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.

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...
New Study: Dynamic Food Web Modeling in the Snake River
In 2014, the Shoshone-Bannock Tribe conducted an experiment in the Yankee Fork Salmon River in central Idaho to test ecological effects of different marine derived...
Linking Avian Abundance and Mortality at Southern California Wind Facilities
Wind energy facilities near Palm Springs, California are located in an area that is important for bird migration and breeding. Resource managers must conduct surveys to...
Streamflow Generation in High-elevation Tropical Watersheds
High-elevation tropical mountain ecosystems provide sustained water flow to lower-elevations areas throughout the year, but these streams are rarely gauged and little is...
Experiments to Help Restore Mosses in Arid Lands
Biological soil crusts are beneficial to arid ecosystems and occupy bare ground, deterring establishment of invasive annual grasses. To investigate the restoration...
investigates the effects of natural disturbance and management strategies on biodiversity to provide a scientific basis for management of wildlife and habitat. Main areas of Joan's research include habitat relationships of forest birds and the ecology and distribution of special status species, such as forest mesocarnivores, purple martins, and birds in Oregon oak woodlands. Joan’s work focuses on quantifying and mapping wildlife habitat by integrating wildlife ecology with tools, such as lidar. Joan also explores how management of conifer forests in the Pacific Northwest influences species of concern by altering food webs.
Mapping and Modeling Wildlife Habitat
is critical to investigations of species distribution and habitat relationships, and can greatly facilitate management of forests for multiple resources. Joan’s projects integrate an understanding of wildlife ecology with technological expertise from collaborations with biometricians, statisticians, and GIS specialists to develop habitat models that provide reliable and defendable methods for defining and predicting the distribution of wildlife habitat.
