or equal to the one - tailed t table value for alpha error probability of 0.10, at (n -1) degrees of freedom, then <br />H was not rejected, and revegetation was deemed successful. <br />Climatic Data <br />SCC has historically provided precipitation data for the Seneca II and IIW Mines. As in previous years, <br />precipitation data from the Seneca IIW mine were used in 2010. Since the long -term average for the mine <br />exists for only 25 years, the long -term average monthly precipitation data from the NOAA administered <br />Western Regional Climate Center (WRCC) for the nearby town of Hayden (Station 053867) were used as <br />an appropriate base for comparison. SCC also provided temperature data for the nearby Seneca IIW <br />Mine in 2010; however, for temperature analysis on the Seneca II Mine, temperature data from the <br />Hayden station have been used since 2005 and 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 revegetation <br />monitoring studies at the Seneca II Mine are presented in Tables 1 through 3. Sampling data are <br />summarized in Table 4. Data on species density by lifeform are tabulated for sampled areas in Table 5. <br />Data on relative cover by lifeform are compiled in Table 6. Statistical adequacy of sampling is reviewed in <br />Table 7. The list of plant species observed during these studies (reclaimed and reference areas) is <br />included as Table 8 in Appendix 2. Seed mixes used in the reclamation areas are included for reference <br />in Appendix 3. Photographs of representative locations within the reclaimed areas sampled in 2010, as <br />well as photographs of Mountain Brush and Sagebrush /Snowberry Reference areas, are included in <br />Appendix 4. Graphs of vegetation and climate data are presented in Figures 1 through 8 of this report. <br />In the cover descriptions below, species listed as "also present" were not "hit" during point- intercept <br />sampling but were present within one meter of either side of the 50 m sample transect line. Unless <br />otherwise stated, all cover values are for absolute first hit data only. Percentages are rounded to facilitate <br />discussion of the results. <br />7 <br />
