Predicting Effects of Hydrologic Restoration on Manatees along the Southwest Coast of Florida

Project Investigator: James P. Reid Project Personnel: Brad Stith, Susan Butler Project Start Date: 2000 End Date: 2005 Recent Funding: (FY05) USGS GE PES Work Plans Project Summaries Metadata Publications Project Location Map

The U.S. Geological Survey initiated a study on the impacts of hydrological restoration on manatees in the Ten Thousand Islands region in June 2000. The major objectives of the study are to determine distribution, movements, and habitat use of manatees associated with coastal waters and rivers, and to develop a population-level model to predict manatee response to changes in hydrology achieved by the Southern Gold Gate Estates (SGGE) project specifically, and more broadly by the Comprehensive Everglades Restoration Plan. This project obtains results via: strip-transect aerial surveys, satellite telemetry, and tracking of individuals using a specially-designed Global Positioning System (GPS) tag.
