A good description of SOD in California, its hosts, and behavior:
Earlier this month I had the pleasure of visiting the campus at UC Berkeley to attend a training session on Sudden Oak Death (SOD), the disease that has killed many thousands of trees in California and other parts of the world. Losses include many coast live oaks here in Napa County.
To see for yourself, take a short drive up Partrick Road, where the woods are dense. You are likely to spot a number of dead coast live oak trees in this area where SOD was confirmed fairly early in the onset of the epidemic.
The UC Berkeley Forest Pathology and Mycology Lab, which originally identified the disease when it was new to California, continues to refine our understanding of it while it also leads community volunteer efforts to map and mange the disease. The lab sponsors ongoing training for those who are interested in the problem or directly involved in its management.
The March 9 training session, held in the shadow of a large coast live oak by the Tolman Hall portico, was led by lead researcher Matteo Garbelotto, the associate extension specialist and associate adjunct professor who heads the lab research. The lab also sponsors a unique community involvement effort known as “SOD Blitz” days, one of which will be held in Napa on June 4.
Prof. Garbelotto summarized the history of the disease in California from its beginnings to the current state of the research on its biology and management.
