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.

is a fire ecologist who leads research to understand how fire and other disturbances affect ecosystems across broad spatial and temporal scales. Doug and his staff study the historical role of disturbances in shaping ecosystem structure, diversity and resiliency; how plant communities change over time; and the role of disturbance in ecosystem management and conservation. To accomplish research across broad landscapes, Doug uses a variety of tools, including field sampling techniques, GIS, and landscape simulation modeling.
Studying and Quantifying Disturbance Dynamics in Natural Communities
often reveals complex relationships between climate, vegetation, topography, and land use, as well as with other disturbance agents, such as insects and wind. To better understand these relationships, we are investigating disturbance regimes (especially fire), successional processes, and vegetation patterns across large landscapes and different ecosystems of the Intermountain West. We use this information to project future ecological change and disturbance dynamics under alternative land-use and climate change scenarios, to help guide management and restoration.
