Abstract: Ranking or assigning priorities to problems is an essential step in research problem selection. Up to now, no rigorous basis for ranking forest insects has been available. We evaluate and rank forest insects with a systematic numerical scheme that considers insect impact on the multiple-use values of timber, wildlife, recreation, and water. The result is a better perspective on insects as important elements of forest ecosystems.
