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 fend/en), fringed sage (Artemesia frigida), cinquefoil <br />(Potentilla ovina), fireweed (Chamerion danielsh), 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 />ursi), 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 alnifolia), 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 />
