Forest Damage Survey for 2001

This data represents areas of forest damage due to insect infestation, disease, winter damage, fire, flood, landslides, and windthrow. The information was collected, cooperatively by aerial surveys by both the USFS, Forest Health Protection (FHP) and ADNR, Div. of Forestry. Surveys are conducted primarily in July and August so that pest "signatures" may be identified during the optimal period for symptom development of ocular estimation. The aerial survey is coordinated such that the maximum extent of recent bark beetle damage (fading trees) and insect defoliation (discoloration, foliage loss) patterns may be determined. Aerial survey flights are termed as "local" if they can be completed within 1 day from the survey base and "regional' if more than 1 day is required to complete the survey reconnaissance. Surveys are flown in Southeast Alaska, Southcentral Alaska and Interior Alaska.
