Establishment of Wood Buffalo National Park

18 December 1922

Wood Buffalo National Park, which straddles northern Alberta and the Northwest Territories in Canada, is the largest national park in the country and one of the largest in the world. It was created to protect the last remaining herds of wood bison, a northern subspecies of the American bison. The park includes boreal forest, salt plains and gypsum karst, and the Peace-Athabasca Delta, one of the largest inland deltas in the world. It also holds the only natural nesting area of the endangered whooping crane. It was inscribed as a UNESCO World Heritage Site in 1983, and concerns about upstream hydroelectric dams and oil sands development have led to international monitoring of its condition.
