Successful reclamation for cover in all permanently reclaimed areas in the tie-across haul road <br />corridor will be measured as follows. For all permanently seeded upland areas (Seed Mix No. 1 <br />appliedl, the total vegetation cover measured from the low sagebrush reference area will be <br />compared to the total vegetation cover measured from the upland reclaimed areas. Cover for <br />these upland revegetated areas will be considered acceptable if it is not less than 90 percent of <br />the cover as determined from the low sagebrush reference area with 90 percent statistical <br />confidence. The remaining permanently seeded areas will be in lowland areas or drainages. <br />The meadow reference area will be used for cover comparisons in these reclaimed lowland or <br />drainage areas. Cover for these reclaimed areas will be considered acceptable if it is not less <br />than 90 percent of the cover as determined from the meadow reference area with 90 percent <br />statistical confidence. <br />Cover will be measured as described in Sampling Parameters and Sampling Methods in the <br />Revegetation Monitoring section presentetl earlier in this Tab. All sample points will be <br />randomly located. <br />Cover will not be evaluated for the croplantl portion of the reclaimed haul road. This is based <br />on Rule 4.15.9 which states that success of reclamation for cropland will be based on <br />production only. <br />Production Reclamation success for production in the mine area will be evaluated by <br />comparing herbaceous production in the reclaimed areas to the weighted herbaceous production <br />value determined from the extended reference area. <br />Herbaceous production will be estimated by clipping the current year's above ground <br />herbaceous biomass in randomly located 1/2mZ-1mZ sample plots. Fencing or exclosures will <br />be used to exclude livestock prior to sampling, where necessary. Herbaceous production from <br />the reclaimed lands being evaluated for reclamation success will be compared to the weighted <br />production value determined from the extended reference area vegetation types described under <br />cover and their relative areal extent in the premining surface area. The weighted herbaceous <br />production value will be determined by taking the herbaceous production value for each <br />reference area type and multiplying by the acreage occupied by the type in the premining <br />surface area. The products of each type will be added and then divided by the acreage total of <br />the reference area types in the premining surface area to arrive at the weighted value. <br />Reclamation success for herbaceous production shall be met <br />41 Revised 1 /99 <br />
