sampling on the IP -3 tract. <br />The plant cover data for the IP -2 site are found in 2009 report Appendix A. Table A2, <br />Vegetation cover data for each transect, reclaimed area IP -2, have been modified to <br />confirm with the current bond release requirements as found on page 10 of the DRMS <br />Bond Release Guideline and to be consistent with the current definitions found in the <br />NH2 Mine Permit. These data are presented in Appendix 1 - Table 6, Irrigated Pasture - <br />IP 21.5 Acre Reclamation Phase III Study Area - Second Year - 2009 Plant Cover. <br />"Allowable plant cover" averaged 80.80 percent. According to the sample adequacy <br />equation found in Rule 4.15.11(2)(a), sample adequacy at the 90 percent confidence level, <br />for "allowable plant cover" was achieved with 5.1 transects and 15 transects were <br />sampled. <br />The plant cover data for the IP -3 site are found in Appendix A. Table A3, Vegetation <br />cover data for each transect, reclaimed area IP -3 of the 2009 report and have been <br />modified to confirm with the current bond release requirements as found on page 10 of <br />the DRMS Bond Release Guideline and to be consistent with the current definitions <br />found in the NH2 Mine Permit. These data are presented in Appendix 1 - Table 8, <br />Irrigated Pasture - IP - 3 20.5 Acre Phase III Study Area - First Year's - 2009 Plant <br />Cover. "Allowable plant cover" averaged 88.13 percent. According to the sample <br />adequacy equation found in Rule 4.15.11(2)(a), sample adequacy at the 90 percent <br />confidence level, for "allowable plant cover" was achieved with 5.1 transects and 15 <br />transects were sampled. <br />The second year's production, data for the Irrigated Pasture Reclaimed Area IP -2 are <br />found in Appendix A. Table A5, Vegetation production data for each plot, reclaimed area <br />IP -2, of the 2oo9 report and have been modified to confirm with the current bond release <br />requirements as found on page 10 of the DRMS Bond Release Guideline and to be <br />consistent with the current definitions found in the NH2 Mine Permit. The production of <br />desirable perennial grasses and perennial forbs are found in Appendix 1 - Table 7, <br />Irrigated Pasture - IP - 2 Reclaimed Area Phase III 21.5 Acre Study Area - 2009 <br />Production. Forage production averaged 68.37 grams per one quarter square meter or <br />2,436.7 pounds of air -dry forage per acre. According to the sample adequacy equation <br />found in Rule 4.15.11(2)(a), sample adequacy at the 90 percent confidence level, for <br />"desirable forage production," was determined to equal 44.7 transects and 30 transects <br />were sampled. <br />The plant cover data for this site are found in Appendix A. Table A6, Vegetation cover <br />data for each transect, reclaimed area IP -3 of the 2009 report and have been modified to <br />confirm with the bond release requirements as found on page 10 of the DRMS Bond <br />Release Guideline and to be consistent with the current definitions found in the NH2 <br />Mine Permit. These data are found in Appendix 1 -Table 8, Irrigated Pasture 20.5 Acre <br />Reclamation Phase III Study Area - First Year - 2009 Plant Cover. The percent <br />absolute cover by species, rock, bare ground, litter and relative cover are found in <br />SL -14 03DEC12.wpd 43 <br />
