<br />~. <br />h1ETHODS <br />Representative areas of each vegetation type occurring on the <br />t4axlvell ~4ine and Allen Kline permit areas ~•,ere selected for the vege- <br />tation inventory. These reference areas reflected the vegetation that <br />had been disturbed by the mining operations or would be disturbed in <br />the future. Each reference area was fenced, with an opening left for <br />animals to enter. There had been no livestock grazing in the area, <br />but deer grazing o-,as evident. Each reference area was of different <br />dimensions. Diagrams of each reference area are presented in Figures <br />1 and 2. <br />Sampling plots were randomly located in each reference area by <br />a random numbers table and 1PI x 1P1 grid system. Production r,as esti- <br />mated within a 0.5 x l.Ohl plot by clipping major species and species <br />categories. The plants were oven-dried and measurements o-,ere conver- <br />ted to oven-dry weight values. Cover 1•,as estimated v,ithin a 20 x 50 cm <br />plot placed in the upper left hand corner of the 0.5 x 1.Ot•1 plgt. <br />Cover was estimated by major species and species categories to 'the <br />I nearest 1°;.
