"- <br />Discussions relating to achievable woody plant density levels <br />have been previously held with the Division for the Seneca II <br />and Seneca II-W Mines. These same arguments are presented in <br />Tab 22 of the Yoast PAP. Similar arguments have been raised <br />by other operators in Colorado. These arguments have centered <br />on two regulatory opinions: high woody densities are <br />necessary to return viable wildlife habitat for a variety of <br />wildlife species, and 1000 or more stems per acre can easily <br />be reestablished over extensive areas of reclamation in <br />relatively short time frames. <br />Wildlife will be affected by mining disturbances and some <br />species will be displaced. Yet, the gradual return of these <br />species will pattern on successional processes taking place in <br />the reclaimed plant communities. The evidence at the Seneca <br />II Mine and other northwest mining operations indicate many <br />species of wildlife are attracted to reclaimed areas in the <br />absence of well-developed woody plant communities. Mule deer <br />and elk are common in reclaimed areas year-round and this has <br />had, ironically, a negative impact on woody plant <br />establishment efforts. These big game species are attracted <br />to the herbaceous dominated reclamation because these lands <br />offer what native lands often cannot - an abundance of <br />nutritious forage (many times available even in winter months, <br />as standing hay), earlier green-up than any native areas <br />benefiting gestation/lactation requirements, and improved <br />• foraging access with escape cover nearby. Small mammals are <br />also commonly found in reclamation. Many birds, including <br />mountain bluebirds, blue grouse, kestrels, vesper sparrows, <br />golden eagles, marsh hawks, and various waterfowl can be found <br />using reclaimed areas. The question becomes then, if these <br />reclaimed areas are not adequate for wildlife because of "low" <br />woody plant densities, then why are these and other wildlife <br />species present? It should be expected that wildlife <br />populations will go through the same successional processes as <br />the vegetation communities, resulting in different kinds and <br />numbers of species over time, not necessarily species <br />associated with sub-climax or climax conditions. Please note <br />the CDOW comments faxed to PWCC on February 15, 1995 did not <br />identify any concerns or problems with the proposed woody <br />plant establishment plan or the woody plant density Standards. <br />In the Division's January 20, 1995 adequacy review package for <br />the Yoast PAP, Comment 81 reflects the greatest deterrent to <br />the quick (i.e., by the end of the liability period) <br />establishment of moderate woody plant densities: cover <br />adequate to control erosion (Rule 4.15.1(2)(b)). <br />Corresponding to this is the requirement to meet production <br />and diversity standards. The cover standard for the Seneca <br />II, Seneca II-W, and Yoast Mines will be greater than 50 <br />percent vegetative cover (reflecting reference area values) <br />and comprised of primarily perennial species. The attainment <br />• of the cover goal plus production and diversity requirements <br />severely reduces any opportunity for establishment of even <br />21 <br />
