Help control this destructive forest pathogen! Now in its 19th year, this statewide community science project is vital to managing Sudden Oak Death, which is widespread in Sonoma and Mendocino counties. Join SSU students and staff in contributing to this ongoing citizen science project.

Leader

Kerry Wininger, Director of Center for Environmental Inquiry and former Sudden Oak Death Outreach Coordinator for the UC Cooperative Extension of Sonoma County.

Details

On the preserve, we will drive to different spots for a one-mile walk to collect leaves and record basic data in teams of two or three people. We will be walking on a rocky road that has varied terrain to accommodate different levels of fitness. All equipment will be provided and there is no previous experience required.  

Collected samples will be sent to the UC Berkeley Forest Pathology Lab for analysis, and participants  can see 2023 SOD Blitz results online at https://ucanr.edu/county/ucce-sonoma-county/sudden-oak-death-program

This event is free of charge, family-friendly, and no previous experience or knowledge about Sudden Oak Death is required. CEI SOD Blitzes are in partnership with the UC Master Gardener Program of Sonoma County and UC Cooperative Extension, Sonoma County, with funding from the USDA Forest Service.
