Wildfires are common and often large-scale in western conifer forests. In addition, prescribed fires are used in many forest restoration and fuel management projects. Both types of fires can result in tree injury that attract a suite of insect species. Managers require tools to guide salvage efforts and insect population management after fires.
Forest Service scientists examined various aspects of the interaction between fire injury and subsequent insect infestations. Different types of fire injury and tree characteristics, such as the extent of bark damage, crown injury, and tree size, were correlated to infestations by different bark beetles and wood-boring insects. Some of the insects occurred jointly and were associated with both live and dead trees.
