We have completed two years of sampling of fire-affected and fire-unaffected stands at the sites of five fires in Montana and Washington. Progress 01/01/04 to 12/30/04 Outputs This project is focusing on what effects fire has on the susceptibility and suitablility of fire-affected Douglas-fir to Douglas-fir beetle. Impacts This project will provide valuable information for managing Douglas-fir beetles after fire. At the end of year three we will be able to determine how fire effects changes in trees that in turn affect beetle and natural enemy populations. Analyses of tree tissues and identification of insects captured in traps for the first two years is complete. Bark beetle and natural enemies populations have been monitored using pheromone traps. Sampling has included tree tissues for assessing changes in tree defenses and nutrient content, and bark samples for assessing brood production of beetles.
