Bison are the largest indigenous land mammals in North America, and there may have been 50 to 60 million of them when Christopher Columbus first arrived. Though 80 percent of Canada's native prairies have been lost, Grasslands National Park represents the most intact example of what remains. It is home to a herd of nearly 200 bison that roam freely.
