Oregon's Role in SOD Management
Oregon’s Interagency Sudden Oak Death Program works to slow the spread of SOD in the state by surveying for the disease and treating high-risk, infested sites. Eradication treatments are the best approach to help slow the spread of the disease on high-risk sites (sites on the leading edge of the infestation).
In these sites, SOD program contractors cut infected trees (primarily tanoak) and burn plant debris (when it is safe to do so) in a prescribed radius around infected trees, often 300 feet or more. Rapid treatment is necessary to help prevent the disease from spreading across the landscape.

Reporting SOD Locations
Phytophthora ramorum can only be accurately identified by a USDA-certified laboratory using approved culture and molecular techniques. If you see host plants that have the symptoms described on our Resources page and are located outside of known areas of a SOD infestation, take these three steps:
1. Document the location of the diseased plant; obtain latitude and longitude with GPS, smartphone, or a maps program.
2. Take a clear, close-up digital photo of the plant part showing symptoms, a photo of the entire plant, and a photo showing the general setting.
3. Contact the following resources for further instruction.
