cover performance standard) and success is demonstrated. This direct comparison of reclaimed <br />area mean to standard is allowed under DRMS rules (CDMG 2005 revised rule, 4.15.11 (2)(a)). <br />[Note that were the Mountain Brush Reference Area mean (28.85%) not upwardly adjusted to <br />the maximum value (32.1%) for the calculation of the performance standard, 90% of the cover <br />standard would have been lower at 31.5%]. <br />2014 <br />Calculation of the cover performance standard for 2014 sampling data is demonstrated below. <br />Aspen Reference Area Allowable All -Hit Herbaceous Cover' = 89.3% <br />Mountain Brush Reference Area Allowable All -Hit Herbaceous Coverl = 47.9%2 <br />Sagebrush Reference Area Allowable All -Hit Herbaceous Cover' = 35.4% <br />Steep Mountain Brush Reference Area Allowable All -Hit Herbaceous Cover' = 18.1% <br />1 Herbaceous cover adjusted to allowable by subtracting noxious weeds and annual/biennial <br />plant cover in excess of 10% of the remainder. <br />'Highest possible value of the true mean calculation <br />The calculation of 90 percent of the 2014 Cover Standard = <br />0.90* [0.244(89.3%) +0.489(47.9%) +0.24(35.4%) +0.027(18.1%)] = 48.8 <br />The mean allowable all -hit herbaceous vegetation cover sampled in 2014 BRB-1 was 60.6%, <br />exceeding 48.8%, which is 90% of the upwardly adjusted cover performance standard. (see <br />Table C-1 in Attachment D). This direct comparison of reclaimed area mean to standard is <br />allowed under DRMS rules (CDMG 2005 revised rule, 4.15.11 (2)(a)) when sample adequacy <br />has been demonstrated for the reclaimed area. Thus fdr 2014, successful revegetation for <br />allowable all -hit herbaceous cover is indicated. [Note that were the Mountain Brush Reference <br />Area mean not upwardly adjusted to the maximum value for the calculation of the performance <br />standard, 90% of the cover standard would have been lower at 45.6%]. <br />Successful revegetation for the parameter of cover was demonstrated in both 2012 and 2014. <br />PRODUCTION <br />The Yoast herbaceous production standard and success evaluation is based on reference area <br />SL -6 - 12 <br />
