<br />identification. However, the vegetative keys found in May (1960), Copple and <br />Pase (1978) and Ryerson et. al. (1968) were effectively used as aids to insure <br />correct identification. Taxonomic nomenclature primarily follows that of <br />Harrington (19&4). Due to ease of use, range plant symbols found in Plummer <br />et. al. (1966) were used on all field sheets and in the report tables. This <br />reference was also used as the basis for separation of plant species into life <br />forms to determine herbaceous cover and production values. <br />RESULTS <br />A listing of all plant species encountered in the sample plots is presented on <br />Table 1, Plant Species Encountered in 1990 Vegetation Sampling. This <br />summary documents that twenty grass, twenty five forb, and five shrub species <br />were encountered. The large number of grasses is indicative of the dominance <br />of reclaimed areas with respect to the total acreage sampled and the <br />abundance of grasses on these sites. <br />Vegetative cover characteristics for the Sagebrush Reference Area are <br />presented on Table 2, Sagebrush Reference Area, Vegetative Cover <br />Observations. This summary suggests that the undisturbed vegetation <br />community in the reference area is dominated by shrubby species with relatively <br />limited occurrence and diversity of grass species. Vegetative cover <br />characteristics for the reclaimed areas at the Grassy Creek Mine are <br />summarized as follows; <br />• Pit 1: Table 3, Pit 1 Vegetative Cover Observations <br />• Pit 2: Table 4, Pk 2 Vegetative Cover Observations <br />• Pit 3: Table 5, Pit 3 Vegetative Cover Observations <br />• Pit 5: Table 6, Pit 5 Vegetative Cover Observations <br />• Pit 6: Table 7, Pit 6 Vegetative Cover Observations <br />4 <br />
