VEGETATION INFORMATION - EXHIBIT J <br />1. Site Description and Land Use Information <br />Existing Conditions <br />The following resources were used in identifying vegetation on site: <br />- Soil Conservation Service (SCS). 1977. Range Site Description for Dry Mountain <br />Outwash ( Code 316). <br />- Soil Conservation Service (SCS). 1976. Range Site Description for Mountain Outwash <br />(Code 311). <br />- Soil Conservation Service (SCS) 1979. Land Use and Natural Plant Communities, Park <br />County, Colorado (Map and Technical Guide Documents) . <br />The site consists of three distinct vegetation communities which are easily seen in the aerial image <br />of Map C -1. These are: <br />1) Forest habitat type along the poorer soils along the bank of the Middle Fork of the South Platte River. <br />The dominant conifer overstory (approximately 30 -40 percent) consists of Lodgepole pine (Pinus <br />contorta), some Spruce, and some aspen. The herbaceous understory layer consists mainly of <br />Kinnikinnick (Arctostaphylos uva -ursi) with mixed grasses and forbs. These are primarily Arizona <br />fescue, Mountain muhly and Spike fescue. This area coincides with Soil Map unit FA (Forested <br />association with varying slopes). Most of this area will remain undisturbed. <br />2) The subalpine meadow in the relatively flat soils of the Map Unit UF, which exhibits primarily <br />Arizona and Idaho fescues and funged sagebrush, with poa and muhly as subspecies. Indian ricegrass, <br />and muttongrass. Other grasses not forming a major portion of the graminoid community are Idaho <br />fescue (Festuca idahoensis), Spike fescue (Leucopoa kingii), and Junegrass (koeleria cristata). Shrubs <br />also present were Mountain sagebrush (Artemisia Frigida), currant and shrubbry cinque -foil (Dateatilla <br />fructicosa). In open and undisturbed parks, Pasture sagebrush (Artemisia frigida) is the dominant shrub. <br />3) Previously disturbed areas have very gravelly and cobbly material on the surface which provides little <br />opportunity for natural revegetation. This area coincides with Soil Map unit MS (Mine soils), have very <br />sparse vegetation cover but what grasses do occur are Foxtail barley, Bottlebrush squirreltail, and Blue <br />wild -rye. These soils usually exhibit stands of rabbitbrush as well, in the areas that have been drastically <br />disturbed, but still have an adequate plant - growth medium. <br />Sullivan Aggregate Pit March 2015 J -1 <br />
