3.2.2 Wetland B <br />Wetland B is located in the north - central area of the project site, along the east - facing slope of the <br />gulch (Figure 8). It is also a ground -water discharge seepage wetland and totals approximately 0.026 <br />acres. The slope of the wetland averages about 40 °. The wetland starts at the point of groundwater <br />discharge at approximately 6,430 ft. AMSL. It drains downhill to approximately 5,990 ft. AMSL, <br />where water movement and soil saturation abruptly ends. The center of the seepage zone is either <br />unvegetated or sparsely vegetated due to water movement. There is one area of flat topography, <br />which has allowed the formation of a permanent pool of water approximately 10 feet in diameter, <br />which was observed to be an important resource for wildlife, including flocks of birds, deer, and <br />mountain lion. One leopard frog was observed in the pool. The bottom third of the wetland extends <br />into a freshly cleared and grubbed area (location shown on Figure 8). Under the "atypical situations" <br />provisions in the delineation methodology, using professional judgment it was presumed that <br />vegetation and soil wetland characteristics would have extended to the bottom extent of seepage <br />flow, had the clearing not occurred. <br />The wetland is best classified as a Palustrine Scrub - Shrub, Broad - Leafed Deciduous, Semi - <br />Permanently Flooded (PSSIF) and Type 6, Shrub Swamp. This wetland is "Semi- Permanently <br />Flooded" rather than Permanently Flooded as with Wetland A because it generally occurs on a much <br />steeper slope, precluding much inundation. Vegetation in the shrub layer consists of red -osier <br />dogwood, sandbar willow (Salix exigua), gray alder (Alnus incana), narrow -leaf cottonwood. The <br />herb layer consists of field horsetail (Equisetum arvense), arctic rush, Canada goldenrod (Solidago <br />canadensis), woolyfruit sedge (Carex lasiocarpa), three -petal bedstraw (Galium trifidum), New <br />England aster (Symphyotrichum novae - angliae), and shore buttercup. Uplands surrounding this <br />wetland contain gambel oak, narrow -leaf cottonwood, Saskatoon serviceberry (Amelanchier <br />alnifolia), wood rose (Rosa woodsii), snowberry, common yarrow (Archillea millefoliccun), and arctic <br />rush. The locations for both wetland and upland vegetation plots are depicted in Figure 8. <br />Soils are gley in color (31N), clay in texture, and meet the Redox Dark Surface hydric soil criteria. <br />The locations of the wetland and corresponding upland soil borings for Wetland B are depicted on <br />Figure 8. <br />3.2.3 Wetland C <br />Wetland C is also a seepage wetland totaling approximately 0.036 acres (Figure 9), located downhill <br />and to the northeast of Wetland B. It is very similar to Wetland B in shape, size, habitat, aspect, and <br />(D1 <br />
