<br />28 <br />copper levels in herbaceous vegetation were usually higher than those found in <br />lodgepole pine. <br />Cyanide (CN) concentrations in herbaceous vegetation and lodgepole pine <br />in 1979 were similar (Table 7). In addition, only minor variations i.n <br />concentrations occurred among sartples from the six locations. fly :mall <br />differences were also detected in fluoride (F) levels of both herbaceous <br />vegetation and lodgepole pine samples across the six locations in 1976 and <br />1979. Fluoride levels were significantly lower in 1985 sales, which might <br />be related to a change in laboratories between 1979 and 1985. The average <br />concentration of fluoride in herbaceous vegetation in 1979 was significantly <br />higher than that in lodgepole pine. These differences were not significant, <br />however, in 1985. <br />Correlation of Soil Parameters with Chemical <br />Constituents in Veaetaticn <br />Sirtple linear correlations between some soil parameters and chemical <br />constituent concentrations in herbaceous vegetation and lodgepole pine were <br />made. In general, mast correlation coefficients derived from these analyses <br />were low (Table 8). Correlation coefficients for copper and molybdenum levels <br />in vegetation with copper and molybdenum leve]s in soil were usually :low. <br />Sane correlation coefficients were positive for herbaceous vegtetatia~, but <br />they were negative for lodgepole pine. Therefore, the correlations were of <br />little utility and certainly no predictive equations are warranted. <br />Both soils and vegetation have had sage chemical constituents change <br />between 1976 and 1985. However, much of the change can be attributed to <br />
