percent relative cover value for the reclaimed area is nio re representative of this • <br />community's early successional status. The above comparison represents a general <br />pattern of similarity. A comparison between data for the mountain brush reference area <br />and the reclaimed area did not reflect a similar pattern Niue to the strong influence of <br />that type's woody component and, to a lesser degree, pare finial forb component. <br />The diversity standard for the Seneca II Mine is as follows. <br />- Five perennial forbs will each have greater than 50 percent frequency; one perennial <br />forb will have greater than 3 percent relative cover and two perennial forbs will <br />each have relative cover greater than 1 percent. These forbs will not have greater <br />than 40 percent relative cover each. <br />- Six perennial grasses will each have greater than 50 percent frequency; two perennial <br />grasses will each have greater than 3 percent rel•3t five cover and two grasses will <br />each have relative cover greater than 1 percent. These grasses will not have greeter <br />than 40 percent relative cover each. <br />- Three shrubs will each have greater than 5 percent frequency; one shrub will have <br />relative cover greater than 1 percent. • <br />- Combined relative cover of the three forbs and four grasses will not exceed BO <br />percent. <br />NOTE: Frequency is defined as the number of samples in which the species was present <br />dividetl by the total number of samples. <br />Additionally, species density, or the total number of species per 100 m2 plot, in the <br />reclaimed areas will be greater than or equal to 20. Species density data will be <br />collected during cover sampling with the 100 mz plot oriented on the cover transact. <br />A comprehensive species list will he prepared for the reclaimed and reference areas. Both <br />cover end frequency data will be used in discussions on species distribution and evenness. <br />While many perennial species in reclaimed areas have low relative cover values, their <br />corresponding frequency values can be high. The use of cover, frequency, and species <br />density data in association with the diversity stands r~i will allow assessment of the <br />potential for increasing diversity and the capability for succession. <br /> <br />13.38 Revised 04/29/94 <br />
