Hunting leases for deer, quail, mourning dove, wild turkey, and javelina are an important source of income. The major concern of management is controlling brush and cactus that invade the native grasslands. Locally, saline and alkali soils are a land use problem. Much of this plain is gently undulating and somewhat dissected by intermittent drainageways. Average annual precipitation -425 to 525 mm.
Maximum precipitation is during the growing season.
Rainfall is adequate for the growth of range grasses. In most years it is inadequate for cropland because of saline soils, high temperatures, and high evaporation and transpiration rates. Locally, deep wells and ponds provide water for livestock, domestic use, and irrigation. Most of the soils are Usterts and Torrerts. They are deep, fine textured saline soils that have montmorillonitic mineralogy.
