EXECUTIVE SUMMARY
Recommendation to approve a Final Management Plan for the Gordon River Greenway Preserve
under the Conservation Collier Land Acquisition Program and direct the County Manager, or his
designee, to implement the plan.
OBJECTIVE: To obtain approval from the Board of County Commissioners (Board) of the Final
Management Plan (FMP) for the Gordon River Greenway Preserve under the Conservation
Collier Program and provide direction to the County Manager, or his designee, for its
implementation.
CONSIDERATIONS: The Conservation Collier Ordinance, 2002-63, as amended, Section
14(1), requires that a FMP shall be submitted by County staff to the Conservation Collier Land
Acquisition Advisory Committee (CCLAAC) for approval. Upon approval, the Plan shall be
submitted to the Board for final approval and shall be implemented according to the Board's
direction.
The Gordon River Preserve was purchased by Collier County on April 7, 2006 using funds from
the Conservation Collier Program. The property is located on the east and west side of the
Gordon River, approximately Y, mile south of the Golden Gate Parkway and just northwest of
the Naples Airport, within Section 34, Township 49S. Range 25E (Exhibit A),
The Interim Management Plan was initially approved by the Board in July, 2006 and then
revised and extended in 2009. A FMP was delayed while Conservation Collier worked with the
Parks and Recreation Department to develop a Gordon River Greenway Park that would include
this preserve,
Initially it was thought that one management plan could be developed for the entire Greenway
Park, However, Parks received a grant for acquisition of their section from the Florida
Communities Trust (FCT), which requires review and approval by FCT for any management
plans. Conservation Collier does not have this requirement and decided to develop its own plan
so that oversight of management and any future plan amendments/changes could be
accomplished pursuant to the Conservation Collier ordinance and with approval of the Board,
without needing additional review and approval from FCT.
This plan will balance resource restoration and protection with natural resource-based
recreational and educational use consistent with overall plans for the Gordon River Greenway
Park, A public meeting was conducted with surrounding neighbors in March 2011 in conjunction
with the Gordon River Greenway rezone process.
This FMP was reviewed and recommended by the Lands Evaluation and Management
Subcommittee of the CCLAAC on April 22, 2011 with minor revisions and then reviewed and
recommended by the CCLAAC on May 9, 2011. Both were publicly noticed meetings.
-
FISCAL IMPACT: Ongoing land management activity costs are estimated at approximately
$12,000 annually, once initial construction and exotic removals are completed. Funds are
budgeted within the Conservation Collier Land Management Fund to accomplish necessary
management activities,
Packet Page -1317-
6/28/2011 Item 16.E.7.
LEGAL CONSIDERATIONS: The Conservation Collier Ordinance (2002-63), as amended, in
Section 14, provides a legal framework for development of management plans and for use of
environmentally sensitive lands. The recommendation of the Gordon River Greenway Preserve
FMP by the Conservation Collier land Acquisition Advisory Committee for Board approval falls
within this legal framework. The FMP is legally sufficient for Board action. This action requires a
majority vote. - STW
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.
RECOMMENDATION: That the Board of County Commissioners approves the attached FMP
and directs the County Manager, or his designee, to implement it for the Gordon River
Greenway Preserve.

Gordon River GrcCln.vav Presen!e Land Management Plan
1.0 Introduction
The Gordon River Greenway Preserve is a 43.54-acre natural area within the boundary of an
unincorporated area of Collier County, Florida, within is directly adjacent to the City of Naples.
Native plant communities within the preserve include mangrove swamp, scrubby t1atwoods,
hardwood/coniferous/palm mixed, and mixed wetland hardwoods. The preserve is one part of
the larger "Gordon River Greenway Project". which, when complete, will be a 2-mile ecological
and trail corridor centrally locatcd within the Naples-Collier urban area. The Gordon River
Greenway Preserve and the Gordon River Greenway Park, directly to the north, are being
designed, permitted, and constructed together as one County project. Public amenity features
along the boardwalk will be consistent throughout the entire project. Certain aspects of the trail
system, such as trail width, security lighting, and hours of operation will be determined by
County officials, with input from the Conservation Collier Program, to ensure public safety and
consistency throughout the project area.
A site assessment to determine compliance with Conservation Collier's initial screening criteria
was conducted in May 2004 and the Conservation Collier Program purchased the property on
April 7, 2006. The County holds a fee simple title to the Gordon River Greenway Preserve. The
Conservation Collier program manages these lands under authority granted by Conservation
Collier Ordinance 2002-63 as amended (2007-65; available from www.municode.com).lnitial
acquisition activities are summarized in Table I.

Conservation. restoration and natural rcsource-based recreation are the designated uses of this
preserve. Management activities allowed include those necessary to preserve, restore, secure and
maintain this environmentally sensitive land for the benefit of present and future generations.
Public use of the site must be consistent with these management goals.
This is the Final Management Plan for the Gordon Rivcr Greenway Preserve. This 10-year
management plan will be submitted to the Collier County Board of County Commissioners
(BCC) for its approval. When approved, this plan will replace the Interim Management Plan.
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 thc November 2006 ballot rcferendum. Both voter-approved
referendums enable the program to acquire. preservc. restore, and maintain vital and significant
threatened natural lands, forest, upland and wetland communities located in Collier County,
Florida (Ordinance 2002-63, as amended). Propertics 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 Land Acquisition Advisory
Committee 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 BCC
established the Conservation Collier Program to a lands. As such, Conservation Collier holds
management authority for the Gordon River Greenway Preserve.
1.2 Purpose and Scope of Plan
The purpose of the plan is to provide management direction for Gordon River Greenway
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 the ten-year plan by identifying the appropriate management techniques
necessary to restore and preserve the resource.
This plan will balance resource restoration and protection with natural resource-based
recreational and educational use while looking at restoration needs, listed species protection and
maintenance of the site free of invasive, exotic plant and animal species. This plan is divided
into sections that incorporate an introduction, descriptions of the natural and cultural resources,
projected uses of the property, management issues, and goals and objectives.
1.3 Location of the Gordon River Greenway Preserve
Gordon River Greenway Preserve is located on the east and west side of the Gordon River,
approximately 1'2 mile south of Golden Gate Parkway and just northwest of the Naples Airport,
with the northern access to the Preserve being from Bembury Drive. (Figures I and 2). The
Gordon River Greenway Preserve is in southwest Collier County in Section 34, Township 49,
and Range 25.

1.4 Regional Significance of the Gordon River Greenway Preserve
Ecosystem services such as the protection of water resources, flood control, maintenance of
nutrient cycles, preservation of biological diversity, carbon sequestration, and the availability of
recreational lands are imperative for the well-being of the citizens of Collier County and may be
achieved through the preservation of natural areas. As of April 2008, approximately 66% (over
860,000 acres) of all lands in Collier County were protected in conservation areas (Figure 3) and
managed by private, local, state and federal agencies (FNAI 2008). Collier County's
Conservation Collier Program manages the 43.S4-acre Gordon River Greenway Preserve; it
contains mangrove swamp, scrubby flatwoods, hardwood/coniferous/palm mixed, and mixed
wetland hardwoods communities, Specific infonnation on the plant communities found on the
Gordon River Greenway Preserve may be found in section 2.3 (Natural Plant Communities) of
this document.

