The shortgrass prairie steppe is the westernmost part of the Great Plains region. The Columbia Plateau in southern British Columbia, Oregon, Idaho, and Washington state, is an example of a steppe region in North America outside of the Great Plains.
Steppe, in physical geography, refers to a biome region characterized by grassland plain without trees apart from those near rivers and lakes. The prairie (especially the shortgrass and mixed prairie ) is an example of a steppe, though it is not usually called such.
The region is located to the east of the Rocky Mountains, much of it covered in prairie, steppe, and grassland. They are the western part of the Interior Plains, which include the mixed grass prairie, the tallgrass prairie between the Great Lakes and Appalachian Plateau, and the Taiga Plains and Boreal Plains ecozones in Northern Canada.
Nonetheless, as many as 300 different plant species may grow on less than three acres of North American tallgrass prairie, which also may support more than 3 million individual insects per acre. The Patagonian Steppe and Grasslands are notable for distinctiveness at the generic and familial levels in various taxa.
Prairie ecosystems in the United States and Canada are divided into the easternmost tallgrass prairie, the westernmost shortgrass prairie, and the central mixed-grass prairie. Tallgrass prairies receive over 30 inches of rainfall per year, whereas shortgrass prairies are much more arid, receiving only 12 inches or so, and mixed-grass prairies ...

The High Plains ecology region is designated by 25 on this map. Childress County, Texas, June 1938.. The High Plains are a subregion of the Great Plains, mainly in the Western United States, but also partly in the Midwest states of Nebraska, Kansas, and South Dakota, generally encompassing the western part of the Great Plains before the region reaches the Rocky Mountains.
Left alone, the valleys are often woodland, with the ridgetops transitioning into tallgrass prairie when not turned into pasture or used for row crops. Coulees provide shelter from wind and concentrated water supplies to plants which would otherwise struggle to survive in the xeric sagebrush steppe .
