The Utah Cooperative Fish and Wildlife Research Unit is leading an integrated resource assessment, inventory and monitoring of pygmy rabbit and other wildlife in the shrubsteppe habitat in Utah.

South Carolina alligators occupy a patchwork of diverse habitats, including rivers, lakes, wooded swamps, tidal marshes, and impounded freshwater wetlands. As a mobile, opportunistic predator, alligators seasonally adjust their habitat use for feeding.

The Wyoming Cooperative Fish and Wildlife Research Unit is located in the University of Wyoming’s Zoology and Physiology Department, where staff scientists are funded through the USGS. The Wyoming CRU is part of the nationwide Cooperative Research Unit Program, and we have a commitment to species and issues that are central to Wyoming and the Rocky Mountain West.

The Colorado Plateau of western North America is home to numerous localized and rare populations of plant species, many of which are listed under the Endangered Species Act. The conservation and management challenge, then, is to design strategies that allow access to energy on public lands while maintaining healthy populations of the co-located plant species.&n

Up to 800 pelicans are seen on Utah’s Strawberry Reservoir each summer as they gather in shallow areas and the mouths of its tributaries to catch fish. Anglers and managers are concerned about the impact the pelicans might have on the cutthroat trout population.  As such, Dr. Phaedra Budy, unit leader of the U.S.

Beaver Creek is an unburned stream adjacent to the Twitchell Fire that provides a reference for how burned streams might otherwise look.

Virginia Cooperative Fish and Wildlife Research Unit hosts a field trip to Rock Creek Park in Washington, DC to learn more about northern long-eared bats.

Scientists with the USGS Utah Cooperative Fish and Wildlife Research Unit are leading research on Utah’s native fish, the Bonneville cutthroat trout, a fish feared extinct in the 1970s. Researchers have monitored for fish abundance, density, distribution, size and age for nearly two decades.

Reports of golden eagle mortality linked to wind energy facilities are cause for concern especially when coupled with the knowledge that golden eagles move great distances between breeding and wintering areas. Mortalities at a particular wind energy facility can consequently affect breeding populations of golden eagles at local and continent-wide scales.

Many field projects are in remote locations and accessible by all-terrain vehicles. The Wyoming Cooperative Fish and Wildlife Research Unit is in the University of Wyoming’s Zoology and Physiology Department, where staff scientists are funded through the USGS. The researchers explore species and issues that are central to Wyoming and the Rocky Mountain West.

Cerulean warblers breed in mature deciduous forests throughout the eastern U.S., but are particularly abundant in oak-dominated forests that contain canopy gaps and a complex canopy structure.

The Colorado Plateau of western North America contains large energy reserves under current or proposed development.  The region is also home to numerous localized and rare populations of plant species, many of which are listed under the Endangered Species Act. Our conservation and management challenge, then, is to design strategies that allow access to ene

USGS and other scientists have studied in-depth alligator populations in Florida and Louisiana, but basic ecological knowledge is lacking for populations at the northern edge of their range.

South Carolina alligators occupy a patchwork of diverse habitats, including rivers, lakes, wooded swamps, tidal marshes, and impounded freshwater wetlands. As a mobile, opportunistic predator, alligators seasonally adjust their habitat use for feeding.

Student volunteers are trained to scan historic library materials. The materials can be complex, consisting of multiple parts.
