The hydrophytic plant criterion is met when more � <br /> than 50 percent of the dominant species by the 50120 rule for each stratum(herb, shrub/sapling, tree, and I' <br /> woody vine}were assigned an obligate(OBL)', facuitative wet(FACW), and/or facultative (FAC}wetiand I <br /> status. � <br /> With the 50/20 rule, dominants are generally measured by absolute%cover in each stratum which <br /> individualiy 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 soi!is a soil formed under conditions of saturatian, flooding, or ponding long enough during the ' <br /> growing season to develop anaerobic conditions in the upper part. lf a soil exhibits the indicators of a <br /> hydric soil or is identified as a hydric soil the hydric soil criterion is mek <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 Soi� Indicators for the <br /> Midwest Region were noted as presented in the National Technical Committee for Hydric Soils Field <br /> lndicators 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 soi�series found in the <br /> sampfe area for soil identification purposes. <br /> , Cautions used in applvinq the Field Indicators of Hydric Soils <br /> There are hydric soils with morphofogies 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 indicafors 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(ack 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 ideniified by the indicators. Redoximorphic features are <br /> most likely to occur in soils that cycle between anaerobic{reduced}and aerobic(oxidized)condifians. <br /> Morphological features of hydric soils indicate that saturatian and anaerobic conditions have existed <br /> under either contemporary or former hydrologic regimes. Where soil morphology seems inconsistent with <br /> the iandscape, vegetation, or observable hydrology, it may be necessary to obtain the assistance of an <br /> experienced soil or wetland scientist ta determine whether the soif is hydric. <br /> � OBI,—Obliga(c Wctland,occurs an eslim��ted 99%in�vetlands.
