Training for the event protocols and on new safety measures due to COVID-19 will take place online in advance of the event, covering Sudden Oak Death, symptoms found on Tanoak and California Bay Laurel leaves, and collection protocols. A Zoom Q&A session will be held on the event date, where you can get clarification about what you've learned, hear what volunteers found on the Preserve over the last three SOD blitzes, and learn how to help more.

You will mail in your leaf samples (in pre-addressed, postage paid envelopes that will be provided) to the lab at UC Berkeley to be tested for SOD, free of charge. Results of the testing will be available in the fall and presented at a community meeting to which all blitz participants will be invited.

This project is part of a statewide survey to help scientists understand the prevalence and spread of this dangerous pathogen. All of the samples brought in will be tested and results collated and entered in a database that will form the basis for further action to be taken throughout the state. Help us save our oak trees.

No previous experience or knowledge is required. This event is recommended for adults, or ages 10 and up with adult guidance.

Details about the online training, how to receive packets, and Zoom Q&A session will be sent to you after registration. If you have not used Zoom before, please allow time to download and install the application before the event. Please log-in a few minutes early, as it may take more than one attempt if servers are busy.
