WPD secondary standard 1 (Standard S1). Sample adequacy based on woody plant density was <br /> achieved in the Fenced Upland "Concentration" area of the BRB-2. The mean density (3,137.6 <br /> stems per acre) exceeded the performance standard of 851 stems per acre, which is 90% of the <br /> secondary performance standard 1 (CDMG 2005 revised rule, 4.15.11 (2)(a)). Thus, revegetation <br /> success for WPD Secondary standard 1 has been met for 2015. <br /> WPD secondary standard 3 (Standard S3). The 2015 Fenced Aspen WPD data were first evaluated <br /> for normality using the Shapiro-Francia test. Based on the raw 2015 Fenced Aspen WPD data the <br /> normality test was not passed. Consequently a square root transformation was performed and the <br /> normality test was passed.Use of a reverse null t-test of the assertion that the BRB-2 Fenced Aspen <br /> Concentration Area mean exceeds 90% of the secondary standard 3 shown as follows: <br /> aF— (0.9= technical standard) <br /> (A <br /> tcalc = (52.6 — 29.2)/(20.7/ [301 "0.5 ) = 6.192 <br /> Since critical ttable= 0.854 (one-tailed, alpha = 0.2, 30-1 df) and t�ai. is greater than this critical <br /> value, reclamation success for Fenced Aspen "Concentration" area for Phase III in 2015 is <br /> demonstrated. It should be noted that the same results would have been achieved using raw values <br /> (tcalc= 5.483 which exceeds tt=0.854). Hence the WPD Secondary standard 3 has been met for <br /> 2015. <br /> 2016 Woody Plant Density Success Evaluation <br /> Woody plant density data are presented in the 2015/2016 report of the findings of testing for <br /> revegetation success for the Yoast BRB-2 Phase III and Phase II + III bond release area. These <br /> data tables are included here as Attachment D — Revegetation Success Supporting <br /> Documentation.As can be seen in Table 5,the 2,055.8 stems per acre observed in the background <br /> area far exceeds the 180 stems per acre(90 percent of the 200 stems per acre background standard) <br /> performance standard. <br /> Statistical testing for 2016 background area data is as follows. <br /> SL-7 - 20 <br />
