South Dakota’s Game, Fish and Parks Department is reminding campers to follow quarantine restrictions on firewood to stem the spread of an invasive insect.
The Yankton Daily Press & Dakotan reports that emerald ash borers were confirmed for the first time in South Dakota in Sioux Falls last May.
The department says the destructive insect has killed millions of ash trees in more than 30 states.
South Dakota has banned wood from outside the state.
Officials have instructed that wood products from Minnehaha County and parts of Lincoln and Turner counties be kept in those areas, unless they’ve been deemed safe to move.
The state has also banned outside wood from entering the quarantine area.
The restrictions will remain in place year round since the insects can survive the winter.
