EXECUTIVE SUMMARY
Recommendation to approve an Interim Management Plan for the Mcllvane Marsh
Project 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
attached Interim Management Plan (IMP) for the Mcllvane Marsh Project under the
Conservation Collier Program and 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 no later than ninety (90) days from the date of acquisition, an IMP 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. Subsequent to the
Interim Management Plan, a Final Management Plan is to be presented to the Board within two
(2) years.
-
Parcels within the Mcllvane Marsh Project began to be acquired in July 2007, with the final
parcel acquired in August 2009. The Mcllvane Marsh Project is located south of Tamiami Tr. E
and East of 951 ~ of Curcie and San Marco Road. The Project consists of eight parceis
totaling 368 acres located within Sections 29 & 30, Township 51 South and Range 27 East.
Collier County.
The Interim Management Plan was reviewed by the Lands Evaluation and Management
Subcommittee at a publicly-noticed meeting on November 13, 2009. After reviewing the
proposed plan, taking public comment and suggesting revisions, the Lands Evaluation and
Management Subcommittee made a unanimous recommendation to forward the attached
revised draft IMP to the CCLAAC. On December 14, 2009, at its regular, publicly noticed
meeting, the CCLAAC had discussion, requested additional changes, and subsequently voted 7
to 0 to forward the revised IMP to the Board with a recommendation of approval.
FISCAL IMPACT: Initial land management activity costs are estimated at $104,000, of which
$90,000 is for exotic control. However, staff recently learned that U.S. Fish and Wildlife has
awarded Conservation Collier a $21,000 matching grant for exotic control, so actual initial costs
will be less. Management activities for each subsequent year are estimated at $23,000, again,
primarily for exotic control. Staff is working to coordinate exotic control with surrounding public
land owners, thereby reducing this amount in subsequent years through economies of scale.
Funds are budgeted within the Conservation Collier Land Management Fund to accomplish
necessary management 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.

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. T:-h~ recommeiidation of the McUvane Marsh Project Interim
Management Plan by the Conservation Coiiier Land Acquisition Advisory Committee for Board
approval falls within this legal framework. The Interim Management Plan is legally sufficient for
Board action. -JBW
RECOMMENDATION: That the Board of County Commissioners approves the attached Interim
Management Plan and directs the County Manager, or his designee, to implement it for the
Mcllvane Marsh Project.

Interim Management Plan
1.0 Purpose and Scope of the Interim Management Plan
The McIlvane Marsh project consists of 8 properties totaling 368 acres acquired between July
2007 and August 2009 with funds from the Conservation Collier Program (Exhibit I). Collier
County additionally owns, under the Transportation Department, a 20-acre parcel within the
marsh donated as mitigation in 1999. The State of Florida, under management by Rookery Bay
National Estuarine Research Reserve (RBNERR), owns or is in the process of acquiring
additional 329 acres (in a mosaic pattern with Conservation Collier's acquired lands) for a total
of 717 acres currently or shortly to be in conservation status out of a total of approximately 807
acres within the marsh. There are seven remaining privately-owned parcels totaling 90 acres; 80
acres located on the western side and 10 acres on the east side of the marsh. Conservation
Collier parcels will be managed for conservation, protection, enhancement of natural resources
and for public outdoor recreation that will he compatible with the conservation, protection and
enhancement of the site and the surrounding lands.
This Interim Management Plan is intended to identify the key management priorities and issues
within the site and give direction for management for two years. This document is meant to be
the precursor to a Final Management Plan, which will outline more specific aspects of site
management.
Kev Interim Management Obiectives
I. Protect, manage and restore (as appropriate) the native habitat on site
Action Plan
] a. Install a temporary Conservation Land sign at the Curcie Road access point to McIlvane
Marsh area and evaluate the nced for No Dumping I No Trespassing signs along internal
rights of way.
1 b. Seek grant funding for invasive exotic vegetation removal ($21,000 matching grant
awarded from U.S. Fish and Wildlife Service Partners Program for federal fiscal year 2009
for removal of exotics).
1 c. Meet and coordinate with surrounding conservation land managers and agencies for
coordination of invasive exotic vegetation treatment and development of wildlife survey
protocols.
2. Develop Partnership agreement(s) for management with surrounding land owning
agencies and private individuals
Action Plan
2a. Coordinate with property owner agencies surrounding the Marsh, including Collier
Seminole State Park, Ten Thousand Islands National Wildlife Refuge (TTINWR) and
RBNERR for long term management and public access cooperation.
2b. Write and execute a formal Memorandum of Agreement (MOA), also known by the
U.S. fish and Wildlife Service (USfWS) as a "Management Agreement," for cooperative
land management actions with appropriate adjoining agencies.
2c. Coordinate management of the ?O-acre mitigation parcel acquired by Collier County in
1999 with Conservation Collier management.

