• Section 5.4.2 of this Project Description, the procedure proposed for stripping of soil will <br />attempt to salvage suitable soil when the thickness appears to exceed six inches over a <br />sufficiently large area (>I acre). Buried soils, such as are found in disturbed areas, <br />generally are not salvaged. Site-specific conditions. may, at times, justify salvage of <br />weathered parent material. Projected soil volumes to be salvaged and available for use in <br />reclamation can be found in Reclamation and Closure, Section 11.0. <br />4.9 Vegetation <br />The vegetation information for the project site is based primarily on vegetation mapping <br />conducted by Greystone Environmental Consultants in the late summer and early fall of <br />1999. It also is based on previous vegetation mapping and data compilation by JBR <br />Environmental Consultants and CC&V in support of Amendment No. 7. Arcadis <br />biologists visited the project site in June 2007 to verify mapped vegetation types within <br />the proposed MLE area. The site visit confirmed vegetation types previously mapped. A <br />complete discussion of site vegetation and the Arcadis survey results are provided in the <br />Arcadis Baseline Technical Report for Soils and Biological Resources found in Appendix <br />3, Volume III of this document. A map of the vegetation areas can be found as Drawing <br />3-1 in Appendix 2. <br />• The previous information identified six vegetative communities within the permit <br />boundary: grassland/mountain meadow communities, mixed conifer communities, aspen <br />stand communities, riparian/wet meadow communities, disturbed areas, and reclaimed <br />areas. The more recent work subdivides several of the large units shown on previous <br />vegetation maps. Vegetation units identified include aspen-dominated woodlands; <br />brush/montane scrub; open, conifer-dominated woodlands; dense, conifer-dominated <br />woodlands; natural grasslands; disturbed grasslands; riparian woodlands; wet meadows; <br />disturbed areas; and reclaimed areas. <br />As noted in the discussion of soils, much of the District is disturbed by historic and <br />current mine-related activities (e.g., underground mine rock dumps, prospect pits, surface <br />mines, overburden storage areas, roads). The site lacks dense vegetative cover in most of <br />these areas. The vegetation in the undisturbed areas is more mature and serves to best <br />characterize the vegetative communities. Several major vegetation communities were <br />identified in the 1999 survey. These include a well-developed natural grasslands <br />community in undisturbed areas. This community shows variations in species dominance <br />according to slope and aspect. In addition, grasslands are found as re-established on <br />• historically disturbed areas, but the composition, density, and cover of vegetation is <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension <br />4-19
