American Alligator

2016 (approx.)

Detailed Description

USGS and other scientists have studied in-depth alligator populations in Florida and Louisiana, but basic ecological knowledge is lacking for populations at the northern edge of their range. For example, differences in climate and habitat between the southern and northern portions of the range limit the applicability of findings from other studies to South Carolina alligator management.

South Carolina alligators occupy a patchwork of diverse habitats, including rivers, lakes, wooded swamps, tidal marshes, and impounded freshwater wetlands. As a mobile, opportunistic predator, alligators seasonally adjust their habitat use for feeding. For example, some Florida alligators venture into brackish water habitats to feed on nutrient-rich blue crabs during the wet season because increased rainfall reduces salinity levels, making the water more tolerable to the gators.
