Exhibit "D" or uncommon within the state) by the Florida Natural Areas Inventory, restoration should be the long- term goal for its management. Restoration of the community by continued removal and control of exotic plants and mechanical/chemical restoration efforts by roller -chopping and herbicide treatment will be implemented when funding or mitigation opportunities become available. Exotic Species Removal, management and control of FL EPPC Category I and II invasive exotic plant species, including Brazilian pepper, air potato vine and Australian pine has been the primary management activity at ORCA since the original acquisition in 1991. Given the large invasive plant seed sources surrounding the conservation area, eradication of exotics will not be possible, but management control is feasible. The control of these invasive species requires a long-term commitment of labor resources, which will depend on volunteer support from the local community. Over the next five years, County staff will direct upland mitigation funds to the ORCA project when possible, and will seek additional funding from the Bureau of Invasive Plant Management of the Florida Fish and Wildlife Conservation Commission. Priority areas for future exotic species removal are the remaining stands of Australian pines along the property boundary in the southwestern portion of the original ORCA property, and the three remaining stands located on the Flinn Tract. County staff will continue coordination with the IRCMCD for continued control and removal of Brazilian peppers associated with the mosquito impoundment dikes. Planting of native species appropriate to the original natural community or to existing elevation and hydrological conditions of each site will follow removal of large stands of exotic plants, as appropriate. Cultural Resource Protection The archaeological sites on the ORCA property are relatively intact. Two potential threats to these sites are disturbance associated with construction of recreation access and scavenging by amateur archaeology enthusiasts. For these reasons, existing recreational improvements on the have been carefully located so as not to result in construction disturbance of the archaeological sites, and located so as not to promote easy public access to the sites for unauthorized scavenging. On the Flinn Tract, reconnaissance -level archaeological surveying of proposed development sites will be included in design of future improvements or mitigation projects. The Florida Department of State, Division of Historical Resources will be provided with findings of that preliminary survey, and will review development plans. DHR will also be consulted regarding any additional management actions needed to protect potential cultural resources on the Flinn Tract. Cultural resource protection strategies will include the identification and report to the Indian River County Sheriffs Office and DHR of any activities detrimental to known cultural sites. New sites will be submitted to DHR for inclusion in the Florida Master Site File as they are identified. 15
