Forest & Grassland Health

The Forest Health staff of the Southwestern Region provides assistance and expertise to Federal, State, and Tribal land managers in Arizona and New Mexico concerning forest health conditions and issues. We provide advice and support for projects to help prevent or suppress insect and disease outbreaks. Annually, we conduct survey flights to monitor forest health conditions and provide land managers with information on current issues, with an emphasis on detecting insect activity. Information on current activity and our program is provided through the links below.
