Landscape Dynamics and Disturbance

Forest and stream ecosystems undergo progressive, slow change by processes such as succession and soil development. Abrupt changes are induced by disturbances such as fire, flood, wind, landslides, forest cutting, roads, insects, and volcanic activity. The interplay of disturbances and succession drive ecosystem dynamics. We study the past and present frequency, severity, duration, and spatial pattern of natural and management disturbance processes that dominate the disturbance regimes of the Andrews Forest and other parts of the Pacific Northwest. We also study effects of disturbances on biota and on ecological and watershed processes.
