 20th century observers spoke of hand fern
gathered by the wagon load from Florida’s swamps. Hand fern
is still collected but it dies in cultivation due to lack of essential
fungi. When palm boots decay and fall to the ground, or are
destroyed by fire, hand ferns are killed. Only 50 populations
remain in Florida, about half in conservation areas.
Hand fern found on site.

Reflexed wild pine (Tillandsia balbisiana)
This air plant is abundant and occurs throughout the preserve. It is also
considered threatened by the State of Florida due to the Mexican
Bromeliad Weevil. It is equally well-adjusted to deep shade where leaves
grow long or to bright sunlight where they are contorted and highly colored
from gray-green to blue-bronze or red (NAS 2007).

Stiff-leaved wild pine (Tillandsia fasciculata)
Although this air plant is abundant throughout South Florida, it is listed
by the State as endangered as they are threatened by the Mexican
Bromeliad weevil. Leaves may grow to as much as forty inches, they
form large plants in tree tops and are often mistaken for bird or squirrel
nests. They grow equally well in canopy or near ground (NAS 2007). It
is also referred to as a common wild pine or cardinal air plant. This air
plant has been noted in several areas throughout the preserve. The
photo to the left was taken in the northern portion of the preserve within
a small pop ash marsh.
Giant wild pine (Tillandsia utriculata) is the largest epiphyte and is
relatively common in hammocks and swamps in South Florida. It can reach
12-30 inches in height and its flower spike may be more than six feet in
height. It is also listed by the State of Florida as endangered
+
2.5.2 Listed Wildlife Species
The Florida Natural Areas Inventory (FNAI) maintains a database of occurrences of rare,
threatened, and endangered species in Florida. Within the Rivers Road Preserve, The Florida
Natural Areas Inventory (FNAI) has documented the occurrence of the endangered Florida
panther (Puma concolor coryi) (Appendix 3). The FNAI database report indicated three (3)
other species likely to be found in this area including Florida back bear (Ursus americanus
floridanus), Mangrove fox squirrel (Sciurus niger avicennia), and the Wood stork (Mycteria
americana). Florida black bear have been detected and documented by the former property
owners on the southern portion of the preserve. The habitat of the preserve also supports the
presence of Gopher tortoise (Gopherus polyphemus), Eastern indigo snake (Drymarchon
couperi), Florida bonneted bat (Eumops floridanus), and Snail kite (Rostrhamus sociabilis
plumbeus). Table 6 below identifies the status of each and a brief description of the only

Florida Black Bear (Ursus americanus floridanus)
The Florida black bear is a subspecies of the black bear found throughout North America. Black
bears have been observed on several occasions at Rivers Road Preserve. Florida black bears in
south Florida are listed as threatened by the FWC. Because of its large home range and low
population density the black bear is particularly vulnerable to habitat loss. Even though their
population is affected by illegal killing and road kills, habitat loss is the major cause of concern
(Humphrey 1992).

Preserve. Photos taken by former property
owner Hans VanCleve.
Cottonmouth/Water Moccasin (Agkistrodon piscivorous conanti)
Cottonmouth snakes are listed as a species of special concern by the State of Florida. The coloration of
this snake can be variable. Older and larger snakes tend to be uniformly black, brown to reddish
brown, while the young are banded with a dark color against a lighter background. Most
abundant in flooded woodlands, the Florida Cottonmouth is also found around rivers, streams
and ponds. It is often seen along the water's edge, on the bank or on a log or rock and it can also
be found in pine woods or other dry habitats. Though the Cottonmouth occurs throughout the
state, it is not as abundant as the many species of harmless water snakes that occur in much the
same habitat.
Florida Panther (Puma concolor coryi)
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 22
This large cat is a year-round resident of undeveloped lands in South Florida. The Florida
Panther is listed as a Federally and State endangered species. The U.S. Fish and Wildlife Service
and FWC track radio-collared panthers in Collier County. Radio telemetry reports as well as
wildlife camera photos of non-collared panthers have verified that Panthers do pass through this
area. These large cats require extensive blocks of mostly forested communities. Large wetlands
that are generally inaccessible to humans are important for diurnal refuge. A large tract of land
may be developed to the east of the preserve within the next couple of years. Environmental
groups have worked with the developer to protect a vital wildlife corridor along the western
boundaries of their developmental area. This corridor connects two conservation areas and runs
through a wildlife underpass under Immokalee Road (see Figure 7). The corridor is currently
part of a SFWMD environmental resource permit and most likely will become part of the
developer’s required preserve area. Wildlife cameras have captured photos of Florida Panther on
the Rivers Road Preserve hiking trails in June 2018 (see photo below).

2.6 Invasive, Non-Native and Problem Species
Several invasive, non-indigenous plant and animal species are known to occur within Florida. A
comprehensive list of invasive plant species is available from the Florida Exotic Pest Plant
Council (FLEPPC). Although Florida does not have an official invasive, non-indigenous animal
species list, at least 400 exotic fish and wildlife animal species have been reported, and
approximately 125 species are established.
2.6.1 Exotic Wildlife Species
Evidence of wild hog (Sus scrofa) exists on the preserve,
multiple hog wallows are present, especially in the southern
portion of the preserve indicating this species could potentially
become a nuisance. They can also be referred to as wild boar or
feral pig, and may have been introduced to Florida as early as
1539 (FFWCC 2002). According to Kevin Love, a land
manager with the Southwest Florida Water Management
District, “Feral hogs are a big problem on all conservation lands.
[They are] one of the most severe exotic problems facing
Florida.” Their favorite food is acorns but they roam in large
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 24
groups and will eat native frogs, snakes and ground nesting birds while rooting up the ground
with their snouts – destroying acre upon acre. They may weigh over 150 pounds, grow to be 5-
6 feet long and reproduce at a rapid rate. They travel in herds containing several females and
their offspring. Wild hogs occur throughout Florida in various habitats, but prefer moist forests,
swamps and pine flatwoods. They are omnivorous and feed by rooting with their broad snouts.
They may cause great damage of the understory and leave an area looking like a plowed field
(Hoppe 2006). Feral hogs consume ground-nesting bird eggs and disturb soil and sensitive
vegetation, which in turn invites invasive exotic plant growth.
2.6.2 Invasive and Problem Plant Species
Invasive and exotic plants on the preserve include air potato (Dioscorea bulbifera), Brazilian
pepper (Schinus terebinthifolia), earleaf acacia (Acacia auriculiformis), Caesar’s weed (Urena
lobata), bougainvillea (Bougainvillea glabra), citrus (Citrus spp.), lantana (Lantana camera),
java plum (Syzygium cumini), rosary pea (Abrus precatorius), melaleuca (Melaluecua
quinquenervia), monk orchid (Oeceoclades maculata), tabeubuia (Tabeubuia spp.), and wedelia
(Wedelia trilobata). Other plants that are non-native include tabeubuia (Tabeubuia spp.),
bougainvillea (Bougainvillea glabra), citrus (Citrus spp.), and monk orchid (Oeceoclades
maculata). All FLEPPC listed invasive, exotic plants documented on the preserve are listed in
Table 7.
Of the exotic plants found on the preserve, the 2019 Florida Exotic Pest Plant Council List
considers elevennine of these species to be Category I Invasive plants that may alter native plant
communities by displacing native species, changing community structures or ecological
functions, or hybridizing with natives. FiveThreeFour species are considered Category II plants,
meaning they have increased in abundance or frequency but have not yet altered Florida plant
communities to the extent shown by Category I species. These definitions do not rely on the
economic severity or geographic range of the problem, but on the documented ecological
damage caused (FLEPPC 2007). Treatment of these species is covered in Section 4.4, Goal 3
and in Table 11.

