The sample adequacy calculations, documents that forage production on this site at the 90 <br />percent confidence interval was determined to equal 16.8 transects. The locations of the 30 <br />production transects are shown on Appendix Map 2.04.10 -5, 2010 Intensively Managed Irrigated <br />Pasture - Vegetation Transect Map. <br />When this site was sampled in 2009, the average total production on this site was determined to <br />equal 179.21 g/1/4m or 6,387.0 pounds of air -dry forage per acre. In 2009, perennial grasses <br />contributed an average of 102.33 g/1 /4m or 57.10 percent of the total herbaceous forage <br />production. Perennial forbs, contributed an average of 76.88 g/1/4m or 42.90 percent of the <br />total herbaceous production. <br />Shrub Density. There were no shrubs or woody plants encountered in the sampling of the <br />fifteen cover transects. The locations of the 15 shrub density transects sampled on this site are <br />shown on Appendix Map 2.04.10 -5, 2010 Intensively Managed Irrigated Pasture - Vegetation <br />Transect Map. Since there were no shrubs or woody plants encountered in the sampling of this <br />vegetation type in 2010, the sample adequacy calculations document that the number of samples <br />required to describe the shrub density on this area at the 90 percent confidence interval was 0 <br />transects. <br />When this site was sampled in 2009, the average shrub density on this site is 0.73 shrubs per 100 <br />m or 29.8 woody plants per acre. Sandbar willow was the most commonly encountered woody <br />plant. <br />REVEGETATION SUCCESS <br />As allowed by Section 4.15.7(2)(d)(v) and on pages 11 and 12 of the Division's Guidelines for <br />Compliance with Land Use and Vegetation Requirements for Coal Mining, WFC is proposing <br />to use the "historic record" method with three years of predisturbance baseline data to quantify <br />the successfulness of final revegetation efforts on the Intensively Managed Irrigated Pasture <br />vegetation type. <br />Disturbance to all lands corresponding to the Intensively Managed Irrigated Pasture vegetation <br />type (IMIP) are shown on permit Map 2.04.10 -1, Permit Area Vegetation Map. This vegetation <br />type is found only on lands owned and managed by the Garvey Brothers and differs from regular <br />irrigated pasture for the reasons previous described. The owners of this land desire that these <br />areas be reclaimed to a similar condition following mining and reclamation. <br />As allowed in the Division's Guidelines for Compliance with Land Use and Vegetation <br />Requirements for Coal Mining, the plant cover and forage production data will be sampled for <br />three years and these corresponding cover and production values will be averaged into an overall <br />mean value which will then be used as the revegetation success standard for cover and <br />herbaceous production for this vegetation type. These data will also be used to calculate the final <br />species diversity standard for this vegetation type. This evaluation contains the second year's <br />monitoring results for this vegetation type. The third years monitoring efforts for this site, will <br />be supplied to the Division in connection with the New Horizon North Mine - Annual <br />Reclamation Monitoring Report and in appropriate Permit page modifications will be made once <br />the third year's monitoring data are available.. <br />6 <br />
