Species Diversity <br />The diversity of plant species in each area will be evaluated using data acquired from the 50 meter <br />point-intercept transects. Data from the transects will be analyzed implementing Equation 4 to <br />determine the relative cover of each species detected. <br />~ Relative Cover of Species X = ~ Cover of Species X (4) <br />~ Total Veg. Cover <br />Post-mining success of species diversity will be determined by comparing the relative cover values <br />of the reclaimed area with the values ascertained within the vegetation community reference area. The <br />permit states: Kaiser will establish a reclaimed vegetation community with a minimum of two cool <br />season grasses, two warm season grasses, and two fort species. Additionally, within the post mining <br />vegetation community, no single species will comprise more than 40 percent nor less than three <br />percent of the relative cover. There is no cover requirement for shrub species. <br />Kaiser will submit a Phase III draft report for review of data in the fall of 1998. We welcome all <br />comments from the CDMG. <br />We will call you in June to let you know the exact dates of our sampling. If you have any questions <br />or need additional information on our scope of work, please feel free to contact me at (303) 850- <br />0930. We welcome all comments from the CDMG. <br />Sincerely, <br />11 ~ <br />Ryan Hennin <br />Staff Biologist <br />Enclosure <br />cc Jerry Koblitz - Greystone <br />Mike Keegan -Kaiser Steel <br />
