the parameter values from this years sampling at the reclamation areas with the final <br /> revegetation criteria to be achieved. <br /> Total Vegetation Cover (2019) <br /> Final Total Vegetation Cover Success Criterion: 53.04 % total vegetation cover <br /> 2019 Reclaimed <br /> Areas <br /> Xbar 63.43% <br /> S 8.90% <br /> Number of samples 21 <br /> Number of samples for sample adequacy 3 <br /> Based on the results of the 2019 quantitative sampling, the West Elk Mine reclamation areas <br /> sampled exceeded the final total cover revegetation success criterion of 53.04 percent, <br /> thereby meeting and exceeding the final revegetation success criterion and supporting the <br /> post-mining land use. <br /> Total Herbaceous Production (2019) <br /> Final Total Herbaceous Production Success Criterion: 180.38 g/m2 <br /> 2019 Reclaimed <br /> Areas <br /> Xbar 217.13 g/m2 <br /> S 42.43 g/m2 <br /> Number of samples 22 <br /> Number of samples for sample adequacy 7 <br /> Based on the results of the 2019 quantitative vegetation sampling, the West Elk Mine <br /> reclaimed areas exceeded the final revegetation total herbaceous production success criterion <br /> of 180.38 g/m2, thereby meeting and exceeding the final revegetation success criterion for <br /> total herbaceous production and supporting the post-mining land use. <br /> Species Composition (2019) <br /> The West Elk Mine permit document specifies that to meet the requirements of the final <br /> revegetation success criterion for species composition, species composition on any reclaimed <br /> area shall be such that there are at least three perennial species of which two are cool season <br /> perennial grasses and one is a cool season perennial forb. No one component of the above <br /> three species should comprise greater than 40% relative cover nor less than 3%relative cover <br /> during a given year's quantitative sampling. The following reflects the number of individual <br /> species required by the success standard and the number of individual species encountered in <br /> quantitative sampling this year at the West Elk Mine reclamation areas sampled this year. <br /> Mountain Coal Company,LLC West Elk Mine Page 9 <br /> 2019 Vegetation Report:West Bench,Sylvester Gulch,Shaft Canyon Road,and Saddle Road Reclamation Areas <br />
