The western balsam bark beetle is a primary disturbance agent causing mortality to subalpine fir across the Rocky Mountains. Little is known about the biology of this species. Since 2000 we have been sampling downed trees attacked by the insect in a high elevation site in central Colorado. The insect has a two year life cycle. Results will be presented.