1.6 Public Involvement
Neighborhood involvement will be sought through public meetings associated with the rezone
and development process of the County's portion of the Gordon River Greenway, which includes
the Gordon River Greenway Preserve and the Gordon River Greenway Park adjacent to the
Preserve on the northern boundary. Staff will seek to coordinate management actions, such as
exotic removal with owners of adjoining lands that are also part of the larger Gordon River
Greenway Project.
Staff will continue to work together with Collier County Parks and Rec., Southwest Florida Land
Preservation Trust, the Naples Airport Authority, and the City of Naples to ensure that sufficient
public input is gathered regarding the Greenway and to ensure that Greenway development is
consistent across agency boundaries.
2.0 Natural Resources
2.1 Physiography
Gordon River Greenway Preserve lies within the Floridian section of the Coastal Plain. The
Coastal Plain extends from New Jersey to Texas and was fonned mainly from sedimentary rocks
deposited in marine environments (USGS 2(04).
2.1.1 Soils
Soils data is based on the Soil Survey of Collier County Area, Florida (USDA/NRCS, 1990).
The majority of the mapped soils on this parcel are Durbin and Wulfert Mucks, which are
frequently flooded hydric, tidal soils. Non-hydric, Immokalee Fine Sand is found in a very small
section at the northern edge of the property. (Figure 5).
Durbin and Wulfert Mucks, frequently flooded, covers approximately 91.3% of the preserve.
These level, very poorly drained soils are in tidal mangrove swamps. Mapped areas can consist
entirely of the Durbin soil, entirely of the Wulfert soil, or any combination of the two soils. The
penneability of both soil t)pes is rapid. The available water capacity in the Durbin soil is high
and in the Wulfert soil it is moderate. The water table fluctuates with the tide, and it is within a
depth of 12 inches for most of the year. The soil is subject to tidal !looding. The natural
vegetation consists of red mangrove (Rhi~ophora manglc), black mangrove (Aviccnnia
gcrminans), and white mangrove (LagllnclIlaria raccll1osa) (Liudahl et al. 1990).
Immokalee Fine Sand (7.6% of the preserve) is a nearly level, poorly drained, non-hydric soil
found on flatwoods. The penneability of this soil is moderate. The available water capacity is
low. The seasonal high water table is normally at a depth of 6 to 18 inches for 1-6 monthes
during most years; during the other months, the water table is below a depth of l8 inches, and it
recedes to a depth of more than 40 inches during extended dry periods. Natural vegetation
within this soil consists of Florida slash pine (Pinus clliottii), saw palmetto (Scrcnoa rcpens),
wax myrtle (Mvrica cerifera). chalky bluestem (Andropogon virginiells), little bluestem
(Schizachyri1lm -'copari1lm), and wiregrass (Arislida slricta) (Liudahl et al. 1990).
Hallandale Fine Sand and Urban Land - Immokalee - Oldsmar, Limestone Substratum Complex
soils cover 0.9% and 02% of the preserve respectively.

2.1.2 Hydrology/Water Management
Near the surface, the aquifer is highly permeable and the groundwater flows toward the west.
However, permeability decreases downward from a porous limestone into poorly indurated
sandstone cemented by micrite. The aquifer grades from freshwater downward into brackish
water due to the proximity of the Gulf of Mexico to the west and the brackish water in the
intermediate aquifer made primarily of Miocene aged sediments. Below that, the Hawthorne
formation typically marks the upper boundary of the Floridian aquifer, which is contained within
the underlying Oligocene age Suwannee Limestone (Lodge 2005).
A large majority of the preserve contains tidally influenced brackish water wetlands that hold
water year round.
The Surficial Aquifer is an aquifer close to the surface and unconfined, typically associated with
the groundwater table. This aquifer is generally limited to smaller uses such as household or
small agricultural uses. The Lower Tamiami aquifer is below this aquifer and is recognized as
being useful for long-term water needs. According to the South Florida Water Management
District's (SFWMD) technical publication 95-02 (Fairbank & Hohner 1995), the Surficial
Aquifer recharge capacity on the Gordon River Greenway Preserve is moderate at 43 to 56
inches annually. The Lower Tamiami Aquifer recharge capacity on the preserve is relatively low
at 7 to 14 inches annually.
2.2 Climate
The Gordon River Greenway Preserve is located in an area of Florida where humid subtropical
and tropical savanna climatic patterns overlap, with temperatures moderated by winds from the
Gulf of Mexico and the Atlantic Ocean. Sharply delineated wet and dry seasons and average
monthly temperatures greater than 640 Fahrenheit characterize a tropical savanna climate.
Monthly rainfalls may exceed tcn inches during the wet season. On the other hand, humid
subtropical climates typically show less extreme rainfall fluctuations between wet and dry
seasons and average monthly temperatures is less than 640 Fahrenheit in some months.
The average annual temperature for the coastal portion of Collier County is approximately 750
Fahrenheit. The warmest months are usually July and August. The humidity is high during
these months but frequent afternoon thunderstorn1s prevent excessively high temperatures.
Two-thirds of the annual rainfall occurs in the wet season from May to October. Thunderstonns
are frequent during the wet season, oecuning every two out of three days between June and
September. Rainfall records for the area indicatc that there is not significant variation in the
annual rainfall throughout much of the county: however, large variations often occur during a
single year. The Atlantic hunicane 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 tloristic species that form the natural vegetation of any
place. In addition to anthropogenic influences, 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 tbere. The

description or classifications of these floral communities differ by agency and are based on an
agency's goals and objectives for identifying plant communities. As some categorizations are
broad (e.g., forest) while others are specific (e.g., mesic pine t1atwoods), determining how each
organization classifies a community may be difficult. The South Florida Vegetation
Classification Scheme Crosswalks (Gilbert 2005) provides a way to decipher the classifications
of plant communities across agencies. Appendix 2 provides the categorization of the plant
communities observed on the Gordon River Greenway Preserve based on the South Florida
Vegetation Classification Scheme Crosswalks; classifications from the Florida Natural Areas
Inventory (FNAI) are also included in this appendix. Specific information on the invasive, exotic
species present on the preserve is provided in section 2.6.1 of this document.
The Florida Department of Transportation and Water Management Districts' Land Use, Land
Cover Classification System (FLUCCS) codes for plant communities observed on the Gordon
River Greenway Preserve are presented in Table 3. The following subsections (2.3.1, 2.3.2,
2.3.3 and 2.3.4) provide information about the plant communities observed on the preserve.

2.3.1 Wetlands: Mangrove Swamp - Disturbed
This land cover occupies 77% of the Greenway Preserve. Vegetation present in the wetland
canopy includes Australian pine (Casuarina sp.), red mangrove, black mangrove, white
mangrove, buttonwood (Conocarpus erectus), and cabbage palm (Sabal palmetto). A sub-
canopy is present along the edges of this wetland and is comprised of Brazilian pepper (Schinus
terebinthifolia), seagrape (Coccoloba uvifera), and wild lime (Zanthoxylum fagara). Species
found in the herbaceous stratum include crinum lily (Crinum americanwn), swamp fern
(Blechnum serrulatum), giant leather fern (Acrostichum danaeifolium), golden leather fern
(Acrostichum aureum), oyster plant (Tradescantia spathacea), scorpion's tail (Heliotropiwn
angiospermum), seashore paspalum (Paspalum vaginatum), pinel and heliotrope (Heliotropium
polyphyllwn) and grapevine (Vilis rotundifiJiia).
2.3.2 Wetlands: Mixed Wetland Hardwoods - Disturbed
The canopy along the edge of this community is comprised of laurel oak (Quercus laurifolia),
slash pine, Australian pine, cabbage palm, and melaleuca (Melaleuca quinquenervia). Red
mangrove, black mangrove, buttonwood, and white mangrove comprise the other canopy species
in the mid-zone of this wetland. The sub-canopy consists of Brazilian pepper, gumbo limbo
(Bursera simaruba), wax myrtle (Myrica cerifera), downy rose myrtle (Rhodomyrtus
tomentosa), white indigoberry (Randia aculeate), Spanish stopper (Eugeniafoetida), shoe button
ardisia (Ardisia elliptical, and Iyonia (Lyonia liguslrina). The herbaceous stratum contains
sawgrass (Cladium jamaicense), black needlerush (Juncus romerianus), swamp fern, golden
leather fern, and giant leather fern.
2.3.3 Uplands: Other Shrubs and Brush (Scrubby Flatwoods - Disturbed)
This area, labeled 3279 on Figure 6, is located on the north-central portion of the property, west
of the Golden Gate Canal and Bear's Paw Golf Club. This upland area has become infested with
dense downy rose myrtle. The dominant vegetation is saw palmetto, slash pine, wire grass and
downy rose myrtle.
2.3.4 Uplands: Hardwood/Coniferous/Palm Mix
This native area is located at the southwestern comer of the property and consists of cabbage
palm, slash pine, swamp fern, carrotwood (eupaniopsis anacardioides), Brazilian pepper, and
Australian pine.
2.3.5 Uplands: Spoil Area
A spoil berm exists on the southeastern parcel and it is most likely a result of the dredging of the
Golden Gate Canal. This spoil area supports bahia grasses (Paspalum nOlatum), cabbage palm,
Brazilian pepper, and several other upland species that have exploited the high ground within the
mangrove swamps. The soil is classified as Urban Land-Immokalee-Oldsmar-Limestone
substratum which is an upland soil according to the Soil Survey of Collier County, Florida
(1998).

