Exhibit -,T <br />Vegetation Information <br />Section 6.4.10 <br />Gold Basin Mine, Inc. <br />Gold Basin Mine- Chaffee County <br />Granite, Colorado <br />Colorado Division of Reclamation Mining and Safety <br />112 Permit Application <br />The montane- subalpine grassland system occurs in 1% of the County at elevations above 8,000 <br />ft. An occurrence usually consists of a mosaic of two or three plant associations with one of the <br />following dominant hunch grasses: Danthonia spp., Peslucu spp., or "uhlenbergia filiculmis. <br />The sub-dominants include Muhlenhergia montana, Bouteloua grucilis, and Poa secunda. Foils <br />resemble prairie soils in that the A- horizon is dark brown, relatively high in organic matter, <br />slightly acid, and usually well - drained (Turner 1975). Frequent fires help to maintain the <br />grassland dominants and may play an important role in restricting the invasion of trees and <br />shrubs (Turner 1975). These large patch grasslands are intermixed with matrix stands of spruce <br />fir, lodgepole, ponderosa pine, and aspen forests. <br />Floristic composition varies with site characteristics and grazing history (Turner 1975). Forbs <br />tend to be more prominent at higher elevations, and shrubs at lower elevations (Turner 1975). <br />Forbs are characteristically absent from bunch grass dominated grasslands with a long history of <br />heavy sheep use (Turner 1975). <br />Undisturbed Shrubby Alpine Range Sites- Vegetation Density 95% -Mange Conditions are <br />considered excellent <br />The Cache Creek site is located at the base of Quail Mountain. Grasses and grass -like species <br />include Kobresia, spike trisetum, Poa Spp Tufted hairgrass„ Carex spp, Alpine Clover -dwarf <br />closer trifolium spp. <br />CO qt <br />6 Survey of Critical Biological Resources, Chaffee County, Colorado, 2009, Colorado State University prepared for ro <br />Chaffee County and EPA Region Vill prepared by CSU- Colorado Natural Heritage Program 9 <br />December 28, 2014 <br />Colorado Division of Reclamation Mining and Safety <br />Gold Basin Mine, Inc. <br />Gold Basin Mine <br />Granite, Colorado <br />
