Goldspotted Oak Borer (GSOB) infestations have many impacts. Attacks affect the regional oak tree population, contributing to their death. All those who value oak trees, whether it be for cultural, environmental or aesthetic purposes, are impacted by the rise in oak tree mortality.

The Goldspotted Oak Borer (GSOB) Steering Committee is comprised of Federal, State and Local agencies having regulatory responsibility for forest health and protection of natural resources within the County of San Diego.

GSOB infestations have killed at least thousands of oaks in Southern California, damaging habitat for many important species, reducing cultural resources and natural beauty, and depriving California of an iconic landscape feature.