2.4 Native Plant and Animal Species
This section discusses the flora and fauna found within the plant communities described above.
The next section (2.5) discusses all listed species in greater detail.
2.4.1 Plaltt Species
To date, 168 plant species have been recorded on the preserve (Appendix 3). Mike Kirby, Entrix
staff member, conducted a floristic inventory in 2009. Of these 168 species, 111 (66%) are
native - of which, 10 are listed by the State of Florida (3 are listed as endangered; 7 are listed as
threatened). A qualified botanist will conduct another floristic inventory after initial removal of
thick invasive, exotic vegetation.
2.4.2 Animal Species
Due to the dearth of specific surveys for the occurrence of animal species (in contrast to plants)
and the lack of on-site staffing, little is recorded for actual occurrences of animals at the Gordon
River Greenway Preserve. Occurrences of fauna at the preserve are based on direct visual and
aural observations or observed evidence of activity such as spoor, scat, or burrows by County
staff and environmental consultants during site visits. Occurrences are also based on site
information available in documents such as the site's initial criteria screening report, the
property's interim management plan and anecdotal information from persons with knowledge of
the site. Table 4 provides a comprehensive list of animals. both native and non-native, recorded
on the Gordon River Greenway Preserve thus far.

The Florida Breeding Bird Atlas (FWC 2003) lists 50 avian species that have been recorded as
confirmed, probable, or possible breeding in the vicinity of the site (Table 5). 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 Gordon River Greenway Preserve.
Other wildlife species that have not yet been recorded undoubtedly occur at the Gordon River
Greenway Preserve. During migration periods, transient bird species would be expected to
utilize this area for short periods of time. The developed character of the adjacent areas may
inhibit transient use by many mammal, reptile, and amphibian species, thus limiting the
utilization of the preserve to resident individuals or inhibiting the dispersal of many species to
and from the preserve.

2.5 Listed Species
Official lists of rare and endangered species are produced at the federal level by the United States
Fish and Wildlife Service and the National Marine Fisheries Service and at the State level by the
Florida Fish and Wildlife Conservation Commission (FWC) and the Florida Department of
Agriculture and Consumer Services. FNAl produces a list of rare and endangered species, and
maintains a database of occurrences of these species in Florida. The Institute for Regional
Conservation (IRC) also ranks native plant species by conservation status in the 10-county area
of South Florida. The following subsections (2.5.1 and 2.5.2) discuss the listed, rare and
protected plant and animal species found within and close to the Gordon River Greenway
Preserve in detail.
2.5.1 Listed Plant Species
The Florida State Statute titled "Preservation of native flora of Florida" (Statute 581.185)
provides the following definitions:
o Endangered plants means species of plants native to the state that are in imminent
danger of extinction within the state, the survival of which is unlikely if the causes of a
decline in the number of plants continue, and includes all species detennined to be
endangered or threatened pursuant to the federal Endangered Species Act of 1973. as
amended, Pub. L. No. 93-205 (87 Stat 884).
o Threatened plants means species native to the state that are in rapid decline in the
number of plants within the state, but which have not so decreased in such number as to
cause them to be endangered.
o Commercially exploited plants means species native to the state, which are subject to
being removed in significant numbers from native habitats in the state and sold or
transported for sale.
There are ten (10) plant species at Gordon River Greenway Preserve that are listed by the Florida
Department of Agriculture and Consumer Services (FDACS), three (3) as endangered and seven
(7) as threatened (Table 6). A brief description of these species and their status is included in the
following paragraphs.

Three of the ten listed plant species found on the Gordon River Greenway Preserve are classified
as bromeliads. Bromeliads are members of the pineapple family (Bromeliaceae). While some of

these species may be found growing terrestrially. most native bromeliads found in Florida are
found growing attached to tree trunks and branches and may therefore be referred to as epiphytes
(a plant that lives upon other plants; from Greek "epi" = upon "phyte" = plant). The leaves
and/or roots of these airplants (depending on the species) absorb the water and nutrients they
need from the air and from the rain that falls through the canopy of the tree on which they are
found. Since epiphytes use their roots only to anchor themselves to another plant, they are
considered non-parasitic. Even though the three listed bromeliad species found on the Gordon
River Greenway Preserve are fairly common in the state, they are listed due to illegal collecting
and the destruction of the habitats in which they are found. Additionally, infestation by the
introduced Mexican bromeliad weevil (Metamasius callizona) has been implicated in the decline
of many airplant populations around the state. Currently, there are no control measures in place
however, close research and monitoring is taking place.
Stiff-leaved Wild Pine (Tillandsia fasciculata), is
also known as cardinal airplant and common wild
pine. T. fasciculata is listed as an endangered plant by
the State of Florida and has been in 24 counties
throughout Florida (Wunderlin & Hansen 2008). This
epiphyte was frequently found in South Florida before
the introduction of the Mexican bromeliad weevil.
Today, it may be found in hammocks, cypress swamps
and pinelands.

Like most of the other bromeliads in Florida, this species is often
referred to as a "tank" bromeliad because the leafaxils and
central stems form a "tank" or reservoir at the base of the plant.
These reservoirs capture and hold water, dead and decaying
plant matter (leaves, seeds twigs, etc.), and dead and drowning
non-aquatic insects; these trapped items provide nutrients for the
plant (Larson et al. 2006).

Twisted airplant (Tillandsia jlexuo.~a) is a slow growing epiphyte
found in moist forests and swamps. T flexuosa, also known as
banded wild pine is listed as a threatened plant by the State of Florida.

Although seemingly common, this majestic tree is
considered endangered by the State of Florida. Native to the
cypress swamps of South Florida and found growing
naturally in only 4 counties within the state (Wunderlin &
Hansen 2008), this tree is a favorite landscape tree
throughout Florida.

