Alternative Test D): Native Species Presence Assessment <br />The third alternative assessment of the species diversity of reclaimed lands makes direct reference to the <br />presence of native western North American plant species in reclaimed areas. <br />Total cumulative # of native species' _? avg. reference area native species density (# species / 100 <br />sq.m.) <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 and including alfalfa and /or cicer milkvetch, which have often <br />been included in seed mixes as nitrogen — fixers, due to the lack of suitable and available native nitrogen - <br />fixers. <br />If the total cumulative number of native species in the reclamation sampling exceeds the average number <br />of native species per 100 sq.m. in the weighted average of the reference area sampling, then Test D is <br />passed. <br />RESULTS <br />Sample data from 2014 are presented in Tables A -1 through A -6 and are summarized in Appendix B. <br />Data on cover are summarized in Table B -1. Data on species density by lifeform are tabulated for <br />sampled areas in Table B -2. Data on relative cover by lifeform are compiled in Table B -3. Statistical <br />adequacy of sampling is reviewed in Table B -4. The list of plant species observed during (reclaimed and <br />reference areas) is included as Table C -1. Seed mixes used in the reclamation areas are included for <br />reference in Appendix D. Photographs of representative locations within the reclaimed areas sampled in <br />2014, as well as photographs of the Reference areas, are included in Appendix E. Graphs of vegetation <br />and climate data are presented in Appendix H 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. Unless <br />otherwise stated, all cover values reported below are for all -hit data. Percentages are rounded to one <br />decimal place to facilitate discussion of the results. <br />10 <br />
