• II4TRODUCTION <br />Vegetation baseline studies were initiated in Nay, 1979 at Peabody Coal <br />Canpany's Nucla Mine located approximately 3 miles northeast of Nucla, <br />Nbntrose County, Colorado. The study area encompassed approximately 106 <br />acres at an elevation of 5700 ft. The objectives of the study included: <br />1. Measurement of baseline vegetation conditions and establishing goals <br />for future reclamation efforts. <br />2. Selection of reference (control) plots in accordance with 30CFR <br />816.116 and as partial fulfillment of 30CI•'R 779.19 of the D.O.I. <br />Office of Surface Mining, Reclamation, and Enforcement Surface Coal <br />Mining and Reclamation Operations Permanent Regulatory Proqram. <br />3. Identification and measurement of vegetation or environmental sit- <br />• utations such as areas of high soil selenium or noxious wt~eds (as <br />defiled by the Colorado Noxious Need Control Act) that ought affect <br />the potential success of reclamation practices. <br />4. Identification of any threatened, rare, or endangered plant species <br />as described in 30CFR 816.97 (b) of the D.O.I. Office of Surface Mining, <br />Reclamation and Enforcar;ent Surface Coal Mining and Reclamation Oper- <br />ations Permanent Regulatory Prcx~ram and any other applicable federal <br />or state laws, rules and regulations governing threatened, rare, or <br />endangered plant species. Vegetation parameters measured included <br />production, Dover, frequency, species car~osition, shrub height, tree <br />density, tree dominance (basal area) and vegetation type distribution. <br />This report defines all methodology employed during the course of the study. <br />Results are summarized in tabular form and discussed within the text of the <br />report. A map delineating vegetation types on the study area is provided <br />in Appendix A. Outer listings of all raw and analyzed vegetation data <br />. are presented by vegetation type in Appendix B. A list of vegetation spe- <br />cies encountered during the field study is included in Appendir. C. Appen- <br />dix D contains results of selenium soil analysis. <br /> <br />