FNAI maintains a database of occurrenccs of rare. threatened, and endangered specics in Florida.
An element is 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 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.
These element occurrence data are built into biodiversity matrices. Each matrix encompasses
one square mile and includes all species and natural communities tracked by FNAI, including all
federal listed species. The FNAI report for tbe matrix in wbicb tbe Gordon River Greenway
Preserve is located identifies one likely element and eleven potential clements. Of these twelve
likely and potentia] elements, one has been observed on tbe preserve, namely Florida royal palm

Eastern Indigo Snake (Drymarchon corais couper!)
The Eastern indigo snake, a State and federally listed Threatened species, uses a wide variety of
habitats in peninsular Florida and may be expected to occupy almost any tract that contains
potentially suitable habitat. Typically, within this area of South Florida, the Eastern indigo snake
is found in scrubby and pine t1atwoods areas with groundcover consisting of palmetto near
water, or tropical hammocks, and frequently uses gopher tortoise burrows as refuges. Based on
current site characteristics, the amount of suitable habitat, and the population of gopher tortoises
present on and adjacent to the site, the probability of Eastern indigo snake occurring on the
preserve is high. Increasingly, the United States Fish and Wildlife Service (USFWS) requests
implementation of Standard Protection Measures for the Eastern Indigo Snake to minimize
potential impacts to the snakes during site clearing and construction. Typically, these measures
include education of heavy equipment operators to identify and avoid Eastern indigo snakes,
requirements that all work stop if an eastem indigo snake is observed, and having an on-call
biologist to oversee the construction in potentially suitable habitat.

Gopher Tortoise (Gopherus polyphemus)
The gopher tortoise is a state-listed Threatened species that occupies a variety of open, upland
habitat characterized by well-drained, sandy soils, some of which are found within the northern
upland area of the Gordon River Greenway Preserve. At the request of Collier County and in
preparation of planning the park's future layout, ENTRIX ecologists conducted a 100-percent
survey (March-April 2008) of the project area to determine the presence of this species.
Evidence of gopher tortoises was observed in the scrubby f1atwoods wi >50% downy rose myrtle
(FLUCFCS 3272). A total of I active bUITOW, 3 inactive burrows, and 9 abandoned burrows
were documented by ENTRIX ecologists within the Gordon River Greenway Preserve. Fewer
than 5 gopher tortoises may need to be relocated from the parking area near the Naples Zoo
within the Gordon River Greenway Park. If possible, these gopher tortoises will be re-Iocated to
the 3.9 acres of disturbed Scrubby Flatwoods plant community within the Greenway Preserve,
once this area is restored. Staff will coordinate relocation with FWC and Parks and Recreation
staff.
Brown Pelican (Pelecanus occidelttalis)
The Brown Pelican is a state-listed Species of Special Concern that requires coastal, mangrove
islands for breeding and open saltwater areas for foraging. Limited suitable nesting habitat was
observed within the Gordon River Greenway Preserve within a small mangrove island currently
used as a rookery site by yellow-crowned night herons (Nvctanassa "iolaeea). Extensive
foraging opportunities exist within the Gordon River and the Golden Gate Canal.

Little Blue Heron (Egretta caerulea)
Snowy Egret (Egretta thula)

Reddish Egret (Egretta ru[cscens)
With the exception of the state and federally endangered wood stork, all of the birds listed above
are Florida Species of Special Concern. During the extensive fieldwork conducted by ENTRIX
ecologists as part of this project, several listed and non-listed wading birds were observed
foraging within the exposed and mangrove-dominated shorelines along the Gordon River and
Golden Gate Canal. No nesting by listed wading birds were observed, but a small rookery of
non-listed yellow-crowned night herons was observed. A review of the FWC online waterbird
nesting database, revealed that only one wading bird colony was located within five (5) miles of
the project boundary, and this colony has been inactive during the past decade. It is unlikely that
nesting by any listed wading bird might occur elsewhere on the project site within the mangrove-
dominated wetlands along Gordon River. The project boundary, however. is within the 18.6-mile
core foraging area (CF A) of some of the most sil,'l1ificant Wood Stork nesting colonies in
southwest Florida; especially those at Corkscrew Swamp Sanctuary (Mazziotti 2002). As such,
the UFWS will scek to minimize adverse impacts to wood stork foraging habitat by requiring
compensation based on replacing any lost function provided by cach wetland type impacted
within the boundary of the project area. Wetland impacts must be compensated by offering

compensation of the same hydroperiod, or through purchase of wetland credits within a "Service
Approved" mitigation bank. The proposed project produces impacts to wood stork core foraging
habitat by construction of a pedestrian boardwalk through wetlands adjacent to the Gordon River
and construction of a pedestrian bridge over the river. Compensation for these proposed impacts
will consist primarily of extensive wetland habitat improvement, resulting from the eradication
of nuisance non-native vegetation project-area wide and its long-term management. Currently,
wetlands located throughout the project area are virtually unavailable to wood stork foraging
because of the dense cover caused by the invasion of these systems by nuisance non-natives.
Based on direction provided by the UFWS in their South Florida Programmatic Concurrence for
the Wood Stork (November 9, 2007), the extensive habitat improvement proposed should be
considered adequate mitigation for the minor impacts resulting from the proposed construction.
Similarly, the project is not likely to negatively impact the foraging habitat of state-listed wading
birds and is likely to improve foraging opportunities project-area wide.
The Big Cypress fox squirrel (Sciurus niger avicennia)
Also known as the mangrove fox squirrel, the FWC lists this species as threatened in Florida.
While the species is widespread in eastern and central North America, the subspecies is endemic
to southwestern Florida - specifically in the Immokalee Rise, Big Cypress Swamp, and Devil's
Garden area in Collier County. Some areas of this range have become vacated, while many other
suitable areas are being altered or becoming isolated through development. The subspecies uses
most types of forest occurring in its range. However, dense interiors of mixed cypress-hardwood
strands seem to be avoided by Big Cypress fox squirrels due to dense populations of gray
squirrels (Sciurus carolinensis) occupying these areas. Big Cypress fox squirrels have been
reported in cypress swamp, pine flatwood, tropical hammock, hardwood hammock, mangrove
swamp, and suburban habitats including golf courses, and residential areas in native vegetation.
Big Cypress fox squirrel densities appear to be quite low, and on this basis the subspecies can be
considered inherently rare (Humphrey & Jodice 1992).
West Indian Manatee (Trichechus manatus latirostris)
The West Indian manatee, is a State and federally listed Endangered species commonly found in
coastal, estuarine, and in riverine habitats near coastal areas. Manatees require access to
freshwater sources, vascular aquatic plants for foraging, channels of minimum 6-foot depth for
movement, and access to natural springs, coves, and warm-water refugia for foraging, mating,
and wintering. All of these conditions are found within the Gordon River and Golden Gate Canal
areas. The extensive Golden Gate Canal system, dredged in late 1960's, allows boating access to
the Gulf of Mexico for several single- and multi-family developments. This canal system flows
into Naples Bay. The West Indian manatee is drawn to and capable of accessing the inland canal
system, rivers, and bays near the project site to feed, calve, and mate. According to the Collier
County Manatee Protection Plan (May, 1995), the Golden Gate Canal/Gordon River area is not a
significant area for manatee population concentrations or mortality within the County. As such,
this region has been designated as a "Slow Speed" zone year round, including the channel (68C-
22.023(1)(c)2. Naples Bay south of Gordon River is designated as an "Idle Speed" zone all year
round including the channel (68C-22.023(1)(b)I). According to the FWC Research Institute's
2007 Manatee MOliality Report, three (3) manatce deaths occurred within a one (I) mile radius
of the preserve boundary. None of these mortalities were attlibuted to boating collisions or other

