In 2005, perennial grasses contributed an average. of 19.35 g/1/4mZ or 66.00 percent of the forage <br />production and perennial forbs, contributed 9.96 g/1/4mZ or 34.001 percent of the forage <br />production on this area. In 2004, perennial grasses produced 24.52 g/1/4mZ or 72.59 percent and <br />perennial forbs, contributed 9.26 g/1/4mZ or 27.41 percent of the forage producfion. The <br />revegetation forage production success standard for the Raton Creek Mine is 300 pounds of air <br />dry forage per acre. Since this site in 2005 was detemrined to average 1,045.3 pounds of air dry <br />forage per acre and in 2004 averaged 1,203.9 pounds of air dry forage per acre, it can be <br />concluded that this area satisfies the revegetation success standard with respect to forage <br />production during both years of monitoring. <br />The locations of the 30 production transects sampled on this site are shown on Map 1, Raton <br />Creek Mine - 2005 Vegetation Transect Location Map. Copies of the individual field data sheets <br />for the forage production sampling of this site are found in Exhibit B -Copies of the Raton <br />Creek Mine - 2005 -Production Field Data Sheets. The sample adequacy calculations in Table 2, <br />Raton Creek Mine Sample Adequacy Calculations, documents that the number of production <br />transects required to characterize this site at the 90 percent confidence interval was 67.6 <br />transects. Since the reclaimed area production at the Raton Creek Mine in 2005 and 2004 <br />(1,045.3 pounds and 1,203.9 pounds, respectively) is greater than the revegetation success <br />standard (300 pounds per acre,) it can be concluded that the permanent reclaimed areas on the <br />Raton Creek Mine exceeds the forage production revegetation success standard and using the <br />"reverse null hypothesis" contained in the Division's proposed regulations, sampling can stop at <br />30 transects. <br />Shrub Density. The shrub density counts obtained from the 30 belt transects sampled on the <br />Raton Creek Mine in 2005 are summarized in Table 5, Raton Creek Mine - 2005 -Shrub <br />Density. The average shrub density from the 2005 sampling was calculated to equal 14.53 shrub <br />stems per one hundred square meters. In 2004 the sampling of 250 shrub density transects was <br />found to yield an average of 5.65 shrub stems per one hundred square meters or 228.6 shrub <br />stems per acre. Rubber Rabbitbrush, Fourwing Saltbush and VJinterfat were the most commonly <br />encountered shrubs. The revegetation shrub density success standard for this area as contained in <br />the recently submitted Technical Revision is for a minimum of at least 167 shrubs per acre <br />(4.1265 shrubs per 100 square meters) to be found on at least 26.26 percettt of the reclaimed <br />area. The remaining 73.74 percent of the reclaimed area has no shrub density standard since this <br />area was disturbed prior to being pemutted and as explained in the TR has no shrub density <br />standard. Exa_min~on of Table 5, Raton Creek Mine - 2005 -Shrub Density reveals that 12 of <br />the 30 traosects (40 percent of the transects sampled) exceeded the proposed woody plant <br />density standard of 167 shrubs per acre (4.1265 shrubs per 100 square meters). These data <br />document that the proposed shrub density standard is satisfied in the 2005 shrub density <br />sampling. <br />The locations of the 30 shrub density transects sampled at the Raton Creek Mine are shown on <br />Map 1, Raton Creek Mine - 2005 Vegetation Transect Locafion Map. Copies of the individual <br />field data sheets for the woody plant density sampling for this site are found in Exhibit C - <br />Copies of the Raton Creek Mine - 2005 -Shrub Density Field Data Sheets.
