M-X Environmental Technical Report. Environmental Characteristics of Alternative Designated Deployment Areas, Native Vegetation.
Abstract
In the Nevada/Utah study area the principal vegetation types are arid shrublands with grazing the principal land use. North-south trending valleys are separated by mountain ranges dominated by woodlands, brushlands, and sparse forests. Agriculture is essentially confined to valley bottoms where the principal crop is alfalfa hay used for supplemental livestock feeding. Nevada counties in the study area range from about 0.2 to 2 percent cropland; Utah counties in the study area have slightly more cropland, ranging from about 1 to 4 percent. In the Texas/New Mexico study area, irrigated croplands and heavily grazed rangelands predominate. The natural vegetation consists of short grass prairie. Most Texas countries in the study area are more than 50 percent cropland, whereas the New Mexico countries, except for Curry, have less than 30 percent cropland. Rangelands predominate in New Mexico counties (U.S. Dept. of Commerce, 1974b).
