Mixed grass prairie
A mixed-grass prairie is an ecotone located between the tallgrass prairies and shortgrass prairies. The mixed-grass prairie is richer in botanical diversity than either the tall- or shortgrass prairie. The mixed-grass prairie occurs in the Central [Great Plains (ecoregion)|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.
