Invasive Shot Hole Borer (ISHB) and Goldspotted Oak Borer (GSOB) Workshop

@ City of San Luis Obispo Corporation Yard
on Thursday, May 9, 2019
in San Luis Obispo, CA


CalFIRE is hosting an invasive shot hole borer (ISHB) and goldspotted oak borer (GSOB) workshop in San Luis Obispo on May 9th from 9:30-2:30.  For more information on the training and to register, please click on

These insects have not been found yet in our County but they are very close and we are especially concerned about the ISHB which can attack over 110 tree species. Many of these are native riparian species such as Sycamore, Cottonwood, Alder, Willows, Box Elders and this insect also attacks coast live oak and valley oaks.

Please come and attend this local workshop so you can learn how to identify these invasive insects and report them if you see them in our county. We'll cover these topics in the classroom, then have a hands-on lab to learn how to identify signs of shot hole borer damage, set up a monitoring program, and sample trees. 

$30.00 Registration fee includes lunch, a ISHB Field Guide, and ISHB Demonstration Kit. Pre-registration is required. Click here to register.

CalFIRE has applied for CEU's from the Department of Pesticide Regulation and the International Society for Arboriculture.
