California's trees are at risk from insects and diseases that can move on firewood. In San Diego County alone, tens of thousands of oak trees have been killed due to the Goldspotted Oak Borer, an insect researchers believe was initially brought to California on infested firewood. Other dangerous tree pests, such as the Emerald Ash Borer, have been found on firewood at California's borders.

Best Management Practices
Why is moving firewood such a bad idea? Tree-killing insects and diseases can lurk in firewood. These insects and diseases can't move far on their own, but when people move firewood they can jump hundreds of miles.
