Shaly Foothill #212 49A, 49B <br />d. Vegetation densityl/ is approximately 20-25 percent. <br />4. Annual Production <br />If the range is in excellent condition, the approximate total annual <br />production (air-dry) is: <br />favorable years <br />normal years <br />unfavorable years <br />700 pounds/Ac 794 Kg/Ha <br />450 pounds/Ac SIO Kg/Ha <br />300 pounds/Ac 340 Kg/Ha <br />Of this production IO percent will Likely be unpalatable or out of <br />reach to grazing animals. <br />5. Soil s <br />The, soils on this site are shallow and well drained. They occur on <br />upland ridges, escarpments, and hillsides. The parent material <br />source is residual and the parent rock is calcareous and„ <br />noncalcareous shale. The surface textures vary from clays to silty <br />clay foams and cobbly silt clay Zoams. The surface. layers vary in <br />reaction from a pH of 6.1 to 9.0. <br />• <br />Permeability is slow and the available water capacity is low. The <br />surface runoff is medium to rapid and the hazard of erosion is <br />moderate to severe. <br />Soil Unit Percent -Slope • <br />Lo uviers clay, silty clay loam ~3-25 <br />Louviers cobbly silty clay Loam 5-40 <br />Midway silty clay Loam 5-30 <br />B. MAJOR USES AND INTERPRETATIONS FOR: <br />1. Grazing <br />The site produces fair forage for cattle and horses during years of <br />average precipitation. It provides fair to good forage for sheep, <br />antelope, and .deer. Care should be exercised so that this site is <br />not overgrazed because of the hazard of severe water erosion on <br />steep slopes. - - - <br />1/ Vegetation density = basal area. This is the area of ground surface <br />covered by the perennial stem or stems. Usually, this is measured one <br />inch (2.54 cm) above the soil in contrast to the full spread of <br />perennial foliage. <br />• <br />-4- <br />
