2015 Production Success Evaluation <br /> Calculation of 90 percent of the production performance standard relative to 2015 sample data is <br /> demonstrated below. <br /> Aspen Reference Area Allowable Herbaceous Production' = 828.1 lbs/acre <br /> Mountain Brush Reference Area Allowable Herbaceous Production' = 648.0 lbs/acre <br /> Sagebrush Reference Area Allowable Herbaceous Production' = 1188.5 lbs/acre <br /> Steep Mountain Brush Reference Area Allowable Herbaceous Production' = 518.0 lbs/acre <br /> 'Herbaceous production adjusted by subtracting annual/biennial plant production in excess of 10%of the <br /> remainder.Production by noxious weed species is not collected. <br /> 90 percent of the production standard for 2015 = <br /> 0.90 [0.244(828.1) + 0.489(648.0) + 0.240(1188.5) + 0.027(518.0) = 736.4 lbs/acre <br /> The 2015 BRB-2 reclaimed area mean allowable herbaceous production of 1,709.2 pounds per <br /> acre (Table 7) far exceeded 90 percent of the production performance standard of 736.4 pounds <br /> per acre. The average herbaceous production by annuals and biennials sampled in the BRB-2 was <br /> less than 10% of total herbaceous production (149.0 lbs/acre non-noxious annuals and biennials). <br /> Therefore an"excess" annual/biennial production deduction was not used in 2015. <br /> The 2015 BRB-2 allowable herbaceous production exceeded 90 percent of the production <br /> performance standard, but sample adequacy was not demonstrated in either the reclaimed or the <br /> reference areas (minimum of 30 samples—see Table C4 in Attachment D). Therefore reclamation <br /> success for Phase III is demonstrated by passing a one sample t-test of the"reverse null"hypothesis <br /> (CDMG 2005 revised rule, 4.15.11 (2)(c)). The 2015 BRB-2 production data were first evaluated <br /> for normality of distribution using the Shapiro-Francia test(Table 3 and accompanying discussion, <br /> Page 26 of the Vegetation Report contained in Attachment D). This test was not passed. Following <br /> a square root transformation of the data, the test was passed. Hypothesis testing was conducted <br /> using square root transformed data for both the BRB-2 production data and the production <br /> technical standard. <br /> SL-7 - 14 <br />