Interim Management Plan
3. Plan for appropriate public access.
Action Plan
3a. Coordinate appropriate publi~ use plan with RBNERR and TTINWR.
3b Evaluate appropriate areas for public parking.
3c. Evaluate potential and costs for fishing/canoe launch/wildlife viewing dock.
3d. Evaluate information regarding a verbal report from RBNERR statT about a possible
area of lead contamination due to past discharge of firearms on state property that abuts
Conservation Collier lands. If substantiated and warranted, a Phase II Environmental Site
Assessment can be done to determine the level of contamination, whether this presents a
hazard for people or wildlife, and what the appropriate abatement steps are.
4. Continue to explore opportunities for post acquisition grant funding.
5. Determine impact on resources necessary to manage the area for the dynamics and
impacts associated with public access.
2.0 Management Authority and Responsibilities
The McIlvane Marsh properties have not been officially named at present. McIlvane Marsh is
the unofficial historic area name. Eight parcels totaling 369 acres are included within the
portfolio of properties assigned to the Collier County Facilities Management Department, with
the Conservation Collier Program responsible for direct management of these lands.
Conservation Collier Program staff will handle day to day management activities and will seek to
cooperate and form partnerships with adjoining land-owner local, state and federal agencies and
to obtain various types of grants for management and public use activities where possible.
3.0 Interim Site Plan
3.1 Location and Site Description
The McIlvane Marsh is an 800-acre mangrove salt marsh generally located northeast of Marco
Island and southwest of the intersection of U.S. 41 (Tamiami Trail) and County Road 92 (San
Marco Road) in Sections 29 and 30, Township 51 South, Range 27 East, Collier County, Florida.
The McIlvane Marsh area can be accessed via Curcie Road, which turns north off C.R. 92
approximately 1.8 miles south of U.S. 41. The first 800 feet of Curcie Road is County-
maintained right-of-way (ROW). Curcie road continues beyond the County-maintained ROW
as an unpaved private access road to the north edge of the McIlvane Marsh, curves west and
continues for approximately 2.1 miles to a terminus point in the northwestern portion of the
marsh. This unpaved road can be used to legally and physically access Conservation Collier
lands, though it traverses over lands owned by The State of Florida Department of
Enviromnental Protection, managed by RBNERR. There are several other non-contiguous
portions of public ROW dedicated along the edges of Conservation Collier properties within the
marsh; however there are no actual roadways in these locations.
McIlvane Marsh is situated near and is expected to be influenced by the Picayune Strand
Restoration Project, a sub-project of the Comprehensive Everglades Restoration Project. The
project area includes 55,000 acres located between Alligator Alley and Tamiami Trail in
southeastern Collier County and involves plugging canals, building and operating pump stations,
placing culverts under the Tamiami Trail, removing old road beds and removing exotic

