Agenda 06/27/2023 Item #16A16 (Preserve Winchester Head Interim Management plan update under the Conservation Collier Program)06/27/2023 EXECUTIVE SUMMARY Recommendation to approve the Conservation Collier Winchester Head Preserve Interim Management Plan update under the Conservation Collier Program. OBJECTIVE: To obtain approval from the Board of County Commissioners (Board) for the Winchester Head Preserve Updated Interim Management Plan. CONSIDERATIONS: Conservation Collier Ordinance, No. 2002-63, as amended, Section 14(1), requires an Interim Management Plan to be prepared for review by the Board. An Interim Management Plan was developed and approved by the Board on October 28, 2008, Agenda Item 16.E.2. The approved plan, with periodic changes, has been operational for the Winchester Head Preserve since that time. Tracked changes have been made so that Board members can quickly see the proposed changes. A "clean" version has also been provided. Current changes to this plan include: - Updated maps, - Property status information, - Additions to plant and animal lists, - Status of exotic plant and animal infestations, and - Streamlining of text. At the March 8, 2023, the Conservation Collier Land Acquisition Advisory Committee (CCLAAC) reviewed Item 5Ai, the Winchester Head Preserve Interim Management Plan update, and recommended submittal to the Board for approval. Since 2005 Conservation Collier Program has acquired 95.8 acres of the 157.5-acre Winchester Head project boundary. Parcels continue to be acquired within the project area. This primarily wetland area with depressional soils is in the north Golden Gate Estates north of Oil Well Road and east of Everglades Boulevard. Staff will prepare a Final Management Plan when at least 75% of the project area is under County ownership. The lack of contiguous parcels creates inefficient management conditions. Staff are currently only managing parcels with heavy infestations, and those that were donated to the program with management funds where invasive exotic plants were treated before acceptance. FISCAL IMPACT: Annual costs are estimated at $20,000 per year for the next five (5) years. This is primarily for invasive plant maintenance. Funds are available within the Conservation Collier Land Management Fund (174) to accomplish these activities. GROWTH MANAGEMENT IMPACT: No specific growth management impact is associated with this item. LEGAL CONSIDERATIONS: The Conservation Collier Ordinance No. 2002-63, as amended, in Section 14, provides a legal framework for the development of management plans and for the use of environmentally sensitive lands. This item is approved for form and legality and requires a majority vote for Board approval. -SAA RECOMMENDATION: To approve the proposed Interim Management Plan update for Winchester Head Preserve and direct staff to implement the updated plan.

The Winchester Head Project boundary encompasses 114 parcels totaling 157.53 acres. As of January 2023, 70 parcels or 95.8 acres (61 %) have been acquired by Conservation Collier in a checkerboard fashion throughout the project area. The Collier Soil and Water Conservation District (CSWCD) owns two parcels totaling 2.28 acres within the project area. Conservation Collier conducted a market study appraisal in 2022. As of 2022, the Property Appraiser is valuing parcels within this area between $25,000 and $55,000 per acre depending on the size and percent cover of wetlands. That market study included two appraisers with an average value for these parcels at $30,000 per acre. Conservation Collier is currently continuing to pursue the acquisition of all approved parcels within Winchester Head as means to do so present themselves. Conservation Collier has begun to make offers to owners submitting applications within Winchester Head utilizing funds from offsite preservation received as part of the Land Development Code's Off -Site Native Vegetation Retention Requirements (LDC Section 3.05.07H.l.f.iii.a). Additionally, offsite preservation parcels may be donated within this area (LDC Section 3.05.07H.l.f.iii.b). Five parcels have been acquired as offsite mitigation donations since 2013 within the project area, and one additional parcel (1.14 acres) was donated to offset Code Enforcement Liens, for a total of 7.29 acres donated If additional properties cannot be acquired using the above means, or it becomes apparent that few properties can be acquired in this manner, Conservation Collier staff will seek to exercise