Woodland Potential <br />Ponderosa pine is the principal tree species present on the <br />site. Other species include Douglas-fir which is present on <br />north slopes, bristlecone pine above 9000 feet elevation and <br />pinyon pine on the lower drier slopes. Site index for ponderosa <br />pine is 45, the woodland class is 2D for areas up to 35% slope <br />and 2R for steeper slopes. No site data is available for <br />species other than ponderosa pine. <br />4. <br />5. <br />Native Animal Community Associated with the Potential Plant <br />Community' <br />This range site provided habitats which support a resident animal <br />community that is characterized by mule deer, antelope, small mamals <br />including the black squirrel, cottontail, non-game birds and blue <br />grouse. There is seasonal use by elk. <br />Soils <br />a. Composite description: This site occurs on shallow and well <br />drained soils that have formed on mountain sides and hills in <br />residum of granite, grandiorite, and gneiss. Typically, the <br />surface layer is very gravelly sandy loam with small gravel <br />content by volume of about 40 to SO percent. Stratums are <br />commonly extremely gravelly sandy loam. <br />Permeability is moderate to moderately rapid. Erosion hazard <br />is slight to very high depending on the steepness of slopes. <br />Rooting depth is about 8 to 20 inches, and available water <br />capacity is very low. <br />i <br />
