New rules designed to keep invasive pests and diseases out of Oregon forests go into effect Tuesday.
The rules were crafted by the state Department of Agriculture. And they require firewood brought in from outside the Pacific Northwest to be heat treated before it can be sold here in Oregon. Wood cut inside of the state is exempt. So is wood from Washington and Idaho.
Dan Hilburn, director of plant programs at the Oregon Department of Agriculture, says the new rules focus on firewood commonly found in convenience stores and larger retail shops.
"Those kind of bundles come from all over the place," Hilburn said. "If you read the labels they're shipped long distances from central distribution points. And we're trying to encourage people to use the local firewood."
He says firewood can harbor pests such as the emerald ash borer and the Asian longhorned beetle.
