Forest Health Protection (FHP) Offices/Staff

Our mission is to protect and enhance forest health through the transfer of information and resources to landowners and managers. Our staff works to monitor and understand the impacts of damaging insects, diseases, and invasive plants. FHP provides timely survey and monitoring information, and technical and financial assistance, to Federal, State, and private land managers so they can prevent, suppress, and control outbreaks of forest pests. We also works in partnership with the Alaska Department of Natural Resources and USDA Animal and Plant Health Inspection Service to monitor for newly introduced exotic organisms. An important part of our forest health monitoring program is the aerial survey that we conduct annually in summer to identify and map damage from insects and some diseases. These surveys cover approximately 20 million acres, or 15% of the forested land area in Alaska.
