If tYie range is overgrazed, the proportion <br />of preferred forage plants decreases and the proportion of less <br />preferred forage plants increases. Therefore, livestock grazing <br />should be managed so that the desired balance of preferred <br />species is maintained in the plant community. Hange~seeding~:i:s„ <br />suitable if the range is in poor condition, The plants selected <br />for seeding should meet the seasonal requirements of livestock or <br />_wildlife; or both. <br />$I01 If plant cover is disturbed, protection from erosion is <br />needed. Areas that are heavily infested with undesirable plants <br />can be 9moroved by proper p,razin3 management.and--chemical <br />spraying. Slope limits accF~ss by livestock and results in <br />r <br />overgrazing of the less sloping areas. Mechanical treatment is <br />not practical, because the surface is stony and the slopes are <br />steep. <br />$I01 Management practices that are suitable for use on this unit <br />are proper range use, deferred grazing, and rotation grazing. <br />Livestock grazing should be managed to protect the soil from <br />excessive erosion,~Loss of the surface layer results in a severe <br />decrease in pruductivity and in the potential of the soil to <br />produce plants suitable for grazing. <br />$I01 This uni <br />,-a- ,plantings.
