An emerald ash borer sighting in Canada now puts North Dakota trees in danger from the invasive species.
The insect was found in Winnipeg, just 65 miles north of the state's border.
This is the closest confirmed case of emerald ash borer to North Dakota according to the Department of Agriculture.
North Dakota has more than 92 million ash trees.
Moving uncertified firewood out of the areas under quarantine for emerald ash borers is a federal offense.
