plants is proposed at fourteen (14) live woody plants per acre. Reclaimed areas will be <br />considered successfully reclaimed to the final revegetation success criterion for woody <br />plant density if the total number of woody plants on the reclaimed area is not less than 90 <br />percent of the woody plant density value of fourteen (14) live woody plants per acre with <br />90 percent statistical confidence with a one-tailed test. <br />6.4 Species Composition <br />Table 8 depicts the relative cover of species at the 1982 dry meadow affected community, <br />the 1982 dry meadow reference area, the 1995 dry meadow reference area, and the HRSA <br />in 1996, 1997, 1998, and 2010. The number and description of eligible (those species <br />contributing between three and 40 percent relative cover, and not including weedy or <br />undesirable species) has varied from a low of one cool season perennial grass and one <br />cool season perennial forb (1998 HRSA) to a high of three cool season perennial grasses <br />and one cool season perennial forb (2010 HRSA). Based on the information in Table 8 <br />the following species composition criterion is proposed. To meet the requirements of the <br />final revegetation success criterion for species composition, species composition on any <br />reclaimed area shall be such that there are at least three perennial species of which two <br />are cool season perennial grasses and one is a cool season perennial forb. No one <br />component of the above three species should comprise greater than 40% relative cover <br />nor less than 3% relative cover, during a given year's quantitative sampling. Vegetation <br />species that may be used in the calculation of species composition may be any plant <br />species not defined as a noxious or prohibited plant species, and may be native or <br />introduced. <br />Mountain Coal Company, LLC Page 13 <br />Historic Record Study Area Vegetation Sampling Report: 2010
