contributed 12.38 g/1/4mZ or 80.92 percent of the total forage production and perennial forbs <br />contributed 0.09 g/1 /4m2 or 19.08 percent of the total forage production. <br />The locations of the 30 production transects sampled on this site are shown on Map 7, Tipple <br />Reclamation - Vegetation Transect Location Map. The sample adequacy calculations in Table 2, <br />Kerr Mine Sample Adequacy Calculations, document that the number of production transects <br />required to characterize the perennial herbaceous forage production on this site at the 90 percent <br />statistical confidence interval was 113.4 transects. Since the reclaimed area production value <br />(19.36 g/1 /4m' or 690 pounds of air-dry forage per acre) exceeds the revegetation success <br />standard of 4.64 g/1/4m2 or 165.4 pounds of air-dry forage per acre, it can be concluded that this <br />area satisfies the sample adequacy requirements with respect to forage production. <br />Shrub Density. The shrub density counts obtained from the sampling of the 30 belt transects <br />taken in this area are summarized in Table 12, Tipple Reclamation - Shrub Density. The average <br />shrub density was determined to equal 196.03 shrubs per one hundred square meters or 7,933.3 <br />shrubs per acre. Rubber Rabbitbrush, Wyoming Big Sagebrush and Douglas Rabbitbrush were <br />the most commonly encountered shrubs. The revegetation shrub density success standard for this <br />reclaimed site is 1,500 stems per acre 37.06 stems per 100 m2 . Since this site averaged 7,933.3 <br />shrubs per acre and sample adequacy was achieved for shrub density sampling using the reverse <br />null statistical test, it can be concluded by direct comparison that this area satisfies the <br />revegetation success standard with respect to shrub density. <br />When IME sampled this site in 2005, they report that shrub density averaged 159.67 shrubs per <br />one hundred square meters or 6,461.8 shrubs per acre. <br />The locations of the 30 shrub density transects sampled on this site are shown on Map 7, Tipple <br />Reclamation - Vegetation Transect Location Map. Examination of the sample adequacy <br />calculations in Table 2, Kerr Mine Sample Adequacy Calculations, reveals the number of <br />samples required to characterize the shrub density on this reclaimed site at the 90 percent <br />statistical confidence interval was 3.83 transects. Since the actual shrub density counts on the <br />reclaimed site (7,933.3 shrubs per acre) exceeds the approved standard (1,500 stems per acre), <br />using the DRMS regulations, sample adequacy is achieved with 30 transects. <br />Species Diversity. The percent relative composition or cover values in Table 10, Tipple <br />Reclamation - Plant Cover, document that the three most dominant plant species growing on this <br />reclaimed area contribute a total of 54.79 percent of the total relative cover found on this site. <br />This value is above the minimum value of 54 and below the maximum value of 75 percent total <br />relative cover, required for successful reclamation by the Permit. All three life forms are <br />represented by the three most dominant plants and thus the life form requirement that at least one <br />of the three dominants must be a forb is satisfied. The minimum value contributed by the three <br />most dominant plants was 10.65 percent, which is also a forb and this value is well above the <br />minimum of 3 percent total relative cover required by the Permit. These revegetation monitoring <br />data from this site confirm that the skies diversity standards for this reclaimed site have been <br />satisfied. <br />12
