What defines a wetland?
WetlandLand that (1) has a predominance of hydric soils; (2) is inundated or saturated by surface or groundwater at a fre- quency and duration sufficient to support a prevalence of hydrophytic vegetation typically adapted for life in saturated soil con- ditions; and (3) under normal circumstances does support a …
