For reclaimed pastureland, cover and production will be compared to cover and production on the pastureland <br />reference area. For rangeland, a weighted average will be generated for cover and production for all the <br />• reclaimed sites in the affected area and for all the corresponding reference areas. Both a weighted average and a <br />pooled variance will be computed using the Wyoming Departrnent of Environmental Quality, Land Quality <br />Division, Guideline No. 2, March 1979 revision. <br />Production data of both rangeland and pastureland and the respective reference areas will be collected by <br />clipping life fotms and the single species Medicago saliva (alfalfa). The various life forms will be clipped, oven <br />dried, and weighed to the nearest 0.1 gram. The life form categories include shrub, sub-shrub, perennial grass, <br />annual grass, perennial forb, annual forb, and undesirable perennial forb. <br />The approved shrub density standard for rangeland is 1,000 stems per acre (see State Program submission date <br />June 4, 1982 accepted August 4, 1982). The species diversity standard for rangeland states that at least 4 species <br />will make up 64% of the relative percent composition in the reclaimed plant community and no single species <br />will contribute more than 40% of the relative composition (see State Program submission dated December 17, <br />1984 and Midterm Review February 3, 1984). The species diversity standard states that alfalfa shall not exceed <br />75 percent relative production, and perennial grasses shall provide at least 25 percent relative production. Also, <br />no single species shall exceed 75 percent relative cover. <br />Annual reclamation reports will be submitted by March IS each year. During the liability period, CYCC will <br />obtain cover, production, and woody plant density data on areas which have been revegetated for three (3) years. <br />The parameter of cover will be assessed using an inclined ten-point frame. Production will be detetmined by <br />clipping three (3) randomly placed plots per transect. Samples will be oven dried, weighed to the nearest 0.1 <br />gram, and plot values will be averaged for each transect. Woody plant density will be determined by counting <br />• individual woody plants rooted within 2 x 50 meter transects. Data relative to soil conditions (soil surface <br />factors), along with 3 yeaz old vegetation data, will be submitted periodically. <br />• <br />MR 95-83 780-136-3 Revised 12/15/95 <br />
