An Investigative Report on Motorized Vehicle Use within the Gallatin National Forest

Motorized Vehicle in the Gallatin National ForestThe Sierra Club and the Native Forest Network have collaborated on an investigative report that shows how off-road vehicles have permeated nearly every section of Montana’s Gallatin National Forest. The report represents a first-ever look at the impact of motorized vehicles on a single national forest.

During the summer and fall of 2001, the study team spent hundreds of hours and covered hundreds of miles searching for evidence of wheeled motorized trespass in closed areas and in allegedly secure grizzly bear habitat. They also documented with digital cameras and GPS units any trail damage, vegetation damage, vandalism, littering or other impacts they found associated with motorized travel.

Over the last decade the number of state registered off road vehicles in Montana has nearly doubled to 18,953. According to U.S. Forest Service reports, ORV use in the United States increased by more than 150 percent between 1990 and 1998.