hwnan-related causes, but were natural or prenatal causes. Based on these results, the impact to
manatees and their habitat should be minimal. Impacts are largely confined to those associated
with the construction of an elevated boardwalk through a portion of the coastal mangrove forest
and a pedestrian bridge across the Gordon River. Installation of these structures and selection of
materials will use Best Management techniques to minimize impacts to the surrounding habitat.
Footers for the pedestrian bridge will be installed in the adjoining mangroves to avoid any
construction or obstruction within Gordon River that might impact manatees or their movements.
Collier County will implement the FWC's Standard Manatee Conditions for In-Water Work
(July 2005) for all bridge and boardwalk work conducted within Gordon River to ensure the
safety of manatees.
2.6 Invasive, Non-native and Problem Species
In an ecological context, an invasive species is one that is aggressive in growth and expansion of
range and tends to dominate others; its establishment and dominance can cause widespread hann
to an ecological system by altering the species composition, susceptibility to fire and hydrology
of an area. Non-indigenous species (i.e., non-native or exotic species) are those that have been
introduced purposefully or accidentally to an area outside their normal range. The characteristics
of some of these species (high rate of growth/reproduction, no natural predators, easily dispersed,
able to out-compete native species) make them invasive. Some indigenous species (a species
whose natural range included Florida at the time of European contact circa 1500 AD or a species
that has naturally expanded or changed its range to include Florida) may also become invasive.
Invasions by native and non-native species often follow an alteration to ecosystem function,
disruption of the food web, large-scale fragmentation of an ecosystem and/or disturbance (e.g.,
clearing, fire, drought, ete) of an area. While some native specics may become invasive, the
establishment and dominance of non-native species is of particular concern. The exotic plant
and animal species documented within the preserve and those that have a potential to occur
within the preserve are discussed in the following sections.
2.6.1 Invasive and Problem Plant Species
The Florida Exotic Pest Plant Council (FLEPPC) maintains a list of exotic plants that have been
documented to (I) have adverse effects on Florida's biodiversity and plant communities, (2)
cause habitat loss due to infestations and (3) impact endangered species via habitat loss and
alteration. To date, 57 non-indigenous plant species have been detected within Gordon River
Greenway Preserve, accounting for 34% of the plant species recorded there. Of these 57 exotic
species, 46 can be considered invasive (Table 8), and 38 are listed by FLEPPC (21 Category I
and 17 Category II). FLEPPC defines Catcgory I plants as those that alter native plant
communities by displacing native species. change community structures or ecological functions,
or hybridize with natives. Category II plants have increased in abundance or frequency but have
not yet altered FIOIida plant communities to the extent shown by Category I species. These
ddinitions do not rely on the economic sevelity or geographic range of the problem, but rather
on the documented ecological damage caused by these plants (FLEPPC 2007). Preserve lands
will be maintained free of both Category I and II exotic plants.

The following paragraph outlines the methods that will be used to treat exotics dependent on the
species type and location of treatment.
Most woody invasive species, with the exception of Australian pine and downy rosemyrtle, will
be killed in place with a dye-laced herbicide. Melaleuca and other exotic plants within the Mixed
Wetland Hardwoods Disturbed community may be hand cut and removed from the site or
mechanically cleared, depending upon density of the exotic vegetation and soil moisture
conditions. Downy rosemyrtle will be mowed in place and re-sprouts treated if density of plants
and soil moisture conditions allow. Where machinery cannot be used, downy rosemyrtle will be
hand cut at base, left on-site, and stumps sprayed with an appropriate herbicide. If hand cut
downy rosemyrtle density is high, the preserve manager may opt to remove plant debris. All
Australian pines growing adjacent to the Gordon River and canal, and all Australian pines
growing over 20 feet in height will be cut and removed from site. A barge will be necessary to
mobilize equipment and tree debris. A suitable staging area for the barge and tree debris will
need to be identified. All Australian pines growing under 20 feet in height and growing at least
20 feet inward from the shoreline and 20 feet away from the boardwalk/trail will be killed in
place. All herbaceous invasive exotic vegetation will be treated via foliar application. Invasive
vines may be treated via foliar application or cut-stcm application.
2.6.2 Invasive and Problem Animal Species
Although Florida does not have an official exotic, invasive animal species list, at least 400 exotic
fish and wildlife animal species have been reported in Florida, and approximately 125 species
are established.
Three non-indigenous, animal species have been documented on the preserve: squirrel monkeys
red imported fire ants (So/el1ops!s il1Victa) and brown anoles (Al1o/is sagre!). Brief descriptions
of documented and undocumented but potentially problematic species are provided in the
following paragraphs.
Squirrel Monkey (Saimiri sp.): documented within the Gordon

Squin'el monkcys are native to the tropical forest canopy layers of
Central and South America. They are omnivores, eating primarily
fruits and insects, but occasionally eating nuts, buds, eggs and small
vertebrates (Groves 2005), Groups of free- roaming squirrel monkeys

for many years. The monkeys have been observed within the Gordon River Greenway Preserve.
Red imported fire ant (Solenopsis invicta): documented within the Gordon River Greenway
Preserve
These social insects were introduced into the U.S. from Brazil
into either Mobile, Alabama or Pensacola, Florida between 1933
and 1945 (Collins & Scheffrahn 2005) and have been detected in
the Gordon River Greenway Preserve. Red imported fire ants
(RIF A) have been documented to cause harm to humans and
wildlife as well as economic harm (Stimac & Alves 1994;
Collins & Scheffrahn 2005; Willcox & Giuliano, 2006). RIFAs
are omnivorous, but they prefer insects as their primary food
source (Willcox & Giuliano 2006). RIF As have a number of
impacts on wildlife; in many areas, they have eliminated native
ant populations through competition and predation and have
eradicated food sources utilized by some wildlife species.
Ground-nesting wildlife is especially susceptible to RIF As.
Within the Gordon River Greenway Preserve, RIF As have the potential to affect ground-nesting
birds; small mammals; reptiles, native lizard and snake species, and native invertebrates (Willcox
& Giuliano 2006). Additionally, members of the public that come into contact with RIFAs may
be harmed if stung. Many people have anaphylactic reactions to the toxins released from RIF A
stings.
Brown Anole (Anolis sagrel): documented within the Gordon River Greenway Preserve
Also known as the Cuban anole, the brown anole is native to Cuba,
the Bahamas, and neighboring islands (Schwartz & Henderson
1991). Like other anoles from the islands, this species is a small,
tropical, diurnal, arboreal, territorial, and insectivorous lizard
(Campbell 2001). The brown anole was first documented in the
Florida Keys in the late 1800s (Lee 1985) and has since spread
throughout Florida, into Georgia and into
two other southeastern states (Campbell
1996). The brown anole is a habitat
generalist and generally prefers the fairly
open areas of disturbed sites. It feeds on
a wide variety of insects, amphipods, and
isopods. Brown anoles also prey on other
small vertebrates including the hatchlings of the native green anole
(A. carolinensiis; Campbell 2000).

Campbell (2000) showed that, in the absence of the exotic brown anoles, native green anoles
occupy perches from ground to the canopy of vegetation. However, in the presence of the exotic
anole, native anoles move higher in trees, occupying only the trunk and crown of trees. Dietary
overlap is high between both species, but the overall affects of the brown anole on the green
anole are still undetermined.
Cuban tree frog (Osteopilus septentrionalis): undocumented within the Gordon River
Greenway Preserve
Like the Cuban anole, the Cuban tree frog is native to Cuba, the
Bahamas, and neighboring islands, The first Cuban tree frogs
probably arrived in the Florida Keys as stowaways in shipping
crates originating from the Caribbean in the 1920's. Today, they
have established breeding populations as far north as Cedar Key on
Florida's Gulf Coast, Jacksonville on the Atlantic Coast, and
Gainesville in north-central Florida. These hylids are the largest
tree frog found in Florida and because of their ability to invade
natural areas and prey on native invertebrates and small vertebrates
(including native tree frogs) thcy are considered an invasive
species. Additionally, the tadpoles of this species inhibit the
growth and development of the tadpoles of the native southern toad
(Bufo terrestris) and green tree frog (Hvla cinerea). Cuban tree frogs thrive in residential and
natural areas such as pine forests. hardwood han1mocks. and swamps. In residential settings, they
are most commonly found on and around homes and buildings, and in gardens and landscape
plants. They are known to get into transf{mner boxes and electrical switches causing power
outages (Johnson 2007). Due to the natural communities that are found within the Gordon River
Greenway Preserve and its proximity to residential arcas, this species has the potential of
occurring in the preserve.

