The U.S. Forest Service is reminding people of some simple rules this holiday season when it comes to cutting down their own Christmas tree.

Tree cutting permits cost only $5 with a limit of three Christmas trees per person.

Forest Service officials told the Associated Press that "trees can't be cut down in campgrounds, at trailheads, in designated wilderness areas, developed recreation sites, posted timber sale spots, recently planted areas and administrative sites or within 50 feet of any lake, stream or wetland."

Trees also can't be taller than 15 feet and should be cut as close to the ground as possible.

Permits are available at Forest Service district offices and some retailers. The U.S. Northern Regional Forest Service Office is located at 200 E. Broadway Street in Missoula.
