Threatened and Endangered

USGS assesses how federally endangered sea turtles use the habitat in and around a no-take area in the Dry Tortugas National Park.

The federally threatened piping plover relies on sand-beach habitat year-round for nesting, foraging, and roosting, habitat that is particularly vulnerable to loss and degradation from coastal development, recreation activities, erosion, and sea-level rise.

The federally protected Atlantic Coast Piping Plover relies on habitats that were affected by Hurricane Sandy. USGS works to understand how these changes have affected nesting habitat and the reproductive success of the shorebird.

Climate change may reduce the suitability of nesting and foraging habitat used by federally threatened and endangered species, like the Loggerhead sea turtle.

USGS researchers tag and track endangered and threatened sea turtles to inform adaptive management strategies in marine protected areas.

Satellite/GPS tags help USGS researchers understand the movements of American Alligators and American Crocodiles in the Greater Everglades.

USGS researchers evaluate the impact of a pesticide on two imperiled butterfly species in the Florida Keys.

USGS scientists investigate adaptive habitat conservation for Flatwoods salamanders.

The Striped Newt is a small salamander found in xeric habitats (e.g., scrub, sandhill, dry flatwoods) of the lower coastal plain and northern peninsular Florida. Though once considered "common," they are currently a candidate species for federal listing.

The southeastern United States is home to a variety of freshwater snails, mussels, crayfish, and fishes. USGS scientists are conducting systematic studies to better document the region's biodiversity.

The decline of freshwater animals has resulted in an increase in the number of imperiled species and extinctions. USGS scientists use genetics to determine if these species truly are gone forever.
