The annual forest health conditions report provided by Forest Service R10, Alaska Region is available online (see link to pdf below). The conditions report contains, but is not limited to, information pertaining to forest insects in the state.
“The primary goal of this report is to summarize monitoring data collected annually by our Forest Health Protection team. The report helps to fulfill a congressional mandate (The Cooperative Forestry Assistance Act of 1978, as amended) that requires survey, monitoring, and annual reporting of the health of the forests. This report also provides information used in the annual Forest Insect and Disease Conditions in the United States report.”
