When the goldspotted oak borer was pinpointed as a major contributor to the dense oak tree mortality in San Diego County, there was virtually no information available about this non-native pest or how to mitigate it. Since it’s discovery in 2008, the GSOB Steering Committee member organizations have been rapidly developing information resources to inform land managers, industry professionals and private property owners about GSOB, it’s management and oak woodland restoration.

To help you access the resources best suited to your situation, we have gathered them together by popular categories, called GSOB Resource Toolkits. The print materials are available to download and copy as needed. For larger quantities, hardcopies for several of these materials may be available at no cost.

To inquire about print material availability or if you are unable to find the resource you are seeking on these Toolkit pages, contact Jan Gonzales at