successful. They have since been deemed an invasive species in Florida and are currently found
in urban areas of south and central Florida, and are rapidly expanding northward (Brandt &
Mazziotti 2005). Many of this species' characteristics enable it to do well in south Florida.
Beetles, bees, ants, winged termites, crickets and bugs are a large part of the diet of the adult
marine toad. Additionally, they consume arthropods, mollusks, small vertebrates, plant matter,
pet food, carrion, household scraps, marine snails, smaller toads and native frogs, small snakes,
and even small mammals. Marine toads are prolific breeders and females can lay tens of
thousands of eggs in a single breeding season. They prefer forested areas with semi permanent
water nearby (Churchill 2003). The cane toad looks very similar to the native, southern toad, but
there are some distinct differences. The most obvious difference is adult body size (length of
body not counting the legs). Adult marine toads can reach lengths of 6 -9 inches while the native
southern toads only reach a length of 3.6 inches. Like other true toads, both possess poisonous,
parotid glands. The parotid glands of the cane toad are angled downward behind their head to
their shoulders. The southern toad has a kidney-shaped parotid gland behind each eye positioned
close to the spine. The southern toad also possesses cranial crests that start between the eyes
and often end in big knobs. While the parotid glands of all toads contain bufotoxins (poisonous,
milky fluids exuded as a defense mechanism), the chemicals released by the exotic, cane toad are
much more harmful to wildlife, pets and people (Brandt & Mazziotti 2005). Due to the natural
communities that are found within the Gordon River Greenway Preserve and its proximity to
residential areas, this species has the potential of occurring within the preserve. Adjoining
residents of the preserve should be encouraged to keep pet food and water containers indoors or
empty at night.
Feral domestic cat (Felis catus): undocumented within the Gordon River Greenway
Preserve
Domestic cats originated from an ancestral wild species, the European and African wildcat (Felis
silvestris). Humans facilitated the global distribution of cats due to their highly efficient
predatory skills. Egyptians took cats with them on shipping vessels to keep rodent populations
down, and they likely introduced domestic cats to Europe. Subsequently the expansion of the
Roman Empire and European missionary missions facilitated the spread of domestic cats into
Asia and beyond (Masterson 2007). Today, the impact of feral cats on wildlife is difficult to
quantify; however, literature (FWC 2001; Karim 2007; Masterson 2007) strongly indicates that
they are a significant factor in the mortality of small mammals, birds (including migratory birds),
reptiles, and amphibians in Florida. Because free-ranging cats often receive food from humans,
they may reach abnormally high numbers. An increase in the population of feral cats may lead
to increased predation rates on native wildlife. While no cats have yet been observed on the
Gordon River Greenway Preserve, there exists a high probability of their future presence on the
preserve due to the proximity of the Greenway to human residential areas. Adjoining residents
of the preserve should be encouraged to keep their cats indoors and staff should monitor the
preserve for the presence of feral cats.

3.2 Current Land Uses
Currently, there is no sanctioned public use of the Gordon River Greenway Preserve.
Conservation, restoration and natural resource-based recreation are the designated uses of this
preserve. Management activities allowed include those necessary to preserve, restore, secure and
maintain this environmentally sensitive land for the benefit of present and future generations.
Public use of the site must be consistent with these management goals and will be discussed in
section 4.4 of this document.
The Collier County Parks and Rec. owned Gordon River Greenway Park property abuts the
northern property line of the preserve. The preserve is surrounded on both the east and west by
planned unit developments consisting of both residential and commercial properties. The City of
Naples municipal boundary borders tlle project on the west. The Naples Airport is adjacent to
the southeastern boundary of the preserve, and an undeveloped property, zoned R-I-7.5, is
adjacent to the south boundary of the preserve. The Gordon River bisects the northern portion of
the property and forms the western boundary of the southern portion of the property. The
Golden Gate Canal forms the eastern boundary of the northern portion of the property (Figure 9).

3.3 Cultural, Historical and Archeological Resource Protection
The Gordon River Greenway Preserve is within an area of historical and archaeological
probability. A phase one cultural resource assessment completed by the Archaeological and
Historical Conservancy, Inc. (AHC) in August 2007 indicates that one archaeological site
(8CR978) is present on the property. AHC determined that Site 8CR978 is a prehistoric shell
refuse site, consisting of redeposited remains; the total loss of integrity renders the site ineligible
for listing on the National Register of Historic Places. The Florida Department of State Division
of Historical Resources does not require further investigation of Site 8CR978 prior to
development of a trail system through Gordon River Greenway Preserve; however, site plans
will avoid disturbance in this area.
The County will notify the Division of Historical Resources immediately if evidence is found to
suggest any other archaeological or historic resources are discovered. 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 Scctions 267.0612 (a) and (b).
3.4 Major Accomplishments during Previous Years
Since the acquisition of the Gordon River Greenway Preserve, Kimley-Horn and Associates, Inc.
has been hired to plan, design. and pernlit the preserve in conjunction with planning, designing,
and permitting the Parks and Rec. property adjacent to the north. A 30% design was near
completion at the time this management plan was drafted. Conservation Collier staff has also
continues to explore options of funding exotic removal and boardwalk construction through
grants from the Department of Environmcntal Protection.
4.0 Future Use of the Gordon River Greenway Preserve including
Management Issues, Goals and Objectives
This section describes the main management issues, goals, and objectives for the Gordon River
Greenway 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
Eaeh property purchased by Conservation Collier shall have its own management plan. At the
time the Gordon River Greenway Preserve as purchased. the Conservation Collier Ordinance
required that an "Interim" Management Plan be developed within 60 days of closing. Interim

Mav 20Il
Gordon River Greenwav Preserve Land Manazernent Plan
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 July 2006. The ordinance then requires a "Final" ten-year
management plan be developed within two years; the first draft of this management plan was
submitted to the Lands Evaluation and Management Subcommittee in November 2010. Because
it was anticipated that the Gordon River Greenway Preserve would be incorporated into the
Gordon River Greenway Park management plan, staff received BCC approval to extend the
deadline for submission of the final management plan until October 2010. Once approved, this
final management plan must be reviewed every five years. Final management plans, however,
are considered living documents and can be updated at any time. Review of all management
plans start in the Lands Evaluation and Management subcommittee and must be approved by
both the CCLAAC and BCe.
4.1.1 Preserve Manager: Contact Information
The site manager for Gordon River Greenway Preserve will be a designated Collier County
Environmental Specialist who may be contacted through electronic mail:
ConservationCollier@Colliergov.net.
4.2 Planned Uses and Assessment of their Impacts
Future planned use will be consistent with the primary goals of conservation, preservation,
restoration and maintenance of the resource. Official public use of the site will not be possible
until a safe public access boardwalk and trail can be created. However, citizens that desire to
visit the site prior to opening may do so by sih'J1ing a waiver that will allow them access at their
own risk and releases the liability of the County until safe access is established. Details of
planned uses for the Gordon River Greenway Preserve and an assessment of their potential
impacts are provided in the following sections.
4.2.1 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. Such uses may include, but are not limited to hiking,
nature photography, bird watching, kayaking, canoeing, swimming, hunting and fishing (Ord.
No. 02-63, as amendeds 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 76-48 (available from www.municode.com). as amended.
The following are consistent uses for this particular site: hiking, nature photography, kayaking,
canoeing, fishing and bird watching. Inconsistent uses include hunting and off road vehicle use

