For Alternative Test C, a similarity index test was conducted to compare the BRB5 to the ERA life form <br /> species density values. CCAI noted the performance standard for this test is 90%of 70% (63%),however in <br /> accordance with Tab 22,page 12 the performance standard should be 90%of 75% (67.5%). The similarity <br /> index was 86% and 87%in 2018 and 2019 respectively which exceeded the approved success standard of <br /> 67.5%. Alternative Test C was passed for both 2018 and 2019. <br /> For Alternative Test D,the total number of native species encountered at an adequate number of samples <br /> within BRB5 (based on allowable all-hit herbaceous cover and species density),was compared to the area <br /> weighted native species density standard(based on the extended reference areas). In 2018 the total number <br /> of native species encountered in the first sixteen 100m2 samples was 56. In 2018 the total number of native <br /> species encountered in the first fourteen 100m2 samples was 56. The 2018 area weighted native species <br /> density standard was 26.7 species per 100 m2. In 2019 the total number of native species encountered in the <br /> first fourteen 100m2 samples was 62. In 2019 the total number of native species encountered in the first <br /> seven 100m2 samples was 44. The 2019 area weighted native species density standard was 25.2 species per <br /> 100 m2. Alternative Test D is passed for the 2018 and 2019 data. <br /> In summary, Mandatory Test A was passed as were Alternative Tests B, C and D. Thus,the species diversity <br /> test as a whole is passed for the 2018 and 2019 BRB-5 and revegetation success for species diversity for <br /> Phase III is demonstrated. <br /> Conclusion <br /> The applicable revegetation success standards for BRB5 have been met. Based on this finding,the applicant <br /> has successfully established diverse vegetation that will be conducive to the post mine land use of livestock <br /> grazing and wildlife habitat. According to SPL, livestock grazing has been conducted on the mine's <br /> reclaimed lands since 2007 and stocking rates have been developed using ongoing revegetation monitoring <br /> data. SPL reports on grazing practices occurring at the site in the annual reclamation reports. Also,wildlife <br /> species have been observed by DRMS staff utilizing the reclaimed area. Given the findings in this document <br /> and the documented use of the reclaimed area for livestock grazing and wildlife, it appears the post mine <br /> land use has been achieved.
