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.
Potential reintroduction of the endangered California Condor to parts of its historic range in the Pacific Northwest would benefit from information on possible threats that could challenge recovery efforts. Exposure to environmental contaminants is a key limiting factor for condor recovery in its southern range.
Mercury is a widespread pollutant that poses health risks to humans and wildlife at a global scale. Addressing these risks requires science-based integrated policy approaches.
Understanding the Ecological Importance of Biocrusts and Grazing Prescriptions that Minimize their Disturbance
Biocrusts develop on the surface of soils, comprised of a community of cyanobacteria, mosses, and lichens, and they are commonly found across natural areas in the arid and semi-arid Western U.S.
Mercury and lead exposure in avian scavengers from the Pacific Northwest suggest risks to California condors: Implications for reintroduction and recovery
Mercury (Hg) and lead (Pb) are widespread contaminants that pose risks to avian scavengers. In fact, Pb exposure is the primary factor limiting population recovery in the endangered California condor (Gymnogyps californianus) and Hg can impair avian reproduction at environmentally relevant exposures. The Pacific Northwest region of the...Herring, Garth; Eagles-Smith, Collin A.; Varland, Daniel E.
Herbicides and herbivory interact to drive plant community and crop‐tree establishment
Land management practices often directly alter vegetation structure and composition, but the degree to which ecological processes such as herbivory interact with management to influence biodiversity is less well understood. We hypothesized that large herbivores compound the effects of intensive forest management on early seral plant communities...Stokely, Thomas D.; Verschuyl, Jake; Hagar, Joan; Betts, Matthew G.
Prepublication communication of research results
Publishing of scientific findings is central to the scientific process, and it is traditional to consider findings “provisional” until accepted by a peer-reviewed journal. Until publication, communication of provisional findings beyond participants in the study is typically limited. This practice helps assure scientific integrity. However, a...Adams, Michael J.; Harris, Reid N.; Campbell Grant, Evan H.; Gray, Matthew J.; Hopkins, M.
