More than 80 percent is native range, pasture, or scrub oak forest. About 15 percent of the area is cropland.
Most grassland is grazed by beef cattle.
Some rangeland is also grazed by sheep and goats. Valleys, bottom land, and outwash areas of deep soils are farmed to wheat, oats, cotton, and grain sorghum. Hunting leases for deer, quail, and wild turkey are an important source of income in the area. The major concern of management is controlling woody brush that encroaches on the grassland. Only a few large, through-flowing streams have significant flood plains.