a provision of the Conservation Collier ordinance (2007-65, Section 14.7 as amended) that allows for the exchange of lands within and between multi -parcel projects in accordance with the goals of the Program. The objective of any such exchanges will be to consolidate the areas owned by Collier County under the Conservation Collier program into one contiguous area. All acquired properties will be managed only for conservation, protection, and enhancement of natural resources and for public outdoor recreation that will be compatible with the conservation, protection, and enhancement of the site and its surrounding lands. Public use of the site will not be practical until more contiguous properties within Winchester Head can be acquired and a trail or boardwalk constructed, the boardwalk of which is not presently funded. This interim management plan is intended to update the key management priorities and issues within the site and give direction for management through 2025. This document is intended to be the precursor to a final management plan, which will provide more specific aspects of site management once a contiguous block of properties can be assembled. 3 Packet Pg. 681 16.A.16.a February2023 Conservation Collier: Winchester Head Project Extended IMP Key Interim Management Objectives 1. Monitor vegetation until a contiguous block in the center of the project can be acquired which will trigger more extensive vegetation management actions. 2. Treat offsite donation parcels for invasive exotic plants on an annual basis. 3. Explore opportunities for grant funding and partnerships for management. Action Plan 1 a. Make bi-annual site visits to monitor the spread of Category I and II invasive plant species within parcels. Once a contiguous tract of the project is acquired, begin exotic plant management within this tract; Continue monitoring the remainder of parcels. lb. Treat all Category I and II invasive plant species within offsite mitigation donation parcels on an annual basis. 2a. Seek grant funding opportunities for the removal of exotic flora. 2.0 Management Authority and Responsibilities The Conservation Collier Program, part of the Collier County Parks & Recreation Division since October 2012, will be solely responsible for managing the Winchester Head parcels, but will also seek to obtain grants and form partnerships for management activities. 3.0 Interim Site Plan 3.1 Location and Site Description The Winchester Head Parcels are located east of Everglades Blvd. North, between 4 1 " Ave NE and 351h Ave NE in Sections 8 & 17, Township 48 and Range 28 in Golden Gate Estates, Units 62 and 65 within Collier County, Florida. The southernmost parcels are located south of 371h Ave NE but do not extend to 35th Ave NE (Exhibits 1-5). The approximate center of the project is located at 26°18'9.67"N and 81°32'19.58"W. Winchester Head is comprised of Mixed Wetland Hardwoods (FLUCCS 617), Cypress (FLUCCS 621), Cypress, Pine, Cabbage Palm (FLUCCS 624) and Freshwater Marsh (FLUCCS 641). Compared to the higher elevations of the lands surrounding Winchester Head, from 18 to 24 feet above sea level, the natural depression of this cypress area (Exhibit 6) at 15-17 feet below sea level, combined with the presence of hydric, poorly drained soils allows for water to collect and slowly percolate into the ground. Thus, Winchester Head is ideal for obligate and facultative wetland plant and animal species. Conservation Collier's Winchester Head multi -parcel project is within the North Golden Gate Estates (NGGE) Flowway Restoration Project (Exhibit 7), which is an area of focus within the County's Watershed Management Plan (WMP). The goal of this project is to reconnect the historic flowway and redirect storm water drainage away from NGGE's canals, allowing it to move south toward North Belle Meade and naturally low county areas while allowing ground absorption along the way. As part of the WMP, a Phase I and Phase II analysis of the flowway, which includes Winchester Head, have been completed. The Phase I estimated that Winchester Head contains approximately 414.7 acre-feet of storage based on an average, water surface elevation of 16.0 feet (North American Vertical Datum of 1988). The goal of reconnecting wetland systems within the NGGE has been Packet Pg. 682 16.A.16.a February2023 Conservation Collier: Winchester Head Project Extended IMP incorporated into development of the County's Watershed Management Plan, approved by the Board of County Commissioners