Wetland Delineation Report K& L Farm LLC majority of years (Appendixes I &II),which was considered strong evidence for wetland hydrology. Wetlands 1 and 3 showed clear wetland signatures in only two years. However, since these areas showed marginal signatures in two other years,they were still judged to possess the "Saturation Visible on Aerial Imagery" indicator. Wetland Soils The Natural Resource Conservation Service-mapped soils of the wetland are (Figure 3): Soil Drainage class Hydric? Colwood silt loam (Co) Poorly Drained Yes Sable silty clay loam (SaA) Poorly Drained Yes Colwood and Sable soils form on low-lying landforms,particularly old lake beds, stream terraces and depressions within outwash plains.Typical profiles consist of deep,stratified layers of silt loam and silty clay loam. The field-observed wetland soils consisted of black (10 YR 2/1,N 2.5/0) silt loam or silty clay underlain by lighter-colored,low-chroma (10 YR 4/1, 5/1) clay. Soil profiles were not inspected in three wetland sample plots (Plots 5A, 7A& 8A) since standing water was present and the dominant plants were FacW and Obl-rated. These soils were assumed hydric. Of the five wetland sample plots that were evaluated, four (Plots 2A, 3A,4A& 6A) showed the hydric indicator"Thick Dark Surface" (Al2). One (Plot 1A) did not show a hydric indicator but professional judgment was used to assume it was hydric based on the vegetation,hydrology and landscape position indicators. Wisconsin Wetland Inventory The Wisconsin Wetlands Inventory (W.W.I.) identifies tree and emergent(T3/E1K), tree (T3K) and emergent (ElKf)-dominated wetlands whose boundaries closely match the field- delineated boundaries of Wetlands 1, 3 and 5,respectively (Figure 4). It identifies a tree and emergent-dominated wetland close to but not matching the location of Wetland 2.The W.W.I. does not identify a wetland in the area of Wetland 4. Discrepancies between the W.W.I. and field-identified wetland boundaries reflect the greater accuracy of field methods over interpretation of wetland boundaries from aerial photographs,the method used in the W.W.I. Uplands The uplands were the crop fields that comprised the majority of the project area (Figure 2). They also included tree groves and open,grassy areas on the margins of the ditches. Upland Vegetation The upland crop fields had been tilled recently and were largely devoid of vegetation. Judging from crop residue,they supported a healthy corn crop in the previous growing season. Based on this and the absence of wetland hydrology indicators,professional 5 Taylor Conservation LLC
