Waterton Biosphere Region (established 1979) is a UNESCO Biosphere Reserve encompassing Waterton Lakes National Park in the extreme southwest of the Province of Alberta, Canada. The region includes a section of the east slopes of the Rocky Mountains extending from the Continental Divide to the edge of the Canadian Great Plains to the east, including the Municipality of Pincher Creek and Cardston County. The Glacier Biosphere Reserve and National Park in Montana, USA is located to the south of the area.
The region is administered by Waterton Lakes National Park and the Waterton Biosphere Reserve Association.[1]
The steep environmental gradients from the Continental Divide to the prairies have created an unusually rich mosaic of habitats with their associated flora and fauna.
The biosphere region covers native prairie grasslands, aspen grove forests, subalpine forests, alpine tundra and meadows, cliffs, lakes and freshwater wetlands as well as tame pasture and cropland in the prairies.
