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.

New Study: Evaluating Effects and Effectiveness of Fuel Breaks
Fuel breaks are intended to reduce fire size and frequency, and can potentially reduce rates of fire spread. To accomplish these objectives, managers construct fuel...
Subalpine Tree Recruitment Affected by Warming, Seed Provenance
To test how warming will alter subalpine tree recruitment, researchers designed an experiment in the Rocky Mountains, Colorado over five years. They sowed seeds from...
Potential Trophic Cascades Triggered by Barred Owl Range Expansion
Barred owls have expanded their range into the Pacific Northwest, greatly impacting the demography and behavior of northern spotted owls. Still, little is known...
Mountain Goat Abundance and Population Trends, Olympic Mountains, 2016
Mountain goats, which were introduced to the Olympic Mountains in Washington in the 1920s, can act aggressively towards visitors and damage native plant communities. In...
Insect Responses to Climate and Weather in Sagebrush Steppe
Most insects are short-lived and have relatively rapid responses to disturbance so are good model organisms for measuring the effects of temperature and precipitation...
specializes in studying and monitoring wildlife, especially raptors, to help understand their ecology, estimate demographic characteristics and population connectivity, and track their long-distance movements. Katzner also uses GPS-GSM telemetry systems and GIS analyses to track birds of prey to understand how renewable energy development can be best managed to reduce risk to birds from turbines and solar fields. Katzner conducts research throughout North America and in central Asia.
Investigating the Interaction between Energy Development and Raptors
involves addressing questions related to habitat use, home range, and population dynamics of birds of prey. We track golden eagles in California to understand how to locate renewable energy development to reduce risk to eagles from turbines and solar fields. Additionally, we are developing high-resolution spatial data of migration corridors of and habitat use by eastern golden eagles in regions of high potential for wind development in the central Appalachian Mountains and in California and Wyoming.
