lungrazedl compares so closely with the Wadge Pasture in cover and producrion belies the • <br />likelihood that grazing effects have been so dramatic as earlier supposed. <br />Climatic Conditions <br />Precipitation data by month from the Seneca II Mine for 1987, 1988, and 1989, as well as the <br />long-term average from the nearby (but lower elevation) town of Hayden, are shown in Figure <br />6. As can be seen, precipitation during Apri! and June 1990 greatly axceede~i that in 1989 <br />during those two months and was about the same in May. In 1989, the April and June <br />precipitation totals were well below the long term average at Hayden, which is, on the <br />average, drier than the Seneca II Mine site due to lower elevation. <br />That 1990 was again a drought year is clearly shown in the assessment of total precipitation <br />for the previous 12 months for 1987, 1988, 1989, and 1990 (Figure 7). Thr~re it can be seen <br />that 12 month cumulative totals were well below those of the previous three drought years <br />until June. Similar treatment of total precipitation for the previous four months (Figure 81 and <br />six months (Figure 9-, reveal that a wet spring during 1990 caused the 4 month and 6 month <br />cumulative values to suggest that, though dry, 1990 was not as droughty as 1989, a fact that <br />seems clearly to be shown in the recovery of cover and production in many of the reclaimed • <br />and reference areas. Although precipitation was less extremely low than in 1989, heat during J <br />January through June, expressed as total degree-days at Hayden (Figure 101 was about 7.9 <br />percent above long-term average. This no doubt dampened the effectis of the favorable spring <br />1990 precipitation. <br />Sample Adeauacv <br />A summary of sample adequacy calculations for the parameters of cover, production and <br />woody plant stem density are presented in Table 41 (Appendix 1). As can be seen in Table <br />32, sample adequacy was achieved for most cover sampling, was close for production <br />sampling, and was achieved for stem density in the reference areas; high variability in shrub <br />presence in the reclaimed areas left calculated sample adequacy levels astronomical. <br />.~ <br />20 <br />