in December 2011. The WMP includes structural projects and policy initiatives, both of which would affect the Winchester Head area. Structural projects include adding culverts and other water management structures. Policy initiatives include a potential Transfer of Development Rights (TDR) process and a Watershed Mitigation Program. The TDR process provides an equitable method of protecting and conserving the most valuable environmental lands, including large, connected wetland systems and significant areas of habitat for listed species of fish, plants, and wildlife, while allowing owners of such lands to recoup lost value and development potential through an economically viable process of transferring the development rights in such lands to other, more suitable lands. At present, no specific projects have been authorized. If Conservation Collier were to acquire and restore parcels within Winchester Head, this would serve WMP goals. However, the choice of projects determined for Winchester Head and north of Winchester Head within the flowway could affect how Conservation Collier approaches management. Structural projects could increase the volume of water stored within the WH project boundaries and thus alter proposed management actions, while a proposed TDR program could assist Conservation Collier in acquiring more parcels and getting more contiguous area under management. The WMP is addressed in this plan to provide a comprehensive view of the area and its importance. 3.2 Signage Signs denoting parcels as Conservation Land will be installed as contiguous parcels of 20 acres or more are acquired. 3.3 Easements, Concessions or Leases There are sixty -foot (60') platted right-of-way and utility easements dedicated to Collier County, along 41" Ave. NE, 39th Ave NE, and 371h Ave NE. No other easements, concessions or leases currently exist within Winchester Head. No other easements, concessions or leases are proposed for the future, and would not be permitted unless they further conservation objectives, such as a conservation easement. 3.4 Structures No structures are present on the parcels at this time. 3.5 Surrounding and Adjacent Land Uses Several single-family Golden Gate Estates zoned parcels — many of which have yet to be developed, surround Winchester Head. Everglades Blvd. North is west of the properties and the Faka Union canal is located to the east of the properties. 4.0 Interim Management Objectives 4.1 Natural Resource Protection Existing Vegetation: The following list identifies native plants observed during site visits: Swamp fern (Blechnum serrulatum), false nettle (Boehmeria cylindrica), arrowhead (Sagittaria spp.), sawgrass (Cladium jamaicense), royal fern (Osmunda regalis), pickerelweed 5 Packet Pg. 683 16.A.16.a February2023 Conservation Collier: Winchester Head Project Extended IMP (Pontederia cordata), cattail (Typha spp), buttonbush (Cephalanthus occidentalis), bald cypress (Taxodium distichum), willow (Salix spp.) and numerous species of native wetland grasses. Unique Natural Features: Winchester Head is comprised entirely of depressional cypress and marsh wetlands and therefore, provides habitat for wetland dependent species. Evidence onsite and data from the Southwest Florida Amphibian Monitoring Network 1 indicate that Winchester Head is used by wetland dependent species. Although it contributes only minimally to aquifer recharge, the area is a depressional feature in the landscape that holds water during the rainy season, enhancing water quality and offering flood protection to adjacent lands. Possible Listed Species: The observed habitat and location would support the presence of the following listed species: American alligator (Alligator misissippiensis), wood stork (Mycteria americana), limpkin (Aramus guarauna) and white ibis (Eudocimus albus). The Florida Fish and Wildlife Conservation Commission has documented Florida black bears (Ursus americanus floridanus) along the edges of the property. 4.2 Site Security At present, no known security issues exist within Winchester Head. Because Collier County currently owns 70 of the parcels, only some of which are contiguous, fencing will not be considered until a larger percentage of the parcels in the project area are acquired. 