The majority of the Brazilian pepper and air potato once present were located within the
disturbed areas of the preserve, such as the power line corridors and pathways that may have
previously been used to traverse the property. Air potato mainly existed primarily in areas where
dilapidated structures were removed prior to County purchase of the property. These areas have
been treated several times over the past 5 years and minimal infestation remains.
Under certain conditions, especially following hydrologic disturbance, some native plant species
can become invasive. For example, Cabbage palms can also become invasive when hydrology is
altered and without fire. Management of these species may be necessary.
2.7 Forest Resources
No commercial forests exist, and timber extraction may not appropriate for this site. If portions
of the preserve require thinning, prescribed fire could assist to thin out young pines.
2.8 Archaeological, Historical and Cultural Resources
The Rivers Road Preserve property is not within an area of historical and archaeological
probability. According to a letter obtained by County Staff dated, January 8, 2013, the Florida
Master Site file of the Division of Historical Resources show that no archaeological sites or any
other cultural resources have been recorded for the section, township and range in which the
preserve exists (see Appendix 4). The County will notify the Division of Historical Resources
immediately if evidence is found to suggest otherwise. If such resources are identified on-site,
staff shall cordon off the area, and a professional survey and assessment shall be instituted. The
archaeologist shall prepare a report outlining results of the assessments and issue
recommendations to County staff about management of any sites discovered, per provisions of
the Land Development Code Section 2.2.25. This report shall be sent to the Division of
Historical Resources. The County shall cooperate fully with direction from the Division of
Historical Resources on the protection and management of archaeological and historical
resources. The management of these resources will comply with the provisions of Chapter 267,
Florida Statutes, specifically Sections 267.061 2 (a) and (b).

3.0 Use of the Property
3.1 Previous and Current Use
Figure 8. 1985 Aerial Map (Collier County Property Appraiser’s Office)
Historical Aerials were researched back to 1940, however, flights were taken to the north, east
and west of the property but not directly over the current preserve property. The 1958 aerial
shows that Immokalee Road had been built to the north with no additional development
surrounding. The 1963 surrounding aerials showed new roads and existing farm fields to the
west. The 1973 aerials showed small roads being cleared just east of Rivers Road and one parcel
cleared just south of Immokalee Road where the Living Word Church now exists and some small
homes N, E, and W of the preserve. The 1985 aerial (Figure 8) shows that the majority of the
preserve land was still undeveloped and undisturbed. River’s Road existed at that time. A small
home existed on the Northwestern most parcel and some clearing and single family development
had occurred on the two parcels west of Rivers Road. The area that will be used as the parking
area (discussed later in the plan) was cleared sometime between 1975 and 1985.
The majority of the site was previously zoned agriculture with a Mobile Home Overlay, allowing
for minimal development at no greater than one unit per five acres. There were a few small
structures on the site such as sheds and trailers, including one abandoned trailer. Several
formerly cleared roads cut across portions of the property to serve as access to power lines and/or
to allow the former property owners access. A small pond constructed on an adjacent parcel to
the east overlaps onto the preserve. The entire perimeter of the pond has been cleared and
sawgrass, sagittaria, ragweed, willow, red maple, cypress trees, pine and cabbage palms surround
the clearing. Prior to conveyance of the properties, a significant amount of trash and debris was
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 27
removed by the former property owners, including several very dilapidated structures scattered
throughout.
The site is accessed by Rivers Road, which is off Immokalee Road. Currently the site is not
open to the public for recreational use and a locked gate permits access to some portions only to
those with permission to visit the property and to the property owner that owns a 5-acre out-
parcel within the preserve. Recent site visits have revealed small pockets of trash in several
areas. On the northern portion of the preserve, there is evidence that a small structure may have
been once used and abandoned. Water piping and timber is piled up and nearby there is fencing
and old appliances near the property line.
The preserve public use area can be accessed by Rivers Road, a
gravel road, off of Immokalee Road. Temporary signs identifying the
property as a Conservation Collier Preserve and listing prohibited
activities have been posted at the northern most part of the preserve
along Rivers Road and Moulder Drive. There are no current
concessions or leases on the preserve property.
Evidence that the preserve has been used for baiting and possibly
hunting has been found near the property line so coordination with
neighbors will be critical as restoration plans are implemented,
particularly during active restoration, prescribed burns and when public access is granted.
Following removal of old structures, including septic tanks and trailers, the southwestern portion
of the property is beginning to show signs of natural restoration, with natural recruitment of
pines, grasses and myrtle. Continual treatment and removal of exotics will further encourage
natural revegetation.
3.2 Public Uses and Assessment of their Impacts
The preserve is open to the public for hiking, bird watching, picnicking, and horseback riding.
Public access will be limited to special requests until initial exotics are removed and safe trails
are established. Future planned uses include passive recreational opportunities for the public.
Public hunting is not allowed within the preserve. Details of planned uses for the Rivers Road
Preserve and assessment of their potential impacts are provided in the following sections.
3.3 Identification of Public Uses Consistent with Preservation, Enhancement, Restoration,
Conservation and Maintenance of the Resources.
The Conservation Collier Ordinance 2002-63 constrains the use of this property to “primary objectives of managing
and preserving natural resource values and providing appropriate natural resource-based recreational & educational
opportunities.” Natural resource-based recreation shall mean all forms of uses, which are consistent with the goals of
this program, and are compatible with the specific parcel (Ord. No. 02-63, as amended§ 5, 12-3-02). Additionally,
no dumping, use of unauthorized vehicles, or removal or destruction of natural or historical/archaeological resources
will be permitted within the preserve. The goal is to allow limited, non-destructive public access to native plant
communities and animal species. Currently, the preserve rules are those identified in Collier County Ordinance
2011-38 (available from www.municode.com), as amended.
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 28
As defined in Ordinance 2002-63, as amended, Section 5.9, the following are natural resource-
based uses consistent with Rivers Road Preserve:
Hiking: Consistent with the nature of the site and its purpose.
Nature Photography: There is potential for nature photography of wildlife and plant life.
Bird Watching: There is potential for worthwhile bird watching on this site.
Environmental Education: special requests for guided hikes for groups can be arranged
with Conservation Collier Staff. Educational signage will be posted in the kiosk.
3.4 Planned Public Uses and Assessment of their Impacts
Trail Network – Trails are established throughout the property and allow for hiking and nature
observation within the preserve (Figure 10). Firebreaks double as hiking trails to avoid altering
additional habitat. Trails are maintained and monitored to ensure that visitors stay on them and
no new trails are being made. Clearing the trails of fallen trees and debris and creating new trails
may also enable and increase the illegal use of all terrain vehicles (ATVs) and dirt bikes on the
property so monitoring will be necessary.
Easements, Concessions and Leases
An ingress/egress easement exists over Rivers Road, which extends through the preserve and
ends at a private residence at 1920 Rivers Road that is enclosed within the preserve boundaries
as an out-parcel. There are no current concessions or leases on the preserve property.
Parking / Handicap Facilities - No facilities exist on the preserve besides Rivers Road, a well-
maintained gravel easement road, which allows visitors to view the preserve from their vehicles
as they drive south towards the parking area. A small mowed parking area exists in the southwest
portion of the preserve. In the future, if funds allow, 1-2 handicap parking spaces will be created
and a hard packed or paved trail will lead to an accessible picnic area. An information kiosk
exists adjacent to the picnic area. Currently, the grass parking lot is mowed by the adjacent land
owner as a volunteer contribution on an as needed basis.
Fencing / Gates – Fencing along the northern and western portions of the preserve was installed
in 2015 to deter dumping, encroachment and illegal access. No other fencing needs are
anticipated.
3.5 Adjacent Land Uses
Single family homes exist to the north, east and west of the property, with one private residence
within the boundaries of the preserve as an out-parcel. A church encompassing several parcels
exists to the north and northeast of the property along with a parcel that contains remnants of a
small tree nursery. A conservation easement exists to the south of the property.
3.6 Prospective Land Acquisitions
There are currently no surrounding properties under consideration as prospects for acquisition.
The only parcel that was previously considered, was the outparcel in the center of the preserve
that is completely surrounded by preserve land. As of February 2013, it is owned by CSC
Equity, a Texas Limited Liability Company. This parcel was determined to not be a viable
purchase by the County due to the existing structure that exists on the property. Surrounding
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 29
undeveloped parcels can currently be donated to the program or nominated to the program for
acquisition if the program is approved to continue acquisition in the future.
3.7 Proposed Single - or Multiple - Use Management
Management of this parcel for public use will focus on maintenance of the trail, signage, kiosk
and picnic area (Table 8). All of the uses are restricted to those consistent with conservation of
plants, animals, any historical/archaeological features, and passive enjoyment of these resources
by visitors.

