Forest and Rangeland Ecosystem Science Center (FRESC)
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.

Invasions by exotic annual grasses, most notably cheatgrass and medusahead, are unambiguous threats to rangelands in the western United States, diminishing livestock productivity and increasing wildfire activity.
Incorporation of concepts from landscape ecology into understanding and managing riverine ecosystems has become widely known as riverscape ecology.
Little is known about how lizards and snakes may respond to changes in habitat from climate, invasive species, fire, roads, and natural resource management.

Effects of experimental removal of Barred Owls on population demography of Northern Spotted Owls in Washington and Oregon—2017 progress report
Populations of Northern Spotted Owls (Strix occidentalis caurina; hereinafter referred to as Spotted Owl) are declining throughout this subspecies’ geographic range. Evidence indicates that competition with invading populations of Barred Owls (S. varia) has contributed significantly to those declines. A pilot study in California showed that...

Rivers are social–ecological systems: Time to integrate human dimensions into riverscape ecology and management
Incorporation of concepts from landscape ecology into understanding and managing riverine ecosystems has become widely known as riverscape ecology. Riverscape ecology emphasizes interactions among processes at different scales and their consequences for valued ecosystem components, such as riverine fishes. Past studies have focused strongly on...

Monitoring stream temperatures—A guide for non-specialists
Executive SummaryWater temperature influences most physical and biological processes in streams, and along with streamflows is a major driver of ecosystem processes. Collecting data to measure water temperature is therefore imperative, and relatively straightforward. Several protocols exist for collecting stream temperature data, but these are...
