14 <br />VEGETATION <br />' The Colorado Mined Land Reclamation Board (September 5, 1979) directed <br />Macar Corporation to develop a vegetation map, with specific emphasis on the <br />' disturbed areas and utilizing the natural vegetation as :sources of control <br />plots. Cover, productivity, density and diversity are to be considered. A <br />' species list is to be developed. Considering fLture reclamation, emphasis <br />' is to be given natural invasions of disturbed areas, such as the walls of <br />the benches. <br />' Because of the lateness of the biological. year, not al] of the directions <br />could be carried to completion. Four transects were estab]ished between the <br />mine adit and the extent of the surface of the previous working,;; (1600 feet). <br />' Permanent plots were established at 125 meter intervals along each transect. <br />One transect was established below the mine benches, immediately below the <br />' retention pond. Specimens were collected wherever they could be found; <br />most vegetation was dry and crisp, in many cases beyond recognition. Shrubs <br />' and trees were evaluated and community typing was accomplished with ground <br />' observations and aerial photos. <br />Table 5 represents a tentative species list. Three distinctive <br />' communities are recognized at this time: Aspen Community, Sage Community, <br />Field Community. A Spruce-Fir Community is recognized off the study area. <br />' Table ( provides frequency, density, cover and height for the tree and shrub <br />element of the communities. Figure 3 is the tentative vegetation map of <br />the area. Table 7 relates tree size data. Eight photos are provided <br />' (Appendix I) which illustrate the vegetation types (Photos 3, ~+, 8). <br />Photo 5 pictures the existing retention pond. Photo 6 demonstrates some of <br />' the seasonal water retention. Photos 2 :uid 7 chow some of the existing <br />disturbance. <br />1 <br />
