In June 2004, the National Park Service commissioned Dr. Cormack Gates of the Faculty of Environmental Design at the University of Calgary to conduct an independent assessment on the effects of groomed roads on bison movement during the winter in Yellowstone National Park. Entitled, "The Ecology of Bison Movements and Distribution in and beyond Yellowstone National Park," the report has been completed and is now available to the public.
