90 percent of the production standard for 2018= <br /> 0.90[0.110(973.0)+0.345(689.0)+0.313(824.1)+0.128(697.4)+0.104(777.7)] = 695.5 lbs/acre <br /> The 2018 BRB-5 reclaimed mean allowable herbaceous production of 1862.0 pounds per acre (Table 8) <br /> far exceeds 90 percent of the herbaceous production performance standard of 695.5 lbs/acre. <br /> Since the 2018 BRB-5 allowable herbaceous production exceeds 90 percent of the production <br /> performance standard (Figure C-2, Table C-1 of Attachment F), and sample adequacy has not been <br /> demonstrated in either the reclaimed or the reference areas of the Aspen and Sagebrush reference areas <br /> (minimum of 30 samples) (Table C-4 of Attachment F), Thus, reclamation success for Phase III BRB-5 <br /> has been demonstrated by passing a one sample t-test of the "reverse null" hypothesis (CDMG 2005 <br /> revised rule, 4.15.11 (2)(c)). The BRB-5 production data were first evaluated for normality using the <br /> Shapiro-Francia test. Based on the allowable herbaceous production data; the normality test was passed. <br /> See supporting details and methods in the full 2015/2016 Testing for Revegetation Success Report in <br /> Attachment F-2018-2019 BRB-5 Revegetation Success Supporting Documentation. <br /> A one-sample t-test of the"reverse null" hypothesis of the assertion that the 2018 BRB-5 total allowable <br /> herbaceous production (pounds per acre)is indistinguishable from the area weighted average of the <br /> Extended Reference Area allowable herbaceous production is as follows: <br /> x — (0.9 * technical standard) <br /> tcalc = / s <br /> l�-) <br /> 1862.0 — 695.5�� <br /> tcalc = (828) = 7.969 <br /> 32 <br /> Since critical t= 0.853 (one-tailed, alpha= 0.2, 32-1 df)is exceeded by tcalc (7.969), the hypothesis of no <br /> difference is rejected and reclamation success for 2018 BRB-5 production under Phase III is <br /> demonstrated. <br /> 2019 Production Success Evaluation <br /> Calculation of 90 percent of the production performance standard relative to the 2019 BRB-sample data is <br /> demonstrated below. <br /> Aspen Reference Area Allowable All-Hit Herbaceous Production' = 883.7 lbs/acre <br /> Mountain Brush Reference Area Allowable All-Hit Herbaceous Production' = 547.9 lbs/acre <br /> Sage Brush Reference Area Allowable All-Hit Herbaceous Production' = 907.1 lbs/acre <br /> Steep Mountain Brush Ref.
