ISHB-FD Distribution in California

About the Map

This interactive map depicts locations where wood tissue samples have tested positive for ISHB specific Fusarium fungus in the lab, or where beetles in traps have been positively identified as ISHB. It is NOT intended to include all trees that may be infested with ISHB or associated Fusarium as limited resources do not allow us to confirm all occurrences in areas known to be infested.

Zoom in to see if the pest has been detected in your area, or click here for full screen view. By default, the map shows pest distribution by county and year.
