WRIGHTWOOD (AP) — An invasive beetle that kills oak trees has been found in another part of Southern California. State and federal authorities say Tuesday the goldspotted oak borer was detected in recently killed California black oaks in the western San Bernardino County community of Wrightwood. Experts believe the infestation likely resulted from infested oak firewood being brought into Wrightwood. It's the third infestation in San Bernardino County since the bug showed up in the Oak Glen area in 2018 and in the Sugarloaf area of Big Bear last summer. The goldspotted oak borer is native to southeastern Arizona. The U.S. Forest Service says it is a major threat to oaks in California, where it was first detected in San Diego County in 2004 and has killed thousands of trees.
