Desert Shrubland

Between the deserts and the forests are vast expanses of basins, plateaux, and grasslands with a plant cover of grasses, broadleaved herbs, shrubs, and open, arid woodlands. The semi-arid grassland, the open woods, and the desert shrubland constitute the domain of the huge western livestock industry in the 17 states lying roughly west of the 100th meridian. These are known as the range states and they are likely to remain predominantly range states because of the low precipitation, rough topography, and shallow, rocky and saline soils.

Rangelands of the western United States are becoming an increasingly important resource for many uses, including livestock grazing, wild-life habitat, recreation areas and watersheds. These lands have much undeveloped potential and can be greatly improved to better sustain these many demands. Herbaceous weed control-revegetation systems are powerful tools in this improvement.
