Baseline Technical Report <br /> ARCADIS Report for Soils and Biological <br /> Resources, MLE2 Project Area <br /> common forbs include yarrow (Achillea millefolium), larkspur (Delphinium spp.), <br /> meadowrue (Thalictrum fendlen), fringed sage (Artemesia frigida), cinquefoil <br /> (Potentilla ovina), fireweed (Chamerion danie/sii), goldenrod (Solidago multiradiata), <br /> clover(Trifolium sp.), and milk vetch (Astragalus sp.). <br /> 3.2 Open, Conifer-Dominated Woodland <br /> Open, conifer-dominated woodlands account for approximately 54 acres (13 percent <br /> of the entire survey area) and occur in Sections 3, 4, and 6. This vegetation <br /> community consists of an open tree canopy primarily dominated by lodgepole pine. <br /> Other trees, such as juniper (Juniperus spp.), ponderosa pine, Douglas fir, <br /> bristlecone pine (Pinus aristata), and limber pine (Pinus flexilis) are occasionally <br /> present within this community in the survey area. Bearberry (Arctostaphylos uva- <br /> urs►), curl-leaf mountain mahogany (Cercocarpus ledifolius), common juniper, <br /> bitterbrush (Purshia tridentate), wild gooseberry, and bilberry species (Vaccinium <br /> spp.) form an open shrub layer in some stands. The herbaceous layer is generally <br /> moderate in cover (approximately 20 to 50 percent) and is composed of xeric <br /> graminoids, such as Arizona fescue, Idaho fescue (Festuca idahoensis), bluebunch <br /> wheatgrass (Pseudoroegneria spicata), and clover. This vegetation type tends to <br /> occur at the higher elevations within the survey area. <br /> 3.3 Dense, Conifer-Dominated Woodland <br /> Dense, conifer-dominated woodlands account for approximately 80 acres (19 percent <br /> of the entire survey area), occurring in Sections 2 to 6 (most dominant in Sections 4 <br /> and 5). Englemann spruce and subalpine fir dominate the canopy, either mixed or <br /> alone. Lodgepole pine is common in many occurrences and patches of pure <br /> lodgepole pine are not uncommon, as well as patches of mixed conifer/quaking <br /> aspen stands. This community is composed of a mixed stand of trees, ranging from <br /> saplings (1-10 feet [0.3 to 3 meters] in height) to mature trees (approximately 60 feet <br /> [18.3 meters] in height). This community, like all others, appears to be a result of <br /> secondary succession. Common xeric species include common juniper, twinflower <br /> (Linnaea borealis), or holly-grape (Mahonia repens). Mesic understory shrubs may <br /> include species such as serviceberry (Amelanchier a/nifolia), raspberry (Rubus <br /> parviflorus), and willow species (Salix spp). The herbaceous layer is sparse to <br /> moderately dense (5-40 percent cover). Common herbaceous species include <br /> Colorado thistle (Cirsium scariosum), fringed sage (Artemisia frigida), golden banner, <br /> fireweed, clover, wild strawberry (Fragaria virginiana), yarrow, and cinquefoil. <br /> CCV Baseline Soils Biology Resource Report(11-17-11).doc 12 <br />