4.3 Exotic Vegetation Removal and Maintenance Plan Exotic vegetation removal at Winchester Head Preserve is currently targeted across 47 acres of the 95.8 acre preserve. Yearly treatment acreage has continually increased since acquisition, targeting the most infested parcels first. After the initial treatment of a parcel, the cost for subsequent treatments decreases, allowing for the treatment of additional parcels across the preserve. Exotic plant infestation across treated and non -treated parcels will continue to be monitored by Conservation Collier staff yearly, and subsequent treatment plans may be adjusted dependent on parcel infestation level and budgetary constraints. Problematic exotic species currently treated at Winchester Head Preserve are old world climbing fern (Lygodium microphyllum), Japanese climbing fern (Lygodium japonicum), Brazilian pepper (Schinus terebinthifolius), melaleuca (Melaleuca quinquenervia), and Peruvian primrose willow (Ludwigia peruviana). All infested areas within Winchester Head are treated during the dry season. All six parcels acquired through offsite mitigation donations came with management funds; these parcels have been treated on an annual basis since acquisition. ' The Southwest Florida Amphibian Monitoring Network represents a diverse group of citizen volunteers organized for the purpose of monitoring amphibians (mostly frogs) in southwest Florida Website: http://www.frogwatch.net/ 0 Packet Pg. 684 16.A.16.a February2023 Conservation Collier: Winchester Head Project Extended IMP 4.4 Cultural, Historical and Archeological Resource Protection Winchester Head is not within an area of historical and archaeological probability, and no historical or archaeological sites appear to be present in the property. The County will notify the Division of Historical Resources immediately if evidence is found to suggest any archaeological or historic resources are present within the Winchester Head project. If such properties 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 Collier County 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). The collection of artifacts or the disturbance of archaeological and historic sites within Winchester Head will be prohibited unless prior authorization has been obtained from the Collier County Board of County Commissioners and the Department of State, Division of Historical Resources. 4.5 Public Access Public access will not be addressed until a larger percentage of contiguous parcels within Winchester Head are acquired or parcels are consolidated, and a Final Management Plan is prepared. 4.6 Site Monitoring Plan Monitoring of the site shall consist of a walk-through by staff at bi-annual intervals. Any treatment and retreatment of exotic vegetation is dependent on the amount of contiguous acreage acquired. Conservation Collier shall be responsible for this treatment with tasks contracted out as deemed necessary. Prior to any land management activities, photo monitoring points will also be established at strategic locations within the project area to monitor vegetation communities. 4.7 Partnerships The South Florida Water Management District Big Cypress Basin may have interest in partnership and will be approached to determine interest. Conservation Collier will work closely with the Growth Management Division as the Watershed Management Plan projects come to fruition. 7 Packet Pg. 685 February2l 5.0 Exhibits EXHIBIT 1: Location Map 16.A.16.a Conservation Collier: Winchester Head Project Extended IMP Conservation Collier: Yfre Winchester Head Location Map c1r county LIMPKIN RD Z :J IMMOKALEE RD U 72ND AVE NE TRD RABBITRU-70TH AVE NE wz z T RD w 68TH AVE NE 0 w = WILD TURKEY DR 66TH AVE NE 64TH AVE NE 62NDAVE NE 60TH AVE NE 58TH AVE NE z 56TH AVE NE a m 54TH AVE N E w O 52NDAVE NE 0J z LU 50THAVE NE w z o F m z N � 47TH AVE NE48TH AVE NE_] _ w w w w w w w 47TH AVE NE o w z z z z z z z 45TH AVE NE z r i- r F F I- j- 1 U) N U) U) 0) N 45TH AVE NE T = O N V ~O ib r~D W N N N 43RD AVE NE 41STAVE NE 41STAVE NE 39TH AVE NE, _ 39TH AVE NE ti 37TH AVE NE G C.)37TH AVE NE i 35TH AVE NE n �p� O Q FAIRMONT LN 35TH AVE NE 33RD AVE NE OIL WELL RD GROVE DR— j PAR DR VERMON LT 0 0.375 0.75 1.5 Miles Data Source: Parcels - Collier County Property Appraiser Created oy.

