• liability period, and the length of time for successional processes to act upon the recLamed <br />community. <br />r1 <br />~J <br />Observations in reclaimed areas indicate these aeeas have the potential to be more representative of <br />the native sagebrush type rather than the mixed brush type. Monitoring data supports these <br />observations to some extent The number of perennial species with relative cover greater than three <br />percent in the sagebrush reference area is eight three forbs, three grasses, and two shrubs (1991 <br />monitoring data). Representative reclaimed area monitoring data from 1991 (Wadge Pasture) shows <br />eight perennial species occur with greater than one percent relative cover. three forbs, foot grasses, <br />and one shrub. Although dues percent relative cover was selected for the sagebrush reference area, a <br />one percent relative cover value for the reclaimed azea is more representative of this community's <br />early successional status. The above comparison represents a general pattern of similarity. A <br />comparison between data for the mountain brush reference azea and the reclaimed azea did not <br />reflect a similar pattern due to the strong influence of that type's woody component and, to a lesser <br />degree, perennial forb component <br />The diversity standazd for the Seneca R Mine is as follows. <br />- Five perennial forbs with greater than 50 percent frequency; one perenttialfo~b will each have <br />greater than 3% relative cover and two perennial forbs will each have relative cover greater than <br />1 percent. These forbs will not have greater than 40 percent relative covet each. <br />- Six perennial grasses with greater than 50 percent frequency; two perennial grasses will each <br />have greater than 1 percent. These grasses will not have greater than 40 percent relative covet <br />each. <br />- Three shrubs with greater than 5 percent frequency; one shrub will have relative cover greater <br />than 1 percent <br />- Combined relative cover of the three forbs and four grasses will not exceed 80 percent <br />NOTE: Frequency is defined as the number of samples in which the speaes was present divided by <br />the total number of samples. <br />I • <br />Additionally, species density, or the total number of spedes per 100 m2 plot, in the reclaimed areas <br />will be greater than or equal to 20.
