Wood Buffalo National Park: landscape and origins
Wood Buffalo is Canada’s largest national park and one of the largest in the world. It was established in 1922 to protect the free-roaming bison herds of the area.
The park mainly protects part of the Northern Boreal Plains, plus parts of the Southern Boreal Plains and the Northwestern Boreal Uplands. The plain is flat and poorly drained, between 210 and 300 metres (689 and 984 ft) high, and lies on Devonian sedimentary rock: gypsum, rock salt, dolomite and limestone.
Because the rock is permeable and soluble, water seeps away instead of running off above ground. This created karst in the gypsum, salt plains, underground streams, sinkholes and saline creeks. In between lie bogs, meandering rivers, shallow lakes and boreal forest of white and black spruce, jack pine, balsam fir and aspen.
Fire belongs to this forest. The park authority describes it as one of the most important ways the boreal forest renews itself: ash brings minerals into the soil, jack pine needs heat to open its cones, and fireweed is often the first plant to grow back.
Archaeological finds show that people have lived in the area for more than 8,000 years. The communities around the park today are mainly Cree, Chipewyan, Métis and non-Indigenous. It is the traditional territory of the Dene, Cree and Métis.
In 1926 the park was extended beyond the Peace River into the delta to protect bison that had been brought in from the south and had crossed the river.
