SODMAP Mobile is an app for tracking SOD. This App calculates the risk to your oaks based on real SOD monitoring data. In Sonoma County, these data are created mainly by the public each spring during the SOD BLITZ, an educational, data-collecting weekend led by the Sonoma County SOD program coordinator, Lisa Bell, and the UC Master Gardeners.
