Blue grosbeak is one of many bird species strongly tied to riparian areas in the Southwest (photo compliments of U.S. Fish and Wildlife Service).

Impacts of invasive trees on nesting birds in riparian areas

Dependency of some sensitive bird species on invasive tree species for nesting raises concern about removing these exotic trees for wildfire control (photo compliments of U.S. Fish and Wildlife Service).
Ferruginous hawk fitted with a GPS transmitter.

Response of ferruginous hawks to energy development

Researchers fitted ferruginous hawk with GPS transmitters to study their movements relative to oil, gas, and wind energy development.

Populations and habitat of Rocky Mountain fisher

Researchers are building models to predict fishers’ current habitat at a broad scale, as well as potential future habitat under climate change scenarios (photo by Michael Schwartz).
Habitat of the greater sage grouse is increasingly fragmented due to housing development and resource extraction.

Gene flow among breeding areas of greater sage-grouse

Habitat of the greater sage grouse is increasingly fragmented due to housing development and resource extraction, with implications for gene flow among core breeding areas.

The Wildlife and Terrestrial Ecosystems program is engaged in sustaining species and ecosystems of concern through integrated and multidisciplinary research. The program investigates ecological interactions within and between aquatic and terrestrial plant and animal communities, social and economic values associated with consumptive and non-consumptive uses of fish and wildlife, management of terrestrial and aquatic habitats, and outcomes of land and water uses and natural disturbances on wildlife populations and habitats.
