Indicator status of plant species was taken from the National List of Plant Species That Occur in Wetlands: 1988 Minnesota (U.S. Fisb& Wildlife Service, 1988). in. RESULTS Review of Soils. NWf> mim I I )NR Infomation The National Wetland Inventory Map (NWI) (U.S. Fish & Wildlife Service, 1989, Excelsior Quadrangle), shows one PUBF wetland on tl^ property (Figure 2). The Sott Survey of Hennepin County, Minnesota (USDA, 1974) shows the following soil types on the site: Glencoe silty clay loam (Gc), Dundas sUt loam (Du), Hayden clay team (HcD2), and Nessel loam (NeB) (Figure 3). Glencoe and Dundas are bydric soils characteristic of wetlmrf< in the absence of drainage. The DNR Protected Waters Map, Hennepin County (Minnesota DNR, 1981), does not show any DNR Protected Waters, Wetlands, or Waterways on the property. Lydiard Lake (DNR Protected Water 1S9P) is shown approximately 1000 feet west of the property (Figure 4). Wetland Determinations and DellnearioM Potential wetlands were evaluated in greater detail during field observations. One wetland was identified and delineated on the site (Figure 5). Corresponding data forms are included in /V ^ Appendix A. The following description of the wetland and surrounding upland reflects field U^lj} conditions observed at the time of the delineation, which was typical of earfy winter, with dormant vegetation and no snow cover. A thin layer offrost in the soil surfiu:e did not prevent ^ examination of the soils. At the time ofthe delineation recent precipitation levels had been slightly below normal and ten^)eratures were above normaL Precipitation fisr the year was above ^ normal because of an abnormal^ wet spring. Wetland I was a Type 5 (PUBGx) excavated basin located in the western half of the property. f i The extreme eastern edge ofthe wetland occurred on the adjacent property. Based on a review of historical aerial photographs, the wetland appeared to have been excavated to create open ■ water some time between 1953 and 1957, with the spofl material sidecast on the adjacent iq)lands ,) 9^ surrounding the wetland. Most ofthe wetland consisted ofopen water, which was seasonably low, exposing approximate^ 20-40 firet of pond bottom arotmd the edges of the wetland. ^ Scatteredreedcanary grass, green bulrush, and giant ragweed was observed around the edges of n the basin, and duckweed was on the surfrice of the pond and exposed mud. Soils in the wetland consisted of 18 inches of silt loam sediment which had low chroma matrix colors and distinct iron concentrations over a buried black silt bam A-horizon, which had no iron concentratbns. Water was observed whhin 6 inches of the surfrice in soil pits just beb w the delineated boundary. The adjacent uplands primarily consisted of mowed Kentucky bluegrass lawn, with common buckthorn and green ash trees to the north and southwest. Upland soils just above the wetland boundary consisted of 8 inches of black silt bam whbh had no iron concentratbns over sandy
