Title: Effects of Disturbance History, Landscape Pattern, and Weather on Wildfire Severity in Southwestern Oregon: Implications for Management of a Fire-Prone Landscape

Project Proposal Abstract: Many of the lessons from the large fires of 1987 and 2002 in southwestern Oregon remain hidden in unanalyzed data. As Forest Service and BLM managers design and implement responses to these fires, they need information about the relationship of fire severity to multiple factors including management practices, fire history, fuel, topography and weather. The project has three major objectives: 1) Determine how fire severity in stands is influenced by history of management actions and wildfire; 2) Evaluate the relative contribution of vegetation structure, topography, landscape pattern, and weather to variation in the fire severity and 3) Characterize the spatial pattern and spatial correlation of vegetation changes resulting from the fire. We will conduct an analysis of fire severity using pre- and post-fire aerial photography, a managed stand data base, stand exams, FIA plots and other GIS layers. Fire severity will be measured in terms of damage to tree cover. We will use an existing vegetation change analysis conducted with TM imagery to characterize general spatial patterns of fire severity. Logistic regression and spatial statistics will be used to test hypotheses about the relative importance of different factors in explaining the variation in fire severity. Staff from the BLM and Forest Service units will cooperate on the project and the information will be applied in planning models and practices that are designed to reduce risk to firefighters, communities and forest resources from future high intensity fire.
