The mixed-grass prairie is richer in botanical diversity than either the tall- or shortgrass prairie. The mixed-grass prairie occurs in the central plains portion of the Great Plains, varying in width from central Texas in the United States up into southeastern Manitoba, Alberta and Saskatchewan in the northern mixed grasslands of Canada.

The predominant vegetation of the Central Great Plains ecoregion is a rich mixture of prairie Central and Southern mixed grasslands of medium height. The ecoregion is encompassed by the tallgrass and shortgrass prairies — this region has a mix of both tallgrass and shortgrass. Wildflowers occur among the grasses, but very few trees and shrubs do.
The mixed grass prairie was recognized as a mixture of the tallgrass and shortgrass prairies. The dominant grasses found here include grama (Bouteloua gracilis), little bluestem (Schizachyrium scoparium), needle-and-thread grass (Stipa comata), wheatgrass (Agropyron smithii), Carex filifolia, junegrass (Koeleria cristata), and Poa secunda.

The Sandhills, often written Sand Hills, is a region of mixed-grass prairie on grass-stabilized sand dunes in north-central Nebraska, covering just over one quarter of the state. The dunes were designated a National Natural Landmark in 1984. [1]
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 National Grassland consists of about 100 tracts of land interspaced with privately owned ranchland. It is located in the mixed grass prairie region. The terrain is characterized by sandy and red slate hills in addition to grassland and oak brush. The creek bottoms are wooded with cottonwood, elm, and hackberry. Wildlife includes white ...
In short grass prairie there are two dominant plants, buffalo grass (Bouteloua dactyloides), is a strong and hardy grass that is the favorite of grazers. The second is blue grama (Bouteloua gracilis), which is essential for soil retention. [7] In tallgrass prairie there are four dominant species, big bluestem grass (Andropogen gerardii), Indian ...
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.
