Ecological Effects of Snowmobiles

Abstract

Studies in Ontario showed that snowmobile use caused significant changes in snow structure and wildlife behavior. Snow structural changes by snowmobiles had significant effects on temperature gradients, water holding capacity and melting rate. Snowshoe hare and red fox mobility and distribution also were effected. Snowmobile damage to hardwood saplings and planted pines was significant. Browsing was unaffected except to damaged saplings.
