SODMAP Guide and Instructions
The SODMAP Project is a partnership of scientists and citizens, working together to create the most complete distribution map of a
forest disease ever produced in North America. SODMAP incorporates laboratory confirmed collections of plant and water samples from 2005 to the present.
It includes both SOD-positive, as well as, SOD-negative specimens to better illustrate the range and distribution of the disease.
SODMAP is the result of a collaboration between hundreds of citizen scientists participating each year in the
organized by the U.C. Berkeley Forest Pathology and Mycology Laboratory, other research organizations, and government facilities.
Contributors to the SODMAP include: M. Garbelotto, UC Berkeley; D.M. Rizzo, U.C. Davis; Ross Meetenmeyer;
UNC Charlotte, Ted Swiecki, Phytosphere Research; Don Owen, Cal Fire; Jack Marshall, Cal Fire; Cheryl Blomquist, CDFA; Lisa Bell, UCCE; Yana Valachovic. UCCE.
Based on our current knowledge, only oaks within 1 km (0.6 mi) of known infected trees are at high risk of becoming infected.
Water results are indicative of presence of the SOD pathogen in a water course, but should not be used to determine risk
of infection for neighboring trees. We urge all oak owners to check the SODMAP yearly and to take preventive action to protect
their trees if infections are reported within
1 km of their property. Detailed management recommendations can be learned by attending free
SOD workshops at UC Berkeley or
SOD community meetings
organized in the Fall around the Bay Area.