4.0 Future Use of the Rivers Road Preserve including Management Issues,
Goals and Objectives
This section describes the main management issues, goals, and objectives for Rivers Road
Preserve as well as the overall management framework. Central to the management of the
Preserve is the mission of the Conservation Collier Program, and the goals and objectives set
forth in this management plan.
4.1 Management Plan Framework
Each property purchased by Conservation Collier shall have its own management plan. At the
time the property was purchased, the Conservation Collier Ordinance required that an “Interim”
Management Plan be developed within 60 days of closing. Interim plans include basic items
such as removal of invasive exotics and trash, establishing site security, developing management
partnerships and planning for public access. The interim plan for this site was officially
approved in September 2011. The ordinance then requires a “Final” management plan be
developed within two years. Subsequently, the property management plan must be updated
every five years. Final management plans, however, are considered living documents and can be
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 30
updated at any time. Review of all management plans start in the Lands Evaluation and
Management Subcommittee and then must be approved by both the CCLAAC and the BCC.
4.1.1 Preserve Manager: Contact Information
The Site Manager for Rivers Road Preserve will be a designated Collier County
Environmental Specialist who can be contacted through electronic mail:
ConservationCollier@Colliergov.net.
4.1.2 Preserve Rules and Regulations
No dumping, use of unauthorized vehicles, or removal or destruction of any natural or
historical/archaeological resources shall be permitted within the preserve. The goal is to
allow limited, non-destructive public access to maintain natural resource habitat and
native plant communities and animal species.
4.2 Desired Future Conditions
This section includes a description of the proposed future condition for the site’s natural areas.
Management techniques to achieve these conditions are listed in the following sections.
After management goals are met, Rivers Road Preserve will consist of pine flatwoods, mixed
wetland hardwoods, cypress, wetland forested and freshwater marsh habitats. Several
outstanding examples of pop ash swamp will be present. The canopy will be comprised of
maple, pop ash, red bay, slash pine, laurel oak, cabbage palm, willow and cypress. The mid-
story will be maintained and continue to consist of scattered natives including: marlberry,
saltbush, American beautyberry, common button bush, sawgrass, dog fennel, dahoon holly,
gallberry, rusty lyonia, red mulberry, wax myrtle, wild coffee, myrsine, winged sumac, saw
palmetto, saffron plum and hog plum. Groundcover will remain native and will include: swamp
fern, habernaria, ludwigia, maidencane, passion flower, frog-fruit, pickerelweed, Bracken fern
sagittaria, blue porterweed, alligator flag, southern cattail and chain fern. Prescribed burns will
be conducted in the Pine Flatwoods areas on a 3-5 year cycle to reduce saw palmettos and keep
hardwoods and palm cover sparse (<25%), allowing for a diverse and dense herb layer.
Management of the preserve will also improve habitat for the non-listed wildlife species that
have been observed on the preserve and will make the habitat desirable for the listed species that
may be in the area of the preserve.

