Wetland Delineation Report K& L Farm LLC <br /> judgment was used to assume the upland crop fields would support dominance by upland <br /> vegetation under normal circumstances,i.e. cessation of tillage. <br /> Small areas of natural vegetation were noted on the uplands along the ditch banks and in a <br /> line of trees near Wetland 5 (Figure 2). These areas supported a grassy ground layer,except <br /> where heavily shaded,of brome grass (Bromus inermis-Upl) and reed canary grass and shrub <br /> and tree layers of gooseberry (Ribes missouriense-Upl),honeysuckle (Lonicera X bella-FacU), <br /> buckthorn and box elder. <br /> The banks of the north-south ditch (Plots 7A&7B) had been cleared of brush and trees <br /> recently. <br /> Upland Hydrology <br /> No hydrology indicators were noted in any of the upland sample plots.All parts of the <br /> uplands were moderately to well-elevated above the wetlands. <br /> Analysis of air photos for 7 normal precipitation years (1994, 1995, 1997,2002,2003,2004 <br /> &2005,Appendixes I &II) did not show evidence of wetland hydrology in the majority of <br /> years in any part of the upland portions of the crop fields. <br /> Upland Soils <br /> The Natural Resource Conservation Service-mapped soils of the uplands are (Figure 3): <br /> Soil Drainage class Hydric? <br /> Colwood silt loam <br /> (Co) Poorly Drained Yes <br /> Sable silty clay <br /> loam (SaA) Poorly Drained Yes <br /> Virgil silt loam Somewhat Partially <br /> (VrB) Poorly Drained Hydric <br /> Virgil soil forms in low-lying areas on glacial landforms.Typical profiles consist of silt loam <br /> surface layers underlain by silty clay loam subsoil,which is in turn underlain by glacial till or <br /> outwash parent material—usually sandy loam or sand and gravel. <br /> The field-observed upland soils showed the same colors and textures as the wetland soils.All <br /> upland sample plots showed hydric soil indicators ["Redox Dark Surface" (F6) and/or <br /> "Thick Dark Surface" (Al2)]. Since the entire project area is mapped as hydric or partially <br /> hydric soils (Figure 3),it is possible the project area was all once wetland until construction <br /> of ditches drained most of the site. The absence of hydrology indicators and evidence of <br /> recent healthy crops suggest the hydric indicators are relicts of a wetter period rather than <br /> indicators of current conditions. <br /> 6 Taylor Conservation LLC <br />
