Title: Impacts of Prescribed Burning on the Survival of Douglas-Fir and Ponderosa Pine in the Boise National Forest

Project Proposal Abstract: The exclusion of fire from forests that historically burned on a periodic basis has affected stand structure and forest health conditions on a landscape scale. Currently, stand replacing wildfires occur on our forests because of the build-up of large fuel loads. The National Fire Plan denotes the use of prescribed fire as a primary tool to reduce fuel loads in our National Forests. Many land managers are uncertain of the effects of prescribed fire on the overall health of the forests because of primary mortality directly attributed to fire and particularly to secondary mortality caused by bark beetles and other attacking insects. Our proposal addresses Task 2 by examining the impact of prescribed fire on tree mortality over a four-year period. We are establishing 1000 individual tree plots, of which 800 will be prescribed burned and 200 untreated as a control for comparison. Coarse woody debris, vegetation, litter, and duff are measured on each plot. Fire intensity and severity will be measured during prescribed burning with thermocouples and related to root mortality, bole char and crown scorch. ANOVA, regression and discriminant analysis will be used to correlate fuel consumed with fire intensity and subsequent tree mortality over a three-year post-burn period. The results will provide needed information to land managers who are asking similar questions throughout the Intermountain Region.
