Maps
OakMapper: GIS tool that allows the user to learn about P. ramorum distribution in California.
Coming soon – SOD-MAP: SOD-MAP will complement and interface with OakMapper (above) but will fill a different purpose, and will only include P. ramorum reports confirmed by an official laboratory, including negative findings, with the intention of sharing known distribution information gathered by public agencies and research groups across the country.