4.4 Goals and Objectives for 10 year period
A set of goals and objectives for the Rivers Road Preserve were developed in conjunction with
the drafting of this Management Plan. The goals and objectives in this plan are tailored
specifically for the Rivers Road Preserve, based on the purposes for which the lands were
acquired, the condition of the resources present, and management issues for the property. On-
site managers should be familiar with the entire Management Plan. Goals and objectives from
the interim management plan for the Rivers Road Preserve were reviewed to determine if they
remain meaningful and practical and if so, were carried over into this plan. The goals and
objectives presented here reflect programmatic goals and ideas of Conservation Collier personnel
in charge of managing and protecting the area. These goals shall not be modified, but specific
application of management techniques may take into consideration input by user groups and
other stakeholders from outside the program, accommodating user needs and desires where
practicable and where overarching management goals are not violated.
Management issues are discussed below in separate sections. Within each section, approaches
for dealing with these issues are described. The ability to implement the specific goals and
objectives identified in this plan is dependent upon the availability of funding resources. The
following goals have been identified for the Rivers Road Preserve:
Goal 1: Maintain High Quality Habitat with Limited Disturbance for the Benefit of Native Flora
and FaunaEliminate or Reduce Human Impacts
Goal 2: Remove and Manage Invasive, Exotic Plants
Goal 3: Monitoranage Wildlife
Goal 4: Create and Implement a Prescribed Fire Program
Goal 5: Continue to Restore Native Vegetation
Goal 6: Maintain Prepare Preserve for Public Access Trails and Amenities
Goal 7: Facilitate Uses of the Site for Educational Purposes
Goal 8: Provide a Plan for Disaster Preparedness
Goal 9: Coordinate with Stakeholders, Partners, and Regional Agencies
Goal 10: MonitorOpen the Preserve for Public Use
Goal 1: MAINTAIN HIGH QUALITY HABITAT WITH LIMITED DISTURBANCE FOR THE
BENEFIT OF NATIVE FLORA AND FAUNA
Action Item 1.1 Eliminate or Reduce Human Impacts
The preserve is currently easily accessible for dumping, use of off-road vehicles, and hunting. In
order to provide for the safety of those who will be lawfully using this site for passive recreation
and research, and to ensure that the programs of ecological preservation and restoration can take
place unabated, security measures have been put into place.
The property owner in the center of the preserve became an official Collier County volunteer in
2016 and since then has helped to keep watch over the preserve on a daily basis. He will call the
CCSO if assistance is needed.
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 32
Action Item 1.2: Removal of refuse and dilapidated structures
Although former property owners were required to remove trash prior to conveyance to
Conservation Collier, site visits revealed small pockets of trash in several areas. On the northern
portion of the preserve, there was evidence that a small structure may have been once used and
abandoned. Water piping and timber was piled up and nearby there was fencing and old
appliances near the property line. All debris has since been will be removed by a County
contractor.
Action Item 1.3: Prohibit unauthorized access to the preserve / Security management
Staff will continue to maintain the site as legally posted. “No Trespassing-Collier County” signs
will be posted every 500 feet or less and at every corner of the property. Conservation Collier
signs also exist in two locations, one on Rivers Road and one on Moulder Drive. The signs make
it clear that there is to be “no littering” and “no hunting” and “no unauthorized vehicles”.
Similar signs will be posted at the trailhead areas once constructed. This will fulfill the legal
posting requirement. If signs are removed or vandalized, they will be fixed and replaced as
needed. They may need to be stabilized with concrete if they continue to be removed.
Staff will continue to work with enforcement agencies such as the Collier County Sheriff’s
Department Agriculture Division and FFWCC to enforce trespassing by citizens on off-road
vehicles, poachers and litterers. A Property Owner’s agreement with the Collier County Sheriff’s
office (CCSO) has been implemented. This makes the CCSO aware that the preserve exists and
provides them with a preserve location and trail map. This allows them to seek out and arrest
individuals who may be engaging in illegal activities on the preserve. One warning will be given
by the Sheriff’s office officers, followed by arrest for repeat offenders. If anyone is caught
poaching on the property or in possession of a firearm, they will automatically be arrested and
taken to jail. Staff has received approval from the BCC to sign Sheriff’s Department affidavits
to press charges as needed. Staff will also continue to stay in contact with preserve neighbors for
trespassing updates. A fence was installed along the northern and westernmost portion of the
preserve. Fencing will be monitored on a regular basis to ensure that fencing is not disturbed and
that no trespassing or unauthorized activities are occurring. Staff will also consider installing an
electronic gate along Rivers Road that would automatically close each night at dusk if funding
allows.
Action Item 1.4: Identify locations of rare and listed native plant and animal species
The location of rare listed plant species will be identified using a global positioning system
(GPS) device and mapped to allow staff to monitor them. Public trails will be constructed to
avoid areas where rare and listed species exist. Actual and potential locations of resident animal
life will also be identified and documented and steps will be taken to construct visitor amenities
away from animal nesting sites.
Action Item 1.5: Inspect and Monitor Trailspublic access
Public access will be limited to special requests until initial exotics are removed and safe trails
can be created. Once the site is opened up for public access, vVisitors arewill be encouraged to
stay on established trails while hiking. Staff will frequent the site to will conduct bi-weekly to
monthly inspections of the public access areas to ensure no hazards are present. Horseback
riding is allowed on the trails. Well-mannered dogs will be allowed in the preserve on leash only.

Pick-up bags will be provided at trail heads. If problems start to occur, this privilege will no
longer be allowed.
Action Item 1.6: Enforce regulations prohibiting trash in or near the preserve
Staff will monitor the trails on a regular basis and if excessive dumping or littering start to occur,
enforcement actions will be sought through the County Sheriff’s Department. A garbage can is
currently available next to the parking area. A bear proof garbage can will be added before the
end of 2019 as a proactive measure.
Action Item 1.7: Discourage visitation to the park at night
A sign designating park hours as dawn to dusk will be installed at the entrance to the preserve
and adjacent landowners will be given an emergency phone number if they detect human activity
on the preserve after hours. If problems arise, the Collier County Sheriff’s Office will be
contacted to patrol the area and preserve on a routine basis.
Goal 2: Remove and Manage Invasive, Exotic Plants Removal and Management
Action Item 2.1: Map location of exotics
Exotics have been noted in several areas and sporadically throughout the preserve. Detailed
mapping of the location and type of exotics is necessary to determine the extent of each
population and for identifying the estimated method and cost of removal.
Action Item 2.2: Set up permanent photo points throughout the preserve
Identify locations for photo points throughout the preserve and record photo points with a GPS.
During photo documentations, one photo is taken in each of the cardinal directions (north, east,
south and west) and a 360-degree panoramic photo is taken. These photos will help to monitor
exotic removal and native plant recruitment over time. If necessary, more photo points will be
established to aid in management decision activities.
Action Item 2.3: Explore grants for exotic vegetation removal
Staff received notification in April 2014 from the USFWS, Partners for Fish and Wildlife
Program that a grant of $15,000 would be awarded specifically for exotic removal within the
preserve. In November 2014, an additional $15,000 from the Florida Fish and Wildlife
Conservation Commission’s Invasive Plant Management Section was awarded for further
treatment of invasive exotic plants on the preserve. Additional grants from will be pursued in the
future for continued maintenance of the exotic vegetation as appropriate.
Action Item 2.4 Monitor biological control beetle
project
The United States Department of Agriculture (USDA)-
Agricultural Research Service (ARS) selected the preserve
to be part of an Air potato beetle (Lilioceris cheni)
statewide release project. The beetles are a host-specific
specialist and only feed on air potato leaves. Five pairs of
the beetles were released on July 10th, 2013. An additional
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 34
100 beetles were released by USDA on the private property in the center of the preserve in
August 2014. Since the releases, a significant amount of biomass reductiondamage has been
observed on the Air potato plants in the general area each summer growing season
since.USDAsince. USDA-ARS and County staff will monitor the amount of damage the beetles
may inflict on the air potato plants over time. Permission to release this beetle was acquired
from USDA-APHIS after extensive testing demonstrated its host specificity with virtually no risk
to other plant species. If this bio-control program is successful, this could potentially save the
program money that otherwise would have been spent to treat the plants with herbicide.
Action Item 2.5: Treat Invasive Exotic Plants
The following invasive, exotic plants will require removal using the recommended methods.
Table 10: Invasive, Exotic Plant Species Control Plan for the Rivers Road Preserve
Scientific Name Common Name(s)Description and Recommended Control(s)

