Total cumulative#of native species*Z avg. reference area native species density(#species/100 <br /> M 2) <br /> *In the cumulative presence data from 2 m x 50 m samples associated with the collection of a statistically <br /> adequate sample of the reclaimed area. Alfalfa and/or cicer milkvetch are included, since these have <br /> often been included in seed mixes as nitrogen—fixers, due to the lack of suitable and available native <br /> nitrogen-fixers. <br /> If the total cumulative number of native species in the reclamation sampling exceeds the average number <br /> of native species per 100 m2 in the weighted average of the reference area sampling, then Test D is <br /> passed. <br /> Climatic Data <br /> Seneca Property (SPL) has historically provided precipitation data for the Seneca II/PSCM (1982-1989) <br /> and IIW Mines (1990-2010), however, data from the Yoast Mine is unavailable. Given the close proximity <br /> of the three mines, the Seneca II and Seneca IIW mine data were also used at Yoast when available. <br /> Precipitation data obtained from the NOAA administered Western Regional Climate Center(WRCC) for <br /> the nearby town of Hayden, Colorado (Station 053867), were used during the most recent years (2011- <br /> 2016). Since the long-term average for the mine specific data exists for only 29 years, the long-term <br /> average monthly precipitation data from Hayden (Station 053867)was used as an appropriate base for <br /> comparison. Temperature data from the Hayden station was used as well. <br /> RESULTS <br /> Sample data from 2016 are presented in Tables A-1 through A-7. Sampling data for 2016 are <br /> summarized in Appendix B. Data on cover are summarized in Table B-1. Data on species density by <br /> lifeform are tabulated for sampled areas in Table B-2. Data on relative cover by lifeform are compiled in <br /> Table B-3. Statistical adequacy of sampling is reviewed in Table B-4. The list of plant species observed <br /> during 2016 (reclaimed and reference areas) is included in Appendix C. Seed mixes used in the <br /> reclamation areas are included for reference in Appendix D. Photographs of representative locations <br /> within the reclaimed and reference areas sampled during the 2016 evaluation are included in Appendix E. <br /> Graphs of vegetation and climate data are presented in Figures B-1 a through B-8 of this report. <br /> In the plant 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.
