<br /> <br />Regional Vegetation: <br /> <br />EXHIBIT J - Vegetation <br />The Schwartzwalder Mine site is located in a valley in the <br />foothills of the Colorado Front Range. Area topography consists <br />of steep hillsides (5-40% grades), mountain top ridges, occa~>ional <br />rocky outcrops, and Ralston Creek lining the bottom of the v~~lley. <br />The site is located in a (generally) northwesterly-southwesterly <br />directed canyon. Elevation ranges from about 6500 ft. to about <br />7290 ft. in the project site. <br />The vegetation of the study area, geographically defined as the <br /> <br />• <br />SE1/4 of Section 25, is a mozaic of several types. Dense riE~arian <br />forest vegetation borders Ralston Creek. The northeast-facing <br />slopes and gullies are dominated by Douglas-fir trees, while the <br />southwest- and west-facing portions of slopes are dominated <br />by Ponderosa pine. Mountain mahogany stands cover south-, exist- and <br />southwest-facing slopes. Grassland vegetation predominates on most <br />of the area and is found on all slopes, especially those witF~ a less <br />steep grade. Draws and gulches are lined with moisture-loving species <br />from the other vegetation stands. (For the purposes of this report, <br />vegetation in such draws were combined with results for the F~rincipal <br />stand types). An ill-defined sixth type of vegetation is confined <br />to disturbed areas along roads. This ruderal vegetation is comprised <br />of a variety of weedy plant species, some introduced to the area and <br />with several native weedy types predominating the roadsides. <br />(1967) for major ecosystems of the east slope of the Coloradc Front <br />The vegetation stand-types are similar to those described by Marr <br />Range. Generally, the Schwartzwalder site is located in a transition <br />J-1 <br />
