Forest and Rangeland Ecosystem Science Center (FRESC)
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.
Pollinating insects are in serious decline across the United States, which not only impacts agricultural plants, but native plants as well.
Semi-arid shrub steppe occupies a vast geographic range with distinct seasonal patterns in precipitation.
The state-threatened western gray squirrel occurs in the northern Cascade Range, Washington, where long-term fire suppression has increased risk of catastrophic wildfire.
The utility of point count surveys to predict wildlife interactions with wind energy facilities: An example focused on golden eagles
Wind energy development is rapidly expanding in North America, often accompanied by requirements to survey potential facility locations for existing wildlife. Within the USA, golden eagles (Aquila chrysaetos) are among the most high-profile species of birds that are at risk from wind turbines. To minimize golden eagle fatalities in areas...Sur, Maitreyi; Belthoff, James R.; Bjerre, Emily R.; Millsap, Brian A.; Katzner, Todd
The use of lead isotope analysis to identify potential sources of lead toxicosis in a juvenile bald eagle (Haliaeetus leucocephalus) with ventricular foreign bodies
A male juvenile bald eagle (Haliaeetus leucocephalus) was admitted to the Wildlife Center of Virginia with a left humeral fracture a large quantity of anthropogenic debris in the ventriculus, a blood lead level of 0.616 ppm, and clinical signs consistent with chronic lead toxicosis. Because of the poor prognosis for recovery and release, the eagle...Franzen-Klein, Dana; McRuer, David; Slabe, Vincent; Katzner, Todd
Use of created snags by cavity‐nesting birds across 25 years
Snags are important habitat features for many forest‐dwelling species, so reductions in the number of snags can lead to the loss of biodiversity in forest ecosystems. Intentional snag creation is often used in managed forests to mitigate the long‐term declines of naturally created snags, yet information regarding the use of snags by wildlife...Barry, Amy M.; Hagar, Joan; Rivers, James W.
