The listing below is based on material compiled by Peter Scott and furnished by Jack Dubois Curator of Mammals, Manitoba Museum of Man and Nature in Winnipeg. Their habitat is marginal until well upriver. Hunting pressure makes them hard to see. Porcupine are present in low numbers. The arctic hare is the more common of the two.
Wolverines are present but never abundant.
