Forest Health
Forest Health Protection work ensures the long-term health and sustainability of forests and trees through support to the states and the region’s national forests and other federal lands. With partners, scientists on the Rogue River-Siskiyou National Forest provide forest health monitoring information, promote integrated pest management, and provide technical assistance to prevent, suppress, and control pest outbreaks.
