Modeling, Estimation, and Adaptive Management of Florida Manatees

The Challenge: Florida manatees are threatened by watercraft-related mortality, the potential loss of warmwater habitat, red tide events, and other anthropogenic factors. The USFWS and the Florida Fish and Wildlife Conservation Commission have regulatory authorities under the Endangered Species Act (ESA), the Marine Mammal Protection Act (MMPA), and state statutes to recover manatees. To...

Structured Decision Making for Management of Warm-Water Habitat of Manatees

Manatees are tropical to subtropical in distribution and, with few exceptions, Florida is the northern limit of their natural winter range.  The availability of warm-water habitat during winter is critical for the future persistence of the population in Florida.

Seagrass Beds and Manatee Foraging Areas in the Ten Thousand Islands: Mapping and Characterizing by Incorporating Manatee GPS Tracking Data and Habitat Information

Turbid water conditions make the delineation and characterization of benthic habitats difficult by traditional in situ and remote sensing methods. Consequently, only a small fraction of this valuable resource has been mapped or characterized.

Mangroves form a protective berm on a Florida Bay island

The transition between a mud flat on the interior of Bob Allen Key (Florida Bay, Everglades National Park) and the mangroves that form the islands’ protective outer berm.  These black mangroves have pneumatophores – parts of the root that function like snorkels, allowing the roots to “breathe” when water overlies the mud flat.

The storm resulted in large waves and elevated water levels that caused erosion in this area, as can be seen in the scarp forming at the vegetation line. CMHRP researchers surveyed the elevation of the beach before and after the storm to quantify the storm's impacts.
