Sudden Oak Death (SOD) is a serious exotic disease that is threatening the survival of tanoak and several oak species in California. By collecting leaf samples during community SOD blitzes and submitting your samples to UC Berkeley diagnostic laboratory, you can help create a detailed local map of disease distribution.
SOD-blitzes inform and educate the community about Sudden Oak Death, get locals involved in detecting the disease, and produce detailed local maps can then be used to identify those areas where the infestation may be mild enough to justify proactive management. You can participating in an existing SOD-blitz or create your own.
Good news: SOD-Blitzes are COMPLETELY FREE thanks to funding from the US Forest Service to the UC Berkeley Forest Pathology Lab!
