Distribution of PSHB/FD and KSHB/FD in California

About the Map

This interactive map depicts locations where wood tissue samples have tested positive for P/KSHB specific Fusarium fungus in the lab , or where beetles in traps have been positively identified as P/KSHB.

It is NOT intended to include all trees that may be infested with P/KSHB 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.

Note: This map displays large sets of data. It may take 30 seconds to a couple of minutes to load, depending on your Internet connection.
