Calculation of 90 percent of the cover performance standard appropriate for 2011 sampling using the <br />highest possible value for the Mountain Brush Reference Area component is demonstrated below. <br />Aspen Reference Area Allowable All -Hit Herbaceous Cover' = 91.3% <br />Mountain Brush Reference Area Allowable All -Hit Herbaceous Cover' = 50.04% <br />Sagebrush Reference Area Allowable All -Hit Herbaceous Cover' = 30.1% <br />Steep Mountain Brush Reference Area Allowable All -Hit Herbaceous Cover' =32.2% <br />Western Wheatgrass/ Alkali Sagebrush Reference Area Allowable All -Hit Herbaceous Cover' = 45.4% <br />' Herbaceous cover adjusted by subtracting noxious weeds and annual /biennial plant cover in excess of 10% of the remainder. <br />90 percent of the Cover Standard for 2011 = <br />0.90* [0.110(91.3 %) +0.354(50.04 %) +0.313(30.1 %) +0.128(32.2 %) +0.104(45.4 %)] = 41.4 <br />The mean allowable all -hit herbaceous vegetation cover sampled in 2011 BRB -1 was 57.7 percent, <br />exceeding 41.4 percent, which is 90 percent of the upwardly adjusted cover performance standard. (see <br />also Figure C -1, Table C -1). This direct comparison of reclaimed area mean to standard is allowed under <br />DRMS rules (CDMG 2005 revised rule, 4.15.11 (2)(a)) when sample adequacy has been demonstrated for <br />the reclaimed area. Thus for 2011, successful revegetation with respect to allowable all -hit herbaceous <br />cover is indicated. [Note that were the Mountain Brush Reference Area mean not upwardly adjusted to the <br />maximum value for the calculation of the performance standard, 90% of the cover standard would have <br />come to 39.4 %]. <br />HERBACEOUS PRODUCTION <br />Calculation of 90 percent of the production performance standard appropriate for 2011 sampling is <br />demonstrated below. <br />Aspen Reference Area Allowable Herbaceous Production' = 1391.8 lbs/acre <br />Mountain Brush Reference Area Allowable Herbaceous Production' = 754.8 lbs/acre <br />Sagebrush Reference Area Allowable Herbaceous Production' = 963.6 lbs/acre <br />Steep Mountain Brush Reference Area Allowable Herbaceous Production' = 492.9 lbs/acre <br />Western Wheatgrass/ Alkali Sagebrush Reference Area Allowable Herbaceous Production' = 934.2 <br />lbs/acre <br />'Herbaceous production adjusted by subtracting annual /biennial plant production in excess of 10% of the remainder. Production by <br />noxious weed species is not collected. <br />25 <br />
