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.

conducts research that focuses on amphibian conservation issues, including invasive species, disease, and land-use change. Using comparative surveys, experiments, and decision analytics Mike and his staff investigate factors that affect amphibian abundance and distribution. Mike is the national lead for the USGS Amphibian Research and Monitoring Initiative (ARMI), created in response to worldwide concern about declining amphibian populations.
The Oregon Spotted Frog
once occurred from southwest British Columbia to northeastern California, but habitat loss and alteration, introduced predators, and water quality degradation have led to population declines. Dr. Michael Adams’s laboratory studies occupancy patterns, population demography, and management options to better understand the status of the Oregon spotted frog in Oregon and inform its recovery. Researchers examine relationships between Oregon spotted frog population trends and habitat variables to understand factors contributing to Oregon spotted frog declines. They also construct models that help evaluate management options.
