• 1992 report and summarized in Table 8, the mine area qualified fur bond release <br />consideration in 1992 as well. <br />Table 3 shows that no species exceeds the 60% relative cover cutoff value. <br />Eight species contributed greater than 3% relative cover. Six were cool season grasses <br />(Bromopsis inermis, Dacty[is glomerata, Etytrigia intermedia, Lophopyrum elongatum, <br />Pascopyrum smithii, and Poa pratensis), one was a perennial forb (Eucephalus <br />glaucus), and one was the biennial forb Melilotus o~icina[is. Combined, the seven <br />perennial species summed to just over 80% relative cover (83.2%), the maximum <br />allowable value for three species. Any combination of six of the seven qualifying <br />perennial species sums to less than 80% relative cover. Therefore, as in previous <br />years, the cover data indicates that the site has exceeded the species diversity success <br />requirements. <br />• Sample Adequacy Calculations: <br />Between September 3 and 4, all cover transects were sampled. Sample <br />adequacy for those transects was calculated to be 23.1. Therefore, since the number of <br />randomly placed transects sampled (26) exceeds the calculated sample adequacy value, <br />the mine area can be considered to have been adequately sampled for this parameter. <br />Table 6 summarizes the calculation of the cover sample adequacy value. <br />Because of previous difficulties in reaching sample adequacy with less than 130 <br />samples, and because sampling was carried out toward the end of the sampling season, <br />155 samples were collected to ensure that adequacy would be reached between <br />September 5 and 8. The sample adequacy value for the 155 dried samples was 107.3. <br />Calculations for herbaceous production are included in Table 7. <br />n <br />U <br />8 <br />
