Aerial surveys are completed annually on all Oregon forests.
 
 
"Our mission is to maintain and improve the health of Oregon's non-federal forests."
 
The Department's forest health professionals conduct surveys, evaluations, and 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.
 
Family forestland owners requiring additional information or technical assistance can contact their local ODF stewardship forester.
