BUFFALO, Wyo. (AP) — Bighorn National Forest officials are investigating damage to more than 100 trees in the Powder River Ranger District.
Forest Service employees on a routine snowmobile patrol recently noticed directional arrows carved into trees.
District ranger Mark Booth says it is a federal offense to cut or damage trees in national forests without permission.
He says violators can be fined $100 for the first tree and $50 for each additional tree.
Foresters say cutting into a tree makes it more susceptible to disease and rot, shortening the tree's life.