(ORVl in addition to development of structures other than those required for limited public
access and environmental education.
There are no existing easements, concessions, or leases at the Gordon River Greenway Preserve.
In accordance with the management goals of the preserve, no future easements, concessions, or
leases are appropriate in association with this site, other than conservation related easements.
Although not an easement, it is prudent to note that the property boundary of Nature Pointe of
Naples, Inc. extends across the Golden Gate Canal and encompasses all lands approximately 30
feet west of the western canal edge. Thcse lands, which line the Golden Gate Canal and are
directly adjacent to the Gordon River Grecnway, are currently infested with mature Australian
pine trees.
4.3 Desired Future Conditions
This section includes a description of the proposed future conditions for the site's natural areas.
Management techniques to achieve these conditions are outlined in section 4.4-
After managers complete recommended management actions, Gordon River Greenway Preserve
will consist of Mangrove Swamp, Scrubby Flatwoods. Harwood/Coniferous/Palm Mixed, and
Mixed Wetland Hardwoods; these communities will have a similar structure and composition to
those that existed before non-indigenous people settled the region and before the exclusion of
fire. With the exception of a boardwalk and trail, the site will be vegetated with appropriate
native flora that will provide suitable cover for a variety of wildlife species.
4.4 Goals for the 10 year period 2010-2020
A set of goals and objectives for Gordon River Greenway Preserve were developed in
conjunction with the drafting of this Management Plan. The goals and objectives in this plan are
tailored specifically for Gordon River Greenway Preserve based on the purposes for which the
lands were acquired, the condition of the resources present, and the management issues for the
property. On-site managers should be familiar with this entire Management Plan. Goals and
objectives from the Interim Management Plan for the Gordon River Greenway Preserve were
reviewed to detennine whether they should be included in this plan. The goals and objectives
presented here refleet programmatic goals and ideas of Conservation Collier personnel in charge
of managing and protecting the area. These goals shall not be modified, but specifie 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
objectivcs identified in this plan is dependent upon the availability of funding sources. The
following goals have been identified for Gordon River Greenway Preserve:

Action Item 1.4 Enact regular maintenance events a maximum of 3 months after initial
exotic removal
A qualified, iicensed contractor will be hired to do follow-up maintenance immediately
following initial maintenance. Growth of vines and category II exotic species may be intense
following initial removal of monocultures of category I species within the preserve. Treatment
may be necessary within one month of initial removal, but should be completed no later than
three months after initial removal. If necessary, the preserve should be swept monthly for the
first year after initial treatment. Monitoring of re-growth and new invasions should be done
monthly, and follow-up treatments should be done based upon findings during monitoring.
Action Item 1.5 A void non-target damage to native plants and animals, especially rare
species, during invasive, exotie plant treatments.
Decisions on the types of herbicides utilized will be made on the best information available at the
time of exotic removal. Staff has prohibited the use of herbicides containing Imazapyr (e.g.,
Arsenal) due to reports that these herbicides have potentially caused a great deal of non-target
damage throughout the state. Licensed County or State contractors have been (and will be)
monitored closely to ensure the proper herbicide applications are being utilized while treating the
site. In addition, close attention will be paid to identify listed epiphytes (Table 7) that may be

attached to invasive trees being cut down or removed. Plants of these species will be relocated
prior to removal. Special attention will be given to avoid damage to native species in the vicinity
of exotic removal activities. Hand pulling of exotic seedlings will be done when possible.
Action Item 1.6 Monitor non-native fauna
To date, three (3) introduced animal species have been documented on the Gordon River
Greenway Preserve, the squirrel monkey, the RIF A and the brown anole.
It is doubtful that the total cradication of the RIFA can be achieved. However, staff and/or
contractors should take measures to remove RIF A populations close to or on public access trails.
Although they do not appear to be a detriment to the preserve, public interaction with the squirrel
monkeys within the preserve should be discouraged. If the squirrel monkey population within
the preserve appears to be increasing, monitoring of the population should be implemented.
If feral cat colonies are found near the preserve, the clements that sustain the undesirable
population(s) should be identified and efforts made to ask property owners to eliminate them
(i.e., refuse bins, dumpsters, and supplementary feeding by humans). If any feral cats remain,
they will be trapped and taken to Collier County Domestic Animal Services.
GOAL 2: DEVELOP A BASELINE MONITORING REPORT
Action Item 2.1 Establish a long-term biological monitoring program and conduct
additional wildlife surveys.
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. This section discusses infonnation needs and long-term monitoring
needs.
ENTRIX staff conducted a floristic inventory of the Gordon River Greenway Preserve in 2009;
these findings comprise the baseline floristic data on which future actions will be based. The site
should be inspected by Conservation Collier Staff at least twice a year and thoroughly
inventoried at regular intervals (ca. 5-10 years) to detect new invasions (by natives or exotics)
and extinctions. Areas undergoing extreme restoration should be assessed more frequently.
While some wildlife data has been collected, additional baseline data should 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 sampling, like plant sampling, on non-listed species only, should take place at
regular intervals (ca. 5-10 years) to detect long-term trends.
Prior to rcstoration, photo point stations will be cstablished within the different plant
communities throughout the preserve. Locations of photo points will be recorded with a GPS
and all photographs will be taken at a standard height and angle of view. During photo
documentations. one photo will be taken in each of the cardinal directions (north, east, south and
west). These photos will help to monitor exotic rcmoval and native plant recruitment over time.
If necessary, more photo points will be established to aid in management decision activities.

Action Item 3.1 Identify locations of rare and listed native plant species.
The location of these 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.
Action Item 3.2 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 Sheriffs Department.
Action Item 3.3 Maintain a revised GIS map and description of FNAI natural communities
and disturbed areas on the property.
Maintaining updated maps will help to guide restoration efforts
Action Item 3.4 Plant native plant species in their appropriate habitats
Periods following exotic removal and prescribed fire (or mechanical treatment) are essential to
the recruitment of native plants. If native plant recruitment is not sufficient from the
surrounding, intact seed source, efforts will be made to plant indigenous flora in appropriate
habitats. Natural area restoration of Gordon River Greenway Preserve should include only site-
specific native plant material that has been determined to be non-problematic at the site and
whenever possible, site-specific seed sources should be utilized.
Action Item 3.5 Install signs cncouraging people to stay on any future public access trails
situated on the preserve.
Action Item 3.6 Note and research all site development occurring adjacent to Gordon River
Greenway Preserve to determine that the proper site development permits have been
obtained and that the site development complies with the permits.
Activities on adjacent lands may have an impact on the indigenous plant and animal life on the
Gordon River Greenway Preserve. As such, all existing local, state, and federal regulations
should be strictly followed and enforced during any site development adjacent to the preserve. It
shall be the responsibility of the developer to establish erosion control measures and vegetation
protection measures (i.e., protective fencing or barriers). If any site developer working in areas
adjacent to the preserve does not take the necessary control measures. construction shall be
immediately halted until control measures are put into place and mitigation and/or remediation
will be the sole responsibility of the developer.
GOAL 4: DEVELOPAND IMPLEMENT A PLAN FOR PUBLIC USE
Action Item 4.1 Continue to coordinate design and permitting plans with Parks and Rec.
through Kimley-Horn and Associates, Ine. (Kimley-Horn)
Kimley-Hom was selected to plan, permit and design (PPO) the Gordon River Greenway Park
by Parks and Rec. via the Collier County Request for Proposal process. Prior to executing a
contract with Kimley-Hom, Conservation Collier coordinated with Parks and Rec. to include the
Gordon River Greenway Preserve in the Gordon River Greenway Park PPO process. This
allows Collier County to PPO one single project instead of two separate projects. Kimley-Hom
is responsible for designing and permitting the boardwalks, trails, shade structures/rest pavilions,