For seedlings and saplings: (1) hand pull, being sure not to
break plant off of root system and remove or place in piles
to help reduce the chance that they will re-root or; (2) Treat
with foliar, low volume spot application of 5% Rodeo. For
mature trees: (1) Fell large trees with chain saw leaving a
level surface, or fell small trees with machete and treat with
triclopyr or glyphosate products according to frill and girdle
directions on SLN. Use aquatic versions where standing
water is present. Monitor for resprouting and retreat as
necessary. (3) Mature trees are very difficult to control with
foliar applications.
Momordica charantia balsam pear A foliar application of Roundup at 1.5%

treatment with 50% Garlon 3A or 10% Garlon 4, or use a
basal bark treatment with 10% Garlon 4.
Urena lobata Caesar’s Weed
Hand pull seedlings, Foliar treatment with 2-5% glyphosate
in water can be sprayed on young plants. Its best to treat in
the spring or summer prior to seed maturation. Responds
aggressively to fire
Wedelia trilobata wedelia
Treat with a 2% solution of glyphosate while large, dense
populations may require a 5% solution. Follow-up
treatments should be conducted as needed. Triclopyr at 1-
2% is also effective.
Action Item 2.6: Remove, treat and monitor populations of invasive exotic plants
The control of invasive, exotic species is critical for the preservation of the natural communities
in the Rivers Road Preserve. Approved Collier County contractors will continue to be hired to
remove and treat the invasive exotic plants. These contractors will chemically treat in place or
cut and treat all shrub and tree-like species on the FLEPPC Category I or II list as well as
identified nuisance weedy species. Dense mono-cultures of Brazilian pepper along Rivers Road
were initially mechanically reduced to ground level and stumps were treated with herbicide.
Specific treatment methods should be done according to the recommended control column in
Table 10, unless new treatments are discovered that work well and do not cause non-target
damage. Extreme care should be used to avoid any non-target damage, near sensitive natives,
native seedlings and mature pine trees. The use of imazapyr containing herbicides should be
avoided on site. After initial removal and treatment, staff continues to ensure treatment areas are
inspected for re-sprouting and that new seedlings are treated as needed until maintenance state is
achieved. Once maintenance state is achieved, exotic maintenance will be done once a year and
will become a minimal expense.
Action Item 2.7: Establish long-term vegetation monitoring
Long-term management of the preserve should be based on biological data. Changes following
baseline conditions should be assessed as negative or positive, and management strategies
changed appropriately.
Goal 3: Monitor Wildlife Management
Action Item 3.1: Establish long-term wildlife monitoring
While some wildlife data has been collected, additional baseline data should also be collected,
especially on invertebrates, small mammals, reptiles, and amphibians. The site manager may
contract this work out or enlist the assistance of local educators to coordinate student research

projects. Wildlife and plant sampling, including bird surveys, should take place at regular
intervals (ca. 5-10 years) to detect long-term trends.
In 2018, the Conservation Collier program began to partner with the Fstop Foundation which is a
citizen scientist program. Their mission is to create awareness through the use of photography.
The program engages volunteers in producing data that helps show the importance of the Florida
Panther as an umbrella species. They have set up wildlife camera stations on three Conservation
Collier Preserves including the Rivers Road Preserve. The photos are shared with the program
and the Florida Fish and Wildlife Conservation Commission including the two photos below.
Fstop is a 501(c)3 and receive their funding from private donations and corporate matching
funds.
Action Item 3.2: Native wildlife species
management
Management of native animal species at the
Rivers Road Preserve should correspond with
the management goals of the pine flatwoods, mixed
wetland hardwoods, cypress, wetland forested
and freshwater marsh habitats. Maintenance of
viable populations of native animal species
should be conducted by implementing management measures that maintain the viability of the
natural habitat. The Rivers Road Preserve should be managed to provide adequate habitat for
listed species found on or near the site. Some management recommendations for state and
federally listed plant and animal species found on the preserve are listed below. General
management for all listed species would be consistent with general vegetation management
recommendations, exotic species control, and fire management.
Action Item 3.3: Problem wildlife species management
Indigenous and non-native vertebrate and invertebrate species may become pests under certain
conditions. Control of indigenous pest species is recommended if they interfere with
management goals. To date, evidence of wild hogs making wallows on the preserve has been
noted, but no actual hogs have been seen.
Action Item 3.4: Acquire services of licensed or qualified contractors for the removal of
invasive exotic or problematic animal species

