Threatened and Endangered

The Bureau of Ocean Energy Management (BOEM) uses trawling to capture and relocate live sea turtles away from dredging locations to minimize the risk of turtle entrainment. These incidental turtle captures provide a unique opportunity to fill critical data gaps for difficult to capture life-stages of marine turtles.

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.

Using ecological and geographical data, WARC researchers and their partners are analyzing avian and benthic sampling on Whiskey Island and Caminda Headland to compare pre- and post-restoration aspects of habitat occupancy, habitat availability, habitat use, and kernal density estimation.

USGS works with partners to assess manatee distribution and habitat use throughout the Northern Gulf.

Researchers will collect location data that will be used to identify areas of high-use for resident sea turtles in the Florida Keys National Marine Sanctuary.

To assess use of dredge material areas, avian ecologists from USGS WARC are conducting bird surveys across the annual life cycle.

The Northwestern Atlantic population of loggerhead sea turtles is one of the largest in the world. Genetic studies have divided this population into 5 management units including a genetically distinct group that nests throughout the northern Gulf.

WARC will assess Cape Sable seaside sparrow population response and viability under different management and habitat change scenarios. The USGS EverSparrow model will be run on future scenarios, and differences in the predicted probability of presence and the efficacy of varying conservation strategies will be evaluated.

Mole skinks that occur on Florida’s islands rely on sand beaches, beach berms, and dunes, making them particularly vulnerable to sea level rise and storm surge. USGS researchers predicted the impacts of sea level rise and storm surge on habitat for the Florida Keys mole skink ( Plestiodon egregius egregius), the Cedar Key mole skink ( P. e. insularis), and the Egmont Key mole skink (known from a...

Researchers at WARC are determining if temporal mismatches between digital elevation models and land cover data can impact estimates of inundation of beach habitat for barrier islands and low-lying beaches off the Gulf Coast of Florida.

With the support of the Mote Marine Laboratory and Aquarium, USGS researchers will develop and optimize a CRISPR biosensor to detect C. galea eDNA in the field. The development of this tool could assist coral restoration managers and stakeholders to more effectively inform decisions on coral outplant site selection, based on coral predator presence.

USGS researchers will collect data on salinity, water level, and flooding duration within Big Branch National Wildlife Refuge to improve the understanding of the hydrologic system, and how hydrology drives available red-cockaded woodpecker habitat use and availability across the landscape.
