TextPublication details: Manitoba : 1984Online resources: Abstract: The pothole region of North America, lying primarily in the Aspen Parkland Biome, is characterized by distinctive knob and kettle topography formed as a result of Pleistocene glaciation (Kiel et al 1972). Nearly 10 million water holding depressions of a variety of types are present in this area (Jahn 1969), occupying nearly 42 million hectares. Productivity of these small wetlands for waterfowl is very high. Their shallow water, rapid spring warming and fertile soil provide an abundance of plant and animal foods, and this area supports about 62%of North America's waterfowl populaton (Bellrose 1980). Muskrats and other aquatic animals also thrive in these wetlands.
