guadrats; and shrub and tree density was estimated using the point- <br />centered quarter method. <br />In 1982, Dr. C. Wayne Cook conducted sampling in the surface <br />facilities area. Cover was visually estimated within a 1 sq.m <br />plot; production data was obtained by clipping the same plots; and <br />shrub density was determined by counting stems with 9 sq.m plots. <br />In 1983, additional sampling was conducted in the sagebrush <br />community on the surface facilities area and the previously <br />proposed disposal area by Greystone Development Consultants. Cover <br />was ,determined by the line intercep~_ method; production data was <br />obtained by double-sampling 1 sq.m plots; and shrub density was <br />determined by counting stems within the same 1 sq.m plots. <br />3.6.1.3 Revegetation Standard <br />After CMLRD personnel had reviewed the existing data, it was agreed <br />to use a reference area in the sagebrush community in the previous- <br />ly proposed disposal area as the revegetation standard for the <br />entire project (see letters in Appendix 3.6-3). This was decided <br />for a number of reasons, <br />1. The sagebrush community is the dominant native community <br />in the surface facilities area. <br />2. The sagebrush in the previously proposed disposal area is <br />more representative of the natural community than that at <br />the surface facilities area because it hasn't been <br />disturbed by previous mining activities and doesn't <br />exhibit as great a sign of overgrazing. <br />A reference area of approximately three acres was located near the <br />previously proposed disposal area (Figure 3.6-1). Cover and <br />production were adequately sampled both on the previously proposed <br />disposal area and within the reference area. <br />l__J <br />NCEC - Coal Ridge #1 3-63 ABC/1145/900301 <br />
