Do Not Move Oak Firewood Out of Local Areas

Goldspotted oak borer (GSOB) larvae remain in cut oak logs and firewood from GSOB-killed trees or green infested trees and are a continual threat of further infestation. Wood from GSOB infested trees should not be removed from local infested areas.  We emphasize that transporting infested firewood is likely the most significant pathway for introducing GSOB into non-infested areas.

To prevent the spread of GSOB and limit the pest’s damage, it is important to manage oak firewood properly.

For information on the availability of personal use only firewood permits for specified areas of national forest land, contact the Cleveland National Forest's Descanso Ranger District at (619) 445-6235.

Management Practices

Homeowners - See Management Options

Area Parks and Campgrounds:

  • Never remove or transport oak firewood in or out of parks and campgrounds
  • Use only local sources of firewood
  • Burn your supply of firewood before leaving a recreation area.

Adhering to above guidelines can help slow the spread of GSOB and the resulting death of California oak trees.
