Forest and Rangeland Ecosystem Science Center
Home
Scientists from the Forest and Rangeland Ecosystem Science Center capitalize on their diverse expertise to answer scientific questions shaped by the environments of the western United States. We collaborate with each other and with partners to provide rigorous, objective, and timely information and guidance for the management and conservation of biological systems in the West and worldwide.
FRESC Research Teams
FRESC scientists, individually or collaboratively with partners, investigate high-priority questions about biological systems.

Assessing Consequences of Human Activity on Wildlife Populations
Human activity sometimes stresses or kills individual animals. Most of the tools we have to address this problem are focused on those individuals. We have limited ways to understand how human activity impacts wildlife populations. USGS scientists have developed a new tool to help managers understand the effects of human stressors on wildlife populations.
Conservation Genetics of the Imperiled Striped Whipsnake in Washington
The striped whipsnake occurs across 11 western U.S. states and into Mexico but has experienced population declines in parts of its range, particularly in Washington.
Annotated Bibliography of Scientific Research on Greater Sage-Grouse Published
The U.S. Geological Survey has reviewed and summarized the substantial body of literature related to the conservation, management, monitoring, and assessement of the greater sage-grouse, creating an annotated bibliography that provides easy access to sage-grouse science developed since 2015.

Monitoring wetland water quality related to livestock grazing in amphibian habitats
Land use alteration such as livestock grazing can affect water quality in habitats of at-risk wildlife species. Data from managed wetlands are needed to understand levels of exposure for aquatic life stages and monitor grazing-related changes afield. We quantified spatial and temporal variation in water quality in wetlands occupied by threatened...
Smalling, Kelly; Rowe, Jennifer; Pearl, Christopher; Iwanowiczl, Luke R.; Givens, Carrie E.; Anderson, Chauncey W.; Mccreary, Brome; Adams, Michael J. From satellites to frogs: Quantifying ecohydrological change, drought mitigation, and population demography in desert meadows
Increasing frequency and severity of droughts have motivated natural resource managers to mitigate harmful ecological and hydrological effects of drought, but drought mitigation is an emerging science and evaluating its effectiveness is difficult. We examined ecohydrological responses of drought mitigation actions aimed at conserving populations...
Pilliod, David; Hausner, Mark B.; Scherer, Rick D. The snag’s the limit: Habitat selection modeling for the western purple martin in a managed forest landscape
The western purple martin (Progne subis arboricola), an avian insectivore, is a species of conservation concern throughout the Pacific Northwest. Compared to the well-studied eastern subspecies (Progne subis subis), little is known of the life history and biology of the western subspecies. Availability of breeding habitat is believed to be a major...
