The U.S. Forest Service proposes reversing its “closed unless designated open” rule: national forest trails would be open to ATVs, dirt bikes and 4x4s unless marked closed. Supporters say this would expand access; opponents warn of habitat damage and user conflicts.
The Department of Agriculture, which oversees the Forest Service, says the change would broaden recreation access and simplify regulatory requirements. Most national forests use travel-management plans that designate which roads and trails are open to hikers, horseback riders, mountain bikers or motorized recreation. Public comments on the proposal ran through Sept. 23.
Chris Edgington of Montana Trout Unlimited said crossings on a six-mile stretch of Montana’s Middle Fork of the Judith River caused sediment runoff that buried fish and aquatic-insect habitat. Before 2023, the area had more than 80 entrances and 27 shallow crossings; he said the fish population was estimated at less than 10% of what a river of its size and character would be expected to support. A coalition rebuilt 1,000 feet of riverbank, reduced crossings by 80% and added a trail segment. Supporters say expanded access could help elderly visitors and people with disabilities reach public lands.
