The tallgrass prairie ecosystem covered some 170 million acres (690,000 km 2) of North America. Besides agriculture, much of the shortgrass prairie became grazing land for domestic livestock . Short grasslands occur in semi-arid climates while tall grasslands are in areas of higher rainfall.
The Canadian Prairies (usually referred to as simply the Prairies in Canada) is a region in Western Canada. It includes the Canadian portion of the Great Plains and the Prairie provinces, namely Alberta, Saskatchewan, and Manitoba. [2] These provinces are partially covered by grasslands, plains, and lowlands, mostly in the southern regions.
During the Quaternary period, between 2 and 3 million years ago, the prairies were covered by a glacier, the Laurentide Ice Sheet. Northern hemisphere glaciation during the last ice ages. The accumulation of 3 to 4 kilometres (1.9 to 2.5 mi) thick ice sheets caused a sea level lowering of about 120 metres (390 ft)
However, the region has also suffered a major loss in terms of biodiversity over the course of settlement. Canada as a whole has found itself with under 20% of its mixed grass prairies, under 5% of its fescue prairies, and less than a half-percent of its tall grass prairies. In addition, the prairies have a very high rate of endangered species. [9]