observation overlook, fishing platform, educational signage and pedestrian bridge within the
Gordon River Greenway Preserve.
Action Item 4.2 Maintain visitor amenities a minimum of 100 feet from known yellow-
crowned night heron rookery island
The yellow-crowned night heron is a colonial nester in swamps and marshes. A yellow-crowned
night heron rookery exists on a small mangrove island at the southern extent of the project,
located at the intersection of Gordon River and the Golden Gate Canal. Efforts will be made to
locate the bridge as far away from this rookery as possible. Signs placed around the island to
keep kayakers/ canoers and boaters away from the island may be installed if necessary.
Action Item 4.3 Identify actual and potential locations of other resident animal life and
take steps such as locating visitor amenities away from animal nesting sites.
Action Item 4.4 Develop access and required facilities for intended puhlic uses
Kimley-Horn site plans for the project, dated January 25,2011, are currently at 30% design. See
Figure 10. To be consistent with the overall project. preserve boardwalk widths will be 10 feet;
trail widths will be 12 feet. Trail system will follow the approximate ali!,'TIII1ent as shown in
Figure ] I; however, installation of all boardwalks and trails will be field located to ensure the
least impact to native vegctation. ADA trails are anticipated to occur within the upland portions
of the preserve. If funding allows. a raised boardwalk trail will replace the at grade ADA trail
through the scrubby f1atwoods section of the preserve.

GOAL 5: FACILITATE USES OF THE SITE FOR EDUCATIONAL PURPOSES
Actions Item 5.1 Provide preserve brochures in rainproof box on site.
A brochure outlining the native plant communities and wildlife present at the preserve will be
created by County staff and kept in rainproof boxes near the preserve entrance. The preserve
manager will inspect these boxes monthly and refill as necessary.
Action Item 5.2 Facilitate Parks and Rec. educational programs
Once the boardwalk, trails and bridge are complete, Parks and Rec. staff will begin educational
programs along the Gordon River Greenway extending into the preserve. Conservation Collier
program staff will cooperate with Parks and Rec. and assist whenever possible. Appropriate
signage will be utilized for public education regarding resource conservaton.
GOAL 6: DETERMINE IF PRESCRIBED FIRE AND/OR MECHANICAL TREATMENTS ARE
FEASIBLE TO DECREASE WOODY INVASION RESULTING FROM PAST FIRE
EXCLUSION; IF SO, PROCEED
Action Item 6.1 Coordinate with Parks and Rec. to see if the adjacent Gordon River
Greenway Park should be included within the burn management zones of the Gordon
River Greenway Preserve.
Action Item 6.2 Develop a prescribed fire or mechanical treatment plan to mimic natural
fires within the scrubby tlatwoods plant community.
Unless absolutely necessary, fire breaks should not be created along ecotones. Firebreaks along
ecotones prevent fires from burning across the I andscape between different habitat types, and the
trails themselves destroy habitat for species that require specific ecotonal habitats.
The scrubby flatwoods community within the preserve should be burned at an interval of 8-25
years. Summer headfires will probably be needed to ensure that most vegetation ignites and that
the fire moves across the habitat For best results, prescribed fire management should begin after
permanent firebreaks have been established. Prior to any prescribed fires, bum teams should
assess fuel loads and conduct fuel reduction where necessary, conduct risk assessment for the
planned bum, obtain appropriate permits, and coordinate with local fire officials. Exotic plant
species in particular should be removed prior to fires. Additionally, a plan of action for the
Preserve Manager to notify surrounding residents should be established.
If the application of prescribed fire is absolutely impossible there are several alternatives that are
available, although mueh less desirable. These options include herbieide application, mechanical
treatment, and grazing. Both herbicide application and meehanical treatments have the
disadvantage of requiring that dead woody material be removed from the site following
treatment, limiting the amount of decomposing vegetation that would create organic soils. Even
with physieal removal after treatment, organie matter from all plants on the sites will eventually
accumulate, leaving an organic soil, and thereby reducing diversity of native herbs. Grazing,
such as by goats, has the disadvantage in introducing trampling effects, nutrients from feces, and
possible spread of exotic pest plant seeds. Staff will coordinate with the Florida Division of
Conservation Collier Prograrn

Gordon River Grcenwav Preserve Land ..Manaf!ement Plan
Forestry's Urban Fire Mitigation Team to create a bum plan for the site, conduct pre-fire fuel
reduction and firebreak creation, and to conduct prescribed bums.
Action Item 6.3 If fire is deemed appropriate, delineate fire management and rescue access
routes, and provide this information to the police department and emergency services.
GOAL 7: PROVIDE A PLAN FOR SECURITY AND DISASTER PREPAREDNESS
Action Item 7.1 Discourage any visitation to the park after hours.
Electronic, timed gates will be installed at all entrances of the County's Greenway project.
These gates will open and close automatically when the preserve is open and closed respectively.
While the preserve is closed, visitors will be able to open the gates to leave the preserve, but not
to enter. A sign designating the Greenway hours of operation will be installed at the 2 entrances
to the preserve.
Action Item 7.2 Determine whether security lighting is appropriate along the trail system
within the preserve.
Security within the preserve is inherently connected to security throughout the entire Greenway
system. If lighting for security purposes is detennined to be necessary, lighting within the
preserve should be the minimum required and should be focused down toward the trail, so as to
minimize light pollution.
Action Item 7.2 Enforce regulations prohibiting trash and landscape debris dumping in or
near the preserve.
Currently, there is no vehicular access and dumping is not a problem. Monthly inspections will
determine if dumping becomes a problem. Staff will work with the Collier County Sheriffs
Office to address dumping if it becomes a problem.
Action Item 7.3 Survey trees along the trail and the perimeter of the property annually for
damage
StatT will utilize the services of a certified arborist to detemline diseased, weak, or damaged
trees/limbs surrounding the trails and kiosks that should be removed for safety reasons and prior
to hurricane season. This activity is intended to reduce the risk of visitor injury.
Action Item 7.4 Visit preserve within 48 hours after a storm event to assess damage.
Staff will take photos of damage and Ell out appropriate Collier County Risk Management
Depm1ment fomls. If damage is extensive, the preserve will be closed until public safety hazards
are cl eared.
Action Item 7.5 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
hurricane debris as possible will be chipped and retained on-site - to be used as mulch for the
trail.

4.5 Establish an Operational Plan for the Gordon River Greenway Preserve
This section provides management recommendations for operation of the Gordon River
Greenway Preserve. It discusses maintenance and budgeting needs, coordination, and other
management issues.
4.5.1 Maintenance
The primary maintenance activities for the preserve will include control of dumping and littering
within and around the preserve and trail. Particularly important are the security measures to keep
vandals out and the signage and gates in good conditions. The boardwalk and pedestrian bridge
should be inspected annually for structural integrity.
4.5.2 Estimated Annual Costs and Funding Sources
Preliminary budget estimates for Gordon River Greenway Preserve include cost breakdowns
associated with resource restoration and management and public access site development. The
funding source identified for these activities is the Conservation Collier Program Management
Trust Fund. Grants will be sought to supplement existing management funds and specifically for
the costs associated with the construction of the boardwalk and pedestrian bridge.
The budget in Table 10 represents the actual and unmet budgetary needs for managing the lands
and resources of the preserve for the next ten years. The table shows the activities planned 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, equipment purchase and maintenance, and for development of fixed
capital facilities. The budget considers available funding and is consistent with the direction
necessary to achieve the goals and objectives for Gordon River Greenway Preserve.
