Wetland Delineation Report <br /> Stonegate Farm,Orono& Medina, MN <br /> BES Project No. 2015-021 <br /> September 18,2015 <br /> basin. The water table (A2) and saturated soil (A3)were observed at 0 inches in the wetland <br /> soil pit. The other wetland hydrology indicator obsenred in the wetland included inundation <br /> saturation visible on aerial imagery(C9), saturation visible on aerial imagery(C9), geomorphic <br /> position (D2)and a positive FAC-neutral test(D5). The adjacent upland vegetation was <br /> sampled on a slight topographic rise on the east side of the basin. The uplands around the <br /> other half of basin have been disturbed by farm operations. The upland (SB-U) is dominated by <br /> basswood (Tilia americana), sugar maple (Acer saccharum), white oak(Quercus a/ba), common <br /> buckthorn (Rhamnus cathartica), gooseberry current(Ribes cynosbat�) and nannyberry <br /> (Viburnum lentago)with no herbaceous layer. The vegetation community did not meet the <br /> dominance test and had a prevalence index of 3.92. The upland soils consisted of nine inches <br /> of 10YR 2/1 loam over 10YR 4/2 clay loam. Free water and saturated soil was not observed <br /> within a depth of 16 inches in the upland soil. No other wetland hydrology indicators were <br /> observed at the upland sampling point. The wetland boundary was generally staked along the <br /> vegetation transition and topographic break. <br /> Wetlands D and E <br /> These two wetlands are smatl depressions in the woods along the northeast edge of the site. <br /> These wetlands have a closed overstory canopy which limits the emergent vegetation in the <br /> basin. Wetland C,just to the south is larger and has an open canopy with cattails and reed <br /> canary grass in the basin. Wetlands D and E are Palustrine, Broad-Leaved, Forested, Seasonal <br /> flooded, (PF01C) hardwood swamps. Sample point SD-W is dominated by silver maple (Acer <br /> saccharinum), green ash (Fraxinus pennsylanica), common buckthorn, reed canary grass lake <br /> sedge (Carex/acustris) and jewelweed (Impatiens capensis). The vegetation community met <br /> the dominance test and had a prevalence index of 1.90. Soils in the wetland consisted of five <br /> inches of N 2/0 clay loam, over 15 inches of N 2/0 clay, over 10YR 4/1 clay(Al2). Surface <br /> water up to eight inches deep was present in the basin at the time of the site visit. The water <br /> table (A2)was at seven inches and saturated soil (A3)was observed within a depth of three <br /> inches in the wetland soil pit. The other wetland hydrology indicator observed in the wetland <br /> included; inundation visible on aerial imagery(B7), geomorphic position (D2) and a positive <br /> FAC-neutral test(D5). The adjacent upland (SD-U) is dominated by sugar maple, common <br /> buckthorn, nannyberry, white snakeroot(Ageratina a/tissima), Virginia creeper(Parthenocissus <br /> quinquefolia),jack-in-the-pulpit(Arisaema triphyllum), fragrant bedstraw(Galium triflorum) and <br /> northern wood violet(Vio/a papilionacea). The vegetation community did not meet the <br /> dominance test and had a prevalence index of 3.74. The upland soils consisted of 8 inches of N <br /> 2/0 clay loam, over ten inches of 10YR 3/1 clay, over 10YR 4/1 clay. The water table was <br /> observed at 14 inches and saturated soil (A3)was at a depth of 12 inches in the upland soil pit. <br /> No other wetland hydrology indicators including the FAC-neutral test were observed at the <br /> upland sampling point. The wetland boundary was generally staked along the vegetation <br /> transition and topographic break. <br /> 4 <br />
