ABSTRACT RUNOFF and soil loss from three sagebrush range-land sites and three replicated treatments (natural, clipped, and bare) were evaluated using a rainfall simulator. Relationships between vegetation cover and plant biomass, and between plant biomass and normalized soil loss were determined. A roughness value was determined before and after treatments. Runoff was two to three times greater and soil losses about 20 times greater from the bare treatment than from natural or clipped treatments. Results contribute to a national Water Erosion Prediction Project (WEPP).
