Project Description:
(Up to 250 words)
Refuge staff have identified two small populations (~ 0.25 acres) of air potato (Dioscorea bulbifera) and three populations (~ 2.5 acres) of life plant (Kalanchoe pinnata) within the subtropical hardwood hammock habitat of the refuge. Both of these non-native invasive plants are identified by the Florida Exotic Pest Plant Council as having adverse impacts on Florida’s biodiversity and native plant communities. The refuge proposes to eradicate these populations with two Early Detection Rapid Response projects. With staff supervision, volunteers will inventory and map the sites, eradicate the plant populations (hand pulling and herbicides), and monitor the plant control success with site visits at 3,6,12, and 24 months post-treatment.

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).
Volunteers have completed initial treatments at 2 life plant sites and 2 air potato sites. Volunteers are expected to complete additional (2 life plant and 1 air potato) projects by 12/15/2010. 3 mapping projects are currently in progress, with a total of 5 mapping projects expected at project completion. 1 previously undiscovered Madagascar periwinkle population was found and completely treated. 1 previously undiscovered bowstring hemp population was found and mapped, and is slated for initial treatment 03/01/2011.
Number of Acres Treated: 1.75
Number of Acres Inventoried and/or Mapped: 15
Number of Acres Restored: 1.75
