Wetlands are those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to maintain saturated conditions. These can be either preexisting natural wetlands (e.g. marshes, swamps, bogs, cypress domes and strands, etc.) or constructed wetland systems.[r]
