Blackland Prairies

The Blackland Prairie ecoregion spans approximately 6.1 million hectares from the Red River on the north to near San Antonio in south Texas. It is part of a tallgrass prairie continuum that stretches from Manitoba to the Texas Coast.The Blackland Prairies is named for the deep, fertile black soils that characterize the area. Blackland Prairie soils once supported a tallgrass prairie dominated by tall-growing grasses such as big bluestem, little bluestem, indiangrass, and switchgrass. Because of the fertile soils, much of the original prairie has been plowed to produce food and forage crops.
