There are three Forest Health Protection (FHP) field offices in Alaska:

  • Anchorage
  • Fairbanks
  • Juneau 

Our mission is to protect and enhance forest health through the transfer of information and resources to our partner landowners and managers. Our staff works to monitor and understand the impacts of damaging outbreaks of insects, diseases, and invasive plants, and offer management guidance and funding to prevent or minimize damage whenever possible 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. FHP 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. The links for each of our field offices provide key information about the most important diseases, insects, and noninfectious disorders affecting forest health in each forested region of the state. The invasive plant page summarizes ongoing work to confront the challenges posed by invasive plants statewide. Learn more about our Aerial Survey program, which allows us to survey approximately 30% of the 127 million acres of forested land throughout the state each year.

2014 Forest Health Conditions in Alaska 

Report cover showing wooly sawfly, float plane, orange hawkweed, a lingren insect trap and more.

The 2014 Forest Health Conditions Report is available! This report reviews our current knowledge of forest health in Alaska. Its purpose is to help resource professionals, land managers, and other decision makers identify and monitor existing and potential forest health risks and hazards. The report is based on data collected in annual aerial detection surveys, ground surveys, permanent plot monitoring efforts, follow-ups to public requests, and input, and early detection work. Emphasis is given to damaging agents observed in 2014. Readers need to be mindful that this is not a complete survey of the 127 million forested acres in Alaska.   The report is organized around the status of four categories of damaging agents: insect pests, diseases, noninfectious disorders, and invasive plants.
