The Wood bison is the northern cousin of the Plains bison that roams many states down-below. Wood bison are the largest land animal in the entire Western Hemisphere! A large, mature bull will often weigh 2,250 pounds versus the 1,900 pounds of the smaller Plains. A mature cow will weigh in at about 1,000 pounds. Calves are born in May to July, are a reddish color for a few weeks and weigh in at 40 pounds at birth. They begin to grow horns and develop a bison’s “hump” at about two months. Bison are grazers and feed primarily on grasses, sedges and forbs.
In, 2015, the Alaska Department of Fish and Game released a total of 130 wood bison along the Innoko River near the community of Shageluk. The Alaska Wildlife Conservation Center partnered with ADF&G and assisted with the holding, quarantine and breeding facility for the wood bison to be released.
