assumption that the standard was met is still valid based on statistical tests as discussed <br />in Section 6.0. Table 4 was generated using the formulas and statistical values <br />outlined in the 1995 CDMG Bond Release Guideline. <br />5.6 Plant Species I?iversity <br />General plant species diversity was derived from the 1996 cover data by <br />totaling the number of individual species recorded. Plant species were grouped <br />according to life-form and the 1996 results are included in Table 5. All of the <br />reference areas except for the Sagebrush type were slightly greater in diversity than <br />the reclaimed area. All of the study areas were dominated by perennial grasses and <br />forts. Lists of species observed in the reference azea samples aze included in <br />Appendix A, Part I. All plant species observed on the reclaimed azea, including those <br />recorded in the samples and other species observed during the course of field work, <br />aze listed in Appendix A, Part II. <br />Table 6 shows the 1980 plant species diversity for the affected premise <br />vegetation types and the 1996 data for the reclaimed azea. Only two of the premise <br />types (Chokecherry and Oak Brush) showed species diversity Beater than that of the <br />reclamation azea. The other two areas showed that the species diversity was equal to <br />or slightly lower than that of the reclaimed area. <br />Both Tables 5 and 6 demopstrate that a good diversity of plant species has been <br />established on the reclaimed area. The reclamation is dominated by perennial grasses <br />which made up the greatest percentage of the seed mixtures. None of the perennial <br />12 <br />
