This <br />provides additional demonstration that the reclaimed areas are well established. <br />2011 Herbaceous Production Success Evaluation <br />The 2011 herbaceous production values for the mountain brush and sagebrush reference areas <br />are summarized in Table 6 above. Calculation of 90 percent of the cover performance standard <br />appropriate for 2011 sampling is demonstrated below. <br />10 <br />
