landscape, the above factors are a significant barrier towards achieving anything that even <br />closely approaches ~ moderate premine densities. Additional discussions of woody plant <br />establishment based on reclaimed monitoring data for the Seneca II Mine and adjacent native <br />• stands may be found in the 7987 through 1995 Seneca II Revegetauon Monitoring Reports. <br />The specified overall densities, the densities within the concentrated planting areas, and the <br />pattern of plantings will provide areas within the reclaimed blocks where eventual expansion <br />of shrubs may take place. The patterns will benefit wildlife habitat needs and provide cover. <br />In the interim, the herbaceous dominated reclaimed areas .will provide substantial foraging <br />1 <br />benefits for wildlife and livestock and diversify regional habitat. <br />Woody plant density success will•be evaluated on the basis of a performance standard. The. <br />overall woody plant density for the II-W mine reclaimed areas will be 450 stems per acre. In <br />all concentrated planting areas, the woody' plant density standard will be 2,000 stems per <br />acre. In the concentrated aspen sites a[ least 500 stems of the 2000 stem density standard <br />will be aspen. In the mesic drainage-wetter phase sites along Dry Creek, at least 150 stems <br />per acre as tree species will be included in the 2000 stem density standard. At the permanent <br />pond sites, the 2000 stem density standard will include at ,least 1 50 stems per acre as tree. <br />species. Exhibit 22-1 and 22-1A illustrates the general location of the shrub and the tree <br />planting areas. Shrub and tree establishment areas will be delineated and sampled separately <br />from the general reclaimed units. Random or systematically placed density plots, depending <br />on size of unit, will be used in sampling., Plot size will be 100m2. <br />Woody plant density in the overall reclaimed areas in the II-W South Extension area will be <br />200 stems per acre. In all concentrated shrub and tree planting areas, the woody plant <br />density standard will be 2,000 stems per acre. In the concentrated "aspen sites, at least 500 <br />stems'of the 2,000 stem density standard will be aspen. <br />The woody plant density of the appropriate revegetated area will be considered acceptable if <br />the density is not less than 90 percent of the approved standard in reclaimed lands and <br />concentrated sites with 90 percent statistical confidence. Density shall be determined by the <br />number of countable tree and shrub stems per unit area. ~ Woody plant densities will be <br />measured in a 1 m x 50m' (50m'I or, larger direct count quadrat. All quadrats will be randomly <br />located and sampling intensity will be~to statistical adequacy or a specified maximum sample <br />size determined in consultation with CMLRD. The counted tree or shrub will be alive and -~ <br />healthy and in place at least [wo growing seasons. When counting stems; consideration will <br />• be given to shrubs which spread by above or below ground runners. <br />45 Revised 1 /99 <br />
