Report Goldspotted Oak Borer Symptoms

Under a collaborative program, agencies and organizations are working together to determine the distribution, impact and possible prevention methods of tree mortality caused by Goldspotted Oak Borer (GSOB). Research includes understanding the lifecycle of GSOB, local infestation levels, tree health and susceptibility and the current distribution of oaks affected in San Diego. 

Local citizen awareness can help determine the locations of infestations in the county. If you suspect a GSOB infestation in local oak trees, please answer as many of the questions below as possible.

Providing photos of the trees showing reported symptoms are helpful. You may upload your photos as indicated at the bottom of this questionnaire.

Contact information is important should additional information or an inspection be needed. You may be assured, your information will be kept private.
