Abstract
Dendroctonus beetles (Coleoptera : Scolytidae) are a major mortality agent in old growth pine, spruce-fir, and Douglas-fir forests of the Rocky Mountains. The frequency of recurring bark beetle epidemics depends on the size of the area being considered, how extensively the stand(s) was decimated by a previous epidemic(s), and how fast the stand(s) grows into the hazardous condition. Predictions of when epidemics will occur, their impact, and their duration are tenuous. Partial cutting may perpetuate old growth.
