Where was the first fur trading in North America?
North American fur trade
By the 1850s the fur trade had expanded across the Great Plains, and the bison robe trade began to decline. The Métis had a role in the depopulation of the bison. Like the Indians, the Métis had a preference for cows, which meant that the bison had trouble maintaining their herds.[102] In addition, flood, drought, early frost, and the environmental impact of settlement posed further threats to the herds. Traders, trappers, and hunters all depended on the bison to sustain their way of life. The Métis tried to maintain their lifestyle through a variety of means. For instance, they often used two wheel carts made from local materials, which meant that they were more mobile than Indians and thus were not dependent on following seasonal hunting patterns.[103]
