Project Description:
(Up to 250 words)
The volunteers working on invasives at the Hobe Sound NWR have remained fairly stable and have included representatives of the Florida State Parks, The Nature Conservancy, the Marine Resources Council, Martin County and the Florida Oceanographic Society. We have rotated our efforts into areas of greatest need including wetland fringe and coastal dune habitats. Species primarily targeted were Australian pine and Brazilian pepper. We have shared expertise and knowledge of invasive species issues and have received good media coverage including articles in the Palm Beach Post and the Stuart News. A Memorandum of Understanding has been prepared between key agencies and partners that cements this partnership and fosters continued working relationships. This year the refuge became part of the newly formed Treasure Coast Cooperative Invasive Species Management Area that will carry on partnering in an effort to restore native habitats.

List both new and existing partnerships utilized in this project. (Up to 150 words).
An existing partnership with a signed Memorandum of Understanding exists for on the ground habitat restoration through rotating monthly work days between the Hobe Sound NWR, Florida State Parks, The Nature Conservancy, the Marine Resources Council, and Martin County. This partnership has caught the interest of other surrounding agencies and has sparked interest in creating a Treasure Coast Invasive Species Management Area (TC CISMA). The TC CISMA will work to restore habitats across boundary lines. Other governmental and non-governmental agencies have shown interest in joining the TC CISMA including the Florida Fish and Wildlife Commission, Florida Power and Light, and the Florida East Coast Railroad as well as private land owners. The HSNWR is very proud to be part of this group and looks forward to landscape level habitat restoration efforts to come.


Project Results:
Give an overview of the results of the project. Include quantifiable measure of success, such as maps produced, efficacy of control measures, number of sites where invasions were detected early and responded to, number of community contacts, etc. (Up to 250 words).
The Hobe Sound NWR worked on three projects on Jupiter Island with the $10,000 Volunteers Working with Invasives grant funding. The primary targets were Australian pine and Brazilian pepper. Each project area was approximately 10 acres. Two of the sites or 20 acres were early detection rapid response projects and one site or 10 acres was a project heavily infested with invasive plant species. Each of these sites was mapped to define the habitat restoration area. Garlon 4® and Rodeo® were used to treat the invasive plant species on all 30 acres. The two sites treated for early detection rapid response were very successful and will require little re-treatment. The heavily infested site will need to have routine re-treatment to fully restore the site. The heavily infested site was adjacent to homes and the Town of Jupiter Island was contacted to inform them about the restoration project. The heavily infested site required heavy equipment including front end loaders and a gyro-trac as well as native plants to restore the area. Volunteers were used throughout the process to coordinate the effort, install native plants, remove smaller invasive plants, and perform one re-treatment effort of the heavily infested site. For all projects a licensed pesticide applicator was present to ensure quality control for chemicals used.
Number of Acres Treated: 30
Number of Acres Inventoried and/or Mapped: 30
Number of Acres Restored: 20 - Re-treatment still needed on 10 acres.


Budget: Account for funds in broad categories such as equipment, volunteer stipends, travel, coordinator salary/contract, etc.
