Forest Health
Forest health has been defined by the production of forest conditions which directly satisfy human needs and by resilience, recurrence, persistence, and biophysical processes which lead to sustainable ecological conditions.
The health of national forests and grasslands is paramount to our mission of caring for the land and serving people. The Forest Service works to maintain, enhance, and restore healthy forest conditions on the national forests and grasslands.
