How to get involved in the annual sudden oak death survey.

In 2016 we had to have seven stately 100-year-old coastal live oak trees on our property in Inverness cut down due to sudden oak death (SOD). This sad fact fits into the data from SOD Blitz, a project of the Univerity of California at Berkeley forest pathology and mycology laboratory - that SOD has killed hundreds of thousands of coastal live oak and tanoak trees in Marin and other coastal communities in California and Oregon. In fact, in the past year, the largest sampling of affected trees by SOD Blitz volunteers showed that the incidence of SOD statewide is three times higher than it was two years ago. In Marin, the overall infection rate in 2017 was estimated to be just above 21 percent, an increase of 5 percent from 2016.
