ERR Peak Ranch Resource <br /> Aquatic Resource Delineation Report <br /> this community in the central western portion of the survey area. The ditch appears to be man-made, <br /> excavated in uplands, and used in the past for agricultural purposes. The ditch is fragmented by a farm <br /> road without a culvert and no indicators of OHWM or regular flow were observed. See wetland <br /> determination data form DP-U3 in Appendix B and Photo 15 for characteristics of the upland ditch. <br /> Rocky Mountain Alpine-Montane Wet Meadow <br /> This vegetation community occupies a much smaller percentage of uplands within the survey area located <br /> surrounding the western and southern boundaries of Aquatic Resource A. The vegetation community of <br /> uplands surrounding Aquatic Resource A is very similar to Aquatic Resource A dominated by hydrophytic <br /> species such as field meadow-foxtail, baltic rush, Canadian thistle, mountain brome, and slender wild rye <br /> (Elymus trachycaulus). While these areas have a vegetation community dominated by hydrophytes, they <br /> lack any positive indicators for hydric soils and wetland hydrology thus do not meet the parameters for <br /> wetland per USACE technical guidelines and procedures (Environmental Laboratory 1987, USACE 2010). <br /> Additionally,these areas lack a defined bed, back, OHWM or indicators of relatively permanent flow thus <br /> do not meet the criteria for stream channel. Baltic rush (FACW) does not appear to be a good wetland <br /> indicator species in this area as it is growing in both wetlands and uplands throughout the northeast <br /> portion of the survey area, and most other dominant species in uplands dominated by hydrophytes have <br /> an indicator status of FAC, indicating only seasonally moist conditions. Soils throughout uplands in this <br /> community are mostly silt loam textured, dry, and light colored. <br /> The upland habitats across the survey area are dominated by FACW-UPL species with dry, light colored silt <br /> loam soils. Hydric soils and wetland hydrology were not present in the upland habitats across the survey <br /> area. <br /> Refer to Photos 13-18 below for characteristics of these upland habitats. <br /> Yd, <br /> i ` <br /> Photo 13.