vegetation. The goal of the project is to improve estuarine water quality by increasing
groundwater recharge and reducing large and unnatural freshwater inflows to the estuaries along
the southwest Florida coast. While this project does not directly affect the County's parcels
within the McIlvane Marsh area, it is expected to increase surface water in the general area.
There is additionally planned, but with portions as yet unfunded, a Picayune Strand Restoration
"protection feature" project involving enhancing existing culverts under the Tamiami Trail close
to C.R. 92 and further spreading sheet flow into the McIlvane Marsh area. Already completed in
2005 is the enhancement of culverts under Tamiami Trail between S,R. 29 and C.R. 92.
Remaining proposed tasks include enhancing the canal along the east side of the McIlvane Marsh
and diverting some of that canal flow west into the marsh on state lands adjoining Conservation
Collier parcels (Conceptual Project Map - Exhibit 2). There are no actions required on the
County's part to accommodate this project; however, if and when completed, it is expected to
provide an overall environmental benefit to the entire McIlvane Marsh.
December 2009
McIlvane Marsh is a tidally influenced wetland consisting primarily of open marsh and
mangrove wetlands with small upland island areas, primarily on its northern and eastern edges
(Exhibit 3). Approximately 15-acres of pine tlatwood uplands exist on the north side of the
marsh and 6 acres of cleared uplands on the eastern edge of the marsh where a communication
tower site is located. This communication tower sits on a ten-acre parcel surrounded by
Conservation Collier lands on the eastern side of McIlvane Marsh and is owned by a private
entity. Also on the eastern side of the marsh, in what were historically uplands, state mitigation
lands contain a 51-acre borrow-pit lake created as a result of limestone fill mining which
occurred under Collier County Excavation Permit number 59.145 (Marco Woods) issued in July
1982, South Florida Water Management District Water Use Permit NO.1] 0589335, issued in
November 1982, and US Army Corps of Engineers dredge and fill permit No. 82J-10657, issued
in April 1983. Another, older approximately l-acre borrow pit created between 1963 and 1973
lies on the north-central side of the marsh on Conservation Collier lands. Vegetation
communities present within the marsh include, in order of dominance: mangrove swamp,
saltwater marsh, inland ponds or sloughs, and pine tlatwood.
3.2 Signage
An access gate exists at the end of the paved portion of Curcie
road, approximately 800 teet off C.R. 92. A temporary sign
identifying Collier County Conservation Land will be posted at
the gate. Temporary No Trespassing / No Dumping signs may
also be posted along the unpaved portion of Curcie Road. All
landowners, including Conservation Collier, will be able to put
signs onto the main gate.
Curcie Road gate
3.3 Easements. Concessions or Leases
As noted previously, there is legal and physical access to Conservation Collier properties via
public ROW along Curcie Road and via ROW dedications. Additionally, there are several non-
contiguous portions of public ROW dedicated along the edges of properties within the marsh
which have no physical roadway existing. No other easements, concessions or leases exist on

the parcel or are proposed for the future, unless they further conservation objectives, such as a
conservation easement.
3.4 Structures
The 800-acre marsh area is undeveloped and covered with natural vegetation except for three
communication towers and a small building that houses communication equipment on a ten-acre
privately owned property. Additionally, there is a 2.02-acre homestead with a recreational motor
vehicle located north of the 80-acre former Trinh parcel, with one individual intermittently
residing there.
State and Army Corps permits issued in the 1980's authorized the construction of a berm
separating the mining project from State surface waters on the south side of the limestone fill
mine excavation. The State of Florida, as part of mitigation for development projects in the local
area, has recently completed berm breaches and installation of geoweb crossings and culverts
under the access road to allow for overland flow of water in the marsh. This project was
conducted on state lands; however the benefits are expected to extend to County-owned lands.
3.5 Surrounding and Adjacent Land Uses
The Marsh is surrounded on the east, south and west by state and federal conservation lands;
Collier Seminole State Park to the east, TTINWR to the south and RBNERR to the west.
Parcels adjoining the northern boundary of the marsh include undeveloped Agriculturally-zoned
lands, Fiddler's Creek Planned Unit Development (PUD) and JDs Auto Ranch, an automotive
recycling and dismantling yard (Exhibit 3). In addition to the lands acquired for the
.. Conservation Collier Program, Collier County owns a 20-acre mitigation parcel on the western
side of the marsh that is between Conservation Collier lands on both its east and west
boundaries. The State of FloridalRBNERR owns, or will shortly own, 399 acres in a mosaic
pattern with Conservation Collier lands.
4.0 Interim Management Objectives
4.1 Natural Resource Protection
Existing Vegetation:
. Ground Cover: Mangrove areas do not appear to have ground cover. Scattered upland areas
may contain ground cover similar to that observed on parcels located off Curcie Road along
eastern side of the marsh area. Plants observed include: beakrush (Rhynchospora sp.), leather
fern (Arostichum spp.), swamp fern (Bleehnum serrulatum), and white beggar-ticks (Bidens
alba).
. Midstory: Red mangroves (Rhizophora mangle), black mangroves (Avicennia germinans),
white mangrove (Laguncularia raeemosa), buttonwood (Conocmpus ereetus), winged sumac
(Rhus copallina), myrsine (Myrsine floridana), saltbush (Baceharis angustifolia and B.
halimifolia), wax myrtle (Myrica eerifera) and scattered small cabbage palms (Sabal
palmetto).

4.2 Site Security
Security shall be provided initially by limiting access via the heavy-duty gate installed by the
State 50 feet past the bridge at the end of the paved portion of Curcie Road. Conservation
Collier staff, RBNERR and TTINWR staffs and seven owners of private properties within the
marsh have the access code. Once public use is determined, appropriate access can be provided.

