42.04 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND MINING ACTIVITIES -- <br />MINIMUM REQUIREMENTS FOR INFORMATION ON ENVIRONMENTAL RESOURCES. <br />• 2.04.10 Vegetation Information. (Cont'd,) <br />(4) (Cont'd.) <br />heartleaf arnica, Colorado blue columbine, waxflower pyrola, <br />western yarrow, Barbey larkspur, meadowrue, and pseudomycop- <br />teus. <br />The aspen type is sometimes a successional stage, invading <br />areas that have been burned or logged. In these cases, it is <br />usually replaced over time by a mature spruce-fir type, Aspen <br />may also occasionally invade mountain meadows dominated by <br />Thurber's fescue. The prolific nature of its rootstalks and <br />suckers enables aspen to invade a native grass community. <br />Mixed Shrubs: The mixed shrub brush-type is found mainly on <br />the northeastern and east facing slopes along the west side of <br />Stevens Gulch. This type is made up of a mixture of various <br />shrub species including cliff fendlerbush, Gambel oak, big <br />sagebrush, serviceberry, mountain mahogany, squawapple, snow- <br />berry, and bitterbrush. The cliff fendlerbush and oak are <br />more common on the lower drier slopes. Scattered juniper and <br />a few pinyon are found in the community. <br />• Undeveloped Pasture/Meadow: Undeveloped pastures and meadows <br />are common in the woodlands of the lower mountains and the <br />woodlands of sub-alpine areas. The plant composition of the <br />meadows varies considerably, depending on the moisture content <br />of the soil. Dry meadows are characterized in the lower moun- <br />tains by Arizona fescue, Idaho fescue, mountain mutely, june- <br />grass, pine dropseed, western yarrow, Fremont geranium, and <br />harebell. In sub-alpine areas, they consist of Tnurber's fes- <br />cue, needlegrass, rough bentgrass, alpine timothy, spike tri- <br />setum, orange sneezeweed, and cinquefoil. Wet meadows consist <br />of tufted hairgrass, blue joint reedgrass, buttercups, marsh <br />marigolds, shrubby cinquefoil, and a variety of sedges and <br />rushes. <br />Oak Brush: The oak brush type occurs at higher elevations <br />above the Orchard Valley Mine site and surrounding the OVWM <br />site. The major species is Gambel oak which occurs in thick <br />stands with widely scattered pinyon and junipers. The under- <br />story consists of low density grasses, forbs, and shrubs. A <br />transition exists between this and the lok~er types with <br />patches and stringers of both pinyon-juniper and mixed shrubs <br />intermingled with the oak brush, depending on the site. <br />Revised 08/01/84 <br />• Revised 10/12/86 <br />Revised 10/01/87 <br />72 <br />
