Sudden Oak Death (SOD) is a serious exotic disease that is threatening the survival of tanoak and several oak species in California, including coast live oak. Currently SOD is found in 16 coastal counties, from San Luis Obispo to Humboldt counties. SOD spreads from infected California bay laurel leaves to oaks during wet weather. Management options are available but they are only effective if implemented before oaks and tanoaks are infected, so timely detection of the disease on bay laurel is essential! This is where volunteers like you can help can help out and sample suspected bay laurel leaves at this year’s SOD Blitz in SLO County. The purpose of the SOD Blitz is to inform and educate the community about the disease and its effects, get locals involved in detecting the disease, and produce detailed local maps of disease distribution. The maps can then be used to identify those areas where the infestation may be mild enough to justify proactive management.

The SOD Blitz begins with a training session/presentation where information on the disease and its symptoms on both oaks and California bays are presented, as well as how to collect and record samples of bay leaves. Volunteers then collect suspected bay leaves as well as information about trees and locations over the week-end. Collecting is done individually or in groups, and you can collect as many or few samples as you have time available before dropping off samples at the collection locations by noon Monday. All collecting materials will be handed out at the trainings. Suggested survey and collection locations will also be posted at the trainings, although you are welcome to identify your own property or area of interest. The collected samples are placed in bins at designated collections spots by Monday before noon so they can be sent to the Berkeley Lab for processing.

This year, we will expect to have at least 2 free training sessions, one in North County and one in San Luis Obispo, and all materials needed for collecting will be provided.
