Climatic Data <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 2008. 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 2008; 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 2008. <br />RESULTS <br />Numerical data are found in Tables 1 through 14 of Appendix 1 and Table 15 of Appendix 2. <br />Sample data from the 2008 revegetation monitoring studies at the Seneca II Mine are presented <br />in Tables 1 through 10. Sampling data are summarized in Table 11. Data on species density by <br />lifeform are tabulated for sampled areas in Table 12. Data on relative cover by lifeform are <br />compiled in Table 13. Statistical adequacy of sampling is reviewed in Table 14. The list of plant <br />species observed during these studies (reclaimed and reference areas) are included in Table 15 <br />of Appendix 2. Seed mixes used in the 2001 and 2006 reclamation areas are included for <br />reference in Appendix 3. Photographs of representative locations within the reclaimed areas <br />sampled in 2008, as well as photographs of Mountain Brush and Sagebrush Reference areas, <br />are included in Appendix 4. Graphs of vegetation and climate data are presented in Figures 1 <br />through 10 of this report. <br />In the cover descriptions below, species listed as "also present" were not "hit" during point- <br />intercept sampling but were present within one meter of either side of the 50 m sample transect <br />line. Unless otherwise stated, all cover values are for absolute vegetation including first hit data <br />only. Percentages are rounded to one tenth of a percent to simplify discussion of the results. <br />2001 Reclaimed Area <br />(Photographs 1-3) <br />COVER <br />(Table 1) <br />0 8
