The Washington State Department of Natural Resources and USDA Forest Service conduct annual aerial surveys to identify, map, and monitor the impacts of insect and diseases on forest lands throughout the state. Aerial survey data are verified with ground-based observations and are compared against the results of other forest health research happening throughout the state.
Survey results are compiled into an annual report called Washington’s Forest Health Highlights, or, as it more congenially known, “the bugs and crud report.”
Due to the intensive time required to collect and analyze the survey data, then verify and publish the results, the Forest Health Highlights outlines forest health conditions observed in the previous year. Nonetheless, these reports provide critical benchmarks for the presence or absence, scope, and severity of insects, diseases and other environmental conditions that adversely affect the health of trees and forests in Washington state.