Conservation Collier Program 37
Wild hogs have not been observed on the preserve, however, if they become a nuisance, they
may be trapped using pens with trap doors and baited with acorns or old corn. A contractor can
be hired to accomplish this if the need arises. Wild hogs may be hunted in other areas of the
County that are designated wildlife management areas however; hunting will be prohibited on
the preserve. Total exclusion of hogs is not usually possible; however, the amount of hog
damage will be monitored to determine the appropriate action needed.
If feral cat colonies are found near the preserve, the element that sustains an undesirable
population should be identified and efforts made to ask property owners to control (i.e. refuse
bins, dumpsters, and supplementary feeding by humans). Traps may also be set if other methods
are unsuccessful. A similar approach shall be taken to control feral dog populations, through
elimination of the elements that sustain their undesirable population.
Goal 4: Create and Implement a Prescribed Fire Program Management Plan
Fires were a naturally occurring event in native communities prior to mankind’s intervention.
The primary ecological functions of fire are to eliminate accumulated plant material, return
nutrients to the soil, and germinate fire-dependent species. In today’s preserve areas prescribed
burning is an essential tool in both land and wildlife management, and helps reduce potential
catastrophic wildfires that can occur in the wildland/urban interface areas. Proper prescribed
burns promote the growth of green shoots, roots, and rhizomes of grasses and sedges that are
then available for foraging. In wetlands, burning creates deep pools and edges for nesting and
feeding of waterfowl and controls undesirable vegetation.
Much of Collier County is comprised of natural communities that are dependent on fire to
maintain species composition and diversity. The use of prescribed fire as a management tool will
be critical to the long-term health of the natural communities and native species at the Rivers
Road Preserve.
Action Item 4.1: Create a Prescribed Fire Management Plan
Below is the prescribed fire management plan for Rivers Road Preserve. The preserve land
manager with assistance from the Florida Forest Service (FFS) and/or a Certified Prescribed
Burn Manager will implement the prescribed fire management plan according to the specific
needs of Rivers Road Preserve. Staff may coordinate this effort with other local qualified
agencies for review and approval.
Objectives
The prescribed fire plan for the Rivers Road Preserve will be a program that mimics the
natural fire cycle for the various natural community types identified within the preserve.
Timing, based on weather conditions and ignition practices can be modified to accomplish
goals ranging from exotic vegetation control to wildlife habitat enhancement and fuel
reduction within burn units. This prescribed fire management plan will be implemented at
Rivers Road Preserve for ecological purposes. The goals and objectives established for the
preserve will be clearly laid out and incorporated into each prescription. Generally,
prescribed burns conducted at the Rivers Road Preserve will involve a variety of firing
techniques over a range of weather conditions to create mosaic burn patterns that will benefit
an array of wildlife species.
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 38
Burn Units
The Preserve can be divided into smaller burn units. The creation of burn units not only
facilitates the application of prescribed fire, it will also help create a mixture of burned and
unburned areas across the preserve. Patches of unburned habitat in conjunction with newly
burned areas will increase habitat heterogeneity, ensuring a wide range of habitat
compositions year round for use by a diversity of wildlife species. The size and boundaries of
each burn unit should be established based on the preserve boundaries and the location of
existing barriers such as fence lines, ditches, roads and other existing structures. Fire breaks
will consist of primitive roads, trails disked to bare mineral soil, wet lines, and/or natural
vegetation breaks.
If new fire breaks are needed, efforts will be made to minimize disturbance to existing native
vegetation during their creation and maintenance, and no wetlands will be adversely
impacted as a result of fire break construction. In the event of a wildfire FFS may create fire
breaks within existing wetlands. If plow lines are put in as a result of a wildfire, whether
they are in a wetland or upland, efforts will be made to restore those areas to prior grade.
Burn Frequency and Burn Season
Historically the frequency of wildfire in Florida’s ecosystem varied from year to year. However,
fire frequency for natural communities as found within the Rivers Road Preserve will generally
follow these guidelines (FNAI 1990):
mesic pine flatwoods – frequent (2-4 year cycle);
wet pine flatwoods – frequent (3-7 year cycle);
depression marshes – more frequent around the periphery (3-7 year cycle) and
becoming more occasional toward the center (8-25 year cycle);
cypress/pine/cabbage palm – transitional community from moist upland to hydric
sites – occasional (8-25 year cycle);
upland mixed forest – rare or no fire; densely closed canopy limits air movement and
light penetration, making high humidity relatively constant.
Burn units incorporating multiple natural communities under different fire cycles will be
burned based on the community requiring the shortest cycle. The other communities within
that burn unit that are on a longer fire cycle will likely not burn as frequently since fuels will
not have built up. The seasonality, weather factors, or ignition techniques of the prescribed
burn will also be chosen to selectively burn the community within the unit with the shortest
fire cycle.
Fire maintenance of hydric hammocks will be accomplished primarily by burning the
adjacent flatwoods and marshes, reducing the fuel needed to ignite the hammock.
Maintenance of natural species composition and protection from excess fuel build-up will be
accomplished by allowing fire to enter the edges but not completely burn through the
hammocks. Fire will be introduced into the edges of hammocks under moist conditions that
will not result in a destructive fire through the hammock. Fire frequency in this situation will
be dictated by the frequency of fires in adjacent communities.
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 39
Fire will be applied to freshwater marshes in conjunction with the burning of surrounding
pine flatwoods to maintain open herbaceous ponds and control woody plants found primarily
on the edge of these depressions. The centers of depression marshes are much wetter than
the surrounding flatwoods and may not burn at the same time the flatwoods are ignited. In
this case, a separate fire under guarded conditions may be needed to carry the fire across the
marsh.
Qualitative observations will be made within each burn unit on an annual basis to determine
current fuel loads, habitat structure, and habitat quality. The burn schedule will then be
modified as needed based on these qualitative observations. Areas where fire cannot be
implemented will instead be mowed, roller chopped, or pruned to mimic effects of fire. The
burn manager will conduct post-burn inspections to ensure the burn objectives are being met
for each natural community. When possible, vegetation monitoring activities will be
conducted around burn events to help assess the effectiveness of the prescribed burn regime.
Burn Schedule
Generally, prescribed burns within the Rivers Road Preserve will be conducted during the
growing season (mid-March through early September) as well as during the dry season
(November to mid-May). Essentially, burns will be scheduled when conditions allow, and
the timing selected to best suit the objectives for each burn unit, as well as to provide
protection to listed species.
Burn Manager Duties
Florida Statute 590.125 and Chapter 5I-2 of the Florida Administrative Code (FAC) grant the
Florida Forest Service the authority to regulate prescribed burning in Florida. Prescribed
burning will be planned and carried out by a Certified Prescribed Burn Manager (as licensed
by the FFS) and experienced fire crews utilizing a Prescribed Burn Plan form, referred to
from here on as the prescription. The planning and application of prescribed burning will
comply with all applicable federal, state, and local regulations.
Each prescription will include the following at a minimum:
purpose for the burn;
brief description of the natural community type(s) to be burned;
a map depicting the location of the burn, firebreak locations, potential hazard areas
and escape routes for the fire crew;
acceptable ranges of weather and soil moisture conditions;
a pre-burn inspection of burn unit, firebreaks and any potential hazards (including
power transmission lines, active cattle grazing locations, and existing manmade
structures) within the burn unit;
names and contact information for neighbors, lease holders, local fire district and
other pertinent stakeholders to be contacted prior to ignition;
techniques used to ignite the controlled burn;
personnel, equipment and safety requirements;
personnel assignments and responsibilities; and
post-burn evaluation.
All necessary permits and authorizations will be obtained by the Certified Prescribed Burn
Manager before implementation of the burn. As part of each prescription, the burn manager
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 40
Figure 9. Rivers Road Firebreaks and Mechanical
Exotic Removal Map
will develop an emergency action plan that will include escape routes for all personnel and
actions to be taken in the event of unexpected weather changes or fire behavior.
Weather and Fuel Considerations
When developing recommendations for a prescribed burn, the Burn Manager will give
careful consideration to weather and fuel conditions including, but not limited to: wind,
relative humidity, temperature, rainfall and soil moisture, air mass stability and atmospheric
dispersion. It will be the responsibility of the Burn Manager to obtain current weather
forecasts from FFS, and other weather sources as necessary, prior to executing the prescribed
burn. Although preferred weather and fuel conditions may vary based on specific burn
objectives, Wade and Lundsford (1989) suggest the following as preferred conditions for
prescribed burns in southern forests:
6 to 20 mph persistent surface winds;
30 to 55 percent relative humidity;
temperatures above 80 degrees Fahrenheit are recommended when the primary
objective is to control undesirable species;
damp soil moistures;
slightly unstable or neutral airmass stability; and
KBDI of 0 to 600 dependent on burn objectives.
Smoke Management
Smoke management is an essential component of the burn prescription. The Burn Manager
will evaluate the potential impacts of each prescribed burn to smoke-sensitive areas located
within a 20-mile radius from the location of the burn by employing a Screening System, such
as recommended in Wade and Lundsford (1989). Based on definitions contained within the
state regulations, smoke sensitive areas are
areas within which smoke could have an
adverse impact for reasons of visibility,
health or human welfare (NRCS 2003).
Monitoring of the prescribed burn will
continue until smoke no longer presents a
potential hazard and there is no potential
for the fire to reignite and cause an
uncontrolled fire.
Post-Burn Evaluation
The purpose of the post-burn evaluation is
to ensure the objectives of the burn were
attained and gain information to be used in
future burns (Wade and Lundsford 1989).
The post-burn evaluation will be conducted
by the Burn Manager within one week
following the burn, as well as a second
evaluation after the first post-fire growing
season. Quantitative vegetation
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 41
monitoring, photo documentation and wildlife monitoring can be implemented to further aid
in determining if the objectives of each burn were met.
Action Item 4.2: Develop Burn Units
Burn units will need to be delineated for Rivers Road Preserve, as outlined in the prescribed
fire management plan above prior to the implementation of the plan.
Action Item 4.3:
Install Perimeter Fire Lines
Fire lines were installed utilizing best management practices to minimize impacts to mature
trees, natural communities and wildlife populations. Firebreaks will be disked or mulched
down to soil and mature pine trees will be avoided. They are approximately 15-20 feet wide