4.3 Exotic Vegetation Removal and Maintenance Plan
Invasive, exotic plants present include, in order of dominance: Brazilian pepper (Schinus
terebinthifolius), Australian pine (Casuarina sp.), Melaleuca (Melaleuca quinquinerva),
climbing fern (Lygodium microphyllum), Java plum (Sygyium cumini) and other Florida Exotic
Pest Plan Council (FLEPPC) category I and 2 exotic plants. The U.S. Fish and Wildlife Service
(USFWS) is currently coordinating a mitigation project stemming from an environmental
violation that involves exotic removal adjacent to the 29.33-acre Conservation Collier parcel
(fi'k1a Triangle Leasing Corp.) adjoining Curcie Road. Staff has applied for and received notice
of a USFWS Partners grant match award of $21,500 to remove exotic vegetation on an 80-acre
parcel along the north side of the marsh (f/kla the Trinh parcel). Some exotic removal has
already occurred within the marsh on state-owned parcels. The State of Florida (via RBNERR)
is currently in the middle of a 5-year mitigation project (for the Artesa Pointe project) involving
accepting 70 acres of wetlands and uplands within McIlvane Marsh and monitoring exotic
removals from them. Staff will seek to coordinate overall exotic vegetation removal and
maintenance on adjoining Conservation Collier lands with RBNERR to achieve potential
economies of scale.
4.4 Debris Removal
This area has been historically prone to trespass and illegal dumping. Much of the debris from
past dumping has already been removed as part of restoration work done by the State of Florida
and by individual property owners. The heavy duty gate installed on Curcie Road will protect
Conservation Collier lands from dumping until an appropriate public access plan can be
prepared. "No Dumping" signs and a fence may need to be installed. Staff will evaluate this
need after determining whether the gate is effective at deterring trespass and dumping.
4.5 Cultural, Historical and Archeological Resource Protection
A Section, Township, and Range query of the Florida Master Site File for Sections 29 & 30,
T5lS, R27E, with result received on July 22, 2009, shows no recorded historical or
archaeological sites present within the search area. However, the search area may contain
unrecorded archeological sites, historical structures or other resources. The County will notify
the Division of Historical Resources immediately if evidence is found to suggest any
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 Sections 267.0612 (a) and (b).
4.6 Listed Species Protection
Many of the listed species present in McIlvane Marsh are birds. Recently, a group of trespassers
shot and killed a number of birds in the marsh, some of them listed species. Any bird rookeries
present on or adjacent to Conservation Collier will be protected by signage stating "Protection

Area-No-Entry." Florida panthers use the northern portions of the marsh, as evidenced by
FWCC telemetry data (2008 GIS telemetry layer) (Exhibits 3 and 4), and Florida black bears
have been sighted in the area. American crocodiles nest within 1.5 miles of McIlvane Marsh, at
the Marco Airport. Staff will coordinate with surrounding state and federal agencies to
determine appropriate protection actions and propose these within a Final Management Plan.
December 2009
4.7 Public Access
At present, there are no public access facilities within McIlvane Marsh. Staff has the gate
combination and can provide limited access to County-owned parcels within the marsh area by
appointment until comprehensive public access plans can he developed in concert with RBNERR
and TTINWR. Staff will evaluate the site to determine potential public uses as part of the
development of a final management plan. Estimated costs for a 5-space public parking lot are
included within the Estimates Cost Table (Exhibit 5) for future planning purposes only.
4.8 Site Monitoring and Long Term Management Plan
Long tenn management of the site shall consist of invasive exotic vegetation re-treatment and
periodic general observation wildlife survcys. Collier County shall be responsible for property
maintenance with tasks contracted ulli as necessary am) management partnerships sought with
the surrounding public land management agencies. The site will be monitored for exotic
vegetation re-growth semi-annually for two years following initial treatment. After two years, an
appropriate exotic vegetation management plan will be developed, with the goal of having 5% or
less exotic vegetation on site. Wildlife surveys shall be developed and coordinated with
surrounding conservation agencies to determine monitoring plan goals, techniques and
parameters. The overall goal of wildlife monitoring shall be for developing, evaluating, and
guiding future management actions necessary to enhancc and protect wildlife habitat.
4.9 Partnerships
Staff will seek out and evaluate potential for partnerships for conservation, protection, and
education.
4. I 0 Fire Management
RBNERR reports that there are fire dependent commumtIes on their parcels adjoining
Conservation Collier lands and that they may, in the future, apply prescribed fire to these areas.
Staff will evaluate the potential for prescribed burning on County-owned lands and seek to .
coordinate with RBNERR on all fire management issues.
