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.

Sagebrush Restoration Handbook – Site-Level Restoration Decisions
The USGS, in collaboration with other federal and university partners, have published part three of a three-part handbook addressing restoration of sagebrush ecosystems...
Spatial Variability of Chinook Salmon Spawning Distribution and Habitat Preferences
A wide range of environmental conditions can affect Pacific salmon’s habitat selection and spawning distribution. Understanding how habitat selection occurs at different...
Climate-Driven Genetic Differences Affect Big Sagebrush Survival
Genetic adaptation of sagebrush seedlings can influence the success of aridland restoration. To explore the survival of genetically distinct big sagebrush seedlings,...
Seventy-Five Years of Land Treatments on Public Rangelands in the Great Basin
The Bureau of Land Management actively manages vegetation on millions of acres of public rangelands in the United States. USGS and BLM compiled over 75 years of records...
Oak Mistletoe Linked to Microhabitat Availability and Avian Diversity
Mistletoes are flowering plants that parasitize woody plants, and can be important food and cover for wildlife. However, the relationship between availability of...
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.
