2014 sampling is demonstrated below based on the weight averaged reference area data. The <br />weighting contribution is mountain brush 83% and sagebrush 17%. <br />2012 Cover Success Evaluation <br />2012 Mountain Brush Reference Area allowable first hit herbaceous cover* 8.7 x 2 = 17.4% <br />2012 Sagebrush Reference Area allowable first hit herbaceous cover 28.3 x 2 = 56.6% <br />* Herbaceous cover adjusted by subtracting noxious weeds and annuall biennial plant cover in excess of 10% of the <br />remainder, excluding cover by Collomia lineans. The latter is a native forb with little or no weediness to its nature whose <br />presence clearly does not quali as any sora of "defect" in the revegetation. On the contrary this succulent plant likely is an <br />important item of forage foryoung birds includinggrouse in the spring months. <br />90 percent of the Cover Standard = 0.90 [0.83(17.4) + 0.17(56.6] = 21.7% <br />The 2012 Phase III bond release BRB PSCM-2 sampling at thirty-five (35) random locations <br />resulted in an allowable first hit herbaceous cover value of 32.4% which exceeds the 90 percent <br />cover standard value of 21.7% and demonstrates success for cover in 2012. <br />2014 Cover Success Evaluation <br />2014 Mountain Brush Reference Area allowable first hit herbaceous cover 23.67 x 2 = 47.3% <br />2014 Sagebrush Reference Area allowable first hit herbaceous cover 41.8 x 2 = 83.6% <br />90 percent of the Cover Standard = 0.90 [0.83(47.3) + 0.17(83.6] = 48.1% <br />The 2014 Phase III bond release BRB PSCM-1 sampling at thirty-two (32) random locations <br />resulted in an allowable first hit herbaceous cover value of 47.09% failing to exceed 48.1 percent, <br />which is 90 percent of the cover performance standard. Since the BRB PSCM-2 allowable <br />herbaceous cover does NOT exceed 90 percent of the cover performance standard, and sample <br />adequacy has been demonstrated in both the reclaimed and the reference areas (minimum of 30 <br />samples), a one -sample t-test of the "classic" null hypothesis asserting that the BRB PSCM-2 <br />allowable herbaceous first -hit cover is indistinguishable from the 2014 weighted average <br />Reference Area allowable herbaceous first -hit cover follows. Note that 12.7 is the standard <br />deviation for allowable first -hit cover. <br />
