The hydrophytic plant criterion is met when more <br /> than 50 percent of the dominant species by the 50/20 rule for each stratum(herb, shrub/sapling, tree, and <br /> woody vine)were assigned an obligate(OBL)', facultat ve wet(FACW), and/or facultative(FAC)wetland <br /> status. <br /> With the 50/20 rule, dominants are generally measured by absolute%cover in each stratum which <br /> individually or collectively account for more than 50%of total vegetative cover in the stratum, plus any <br /> other species which itself accounts for at least 20% of the total vegetative cover. <br /> Soils <br /> A hydric soil is a soil formed under conditions of saturation, flooding, or ponding long enough during the <br /> growing season to develop anaerobic conditions in the ipper part. If a soil exhibits the indicators of a <br /> hydric soil or is identified as a hydric soil the hydric soil criterion is met. <br /> The break between hydric and non-hydric soils was determined by excavating soil pits along transects <br /> crossing the wetland/upland eco-tone and evaluating the soil colors, textures, and presence or absence <br /> of redoximorphic indicators (i.e., mottles, gley or oxidized rhizospheres). Hydric Soil Indicators for the <br /> Midwest Region were noted as presented in the National Technical Committee for Hydric Soils Field <br /> Indicators of Hydric Soils in the United States version 7.0(USDA NRCS 2010)if present at each sample <br /> point. Also, upper soil profiles were compared to the mapped or inclusionary soil series found in the <br /> sample area for soil identification purposes. <br /> Cautions used in applying the Field Indicators of Hydric Soils <br /> There are hydric soils with morphologies that are difficult to interpret. These include soils with black, gray, <br /> or red parent material; soils with high pH; soils high or low in content of organic matter; recently <br /> developed hydric soils, and soils high in iron inputs. In some cases we do not currently have indicators to <br /> assist in the identification of hydric soils in these situations. As long as the soil meets the definition of a <br /> hydric soil, the lack of an indicator does not preclude the soil from being hydric. The indicators were <br /> developed mostly to identify the boundary of hydric soil areas and generally work best on the margins. <br /> Not all of the obviously wetter hydric soils will be identified by the indicators. Redoximorphic features are <br /> most likely to occur in soils that cycle between anaerobic(reduced)and aerobic(oxidized)conditions. <br /> Morphological features of hydric soils indicate that saturation and anaerobic conditions have existed <br /> under either contemporary or former hydrologic regimes. Where soil morphology seems inconsistent with <br /> the landscape, vegetation, or observable hydrology, it may be necessary to obtain the assistance of an <br /> experienced soil or wetland scientist to determine whether the soil is hydric. <br /> 'OBL=Obligate Wetland,occurs an estimated 99%in wetlands. FACW=Facultative Wetland,has an estimated <br /> 67%-99%probability of occurrence in wetlands. FAC=Facultative, is equally likely to occur in wetlands and non- <br /> wetlands,340/6-66%probability. FACU=Facultative Upland,occurs in wetlands only occasionally, 1%-23% <br /> probability. UPL=Upland,almost never occurs in wetlands,<1%probability.NI=No Indicator,insufficient <br /> information available to determine an indicator status. Positive or negative sign previously indicated a frequency <br /> toward higher (+)or lower(-)frequency of occurrence with an category. <br /> Wetland Delineation-Mitigation-Permitting-Monitoring-&inking-Functional Analysis-T&E Surveys 3 <br /> Phase I Environmental Assessments-EAW's-Soil ID-Soil Analysis&Delineation-Environmental Referrals <br /> Pond &Lake Weed Control &Fish Stocking-Tree Surveys-Natural Resource Management Plans <br />
