The scientists from the Forest and Rangeland Ecosystem Science Center capitalize on their diverse
expertise to answer critically important scientific questions shaped by the equally diverse environments
of the western United States. FRESC scientists 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.

Cheatgrass Modifies Microbial Contributions to Nitrogen Cycling in Sagebrush Soils
Cheatgrass invasion not only degrades native sagebrush ecosystems and important rangelands, it can also cause soil microbial communities to change over time. These...
Assessing Health Risks of Anticoagulant Rodenticides Exposure in California Condors
Condors are one of the most endangered bird species globally. The exclusive scavenging behavior of California condors makes them particularly susceptible to exposure and...

Sagebrush Restoration Handbook – Site-Level Restoration Decisions
The USGS, in collaboration with other federal and university partners, have published part three of a three-part handbook addressing restoration of sagebrush ecosystems...
Climate-Driven Genetic Differences Affect Big Sagebrush Survival
Genetic adaptation of sagebrush seedlings can influence the success of aridland restoration. To explore the survival of genetically distinct big sagebrush seedlings,...
works in aridland ecosystems, conducting research on restoration and monitoring of plants and soils of the Intermountain West. Dave and his staff study fire rehabilitation effects and effectiveness, indicators of rangeland health, invasive species ecology, and restoration of shrub steppe ecosystems. Dave works with management agencies to develop tools to help with post-fire rehabilitation monitoring and indicators to assess rangeland health.
Investigating Invasive Species Ecology,
such as that of invasive annual grasses, can help researchers understand the environmental conditions that may lead to their dominance. Invasive annual grasses, such as cheatgrass, are the greatest threat to shrub-grassland ecosystems of the Intermountain West. These grasses can change the natural fire regime, creating more frequent and larger wildfires, among other ecosystem disruptions. The USGS is attempting to identify early warning indicators before conversions from native shrub grasslands shift to annual grasslands.
