REEDSPORT, Ore. (AP) — Conservation groups are suing the U.S. Forest Service over plans to build a new trail for off-road vehicles on the Oregon Dunes National Recreation area.

The lawsuit was filed Monday in U.S. District Court in Eugene.

Josh Laughlin of Cascadia Wildlands says the road would go right through a sensitive area currently closed to vehicles under the recreation area’s management plan.

Laughlin says the Forest Service is already unable to control illegal riding that damages fragile plant communities, and building this trail will just make matters worse.

The mile-long trail would link Coos County’s Riley Ranch campground north of North Bend with another parcel of county land that is open to ATV riding.

The Forest Service declined comment.
