Forest Health Highlights report

Each year ODF and the USDA Forest Service fly aerial surveys across forested regions in Oregon to map tree damage and mortality attributed to insect, disease, abiotic, etc. stressors. We compile this info in an annual report – “Forest Health Highlights." View previous years on the USFS website.

About the Forest Health Program

The Forest Health Program helps maintain and improve the health of Oregon's private and state-owned forests.

Our forest health professionals conduct aerial and ground surveys to monitor forest insects and tree diseases. They provide technical advice and training in the use of integrated pest management principles to help professional foresters and landowners meet their management goals and objectives.

Stewardship foresters, urban foresters, forest entomologists and pathologists can help landowners identify forest pest problems and develop strategies to manage pests. Contact a stewardship forester or the Forest Health Program for more information.

Saving Oregon Ash video

ODF’s Forest Health team is working with scientists from the USDA Forest Service on a first-of-its-kind effort to save as much of the gene pool of the Oregon ash tree before the arrival of emerald ash borer. The borer is an invasive insect pest that could nearly wipe out this tree as it has done to other ash species in the central and eastern U.S. Seed from throughout the Oregon range of our native ash species is being collected for long-term storage at two USDA Forest Service locations - Dorena Genetic Research Center in Cottage Grove and the National Seed Lab in Fort Collins, Colorado. Watch why this effort is so important to the future of Oregon wetlands and streamside woodlands.
