Study Title: Predicting Effects of Hydrologic Restoration on Manatees along the Southwest Coast of Florida
Associated / Linked Studies: Linkages to other projects/databases include TIME model, ATLSS model, and the associated PBS projects: Impacts of Hydrological Restoration on Three Estuarine Communities of the Southwest Florida Coast and on Associated Fauna (Carol McIvor) (http://sofia.usgs.gov/projects/impacts_est/); Southwest Florida Coastal and Wetland Systems Monitoring Project (E. Patino) (http://sofia.usgs.gov/projects/sys_monitor/) Additional information on Predicting Effects of Hydrologic Restoration on Manatees along the Southwest Coast of Florida is available on the Sofia website: http://sofia.usgs.gov/projects/manatees/
Overview & Objective(s): Determine relative abundance, distribution, movements, and habitat use of manatees associated with coastal waters and rivers from Marco Island through Whitewater Bay. Identify resources critical to manatees in the region, including distribution and abundance of submerged aquatic vegetation and freshwater drinking sites. Develop an individual-based ATLSS model to predict manatee response to changes in hydrology achieved by the Southern Golden Gate Estates (SGGE) project specifically and more broadly by the Comprehensive Everglades Restoration Plan. Additional information on population trend, distribution, and habitat use, coupled with models of hydrology, bathymetry, aquatic vegetation, and salinity, will allow development of a population-level model capable of predicting their response to future changes. This SGGE modeling effort will provide invaluable information as a small-scale test case for understanding and predicting how restoration efforts in the Everglades will affect manatees.
Status: On track for completion in FY05

Specific Relevance to Information Needs Identified in DOI's Science Plan in Support of Ecosystem Restoration, Preservation, and Protection in South Florida (DOI's Everglades Science Plan) [See Plan on SOFIA's Web site: http://sofia.usgs.gov/publications/reports/doi-science-plan/]:
This study supports two of the projects listed in the DOI science plan, including: Southern Golden Gate Estates Hydrologic Restoration, and Landscape-Scale Modeling.
The study supports the Southern Golden Gate Estates Hydrologic Restoration project (SGGE; p. 51) by 1) modeling predicted changes in hydrology and ecology in the Ten Thousand Islands NWR (p. 59), and 2) providing baseline data and monitoring of effects on a federally listed species, the West Indian manatee, within the Ten Thousand Islands NWR (p. 59-60).
The study supports the Landscape-Scale Modeling (LSM; p. 80-81) by 1) providing an individual-based demographic model of a threatened species, the West Indian manatee (p. 80), and 2) by providing Landscape-scale monitoring and assessment for MAP (p. 81, 90).
This study also supports the CERP Monitoring and Assessment Plan, Part 1, Southern Estuaries Module, Section 188.8.131.52: Manatee Abundance and Distribution Relative to Freshwater Input (pp. 3-98 - 3-100).
This study also supports the Planning Aid Report, Multi-species Conservation under Comprehensive Everglades Restoration Plan (CERP), Project 30, Southern Golden Gate Estates Hydrologic Restoration Project (pp. 252-254, 262-264).
Each manatee project task addresses a number of USGS project tasks related to hydrology, habitats and species, ecological indicators, and threatened and endangered species. Because the manatee is a federally listed species, our work supports a variety of needs identified by the DOI for listed species.
