• <br />are presented in Appendix Table 2.04.10B -2, Garvey Property 2011 - Intensively Managed <br />Irrigated Pasture - Production. The average total production on this site was determined to equal <br />193.87 g/1 /4m or 6,909.7 pounds of air -dry forage per acre. <br />Perennial grasses contributed an average of 160.26 g/1 /4m or 82.66 percent of the total <br />herbaceous forage production. Perennial forbs, contributed an average of 33.61 g/1 /4m or <br />17.34 percent of the total herbaceous production (Appendix Table 2.04.10B -2, Garvey Property <br />2011 - Intensively Managed Irrigated Pasture - Production.) <br />The sample adequacy calculations, documents that forage production on this site at the 90 <br />percent confidence interval was determined to equal 23.44 transects. The locations of the 30 <br />production transects are shown on Appendix Map 2.04.10 -6, 2011 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. When sampled in 2010, <br />average total herbaceous production on this site was determined to equal 168.32 g/1 /4m or <br />5,998.9 pounds of air -dry forage per acre. In 2010, perennial grasses contributed an average of <br />10141.23 g/1 /4m or 83.91 percent of the total herbaceous forage production. Perennial forbs, <br />contributed an average of 27.08 g/1 /4m or 16.09 percent of the 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 -6, 2011 Intensively Managed Irrigated Pasture - Vegetation <br />S Transect Map. Since there were no shrubs or woody plants encountered in the sampling of this <br />vegetation type in 2011, 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 />• <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. In the 2009 and 2010 sampling of this site, no shrubs or woody plants were encountered in <br />the sampling of this site. <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 described in the Permit text relative to section 2.04.10. The <br />owners of this land desire that these areas be reclaimed to a similar condition following mining <br />and reclamation. <br />This evaluation contains the third year's monitoring results for this vegetation type.
