HERBACEOUS PRODUCTION <br />Calculation of 90 percent of the cover performance standard appropriate for 2011 sampling is <br />demonstrated below. <br />Mountain Brush Reference Area Allowable herbaceous production* = 835.1 lbs/acre <br />Sagebrush Reference Area Allowable herbaceous production *= 1286.5 lbs/acre <br />90 percent of the Production Standard = 0.90 [0.83(835.1) + 0.17(1286.5)] = 820.7 lbs/acre <br />* Herbaceous cover adjusted by subtracting noxious weeds and annual/biennial plant cover in excess of 10% of the remainder. <br />As can be seen in Figure 2, the 2011 BRB PSCM -1 mean allowable herbaceous production of 2815.8 <br />pounds per acre far exceeded 90 percent of the production performance standard (821 lb/ac). The <br />average annual and biennial sampled 2011 BRB PSCM -1 production was not greater than 10 percent of <br />total herbaceous production and therefore no "excess" annual /biennial production deduction was used in <br />2011. Noxious weed production was not collected. <br />Since the 2011 BRB PSCM -1 allowable herbaceous production exceeds 90 percent of the production <br />performance standard (Figure C -2, Table C -1), and sample adequacy has not been demonstrated (with a <br />minimum of 30 samples) (Table C -4), testing for reclamation success for Phase Ill is undertaken using a <br />reverse -null t -test (CDMG 2005 rules 4.15.1 (2)(c)). <br />A reverse -null t -test of the assertion that the 2011 BRB PSCM -1 allowable herbaceous production <br />exceeds from the Weighted Reference Area allowable herbaceous production performance standard is as <br />follows: <br />t, = <br />— (0.9 * Weighted Reference Area performanr_estandard) <br />VR) <br />26 <br />
