Agroecoregions of the northern Great Plains (from Padbury et al., 2002) including the provinces Alberta, Saskatchewan, and Manitoba in the Canadian Prairies; and Montana, Wyoming, North Dakota, South Dakota, Nebraska, and Minnesota of the United States. For a description of the Agroecoregions 1 to 14, see Padbury et al. (2002).

Spring (March, April, May) temperature (left) and precipitation (right) predictions for 2050 by the Canadian (CGCM2) (top) and UK Hadley Centre (HadCM3) (bottom) global climate models. Predicted temperature (°C) and precipitation (%) changes are compared with the baseline period of 1961 to 1990 (obtained from www.pacificclimate.org/tools/select, verified 6 Sept. 2007).

Aridity scenarios for the 2050s based on forecasts of precipitation and temperature from the Canadian (CGCM2) (top left) and UK Hadley Centre (HadCM3) (top right) global climate models. These GCM experiments represent warm-dry and cool-wet scenarios, respectively. Aridity map for the Prairie Provinces (bottom left) for the baseline period 1961–1990 (from Sauchyn et al., 2002, 2003).
