4.4 Total Perennial Diversity by Lifeform Success Comparisons <br />The approved diversity standards for Snowcap Mine is to achieve at least 0.5% total relative cover <br />with at least two species present in the reclamation for each of the following lifeforms: perennial cool - <br />season grasses, perennial warm - season grasses, and perennial forbs and sub -shrub species. Sampling <br />efforts in 2011 and 2012 indicate that the bond release areas are performing well in this regard and pass <br />all diversity standards. <br />As indicated on Tables 1 and 2 and Charts 4 through 6, evaluation of diversity on the Phase III bond <br />release areas in 2011 revealed 11 perennial cool- season grasses observed and 1.2% relative cover in <br />Greasewood Comparison Revegetation Areas and 18 perennial cool- season grasses observed and 12.7% <br />relative cover in Shadscale Comparison Revegetation Areas. There were three perennial warm- season <br />grasses observed in the Greasewood Comparison Revegetation Areas and four perennial warm- season <br />grasses in the Shadscale Comparison Revegetation Areas, contributing 1.4% and 5.3% relative cover, <br />respectively. Likewise, there were 12 perennial forbs and sub - shrubs observed in the Greasewood <br />Comparison Revegetation Areas and 20 perennial forbs and sub - shrubs in the Shadscale Comparison <br />Revegetation Areas, contributing 7.0% and 10.8% relative cover, respectively. <br />5 <br />4 <br />s <br />Vg ... _.... ._. <br />i <br />a <br />■ <br />°L. 2 <br />c <br />� 1.2 <br />a` <br />1 r- <br />Chart 4 <br />Bond Release Evaluation - Success Comparisons <br />Diversity- Total Perennial Cool Season Grass Relative Cover- 2011 and 2012 <br />12'7 I Success Standard - 20.5'V.TOtal 15.5 <br />Perennial Cool Season Grass <br />Relative Cover <br />0.5 <br />o• <br />Greasewood Shadscale Success Standard <br />Comparison Comparison <br />Revegetation Revegetation <br />2011 <br />1.2 <br />0.5 <br />Greasewood Shadscale Success Standard <br />Comparison Comparison <br />Revegetation Revegetation <br />2012 <br />CEDAR CREEK ASSOCIATES, Inc.
