Wildlife and Terrestrial Species

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.

Agricultural lands account for more than 50% of the lower 48 states and the effects of agricultural land use reach beyond individual fields and farms affecting terrestrial and migratory wildlife. Thus, it is important to know what long-term benefits US Department of Agriculture (USDA) conservation programs and policies have on wildlife habitat and the American public. The USDAs Conservation...

The North American Breeding Bird Survey (BBS) is the primary source for critical quantitative data to evaluate the status of continental bird species, keeping common birds common and helping fuel a $75 billion wildlife watching industry. Each year thousands of citizen scientists skilled in avian identification collect data on BBS routes throughout North America allowing us to better understand...

Many of Hawai‘i’s forest birds have shown significant declines in the past 200 years, with many currently listed as endangered species. Multiple threats have been identified as contributing to declines, including disease, invasive species, habitat loss, and decreased survivorship and productivity caused by introduced predators. Through a combination of demographic information, population modeling...

The Southwest Montana Sagebrush Partnership (SMSP) team, including land managers, landowners, and scientists, is implementing conifer removal projects encompassing over 55,000 acres of private, state, and federal lands throughout the region. To date, little place-based information exists regarding likely vegetation and bird responses to such treatments in Southwestern Montana. To address this...

Researchers at USGS are using historical wild horse survey and monitoring records to conduct a study of horse density across sagebrush ecosystems of the western United States. Researchers will develop generalized density maps for the species that will enhance concurrent evaluations into the ecological effects of wild horse populations.

Welcome to the Alaska Landbird Resource Information System, the official web site for Boreal Partners in Flight! Thanks for taking the time to learn more about the Boreal Partners in Flight program and our efforts to understand and conserve northern populations of landbirds.

The warming climate has the potential to drive significant changes in the health and energetics of Arctic fauna, particularly those dependent on sea ice habitats like polar bears. An animal’s health and energetic state reflects the interaction between its behavioral choices and the environment. Because of this, measuring changes in health and energetics has potential for revealing important...
