Oak tree

Join a SOD Blitz and help us gather information on Sudden Oak Death (SOD)!

The annual SOD Blitz events are one of the largest citizen science projects in the country.  The crowd-sourced data has helped refine models predicting the spread of SOD and indicate where preventative treatment may be most useful.  No experience is necessary before the training, just enthusiasm to hike and willingness to learn to identify California bay and tanoak trees.

After attending a one-hour trainingyou will have knowledge and materials to sample symptomatic leaves of bay and tanoak trees, record a few important details, and submit the samples for testing.  Following the training participants will be provided survey packets. Once you have collected the samples they must be returned to the location of your training with 48 hours.

Dates and Location of the Training for District Lands:
