Imperiled Species
Imperiled Species
Generally speaking, imperiled species are those animals and plants that are in decline and may be in danger of extinction. While some species are federally protected under the Endangered Species Act, many species are not due to the lack of knowledge regarding their status and the environmental factors that may threaten their future.

Evaluating Efficacy of Stewardship Actions for Vulnerable Gulf of America Coastal Birds Through Co-Production Between Scientists and Resource Managers
The USGS and partners will survey bird and human activity on beaches in Alabama, Mississippi, and Louisiana to determine breeding bird response to stewardship activities aimed at protecting and recovering bird populations.
Coastal Prairie Restoration at WARC Supports Ecological Biodiversity and Provides an Opportunity for Education
The USGS Wetland and Aquatic Research Center (WARC) has created a refuge for biodiversity in Lafayette, Louisiana, through the restoration of coastal prairie, a unique and vital ecosystem that has almost vanished within the last 100 years.
Winter Shorebird Surveys of Federally Protected Bird Species Following Restoration at West Belle Headland and Trinity-East Island, Louisiana
The USGS and the Barataria-Terrebonne National Estuary Program (BTNEP) conducted post-restoration monitoring of Piping Plovers and Red Knots to better understand how birds respond to coastal restoration.
Tracking Non-breeding Habitat Use by Dunlin, Pectoral Sandpipers, and Other Migratory Shorebirds in the Mississippi Delta
USGS researchers and heir partners are capturing and banding birds that use man-made habitats to gather data on species occurrence, abundance, and energetic condition during autumn migration.
Population Ecology of Florida Manatees
USGS is working with partners to understand how the federally protected Florida manatee ( Trichechus manatus latirostris) population changes over time and responds to threats.
Avifauna Surveys of the Northern Main Chandeleur Islands
USGS WARC ecologists are assisting partners in conducting avian surveys on Chandeleur Islands during the pre-restoration monitoring phase to document threatened and endangered species, species richness and diversity, species abundance, and habitat use.
Management of Gopher Tortoise (Gopherus polyphemus) Using Coastal Habitats
USGS researchers are conducting research on St. Vincent National Wildlife Refuge and throughout coastal habitat in Northwest Florida to inform future management decisions in the Refuge and contribute to the growing knowledge of the ecology of gopher tortoises using coastal habitats.
Monitoring Effects of Barrier Island Restoration on Piping Plovers in Louisiana
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.
Trawling and Sea Turtle Capture Records: A Collaborative Effort between USGS and the U.S. Army Corps of Engineers
USGS is partnering with U.S. Army Corps of Engineers to digitize 20 years of historic sea turtle relocation trawling reports from over 50 sites across nine states.
Distribution and Density of Sea Turtles in the Gulf: Gulf of America Marine Assessment Program for Protected Species (GoAMAPPS)
The over-arching goal of GoAMAPPS is to collect broad-scale survey data for seabirds, marine mammals and sea turtles to determine distribution and abundance in the Gulf.
Sturgeon Occurrence and Behavior in the Outer Continental Shelf
A new study aims to collect information on sturgeon temporal and spatial distribution to inform offshore wind energy and sand leasing operations.
Beach Compaction and the Impacts of Tilling on Nesting Sea Turtles and Foraging Shorebirds
Researchers are investigating beach compaction, the incubation environment for turtle nests, and shorebird nest abundance at beaches throughout the southeastern United States to better understand the impacts of beach compaction to nesting turtles and foraging seabirds.