due to the amount of thick canopy adjacent to neighboring residences (Figure 9). Firebreaks
also double as hiking trails in several areas.
Action Item 4.4: Hold Pre-Fire Public Meetings and Notify Surrounding Community
Public meeting(s) will be held before each burn and a system of notifying neighboring
landowners in advance of prescribed burns will be established (via door postings, email,
phone trees, etc.) this system will be executed before each prescribed fire. A press release
will also be sent out to notify the newspaper, radio and news channels. Information will also
be provided to the County Manager, County Commissioners and local fire departments prior
to any burns.
The use of prescribed fire as a management tool will be critical to the long-term health of the
natural habitat and native species at the Rivers Road Preserve. Pine Flatwoods communities and
marshes require periodic fires. If pine flatwoods areas such as this go without fire for too many
years, fuels build up and wildfires can occur. The first controlled burn should be conducted in
the winter. The site should be burned in 3-5 year increments eventually moving towards burning
in the growing season. The County will work closely with the Florida Forest Service (FFS) to
conduct the first prescribed burn on the property. We will also work with the County Fire
Department to protect the surrounding structures and property.
Goal 5: Continue to Restoreation of Native Vegetation
Action Item 5.1: Encourage natural recruitment
In at least one area of the preserve where several old structures were removed, signs of natural
recruitment of pines, grasses and myrtle have been noted. Removal of exotics will further
encourage restoration. Further planting of pines may be considered in this area and due to the
proximity to the planned parking / picnic area and trailhead, may provide an opportunity for
educating visitors about restoration.
Action Item 5.2: Plant supplemental ground cover species
After a burn regime is established, vegetation monitoring will take place. If natural restoration
does not occur, supplemental ground cover species will be planted.
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 42
Action Item 5.3: Monitor and treat new invasive, exotic species that may occur post-fire
and in fire breaks to prevent them from hindering native recruitment and re-growth
After prescribed burns, any newly identified areas of invasive, exotics will be noted and a
treatment plan prepared.
Goal 6: Maintain Prepare Preserve for Public Access Trails and Amenities
Action Item 6.1: Develop an ADA accessible trail and parking area
A small grassy parking area was created at the end of Rivers Road in the short term to
accommodate a 5-10 vehicles. In the future, if funds allow, 1-2 handicapped parking spaces will
be built using crushed/hardened rock, shell or concrete and a trail will lead to the picnic area..
Action Item 6.2: MaintainDevelop a picnic area
A picnic area was created by a local Eagle Scout in 2014 under the pines adjacent to the planned
parking area. This area has a large picnic table and a bench. This area will be monitored for trash
and safety of amenities.
Action Item 6.3: Maintain Develop a trail system
After appropriate actions were taken to reduce or eliminate exotic vegetation, trails were
established throughout the property to allow for hiking and nature observation within the
preserve (Figure 10). The current hiking trails are approximately 1.76 miles long and wind
throughout the northern portion of the preserve, with trail heads near the future parking area and
adjacent to Rivers Road. Trails overlap with firebreaks in several areas. The first trailhead along
Rivers Road northeast of the parking area will leads into a trail that heads east and partially
follows a formerly cleared road adjacent to a power line corridor. The trail will then leads to the
north past a pond up into the northern portion of the preserve and gives hikers the option to hike
back down Rivers Road to the parking area or to loop back around and down to the pond the
same trail they started in on. All trails follow as closely as possible any areas that were disturbed
or cleared of exotics. This area originally had scattered Brazilian Pepper, some melalueca and
significant quantities of cabbage palm. There are several marshy areas that were avoided,
however, allowing the trail to come close to these areas for viewing was considered.
The second trailhead is located adjacent to the northwest of the parking / picnic area and directs
visitors in a loop through an area that was cleared of air potato and Brazilian pepper and follows
an old fire line. The USDA started a biological control program to reduce the prevalence of air
potato in this area. Trails may be marked with information regarding this program and the
results if successful.
Additional hiking trails are proposed to be approximately 0.45 miles long and may connect to
current trails on the eastern side of the preserve and may continue south into the pop ash marsh
area, with a potential boardwalk (approximately 600 feet long) constructed to allow viewing of
the marsh while prohibiting access. The boardwalk would be built only if future funding or grant
funding allows.
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 43
Once established, all trails will need to be maintained and monitored to ensure that visitors stay
on them and no new trails are being made. Clearing the trails of fallen trees and debris and
creating new trails may also enable and increase the illegal use of all terrain vehicles (ATVs) and
dirt bikes on the property. Local birding groups may frequent the preserve and County staff may
provide quarterly public tours of the site. Local schools may also use the site for nature based
field trips. Signs will be installed on the fire line to ask visitors to respect the privacy of adjacent
landowners where appropriate.
Goal 7: Facilitate Uses of the Site for Educational Purposes Opportunities
Action Item 7.1: Develop interpretive signage to educate preserve visitors
SOnce a trail system is complete, site specific signage will be developed to educate visitors on
plant and animal identification and ecosystem information. Plant identification signs have been
placed throughout the trail system. The kiosk near the parking area has information about
preserve flora and fauna and a large map of the trails. Additional educational signage may be
installed near the picnic area and other areas in the future if funding allows.
Action Item 7.2: Provide preserve brochures in rainproof box on site
A trail map or a brochure outlining the native plant communities and wildlife present at the
preserve will be created by County staff and kept in rainproof boxes attached to the kiosk near
the preserve entrance(s). These boxes will be inspected monthly by the Preserve Manager and
refilled as necessary.
Action Item 7.3: Coordinate with local groups to encourage site visitation
Staff may work within the Parks and Recreation Department to encourage visitation by summer
campers. Local Boy and Girl Scout Troop and local church groups were notified about the site
and were encouraged to assist in small projects on site such as building picnic tables, benches
and a kiosk. Birding groups will also be notified about birding opportunities on site.
Goal 8: Provide a Plan for Disaster Preparedness
The Conservation Collier Program has a plan in place to examine the preserve and future access
ways after storms. Essentially, this is a visit before a storm to secure the property and a visit
after the storm within 48 hours to assess damage (see Action Items 8.3 and 8.4). Collier County
has several vendors under contract for disaster debris removal.
Action Item 8.1: Establish pathway for emergency rescue crews to access
Creating pathways for fire and rescue will include maintaining fire breaks around the preserve.
Emergency medical technician and paramedic access may be accommodated via these fire breaks
or on at-grade stabilized pathways. They may use Rivers Road or Moulder Drive. Fire lines will
be maintained to allow for FFS to access areas of the property however, once controlled burns
are conducted the chances of a wildfire will be greatly reduced. Helicopter landing GPS
coordinates will be included in the final approved burn plan.
Action Item 8.2: Survey trees along the trail and the perimeter of the property annually
for damage
Staff will utilize the services of a certified arborist if needed to determine diseased, weak, or
damaged trees/limbs surrounding the trails and kiosks that should be removed for safety reasons
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 44
and prior to and following hurricane season. This activity is intended to reduce the risk of visitor
injury.
Action Item 8.3: Visit preserve within 48 hours after a storm event to assess damage
Staff will take photos of damage and fill out appropriate Collier County Risk Management
Department forms. If damage is extensive, the preserve will be closed until public safety hazards
are cleared.
Action Item 8.4: Promptly clear storm debris from preserve
If necessary, a Collier County emergency debris removal contractor will be contracted as soon as
possible after the storm to schedule clean-up. Removal of debris and damaged or downed trees
along the trail system may be needed. Downed trees and limbs that do not appear to be a public
safety hazard will be cleared at the discretion of the Preserve Manager. As much of the
hurricane debris as possible may be chipped and retained on-site to be used as mulch for the trail
system.
Goal 9: Coordinate with Stakeholder, Partners and Regional AgenciesCoordination
Action Item 9.1: Coordinate with and notify stakeholders
Notify surrounding property owners, including adjacent public schools, churches, and interested
community members of the plans for the preserve and receive input on the final management
plan revisions every 10 years starting in September 2024.
Action Item 9.2: Interagency Agreements and Cooperating Agencies
An interagency agreement may be formed between two or more agencies that frequently assist
each other in performing prescribed burning activities. The Florida Forest Service may also
require the County to sign an interagency agreement if required before they can offer assistance.
Action Item 9.3: Cooperating Agencies
Coordinate with the following as appropriate:
Florida Audubon Society-bird watching opportunities
Florida Forestry Service-prescribed burning assistance
Collier County Fire Department-prescribed burning assistance
Collier County Sheriff’s Office-patrolling and enforcement
Action Item 9.4: Potential Cooperating Organizations
Coordinate with the following as appropriate:
Naples Chapter of the Florida Native Plant Society
Local Boy and Girl Scout Troops
Other community groups to assist with trail maintenance and other similar projects
Rivers Road Preserve Land Management Plan 5-year update Draft
Conservation Collier Program 45
Goal 10: Monitor Public UseOfficially Open the Preserve for Public Access
Action Item 10.1: Onsite grand opening ceremony
On May 2016, an onsite grand opening ceremony was held to commemorate the opening of the
preserve. The Chair of the CCLAAC, the program director and the preserve manager spoke and
a ribbon was cut at the trailhead. Neighbors of the preserve and the Parks and Recreation
Assistant Director attended, and attendees were led on a guided hike.
Action Item 10.2: Monitor Trails and Picnic Areas
Staff will visit the preserve on a bi-monthly basis to check the hiking trails and picnic area. The
picnic area will be monitored for weeds and trash.
Action Item 10.3 Recruit Volunteers
Staff currently works with the landowner who lives in the center of the preserve. He has become
a Collier County Parks and Recreation volunteer. He monitors public use as he enters and
leaves his property on a daily basis. He is in close contact with staff and informs us if there are
any concerns or issues. He also has two wildlife cameras set up at the entrance to his driveway,
so he can monitor potential trespassers and wildlife. He also mows the parking area on an as
needed basis and maintains the entrance road.
The preserve has been utilized by horseback riders as tracks and horse dropping are frequently
found on the trail and Rivers Road. Staff may attempt to recruit local horseback riders and/or
equestrian groups to volunteer to clean up the trails and to trim overhanging branches.
Local college students need to complete volunteer hours each year. When they approach the
program to volunteer, staff may utilize them to assist with trail maintenance or other projects at
the Preserve.

