The 2014 herbaceous production values for the mountain brush and sagebrush reference areas <br />are summarized in Table 4 above. Calculation of 90 percent of the cover performance standard <br />appropriate for 2014 sampling is demonstrated below. <br />Mountain brush reference area allowable herbaceous production = 596.0 lbs/acre <br />Sagebrush reference area allowable herbaceous production = 1602.4 lbs/acre <br />90 percent of the Production Standard = 0.90 [0.83(596.0) + 0.17(1602.4)] = 690.4 lbs/acre <br />The 2014 Phase III BRB PSCM-2 mean allowable herbaceous production of 1687.1 pounds per <br />acre (Table 3) exceeds 690.4 pounds per acre (90 percent of the production performance <br />standard). The average 2014 annual and biennial production sampled in BRB PSCM-2 was not <br />greater than 10 percent of total herbaceous production and therefore no "excess" <br />annual/biennial production deduction was required in 2014. Noxious weed production was not <br />collected, however the introduced annual grass cheatgrass and introduced perennial grass bulbous <br />bluegrass were deducted to account for the C -list noxious weed species. <br />While the 2014 BRB PSCM-2 allowable herbaceous production exceeded 90 percent of the <br />production performance standard, sample adequacy was not demonstrated with a minimum of 30 <br />samples taken in either the reclaimed or the reference areas. Therefore reclamation success for <br />Phase III 2014 herbaceous production is demonstrated by passing a one -sample t-test of the <br />Reverse Null Hypothesis (CDMG 2005 proposed rules revisions 4.15.1 (2)(c)). The BRB PSCM- <br />2 production data were first evaluated for normality using the Shapiro-Francia test. Based on the <br />BRB PSCM-2 production data the normality test was not passed. Consequently a square root <br />transformation was performed and the normality test was passed. Calculations were undertaken <br />using square root transformed data for both the BRB PSCM-2 production data and the <br />production technical standard. Please refer to pages 25 and 26 and Table 3 in the vegetation <br />success evaluation report contained in Attachment D for details and discussion. <br />A one -sample t-test of the "reverse null" hypothesis asserting that the BRB PSCM-2 allowable <br />herbaceous production is indistinguishable from the weighted average Reference Area allowable <br />herbaceous production is as follows (data are square roots of oven -dry gm/0.5square meter data <br />for both the BRB PSCM-2 production data and the production technical standard): <br />
