Potential Effects of Winter Navigation on Movements of Large Land Mammals in Eastern Lake Superior and Saint Mary's River Area. Great Lakes-Saint Lawrence Seaway Navigation Season Extension Program
Abstract
This is a report on field investigations conducted during the winter of 1979-80. The investigations were to determine: the species and relative numbers of mammals that use the ice of St. Marys River and Whitefish Bay for travel; the locations most commonly used for travel; the purpose of using the ice, i.e., migrating, or foraging; whether animals would swim across open water in winter; and to assess potential effects of winter shipping on the movement of mammals on ice. A preliminary assessment of the impact of winter shipping on mammal movements was completed. It considered effects on deer, seasonal migrations, daily movements and direct mortality; the dispersal of wolves, bobcats, lynx, moose, coyotes and red foxes.
