Sudden Oak Death Data Layers

Current SOD confirmations (official):

  • Symbol: 
  • Source: Sudden Oak Death Project, COMTF, UC Berkeley.
  • Description: all official confirmed isolations of Phytophthora ramorum (as of publication date), from the California Department of Food Agriculture (CDFA), University of California - Davis, and University of California - Berkeley.
  • Link to SOD confirmation metadata.
    • Links to Images:
  • Symbol: 
  • Source: Sudden Oak Death Project, COMTF, UC Berkeley.
  • Description: tool to view images and pictures of Sudden Oak Death around California.
  • Instructions: make this layer visible by checking the box in the table of contents and refreshing the map.  Then use the "Hyperlink to Images" tool (in the 'OTHER TOOLS' toolbar) to click on the orange lightening bolts to hyperlink to pictures taken at those locations.  For more information, see the OakMapper Help Page.
    • Symptomatic Trees Submitted Via OakMapper:
    • Symbol: 
    • Source: Sudden Oak Death Project, COMTF, UC Berkeley.
    • Description: reports of SOD symptoms as reported by public users through the OakMapper Tree Submittal to track potential SOD coverage across California.  NOTE: these are NOT official confirmations; they only represent possible symptoms and POTENTIAL coverage of SOD.
    • Link to Symptomatic Trees Submitted Via OakMapper metadata.
    • To submit symptomatic tree, go to OakMapper Tree Submittal.
    1/4 mile buffer around SOD confirmations: Areas suspected of having SOD:
    • Symbol: 
    • Source: Sudden Oak Death Project, COMTF, UC Berkeley.
    • Description: areas of concentrated confirmed SOD, last updated on January 16, 2002 (NOTE: some features may be out of date.)
    • Link to Areas suspected of having SOD metadata.
    Areas of tree mortality from aerial survey, 2001:
    • Symbol: 

      •  

    • Source: Sudden Oak Death Project, COMTF.
    • Description: areas of tree mortality, as delimited from aerial flight survey in summer 2001.  Ground truth sampling verified existence of Phytophthora ramorum (Sudden Oak Death), and polygons were color-coded as shown above.
    • Link to Areas of tree mortality from aerial survey 2001 metadata.

    Areas of tree mortality from aerial survey, 2002:

    • Symbol:
