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.

Advancing Climate Change Vulnerability Assessments and Adaptation Planning
Public land managers are challenged with responding to future conditions imposed by climate change and implementing decisions at a range of spatial scales. To help...
Polygamy Slows Down Population Divergence in Shorebirds
Sexual selection may promote speciation since competition for mates can favor specific individuals more desirable for reproduction, leading to reproductive isolation...
Nitrogen Deposition Effects on Temperate Forest Lichens and Trees
Nitrogen is emitted from agricultural activities and fossil fuel combustion to the atmosphere, where it is a major source of air pollution that impacts both ecosystems...
A Practitioner's Guide to Understanding Stream Temperature Data and Models
Recent technological advances in stream temperature monitoring and modeling have increased the amount of data that are available throughout the Pacific Northwest. These...
Assessing 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...
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.
