MEDORA, N.D. (AP) — The Theodore Roosevelt National Park has implemented firewood restrictions at campgrounds in the North and South Units in an effort to curb the spread of the emerald ash borer.
Officials say only firewood that derived from trees that originally stood within North Dakota will be allowed to be brought into or transported through the park.
The restrictions apply to all firewood regardless of the species.
The park considers firewood to be any wood cut, sold or intended for use as firewood, including chips, limbs, and branches with or without bark.
Superintendent Valerie Naylor says emerald ash borers are a huge threat to the scenery and wildlife habitat at the park.
The insect has killed more than 50 million trees since 2002 when it was first detected in Michigan.
