<br />• RS-CD (3) <br />speed up revegetation of areas depleted by heavy grazing, cultivation, <br />and other disturbances. Combinations of stockwater development, :__..:.:~, <br />and deferred grazing help improve grazing distribution and maintain range <br />condition. The production of vegetation suitable for livestock grazing <br />is limited by low rainfall in summer. Contour furrowing and pitting are <br />practices that improve water infiltration and reduce runoff and are especi- <br />ally effective on rangeland in poor or fair condition. <br />This unit generally is suited to windbreaks and environmental plantings. <br />It is limited mainly by lack of adequate rainfall in summer. Supplemental <br />irrigation may be needed when planting and during the early stages of growth. <br />Cultivation to reduce plant competition usually is necessary, particularly <br />while the plantings are young. Among the trees that are suitable for planting <br />• are Ponderosa pine, Russian olive, Colorado blue spruce, and Eastern red cedar. <br />Amont the shrubs are caragana, lilac, honeysuckle, and sumac. <br />Wildlife, such as cottontail rabbit, squirrels, pheasants, mule deer, <br />and mourning dove utilize this soil. Irrigated crops provide food and shelter <br />for wildlife. Native rangeland provides shelter and nesting areas. Management <br />for wildlife areas should include protection from overgrazing by livestock and <br />protection from unplanned fires. <br />High shrink-swell and low strength are the primary limiting soil features <br />when planning for the construction of homes and other community developments. <br />The foundations of buildings must be designed to compensate for the high slirink- <br />swell and low strength of FalEa soils. Slow permeability and slope must be <br />considered when planning leach fields or sewage lagoons. <br />• <br />
