Please help protect Oregon's forests by not moving firewood from other states or even long distances within the state. Other states have damaging pests and diseases that are not yet established in Oregon such as emerald ash borer, sirex woodwasp, gypsy moth, Asian longhorned beetle, and oak wilt disease.
Even if you can't see any insects, holes, sawdust, or disease it doesn't mean that the wood doesn't have any invasive species hidden inside. There is a good chance that even the experts wouldn't be able to find organisms such as insect eggs the size of a pin head or microscopic fungus spores in a pile of firewood.
