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)', facultative 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 upper 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 Freld <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 applvinq the Field Indicators of Hvdric Soils <br /> There are hydric soils with morphologies that are di�cult 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 /> devefoped 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 saturafion and anaerobic conditions have existed <br /> under either contemporary or former hydrotogic 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 /> � OE31, �Obli�.:ate Weiland,occurs an estimated 99°�o in wetlands.
