The locations of the 10 production transects sampled on this site in 2010 are shown on Map 2, <br />Loadout Reclamation - Vegetation Transect Location Map. The sample adequacy calculations in <br />Table 2, Southfield Mine Sample Adequacy Calculations, document that the number of <br />production transects required to characterize this site at the 90 percent confidence interval was <br />54.9 samples. <br />Shrub Density. The shrub density counts obtained from the sampling of the 10 belt transects <br />sampled on the Loadout Reclamation in 2010 are summarized in Table 11, Loadout Reclamation <br />- Shrub Density. The average shrub density was determined to equal 4.10 shrubs per one <br />hundred square meters or 165.8 shrubs per acre. Rubber Rabbitbrush and Fourwing Salt were the <br />only shrubs encountered in the shrub density sampling. <br />When this site was sampled in 2006, the shrub density averaged 4.43 shrubs per one hundred <br />square meters or 179.3 shrubs per acre. Rubber Rabbitbrush and Fourwing Salt were the only <br />shrubs encountered in the shrub density sampling. <br />According to the Southfield Mine Permit, the revegetation shrub density success standard for the <br />Loadout site is 6.3 stems per acre. Since this site averaged 179.3 stems per acre, it can be <br />concluded that this area satisfies the revegetation success standard with respect to shrub density. <br />Species Diversity. The percent relative composition or cover values in Table 9, Loadout <br />Reclamation - Plant Cover, document that the four most dominant plant species growing on this <br />reclaimed site contributed a total of 74.61 percent of the total relative cover found on this site. <br />This is well within the maximum value of 80 percent required by the Permit. The two most <br />dominant warm season grass species contributed 27.29 percent of the total relative cover found <br />on this site which is well below the 50 percent required by the Permit. These revegetation <br />monitoring data from this site confirm that the species diversity standards for this reclaimed site <br />based upon the 2010 revegetation monitoring are satisfied with respect to the four dominant but <br />are deficient with respect to the warm season species. <br />Conclusions <br />Three reclaimed areas at the Southfield Mine, the Vento Reclamation, the Corley Reclamation <br />and the Loadout Reclamation were sampled in 2010 during this interim reclamation monitoring <br />effort. As recommended by the Division's Vegetation Guideline, a total of 10 cover, production <br />and shrub density transects were sampled on each reclaimed site. Sample adequacy was <br />achieved for plant cover for all of the sites sampled in this monitoring effort. On all three sites, <br />the plant total plant cover growing on the revegetated sites exceeds the probable revegetation <br />success standard and it can be determined that the total plant cover growing on these sites is <br />considered successful with respect to the revegetation success standard for plant cover. <br />Sample adequacy was achieved for total herbaceous production only on the Corley Reclamation <br />site, but was not achieved on the Vento Reclamation or the Loadout Reclamation with the <br />13 <br />
