A band of dirt bike riders shredded through an open field along historic Mormon Row in Grand Teton National Park that is part of a long-running restoration project to erase thousands of acres of hayfields that once grew there.

The incident Saturday night is believed to have been an organized event involving about 50 people and a drone.

An onlooker who filmed part of the event called the park's dispatch center to report the activity, but by the time rangers could arrive the group was gone. In their wake they left approximately 1,000 feet of track that is two to ten feet in width. 

Park rangers are seeking additional information from anyone who might know the participants. Information can be provided by call or text to the National Park Service Investigative Services Branch Tip Line at 888-653-0009 or email [email protected]. Information can be provided anonymously.   

The historic hay fields along Mormon Row are part of a ten-year project that started in 2014 to remove the non-native grasses and replant the area with 37 species of native plants to restore the site to sagebrush steppe habitat. The investment in the habitat restoration represents several years of effort to collect native seed and treat invasive plants prior to seeding the native species.

This area is important habitat for elk, bison, pronghorn, moose, sage grouse, and a variety of other wildlife, which all depend on sagebrush steppe habitat.  The area that was damaged by the dirt bikes was reseeded in 2019.  This project is a collaborative effort between the National Park Service, Grand Teton National Park Foundation, National Fish and Wildlife Foundation and Teton Conservation District.

Operating a motor vehicle off roadways is a violation and subject to a fine up to $5,000 and/or up to six months imprisonment.  Additionally, the System Unit Resource Protection Act provides that any person or instrumentality that destroys, causes the loss of or injures, of any National Park Service resource is liable for response costs and damages.
