The woody plant density standards for the Southfield Mine and the Southfield loadout are as <br />follows: <br />On the Vento Portal and Refuse Pile Reclamation areas, the twelve shrub transplant areas <br />planted by the Colorado State Forest Service (1,843 shrubs and trees transplanted in May of <br />2004) comprise a total area of 6.23 acres. These transplant areas will be evaluated by <br />subdividing each of these areas with belt transects and by using a Trimble Model GeoXH <br />global positioning survey unit (or equivalent), which has a typical post -process data accurate <br />of plus of minus one meter, during each of the final two years of Phase III Final Bond Release <br />reclamation monitoring. Using this unit EFCI will sample every single woody plant <br />contained within the boundaries of these shrub transplant areas. Then based upon either the <br />contribution of the transplanted shrubs and trees, planted shrubs, or invading shrubs and trees, <br />a total of at least 1,843 woody plants will be present during each sampling period at the time <br />of final bond release sampling. <br />On all areas corresponding to the Refuse Pile Reclamation, which correspond to the <br />Grassland Pre -Disturbance plant community, an average of at least 250 woody plant stems per <br />acre will be present on these reclaimed areas during each of the final two years of Phase III <br />Final Bond Release reclamation monitoring. <br />On all reclaimed areas corresponding to the Vento Portal Reclamation area, which correspond <br />largely to the Pinyoh-Juniper/Ponderosa Pine Pre -Disturbance plant community, an average of <br />at least 800 woody plant stems per acre will be present on these reclaimed areas during each <br />of the final two years of Phase III Final Bond Release reclamation monitoring. <br />On the Corley property there will be no woody plant density revegetation success standard. <br />Because woody plant occurrence in the loadout area is very limited, woody plant sampling <br />data for the loadout area will be compared with the revised woody plant counts for the <br />corresponding reference area as documented in the baseline vegetation data. The revised <br />woody plant count for the loadout area is 6.3 (2 trees and 1 shrub on 0.48 acre area) stems per <br />acre. If the woody plant density (calculated on a stems per acre basis using woody plant <br />sampling data) for the loadout area is greater than or equal to the 90 percent confidence <br />interval for corresponding revised woody plant counts, revegetation will be deemed adequate <br />relative to woody plant density. <br />TR -45 2.05.4-27a Revised 07/24/15 <br />
