<br />cover of desired shrubs at maturity in those areas dedicated to enhancement of <br />mule deer wintering range and other associated wildlife habitat. <br />As clarification, it should be noted that neither the Wildlife Mitigation Plan nor <br />the Reclamation Plan actually establishes woody stem density standards. What <br />is proposed is that woody stem density measurements 1) may be used to assess <br />the success of shrub establishment in final reclamation and 2) may also be used <br />as an indirect predictor of mature shrub cover where development of wildlife <br />habitats is emphasized, as follow: <br />• A woody stem density standard would be applied to the shrub <br />component of the plant communities reclaimed with the permanent <br />revegetation seed mixtures. This standard would be defined by panel- <br />specific determinations of shrub densities in predisturbance communities <br />or in nearby undisturbed areas. The minimum number of woody stems <br />required per acre may be adjusted in accordance with the woody species <br />used in reclamation and consistent with specified postmining land use <br />goals (e.g., wildlife habitat mitigation/ requirements, livestock grazing, <br />etc.). Bulk seeding rates or stem stocking rates may also be adjusted, <br />based on project-specific experience, to result in the establishment of <br />appropriate woody stem densities. <br />• Where development of wildlife habitats is emphasized, a woody stem <br />density standard could be used to indirectly predict the success of woody <br />browse establishment, as would eventually be demonstrated by canopy <br />cover success criteria. By determining the average cover provided by <br />individual shrubs of the appropriate species and degree of maturity at the <br />Piceance Site, it will be possible to calculate the stem density that would <br />eventually result in the desired canopy cover. <br />Again, these performance standards would be established on site-specific and <br />postmining land use-specific bases as part of the work plans to be developed for <br />the individual mining panels in consultation among the affected resource <br />agencies and American Soda. <br />d) The issue of disturbance to higher density canopy cover is addressed in <br />the Wildlife Mitigation Plan, specifically as it pertains to mule deer and raptor <br />habitats. As stated in the Wildlife Mitigation Plan, efforts will be made to <br />maintain the integrity of desirable woodlands (i.e., pockets of higher density <br />pinyon-juniper) when laying out roads, pipeline corridors, and well pads within <br />the mining panels. Regarding mule deer, it is thought that minimizing impacts <br />to these pockets will help maintain post-mining winter range utility. For raptors, <br />this practice will reduce, to the extent practicable, modification of potential <br />nesting habitat. Site review protocols are identified in the Wildlife Mitigation <br />113 Applyd~n Alqut~ Ilmp~s <br />Y.nN l:uLtl \d~um Mimnb Yn~ <br />Arm,cY1 yd<LLI' <br />
