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.

USGS and Colville Confederated Tribes Partner for Salmon Recovery
The Okanogan River is a tributary of the Columbia River that originates in British Columbia and flows into northern Washington. Spring Chinook salmon were extirpated in...
Choosy Mothers: Factors that Influence where Salmon Spawn
During their lifetimes, coho and other Pacific salmon are born in freshwater, migrate to sea, and return to their natal streams to breed. Breeding is the final step in...
Post-fire Seeding Success Driven by Moisture and Seed Drills
Wildfires burn approximately one million acres in the Great Basin each year. The BLM implements Emergency Stabilization and Rehabilitation (ESR) seeding treatments...
Lead Poisoning in Birds from Ammunition and Fishing Tackle
Lead is a metabolic poison that can negatively influence biological processes leading to illness and mortality in North American birds. Lead ammunition and fishing...
Sagebrush Bird Community Response to Pinyon-Juniper Removal
Pinyon and juniper woodlands are expanding into sagebrush steppe areas across the intermountain western United States, affecting species that depend on sagebrush. Land...
Floodplain and Confined Valley Forms have Complimentary Roles in Rivers
In montane regions, rivers often alternate between canyon-confined segments and unconfined floodplain segments. Variation in channel confinement influences sediment,...
examines research topics centered on wildlife ecology and conservation biology in natural and human-altered landscapes. David and his staff conduct research and provide technical assistance on demanding conservation issues such as evaluating status, trends, and threats to species of conservation concern, improving methods for implementing and monitoring habitat restoration, and developing novel approaches for monitoring changes in populations, communities, and habitats.
Developing Tools and Techniques for Monitoring Wildlife Habitats, Communities, and Populations
is critically important for documenting trends and learning from the past. We are developing and testing novel approaches to wildlife monitoring, including the use of non-invasive field sampling and molecular markers to determine patterns of species occurrence and population abundance relative to management actions or habitat conditions. We are using remote sensing methods to improve mapping and prediction of wildlife habitats and the quality of those habitats for different species.
