<br />2.0 h?ethods <br />2.1 Veeetation Type Delineation and b';appin~ <br />The permit area was extensively surveyed during August and <br />September of the 1980 growing season. Veeetation types which could <br />easily and repeatedly be distinguished on the basis df physio- <br />enomic structure and species composition were noted. The measured <br />scale, the permit boundary, reference area locations, and all <br />major vegetation types in the permit and adjacent areas are <br />identified. Veeetation types of the previously disturbed mine <br />entrance were determined on the basis of vegetation found in <br />undisturbed similar topographic areas and noted on the vegetation <br />map (Figure d). <br />2.2 Selection of Reference Areas <br />All areas disturbed by the present mining operations <br />includine mine facilities, mine portals, roads, and refuse <br />areas were surveyed to determine vegetation types disturbed. <br />Future mining plans were also reviewed to determine which <br />vegetation types would be disturbed in the future. <br />Observed similarities of vegetation composition cover and <br />productivity were factors considered in the selection of specific <br />reference area sites. Other factors considered included slope, <br />exposure, elevation, and potential for lone term management <br />without disturbance. <br />2.3 Vascular Plant Inventory <br />Vascular plant specimens were collected in August and <br />September 1980 and identified. Nomenclature follows Weber (1976). <br />Common names have no formal nomenclature rules. however Weber <br />(1976) and Harrington (1964) were consulted in an attempt to <br />apply the most widely used common names. Areas adjacent to <br />existing roads and other disturbed areas were not sampled <br />because of numerous introduced species. <br />Noxious and designated weed species have been noted <br />(Thornton, Harrington and 2imdahl. 1974). Provenance of the <br />vascular plant species is also noted. <br />2.4 Reference Area Sampline Desien <br />Reference areas were randomly sampled by dividing the <br />areas into grids and using a random number table to determine <br />• which erids would be sampled. Cover and shrub height sample <br />locations are the same. <br />~-~ <br />
