Abstract

Bark beetle populations are at outbreak conditions in many parts of the western United States and causing extensive tree mortality. Bark beetles interact with other disturbance agents in forest ecosystems, one of the primary being fires. In order to implement appropriate post-fire management of fire-damaged ecosystems, we need a better understanding of relationships between bark beetles and wildfire. Interactions can be one of two primary types: Fires can influence bark beetle populations directly by providing significant amounts of susceptible trees which may precipitate serious outbreaks; and effects of bark beetle outbreaks may influence likelihood and behavior of future fires. We examine various aspects of these interactions.