The Winchester Head Project boundary encompasses 114 parcels totaling 157.53 acres. As of January 2023, 70 parcels or 95.8 acres (61%) have been acquired by Conservation Collier in a checkerboard fashion throughout the project area. The Collier Soil and Water Conservation District (CSWCD) owns two parcels totaling 2.28 acres within the project area. Conservation Deleted: Collier conducted a market study appraisal in 2022. �As of 2022, the Property Appraiser is valuing , Deleted: That market study included two appraisers with parcels within this area between $25,000 and $55,000 per acre depending on the size and percent average value for these parcels at $30,000 per acre. cover of wetlands. That market study included two appraisers with an average value for these parcels at $30,000 per acre. Conservation Collier is currently continuing to pursue the acquisition of all approved parcels within Winchester Head as means to do so present themselves. Conservation Collier has begun to make offers to owners submitting applications within Winchester Head utilizing funds from offsite preservation received as part of the Land Development Code's Off -Site Native Vegetation Retention Requirements (LDC Section 3.05.07H.l.f.iii.a). Additionally, offsite preservation parcels may be donated within this area (LDC Section 3.05.07H. Lfliii.b). Five parcels have been acquired as offsite mitigation donations since 2013 within the project area, and one additional parcel (1.14 acres) was donated to offset Code Enforcement Liens, for a total of 7.29 acres donated If additional properties cannot be acquired using the above means, or it becomes apparent that few properties can be acquired in this manner, Conservation Collier staff will seek to exercise a provision of the Conservation Collier ordinance (2007-65, Section 14.7 as amended) that allows for the exchange of lands within and between multi -parcel projects in accordance with the goals of the Program. The objective of any such exchanges will be to consolidate the areas owned by Collier County under the Conservation Collier program into one contiguous area. All acquired properties will be managed only for conservation, protection, and enhancement of natural resources and for public outdoor recreation that will be compatible with the conservation, protection, and enhancement of the site and its surrounding lands. Public use of the site will not be practical until more contiguous properties within Winchester Head can be acquired and a trail or boardwalk constructed, the boardwalk of which is not presently funded. This interim management plan is intended to update the key management priorities and issues within the site and give direction for management through 2025. This document is intended to be the precursor to a final management plan, which will provide more specific aspects of site management once a contiguous block of properties can be assembled. Packet Pg. 697 16.A.16. b February2023 Conservation Collier: Winchester Head Project Extended IMP Key Interim Management Objectives 1. Monitor vegetation until a contiguous block in the center of the project can be acquired which will trigger more extensive vegetation management actions. 2. Treat offsite donation parcels for invasive exotic plants on an annual basis. 3. Explore opportunities for grant funding and partnerships for management. Action Plan 1 a. Make bi-annual site visits to monitor the spread of Category I and II invasive plant species within parcels. Once a contiguous tract of the project is acquired, begin exotic plant management within this tract; Continue monitoring the remainder of parcels. lb. Treat all Category I and II invasive plant species within offsite mitigation donation parcels on an annual basis. 2a. Seek grant funding opportunities for the removal of exotic flora. 2.0 Management Authority and Responsibilities The Conservation Collier Program, part of the Collier County Parks & Recreation Division since October 2012, will be solely responsible for managing the Winchester Head parcels, but will also seek to obtain grants and form partnerships for management activities. 3.0 Interim Site Plan 3.1 Location and Site Description The Winchester Head Parcels are located east of Everglades Blvd. North, between 41' Ave NE and 35' Ave NE in Sections 8 & 17, Township 48 and Range 28 in Golden Gate Estates, Units 62 and 65 within Collier County, Florida. The southernmost parcels are located south of 37' Ave NE but do not extend to 35' Ave NE (Exhibits 1-5). The approximate center of the project is located at 26118'9.67"N and 81132'19.58"W. Winchester Head is comprised of Mixed Wetland Hardwoods (FLUCCS 617), Cypress (FLUCCS 621), Cypress, Pine, Cabbage Palm (FLUCCS 624) and Freshwater Marsh (FLUCCS 641). Compared to the higher elevations of the lands surrounding Winchester Head, from 18 to 24 feet above sea level, the natural depression of this cypress area (Exhibit 6) at 15-17 feet below sea level, combined with