e 2 <br /> • ibit I <br /> Cover on the natural areas averages about 75% although it appears <br /> much greater. The bunchiness of Crested Wheatgrass gives an illusion <br /> of high cover values while the actual cover values are somewhat <br /> low for this relatively rich soil, especially if compared to totally <br /> natural areas where a cover of 90% on Satanta soils is not unusual. <br /> The cover in the shrubland areas averages about 90% not including <br /> ground areas covered by rock outcrops and boulders. If the rocks are <br /> included, then the cover becomes highly variable depending on the scale <br /> of the area examined. If the entire Stony Steep land area is examined <br /> then cover average about 50%, but ranges from 0% to 100% depending <br /> upon the scale of examination. <br /> On disturbed areas, cover ranges from 0% to about 30%. The amount <br /> of cover is dierectly related to the age of the substrate, that is, <br /> older areas have higher cover than fresh areas. It appears that with <br /> weedy species, a fair protective cover of disturbed areas is acheived <br /> In two or three growing seasons, even on steep slopes. <br />
