Consequently revegetation success for Phase Ill in BRB -5 <br />relative to the Sagebrush Reference Area is demonstrated. <br />Since the herbaceous production of BRB -5 has been shown to exceed both reference areas via the <br />above hypothesis tests, revegetation success is indicated for herbaceous production in 2012. <br />Figure C -3 and C -4 graphically presents the "Background" and "Concentration Area" woody plant density <br />averages for the 2012 BRB -5, respectively. As can be seen, the 210.4 stems per acre observed in the <br />Background area exceed the 90 stems per acre (90 percent of the 100 stems per acre background <br />standard) performance standard. The mean of 1,614.7 stems per acre observed in the Concentration <br />areas also well exceeds the 900 stems per acre (90 percent of the 1,000 stems per acre background <br />standard) performance standard. The total Concentration Area identified was 19.0 acres, or 7.1% of the <br />28 <br />
