The name Rita Blanca (Little White River) was applied to a stream by Spanish sheepherders in the 19th century. It was later used by the XIT ranch and has been applied to other geographic features in the vicinity.[3]
History
Both Rita Blanca National Grassland and Kiowa National Grassland (KNG), farther west in New Mexico, are the result of the Dust Bowl of the 1930s. The Dust Bowl experience had shown the U.S. Government that climatic challenges made total conversion of the Great Plains to agriculture not only infeasible but undesirable. The National Industrial Act and Emergency Relief Appropriations Act, which passed Congress in 1933 and 1935, gave the federal government authority to buy failed cropland, and the Bankhead–Jones Farm Tenant Act of 1937 gave authority to transfer about 3,850,000 acres (15,600 km2) to the Soil Conservation Service to restore the eroded soil and to protect the grasslands. In 1960, Congress approved the creation of KNG and RBNG.[4]
General description
The elevation of Rita Blanca National Grassland ranges from a high of 4,700 feet (1,400 m) in northwestern Cimarron County, Oklahoma, to a low of 3,700 feet (1,100 m) in southeastern Dallam County, Texas.[4] It is not a solid block of protected land, but rather several small blocks of U.S. Forest Service–owned native prairie grasslands, interspersed with privately owned property. The area is classed as semi-arid, and serves as habitat for pronghorn, rabbits, prairie dogs, coyotes and predatory birds.. Vegetation is primarily shortgrass. It has a land area of 92,989 acres (376.31 km2).[2] The greater part, 77,463 acres (313.48 km2) is in Texas, and the balance 15,860 acres (64.2 km2) is in Oklahoma.[5]
A team led by Donald L. Hazlett studied the history and ecology of the Kiowa and Rita Blanca Natural Grasslands, and reported its findings to the U.S. Department of Agriculture, Forest Service in 2009. The RBNG has a very complex natural ecosystem, with a wide variety of flora and fauna. They found, for example, 826 different species of vascular plants, representing 81 different families.
