The possibilities of pine beetle control through tree selection are being established. This method involves the removal of high risk trees from the stand. But what are high-risk trees and how may they be recognized? Several investigators, especially Dunning, Keen, and Salman and Bongberg, have developed tree classification systems, primarily silvicultural in character and operation, but with emphasis on the entomological phases of silvicultural problems. The authors describe the various tree classifications that have been proposed and their application to bark beetle control.
