Laurel Wilt

Don't Move Firewood

Protect our National Forests from Invasive Insects and Diseases

Asian Longhorned Beetle, Emerald Ash Borer, and Sirex Woodwasp

When camping on the National Forest, please get your firewood from available sources provided on the forest or a vendor close to your destination. Don't pack your own! Invasive insects and diseases in firewood threaten our native trees and forests. If you move firewood, you could be giving these pests a free ride to new territory.
 

Our forests are severely threatened by non-native insects and diseases that can eliminate entire species of forest trees. Recently introduced insects and diseases such as emerald ash borer, Asian longhorned beetle, Sirex woodwasp, and laurel wilt are wood-infesting species that can and are being transported long distances in firewood. Other non-native pests such as Burning firewoodhemlock woolly adelgid, gypsy moth, thousand-cankers disease, Dutch elm disease, oak wilt, beech bark disease, and sudden oak death may also be moved to new areas in firewood. Once transported into new areas, these pests can become established and kill local trees. We must all do our part to stop the spread of these invasive pests and protect our forests and trees.

How You Can Help...

  • Leave firewood at home - do not transport it to campgrounds or parks.
  • Use firewood from local sources.
  • If you have moved firewood, burn all of it before leaving your campsite.
