Agenda 03/25/2008 Item #16E 2 Agenda Item No. 16E2 March 25, 2008 Page 1 of 10 EXECUTIVE SUMMARY Recommendation to authorize the County Manager, or his designee, to submit a Bureau of Invasive Plant Management (BIPM) grant proposal to the Florida Department of Environmental Protection (FDEP) for $132,000 to fund an invasive, exotic plant removal project at the Conservation Collier Railhead Scrub Preserve. OBJECTIVE: To have the Board of County Commissioners (BCC) authorize the County Manager, or his designee, to submit a proposal to the FDEP to fund an invasive, exotic plant removal project at the Railhead Scrub Preserve. CONSIDERATIONS: The Upland Plant Management Section of the BIPM funds individual invasive plant removal projects on public conservation lands throughout the State. If the grant is received, the BIPM will pay state contractors for work that will be performed on the Railhead Scrub Preserve property. No funds will be transferred to Collier County. Staff anticipates that a formal agreement between the BCC and the State will be needed before the project can proceed. Once an agreement is finalized, staff will return to the BCC for formal acceptance of the grant award and execution of the agreement. FISCAL IMPACT: The total cost of the project is $132,000. Collier County is requesting $102,000 in FDEP contractor services. The County will provide a $30,000 cash match towards invasive, exotic vegetation maintenance. County cash match is available within the Conservation Collier Management Fund 174 budget. GROWTH MANAGEMENT IMPACT: This proposal supports Objective 7.3 of the Conservation and Coastal Management Element of the County Growth Management Plan, which requires the County to continue to implement programs that conserve and protect endangered and threatened wildlife species. LEGAL CONSIDERATIONS: Approval of this grant application submittal conforms to the County's Grant Coordination procedures. RECOMMENDATION: Recommend that the Board of County Commissioners authorize the County Manager, or his designee, to submit the attached Railhead Scrub Preserve grant proposal to the FDEP BIPM.

Agenda Item No. 16E2 March 25, 2008 Page 4 of 10 SCOPE OF WORK: Proiect Location The Railhead Scrub Preserve is located in the Northwest corner of Collier County, Florida in Sections 10 and 16, Township 48 South, Range 25 East (See Map I). This I 35-acre preserve is management by the Collier County Conservation Collier Program. Proiect Description In 2007, large stands of melaleuca were mowed within a 13.5 - acre area of the preserve by a DEP contractor under a BIPM melaleuca project. Additionally, funds from USFWS Partners for Fish and Wildlife Program have been used to treat the surrounding areas. This project proposes treating the remaining 121.5 acres of the preserve that contain varying densities of exotic plants. A large majority of the Railhead Scrub Preserve is xeric oak scrub habitat containing few exotic species; however, the main target areas consist of hydric pine flatwoods, pine flatwoods and cypress areas that have been invaded by lygodium, Austrailian pine, Brazilian pepper, melaleuca, earleaf acacia, downy rosemyrtle, and carrotwood. Approximately 13.7 acres are heavily infested (90%-95% density) and can be removed with mechanical mowing along the western and southern edges (ZONE I). Approximately 13.7 acres of the preserve contain dense exotics (85%-90% density) that are not accessible with machinery. These areas (ZONE 2) will be treated in place. The remaining 105.5 acres (ZONE 3) will need to be swept for scattered exotic plants (10% density) that will be treated in place (See Maps 2 and 3). Work Specifications The contractor will be responsible for the control of any target trees and seedlings and the application of any herbicides within the designated target areas. All aspects of the control of FLEPPC Category I and 2 plants within the Railhead Scrub Preserve, including any equipment, labor, supply, and herbicide needs, will be the responsibility of the contractor. The contractor will take precautions to avoid harming any native vegetation or wildlife. ZONE 1 Exotics within ZONE I will be mechanically mulched using heavy machinery, such as a Brontosaurus or Hydro-ax. After stumps are cut, they will be treated with an appropriate herbicide per label rates, or the contractor will return within three months ofremoval to treat re-growth with an appropriate herbicide per label rates. Lygodium within this zone that is growing into native trees will be treated via the "poodle-cut" method. ZONE 2 Melaleuca and downy rosemyrtle within ZONE 2 will be cut down and their stumps will be treated using an appropriate herbicide per label rates. Melalueca will be chopped into 4 - foot sections and piled. All other exotic vegetation can be treated in place basally using an appropriate herbicide per label rates. 2 Agenda Item No. 16E2 March 25. 2008 Page 5 of 10 ZONE 3 All large trees> 4 ft. dbh will be treated in place basally or frill and girdle using an appropriate herbicide per label rates. All small trees and seedlings will be treated in place basally or cut stump treated using an appropriate herbicide per label rates. Other Requirements and Provisions Heavy equipment may only operate along established trails within the preserve or within ZONE 1. In pine flatwood areas where gopher tortoises may be present, Facilities Management staff will conduct surveys prior to exotic removal. Heavy equipment will remain at least 25 feet from any gopher tortoise burrow. A SFWMD Environmental Resource Permit is not required for this project. A Collier County Vegetation Clearing Pernlit will be obtained for this project. Proiect Time Frame The project must be completed during the latter portion of the dry season (normally late March - early June). Some sections of the mechanical removal will take place within a seasonally wet area. 3 Agenda Item No. 16E2 March 25, 2008 Page 6 of 10 Fundinl! Information Estimated Total Project Cost = $132,000 State Funding Desired = $102,000 - Initial treatment Matching Funds = $30,000 - Maintenance treatment for 2 years after initial treatment. Budget based on 2007 mowing project on southern Railhead Scrub Preserve and similar treat in place proj ects. 4 Agenda Item No. 16E2 March 25, 2008 Page 7 of ,oJ PROPOSAL INFORMATION: Conservation Land Qualification This property was purchased by Collier County with funds from the Conservation Collier Program. It is listed in FNAl Florida Conservation Lands. Abilitv to Maintain Site After Initial Treatment Funding for maintenance is available within the Conservation Collier budget. Zones 1 and 2 will be treated quarterly for the first year after treatment and semi-annually for the second year if control has been successful in the first ycar after treatment. Zone 3 will be treated on an as needed basis. Restoration Plan for Native Plants Native plants from the site and the surrounding lands should be an adequate seed source to re-vegetate the area. Because the site is within a managed preserve with few exotic upland plants present, no replanting efforts are being planned at this time. Threatened or Endangered Species or Habitats A large gopher tortoise (Gopherus polvphemus, SSe) population currently inhabits the scrub areas of the preserve. Other probable listed species within the preserve include: Gopher Frog (Ran a areolata, SSe), Eastern Indigo Snake (Diymarcher cora is, T), Bald Eagle (Haliaeetus leucocephalus) and Woodstork (Mvctcria americalla). Public Education Program The site was purchased as a Conservation Collier property. Public access is an important aspect of the Conservation Collier Program. Future plans for the site after exotic vegetation removal inc\udc: benches, picnic tables, and educational signs containing information pertaining to both native and invasive exotic vegetation. 5 MAP!