the presence of hydric, poorly drained soils allows for water to collect and slowly percolate into the ground. Thus, Winchester Head is ideal for obligate and facultative wetland plant and animal species. Conservation Collier's Winchester Head multi -parcel project is within the North Golden Gate Estates (NGGE) Flowway Restoration Project (Exhibit 7), which is an area of focus within the County's Watershed Management Plan (WMP). The goal of this project is to reconnect the historic flowway and redirect storm water drainage away from NGGE's canals, allowing it to move south toward North Belle Meade and naturally low county areas while allowing ground absorption along the way. As part of the WMP, a Phase I and Phase II analysis of the flowway, which includes Winchester Head, have been completed. The Phase I estimated that Winchester Head contains approximately 414.7 acre-feet of storage based on an average, water surface elevation of 16.0 feet (North American Vertical Datum of 1988). The goal of reconnecting wetland systems within the NGGE has been Packet Pg. 698 16.A.16. b February2023 Conservation Collier: Winchester Head Project Extended IMP incorporated into development of the County's Watershed Management Plan, approved by the Board of County Commissioners in December 2011. The WMP includes structural projects and policy initiatives, both of which would affect the Winchester Head area. Structural projects include adding culverts and other water management structures. Xolic Deleted: Policy initiatives include apotential TDR Pr initiatives include a potential Transfer of Development Rights (TDR) process and a and a watershed Mitigation Program. Watershed Mitigation Program. The TDR process provides an equitable method of protecting and conserving the most valuable environmental lands, including large, connected wetland systems and significant areas of habitat for listed species offish, plants, and wildlife, while allowing owners of such lands to recoup lost value and development potential through an economically viable process of transferring the development rights in such lands to other, more suitable lands. At present, no specific projects have been authorized. If Conservation Collier were to acquire and restore parcels within Winchester Head, this would serve WMP goals. However, the choice of projects determined for Winchester Head and north of Winchester Head within the flowway could affect how Conservation Collier approaches management. Structural projects could increase the volume of water stored within the WH project boundaries and thus alter proposed management actions, while a proposed TDR program could assist Conservation Collier in acquiring more parcels and getting more contiguous area under management. The WMP is addressed in this plan to provide a comprehensive view of the area and its importance. 3.2 Signage Signs denoting parcels as Conservation Land will be installed as contiguous parcels of 20 acres or more are acquired. 3.3 Easements, Concessions or Leases There are sixty -foot (60') platted right-of-way and utility easements dedicated to Collier County, along 41st Ave. NE, 39th Ave NE, and 371h Ave NE. No other easements, concessions or leases currently exist within Winchester Head. No other easements, concessions or leases are proposed for the future, and would not be permitted unless they further conservation objectives, such as a conservation easement. 3.4 Structures No structures are present on the parcels at this time. 3.5 Surrounding and Adjacent Land Uses Several single-family Golden Gate Estates zoned parcels — many of which have yet to be developed, surround Winchester Head. Everglades Blvd. North is west of the properties and the Faka Union canal is located to the east of the properties. 4.0 Interim Management Objectives 4.1 Natural Resource Protection Existin¢ Ve¢etation: The following list identifies native plants observed during site visits: Swamp fern (Blechnum serrulatum), false nettle (Boehmeria cylindrica), arrowhead (Sagittaria spp.), sawgrass (Cladium jamaicense), royal fern (Osmunda regalis), pickerelweed Packet Pg. 699 16.A.16. b February2023 Conservation Collier: Winchester Head Project Extended IMP (Pontederia cordata), cattail (Typha spp), buttonbush (Cephalanthus occidentalis), bald cypress (Taxodium distichum), willow (Salix spp.) and numerous species of native wetland grasses. Unique Natural Features: Winchester Head is comprised entirely of depressional cypress and marsh wetlands and