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.

Wildlife Occupancy Patterns before Elwha Dam Removal
The downstream transport of sediments and organics and the upstream migration of anadromous fishes are key ecological processes disrupted in dammed rivers. Removal of...
Comparison of Electrofishing Techniques to Detect Larval Lampreys
Pacific lamprey and Western brook lamprey are suspected to be declining in the Pacific Northwest. These two species of lamprey commonly co-occur with well-studied salmon...
Promoting Moss Growth to Increase Desert Resistance to Cheatgrass Invasion
Biological soil crusts include lichens, mosses, fungi, and bacteria and are important in promoting soil stability and regulating water retention in desert ecosystems...
Estimating the Unknown: Improving the Accuracy of Aerial Elk Surveys
When wildlife biologists survey large ungulates from the air, an unknown number of animals typically go unseen. USGS scientists Kurt Jenkins and Paul Griffin...
Juvenile Salmon Use Thermal Diversity to Maximize Growth
Diel vertical migration, or the daily movement of organisms from deeper to shallower water, has been examined extensively in lakes and oceans, but has been understudied...
Evaluating Effectiveness of Barred Owl Removal for Spotted Owl Recovery
Previous work by the USGS, in collaboration with six other federal and state agencies, documented that high densities of newly colonizing barred owls appeared to be...
provides research and technical assistance in support of wildlife conservation and management issues in national parks of the Pacific Northwest. Kurt's work focuses on population monitoring of species of concern, including Roosevelt elk, Pacific fishers, and mountain goats. Kurt also provides research in support of conserving special status species and has been an integral part of research efforts to evaluate how dam removal and reintroduction of salmon affects wildlife in the Elwha Valley, Olympic National Park.
Investigating Mammalian Ecology and Management in Protected Areas
helps to inform wildlife management decisions in national parks and other protected areas that are key components of the wildlife conservation landscape. The goal of wildlife managers is to preserve the ecological integrity and authenticity of natural systems for future generations. Our work, conducted in close cooperation with the National Park Service, universities and Tribal scientists, aims to increase understanding of mammalian ecology in and around national parks in the Pacific Northwest.
