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 ]
Although most regions of Canada have experienced drought, many of the southern regions of the Canadian Prairies and interior British Columbia are most susceptible. During the past two centuries, at least 40 droughts have occurred in western Canada with multi-year episodes being observed in the 1890s, 1910s, 1930s, 1960s, 1980s, and the early 2000s.
The formation of the Canadian Prairies started with the uplift of the Rocky Mountains near Alberta. The mountains created a rain shadow which resulted in lower precipitation rates downwind. [6] The parent material of most prairie soil was distributed during the last glacial advance that began about 110,000 years ago. The glaciers expanding ...
The theoretical maximum possible ground surface temperature has been estimated to be between 90 and 100 °C (194 and 212 °F) for dry, darkish soils of low thermal ...
Arthur Rothstein's Farmer and Sons Walking in the Face of a Dust Storm, a Resettlement Administration photograph taken in Cimarron County, Oklahoma, in April 1936. The Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s.
The Northern Plains' climate is semi-arid and is prone to drought, annually receiving between 16 and 32 inches (410 and 810 mm) of precipitation, and average annual snowfall ranging between 15 and 30 inches (380 and 760 mm), with the greatest snowfall amounts occurring in the Texas panhandle and areas near the border with New Mexico.
The percent change in precipitation for both areas is dependent upon different emission scenarios; with higher emission levels in the future being conducive to greater extremes. Dramatic increases in average annual temperature are also expected, with average winter temperatures already having risen 7 °F in the past 30 years.
Nonprofit organizations throughout the former tallgrass prairie region began to reserve or restore small remnants of native prairie. For example, the Native Prairies Association of Texas was founded in 1986 to locate, restore, and protect prairies in Texas; the group currently protects about 2,780 acres (11.3 km 2) of Texas prairies.
