• no spaces among them of less than 8 to 10 inches, were counted as <br />one plant but when there was a distinct division of space that broke <br />up the continuity of the shoots around the perimeter of the clump <br />another plant was counted. Average height for each woody species <br />in each plot was also measured. The plot size for determining woody <br />plant density was 10 meters by 10 meters thus enclosing 100 square <br />meters. <br />There was an average of 14 plants per plot for aspen, 17 plants <br />per plot for mountain brush and 11 plants per plot for sagebrush <br />types (Table 4). The plot data for each vegetation type is shown <br />in Table S and the analysis of variance for this data is shown in <br />Table Sa. <br />• Basal Ground Cover <br />The basal ground cover for most plots on all three vegetation <br />types was considered 7~iKi~ (Table 4). This included litter, duff, <br />crowns of plants and ccehion species. This cover is effective in <br />controlling erosion and in the prevention of evaporation or loss of <br />moisture directly from the soil surface. <br />Reference Areas <br />Two clusters including three acres in area were identified as <br />"reference areas" for each of the three vegetation types found in the <br />Rockcastle mine area. Five of these areas are outside the disturbed area <br />delineated on the accompanying map. Each area is marked by steel stakes <br />at each corner. The species composition determined by percent foliage <br />• cover of herbaceous plants for each of the three vegetation types is <br />shown in Tables 6, 7 and 8 for aspen, mountain brush and sagebrush types, <br />respectively. <br />12/87 II.J-11 <br />
