If a soil exhibits the indicators of a <br /> hydric soil or is identified as a hydric soil tfi�e 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 wetfand/upland eco-tone and evaluating the soil colors, textures, and presence or absence <br /> of redoximorphic indicators (i.e., mottles, gley or oxidize�d rhizospheres). Hyciric Soil Indicators for the <br /> Midwest Region were noted as presented in the Nation;�f Technical Cornmittee for Hydric Soils Field <br /> tnd�cators of Hydric 5ops in fhe United Stefes version 7 0(USDA NRCS 2010) if present at each sampfe <br /> point. Also, uppe�soil profiles were compared to the mapped or inclusionary soil series faund in the <br /> sample area fo�soil ident�cation �urposes. <br /> Cautions use�f in applyina the Field Indicators of Hvcfric Soils <br /> There are t�ydric soils with morphologies that are di�ficuit to interpret. These include soils with black, gray, <br /> or red parent mate�ial; soifs with high pH; soils high or luw in content of org�nic rnatter; recently <br /> developed hydric soils, and soils high in i�on inputs. In some cases we do not currentiy h�ve indicatars to <br /> asslst in the identification of hydric sails i� these situaticros. As long as the soil meets tfi�e definition of a <br /> hydhc soil, the ladc of an indicator does noi preclude tha soi3 from being hydric. The indicators were <br /> developed mostly to identffy the boundary of hydric sail areas and generally work best on the margins. <br /> Not all of the abviously wetter hydric soils will be identified by the indicators. Redoxirnorpt�ic featu�es are <br /> most likely to oc�ur in soils that cycle between anaerob c(reduced) and aerobic(oxidized) conditions. <br /> Morphalogical features of hydric soils indicate that saturation and anaerobic conditions have existed <br /> under eitt�er contemporary or forrrter hydrologic regirnes, Where soil morphology seems inconsistent with <br /> the landscape, vegetatian, or observable hydrology, it may be necessary to obtain the assistance of an <br /> experienced soil or wetlanc! scientist to determine whett�er the soil is hydric. <br /> ' OBL=Obligate Wetland, occurs an esti�nated 99% in wetlar.ds.
