sought, revegetation will be considered successful for cover when mean cover for a bond release <br />block is at least 90% of the calculated success standard or approved technical standard. <br />WOODY PLANT DENSITY: For purposes of comparisons in this document, woody plant density <br />at the Seneca II-W Mine is evaluated using a technical standard of 1,000 shrubs per acre. <br />Climatic Data <br />Precipitation data were collected at the Seneca II-W Mine during the period 1990 through 2003. <br />For years 1982 through 1989, SCC provided precipitation data from the nearby Seneca II Mine. <br />Since the data record for Seneca II exists for only 21 years, the long term average monthly <br />precipitation data from the Western Regional Climate Center (WRCC) for the nearby town of <br />Hayden was used as an appropriate base for comparison. Information on degree-days was <br />based on temperature data from the Seneca met station 2 at the Seneca IIW Mine. <br />RESULTS <br />Numerical data are found in Tables 1 through 16 of Appendix 1. Sample data from the 2003 <br />revegetation monitoring studies at the Seneca II-W Mine are presented in Tables 1 through 12. <br />Sampling data are summarized in Table 13. Data on species density by lifeform are tabulated for <br />sampled areas in Table 14. Data on relative cover by lifeform are compiled in Table 15. <br />Statistical adequacy of sampling is reviewed in Table 16. The list of plant species observed <br />• during these studies (reclaimed and reference areas) are included in Table 17 in Appendix 2. <br />Seed mixes used in the 1996 and 1999 reclamation areas are included for reference in Appendix <br />3. Photographs of representative locations within the reclaimed areas sampled in 2003, as well <br />as photographs of the Aspen, Mountain Brush, and Sagebrush reference areas are included in <br />Appendix 4. Graphic depiction of vegetption and climate data are presented in Figures 1 through <br />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. Cover percentages referred to in the following results as "percent of total vegetation cover" <br />are relative vegetation values. <br />1996 Reclaimed Area <br />(Photographs 1 through 4) <br />COVER (TABLE 1) <br />Native perennial cool season grasses dominated this area in 2003, composing an average of <br />40.1% of total vegetation cover. Within this lifeform, Agassiz bluegrass (Poa agassizensis), was <br />the most common species with about half of cover for the lifeform. Also observed were mountain <br />
