Wildlife and Terrestrial Species
Wildlife and Terrestrial Species
We provide rigorous and unbiased information on migratory birds, terrestrial and marine mammals, amphibians and reptiles, native plants, threatened and endangered species, wildlife disease, and on wildlife issues resulting from human activities. Our science contributes toward a more complete understanding of the Nation’s ecosystems and landscapes.

Decision Science Support for SARS-CoV-2 Risk to North American Bats
The Eastern Ecological Science Center is working closely with federal, state, and tribal partners to help inform decisions that reduce the risk of SARS-CoV-2 transmission from humans to North American wildlife, including bats.
Understanding Greater Everglades Mammal Communities within and adjacent to the Arthur R. Marshall Loxahatchee National Wildlife Refuge
WARC Researchers are using a variety of methods to assess mammal communities across the Greater Everglades.
Strategic Habitat Conservation for Brown Pelican
WARC researchers partnered with managers and species experts to develop a Bayesian network model and a geospatial habitat characteristics dataset to predict the number of Brown Pelican breeding pairs on islands in the northern Gulf.
Strategic Habitat Conservation for Black Skimmer and Gull-billed Tern
WARC researchers partnered with managers and species experts to develop a Bayesian network model and a geospatial habitat characteristics dataset to predict the number of breeding pairs of Black Skimmer and Gull-billed Tern along the Northern Gulf Coast.
Strategic Habitat Conservation for Beach Mice (Peromyscus polionotus ssp.)
WARC researchers partnered with beach mice managers and biologists to estimate habitat objectives and the amount of effort needed to achieve the habitat objective (i.e., management efficiency) for three beach mice subspecies in Florida’s panhandle.
Pacific Pocket Mouse Monitoring and Research Program
Once thought to be extinct, the Pacific pocket mouse ( Perognathus longimembris pacificus) was rediscovered in 1993 and is currently found at three population sites along the southern California coast. USGS researchers and their partners developed a comprehensive long-term research and monitoring plan to assess the status and trends of Pacific pocket mouse and identify important drivers of...
Quantitative Tools for the Urgent Recovery and Regulatory Needs of the Florida Bonneted Bat, Eumops floridanus
WARC researchers are organizing Florida bonneted bat echolocation recordings into a database to assess population trends and bat response to management actions.
Biology, Impacts and Control of Invasive Reptiles in the Pacific
Research on Guam has led to development and validation of numerous effective control tools, including the advancement of reptile control to support native species recovery.
Desert Tortoise Ecology and Renewable Energy Development
The desert Southwest is experiencing rapid development of utility-scale solar and wind energy facilities. Although clean renewable energy has environmental benefits, it can also have negative impacts on wildlife and their habitats. Understanding those impacts and effectively mitigating them is a major goal of industry and resource managers. One species of particular concern is Agassiz’s desert...
Decision-support tool for managing endangered species in the face of uncertainty
Along the Santa Clara River in California, populations of the federally and state-listed Least Bell's Vireo ( Vireo bellii pusillus) are recovering from near extirpation. Habitat protection and restoration, as well as reducing brood parasitism by Brown-headed Cowbirds ( Molothrus ater), are thought to be the primary drivers of this recovery. The challenge going forward is to find the right balance...
Effects of Saltwater Intrusion on Anuran Occupancy in Big Thicket National Preserve, Texas
WARC researchers sampled anuran populations at sites within Big Thicket National Preserve to explore saltwater intrusion on these populations.
Acoustic Monitoring for Two Rare Frog Species in Northwest Louisiana
WARC researchers are using automated recording units to monitor southern crawfish frogs and Strecker's chorus frogs in Louisiana.