4.5. Establish an Operational Plan for the Rivers Road Preserve
This section provides management recommendations for operation of the Rivers Road Preserve.
It discusses maintenance and budgeting needs, the possibilities for contracting the restoration
activities, coordination, and other management issues.
4.5.1 Maintenance
The primary maintenance activities for the preserve will include the control of dumping and
littering within and around the preserve and trail. Other preliminary maintenance activities for
the preserve will include invasive exotic species control and trail maintenance.creation. Once the
preserve is open to the public other significant maintenance activities will be necessary for the
upkeep of all amenities and signage including but not limited to the trailhead/parking areas and
interpretive signage.
4.5.2 Estimated Annual Costs and Funding Sources
Preliminary budget estimates for Rivers Road Preserve include cost breakdowns associated with
resource restoration and management. The funding source identified for the restoration and
management activities is the Conservation Collier Program Management Trust Fund. Table 11
shows the activities planned for the next ten years and the initial and annual cost estimate of each
activity. This budget was developed using data from Conservation Collier and other cooperating
entities, and is based on actual costs for land management activities and maintenance. The
budget considers available funding and is consistent with the direction necessary to achieve the
goals and objectives for Rivers Road Preserve. The costs provided in Table 11 are based on
actual costs over the last 5 years and estimated costs for upcoming years. best available
knowledge, are subject to change and many could not be given at this time.
While reviewing the budget table, please note that staff received notification in April 2014 from
the USFWS, Partners for Fish and Wildlife Program that a grant of $15,000 would be awarded
specifically for exotic removal within the preserve. In November 2014, the program received an
additional $15,000 from the Florida Wildlife Conservation Commission Invasive Plant
Management Section to treat invasive exotic plants. This saved the program this amount of
money in those particular fiscal years. Additional grants will continue to bealso be sought to
supplement existing management funds on an as needed basis. Staff may also utilize the Collier
County Sheriff’s Department weekenders program for certain labor projects and may also
separately involve the County Scout programs for trail and amenity creation and enhancement.
Private conservation organizations may also provide funding for specific projects.
