• METHODS <br />Quantitative Sampling -General: <br />It is proposed as part of this report that the undisturbed Mountain Shrubland - <br />Dry Phase community which is within the permit area and adjacent to the reclaimed <br />mine be accepted as an extended reference area. This proposal is based on the fact that <br />the present five acre reference area and the baseline adjacent area were statistically <br />equivalent and in theory should be interchangeable in terms of their applicability as <br />success criteria. It is believed that the 1980 baseline survey was completed prior to the <br />development of the extended reference area concept and that this explains why such a <br />reference area was not proposed. <br />• <br />In 1980, baseline vegetation data was collected by the Western Resource <br />Development Corporation describing the North Thompson Creek Mine site (see <br />Vegetation InventorX, Snowmass Mines Pitkin Counq~ Colorado). The baseline <br />survey's vegetation map (Drawing No. D-3-16 -Vegetation Map, Snowmass Coal Co., <br />Mine Area) and the approved permit document (page 4-64) identify that the bulk of the <br />disturfied mine area was classified as belonging to the Mountain Shrubland -Dry Phase <br />vegetation community. The Waste Pile, the Number 1 Mine Area, and the Number 3 <br />Mine Area were all included in this vegetation type. (The Number 1 Mine Portal Area <br />was classified as falling within the Riparian Woodland community while the Number 1 <br />Mine New Fan Site was classified as being within the Mountain Shrubland -Wet Phase <br />community). <br />1 <br />2 <br />
