proposed minimum percent relative cover value contributed by the four most dominant species <br />should not be less than 48.29 percent. <br />Proposed Maximum Species Diversity Standard <br />The average percent relative composition of the four most dominant species from the ASRA <br />from the 2009 and 2010 vegetation sampling averages 74.71 percent. Application of the 0.15 <br />percent level of "precision" would produce a corresponding maximum value 87.89 percent. This <br />would mean that the proposed maximum percent relative cover value contributed by the four <br />most dominant species cannot exceed 87.89 percent of the total relative cover of the reclaimed <br />site. Since the DRMS has approved a value of 50 percent relative cover for a single species for <br />other mines in operating in Northwest Colorado, KCC proposes the same standard for the Marr <br />Mine as the maximum percent relative composition value which a single species can contribute <br />relative to the 1999 Reclamation. <br />At the Tipple, the average relative percent composition of the three most dominant species from <br />the 2009 and 2010 vegetation sampling averages 56.81 percent. Application of the 0.15 percent <br />level of "precision" would produce a corresponding maximum value 66.84 percent relative cover <br />for the three most dominant species in terms of percent relative cover on this site. This would <br />mean that the proposed maximum percent relative cover contributed by the three most dominant <br />species could not exceed 66.84 percent. <br />Proposed Revised Permit Language <br />The current discussion of species diversity found on Permit page 780-84a, would be replaced <br />with the following language. <br />On the 1999 Reclamation sites at the Marr Mine, the reclaimed plant community must <br />consist of at least five species possessing relative percent cover values of at least three <br />percent or greater. One of the five species must be either a forb or a shrub species. The <br />four dominant species shall not contribute less than 63.50 percent or more than 87.89 <br />percent of the total relative cover and no single plant species shall contribute more than <br />50 percent of the total relative cover found on this site. The calculation of species <br />diversity values can be made using either data collected from either the first or second <br />year of the Phase III vegetation sampling period individually, or by averaging the data <br />from the two monitoring periods into an average percent relative plant cover value. <br />The current discussion of species diversity found on Permit page 780-84b, would be replaced <br />with the following language. <br />At the Kerr Tipple reclamation site, the reclaimed plant community must consist of at <br />least five species possessing relative percent cover values of at least three percent or <br />greater. At least two of the five species must be either forb or shrub species. The three <br />most dominant species must contribute at least 48.29 percent and not more than 66.84 <br />percent of the total relative cover found on this site. The calculation of species diversity <br />values can be made using either data collected from either the first or second year of the <br />Phase III vegetation sampling period individually, or by averaging the data from the two <br />monitoring periods into an average percent relative plant cover value.
