<br /> <br />4.0 SUCCESS COMPARISON <br />A summary of the success comparison for the bond release block is provided on the following pages <br />in Table 1 and Charts 5 through 9. Table 1 gives a quick indication of the overall success of the revegetation <br />units compared to reference area data and/or standards. Charts 5 through 9 provide a visual display of <br />the same comparisons. <br />The demonstration of adequacy and a minimum of 15 transects in each unit allow for a direct <br />comparison for cover, production, and woody plant density per Rule 4.15.11 (2)(a). With regard to <br />perennial lifeform ground cover, the Phase III Bond Release Block passed the success criterion of ≥17.8% <br />cover (90% of the reference area value) with 35.0% cover. With regard to diversity, the revegetated area <br />passed the three relative cover standards, having achieved a relative cover of ≥3.0% for three perennial <br />species, ≥3.0% relative cover for two perennial cool-season grass species, and no single species that <br />represented >60% relative cover. An evaluation of the remaining variables of production and woody plant <br />density also demonstrated that the revegetated area passed the success criterion of ≥66.4 pounds per acre <br />of perennial herbaceous production (90% of the reference area value) with 375 pounds per acre and the <br />woody plant density standard of ≥500 stems per acre with 1,733 stems per acre. <br />This review of collected data demonstrates the success and utility of the revegetated area, especially <br />given vegetative ground cover and favorable results with regard to production and woody plant density. <br />Inspection of Plates 1 through 4 in comparison to Plates 5 and 6 provides visual evidence of this utility. <br />Field studies have shown that the target reclaimed plant communities have progressed sufficiently to be <br />considered for Phase III Bond Release. Ground cover of perennial plants within the reclaimed area is <br />comparable to adjacent undisturbed native communities and plant succession is occurring and progressing <br />in a positive direction, indicating that plants are self-sustaining. A Year 2 (final) vegetation evaluation of <br />this Phase III Bond Release Block is recommended to take place in June of 2017. <br />CEDAR CREEK ASSOCIATES, Inc.16 Munger Canyon Mine - 2016 <br />Phase III Bond Release Report
