The first class was defined using the following soil suborders as indicators of wetland presence, since they are related to hydromorphic processes: Alfisols of Suborders Aqualfs, Entisols Aquents and Fluvents, Inceptisols Aquepts, Mollisols Aquic and Aquolls and Histosols Saprists and polygons corresponding to Mollisols of Suborders Udolls and Ustolls corresponding to subgroup Aquic (Table 2).
