• _ 1997 Data <br />The 1997 data (Table 4c) shows that all pazameters except shrub density for <br />reclamation were met. It is also assumed that the shrub density standazd was met as <br />discussed in Section 6.0. Statistical evaluations were not computed for the small non- <br />contiguous areas for the 1997 data due to the low number of samples collected. <br />5.6 Plant Species Dvversity <br />General plant species diversity was derived from the 1996 and 1997 cover data by <br />totaling the number of individual species recorded. Plant species were grouped according <br />to life-form and the results are included in Tables Sa, Sb, and Sc. <br />1996 Data <br />The original 1996 data (Table Sa) shows all of the reference azeas except for the <br />Sagebrush type were slightly greater in diversity than the reclaimed area. All of the study <br />areas were dominated by perennial grasses and forbs. <br />1996 Revised Data <br />The 1996 revised data (Table Sb) shows that all of the reference areas were greater <br />in diversity than the reclaimed areas. Perennial grasses and perennial forbs were the <br />dominant life-forms on all of the study areas. Comparisons with the small non-contiguous <br />azeas aze not valid due to the minimum numbers of samples collected. <br />1997 Data <br />Table Sc shows the 1997 species diversity data. The Chokecherry and sagebrush <br />reference areas showed slightly greater diversity than that of the random sampled <br />reclaimed azea. The Aspen and Oak Brush reference areas showed slightly lower diversity <br />31 <br />