therefore, provides habitat for wetland dependent species. Evidence onsite and data from the Southwest Florida Amphibian Monitoring Network ' indicate that Winchester Head is used by wetland dependent species. Although it contributes only minimally to aquifer recharge, the area is a depressional feature in the landscape that holds water during the rainy season, enhancing water quality and offering flood protection to adjacent lands. Possible Listed Species: The observed habitat and location would support the presence of the following listed species: American alligator (Alligator misissippiensis), wood stork (Mycteria americana), limpkin (Aramus guarauna) and white ibis (Eudocimus albus). The Florida Fish and Wildlife Conservation Commission has documented Florida black bears (Ursus americanus floridanus) along the edges of the property. 4.2 Site Security At present, no known security issues exist within Winchester Head. Because Collier County currently owns 70 of the parcels, only some of which are contiguous, fencing will not be considered until a larger percentage of the parcels in the project area are acquired. 4.3 Exotic Vegetation Removal and Maintenance Plan Exotic vegetation removal at Winchester Head Preserve is currently targeted across 47 acres of the 95.8 acre preserve. Yearly treatment acreage has continually increased since acquisition, targeting the most infested parcels first. After the initial treatment of a parcel, the cost for subsequent treatments decreases, allowing for the treatment of additional parcels across the preserve. Exotic plant infestation across treated and non -treated parcels will continue to be monitored by Conservation Collier staff yearly, and subsequent treatment plans may be adjusted dependent on parcel infestation level and budgetary constraints. Problematic exotic species currently treated at Winchester Head Preserve are old world climbing fern (Lygodium microphyllum), Japanese climbing fern (Lygodium japonicum), Brazilian pepper (Schinus terebinthifolius), melaleuca (Melaleuca quinquenervia), and Peruvian primrose willow (Ludwigia peruviana). All infested areas within Winchester Head are treated during the dry season. All six parcels acquired through offsite mitigation donations came with management funds; these parcels have been treated on an annual basis since acquisition. 1 The Southwest Florida Amphibian Monitoring Network represents a diverse group of citizen volunteers organized for the purpose of monitoring amphibians (mostly frogs) in southwest Florida Website: http://www.frogwatch.net/ Packet Pg. 700 16.A.16. b February2023 Conservation Collier: Winchester Head Project Extended IMP 4.4 Cultural, Historical and Archeological Resource Protection Winchester Head is not within an area of historical and archaeological probability, and no historical or archaeological sites appear to be present in the property. The County will notify the Division of Historical Resources immediately if evidence is found to suggest any archaeological or historic resources are present within the Winchester Head project. If such properties 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 Collier County 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). The collection of artifacts or the disturbance of archaeological and historic sites within Winchester Head will be prohibited unless prior authorization has been obtained from the Collier County Board of County Commissioners and the Department of State, Division of Historical Resources. 4.5 Public Access Public access will not be addressed until a larger percentage of contiguous parcels within Winchester Head are acquired or parcels are consolidated, and a Final Management Plan is prepared. 4.6 Site Monitoring Plan Monitoring of the site shall consist of a walk-through by staff at bi-annual intervals. Any treatment and retreatment of exotic vegetation is dependent on the amount of contiguous acreage acquired. Conservation Collier shall be responsible for this treatment with tasks contracted out as deemed necessary. Prior to any land management activities, photo monitoring points will also be established at strategic locations within the project area to monitor vegetation communities. 4.7 Partnerships The South Florida Water Management District Big Cypress Basin may have interest in partnership and will be approached to determine interest. Conservation Collier will work closely with the Growth Management Division as the Watershed Management Plan projects come to fruition.
