Fiscal Year 2003 Project Summary Report
Project Title: American Alligator Ecology and Monitoring for CERP
Project Start Date: 2003 Project End Date: 2006
Location (Subregions, Counties, Park or Refuge): Greater Everglades Ecosystem
Funding Source: USGS's Greater Everglades Science Initiative (PBS), CESI
Project Personnel: Andy Maskell, Rena Borkhataria
Supporting Organizations: University of Florida, USDA Forest Service
Associated / Linked Projects:
Overview & Objective(s): Many important questions concerning the effects of Everglades restoration on alligator populations remain unanswered such as the impacts of decompartmentalization, the role of alligator holes as aquatic refugia, and the effects of hydrology on population growth and condition. Further, the methods for monitoring and evaluating restoration success are not clear or have not been adapted for use during CERP. Also, we need to continue to update and validate restoration tools such as population models for use in alternative selection, performance measure development, and prediction. This project will directly address the questions outlined above, develop monitoring methods, and validate restoration tools for use in CERP.
Status: We are continuing to provide parameter information to the ATLSS alligator population model. We are adding to our information concerning the impacts of canals on alligator populations with investigations into alligator production. We have established monitoring of alligator population growth, condition, and size distribution throughout the Greater Everglades. The final areas to be added, WCA3B and Big Cypress National Preserve, are scheduled to be added this FY. The ATLSS Alligator Production Index is now available for use in the restoration process but is also undergoing further calibration, validation, and updating with new data. The ATLSS Alligator Population Model has been completed and has undergone initial expert review, calibration, and validation. Both models are fully functional and available for use in comparison of restoration alternatives.
Recent & Planned Products: In FY02, 2 peer-reviewed journal articles, 2 papers in an international conference proceedings, and 1 book chapter were accepted for publication. We also gave several presentations at National Meetings and GEER in FY03 and 3 other manuscripts were submitted to peer-reviewed journals.
