Total cumulative # of native species* _> avg. reference area native species density (# species / 100 <br />m2) <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 IN 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-1a 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.
