INSECTS AND DISEASE Researchers at the Intermountain Forest and Range Experiment Station have developed timber harvesting prescriptions that will help save lodgepole pine stands from devastation by the mountain pine beetle. Past studies have shown that the use of chemicals and massive timber salvage operations will not alter the course of a mountain pine beetle epidemic or reduce the loss of trees. Recent research indicates that the key to managing this destructive forest pest is preventive action before the outbreak of an epidemic. The mountain pine beetle prefers large trees with thick phloem. When these trees are removed from a stand, the beetle's food supply is reduced and the population cycle, which eventually leads to epidemic outbreaks, is interrupted. The preventive prescriptions show strong promise as a method of warding off beetle infestations. Controlling these infestations will help insure future timber supplies and protect other resource values such as esthetics, forage, and wildlife habitat. 18 STARVE THE BEETLES — SAVE THE TREES.
