t _ Q <br />s- <br />x <br />The (traditional) null hypothesis being tested was that the bond release block mean (i) was <br />statistically indistinguishable from 90% of the standard, stated as H ? Q. If the absolute value <br />of t was less than or equal to the one - tailed t table value for alpha error probability of 0.10, at (n- <br />1) degrees of freedom, then H was not rejected, and revegetation was deemed successful. <br />Climatic Data <br />Where: x = Bond Release Block Sample Mean <br />Q = 90% of Standard <br />S_ = Standard error of mean [ s <br />S = Sample standard deviation <br />n = Sample size <br />t, = Calculated t value <br />t = Tablet value (alpha = 0.1) see Rohlf and Sokal 1969 <br />SCC has historically provided precipitation data for the Seneca II and IIW Mines. As in previous <br />years, precipitation data from the Seneca IIW mine were used in 2010. Since the long -term <br />average for the mine exists for only 25 years, the long -term average monthly precipitation data <br />from the NOAA administered Western Regional Climate Center (WRCC) for the nearby town of <br />Hayden (Station 053867) were used as an appropriate base for comparison. SCC also provided <br />temperature data for the nearby Seneca IIW Mine in 2010; however, for temperature analysis on <br />the Seneca II Mine, temperature data from the Hayden station have been used since 2005 and <br />were again used in 2010. <br />RESULTS <br />Numerical data are found in Tables 1 through 7 of Appendix 1. Sample data from the 2010 <br />revegetation monitoring studies at the Sage Creek Mine are presented in Tables 1 through 3. <br />Sampling data are summarized in Table 4. Data on species density by lifeform are tabulated for <br />sampled areas in Table 5. Data on relative cover by lifeform are compiled in Table 6. Statistical <br />adequacy of sampling is reviewed in Table 7. The list of plant species observed during these <br />studies (reclaimed and reference areas) is included as Table 8 in Appendix 2. Seed mixes used <br />in the reclamation areas are included for reference in Appendix 3. Photographs of representative <br />7 <br />
