which is a wetland

A wetland is a land area, generally flat, in which the surface is flooded permanently or intermittently. By regularly covered with water, the soil becomes saturated, being deprived of oxygen and an ecosystem resulting hybrid between purely aquatic and terrestrial.
The wetland biological category includes areas of different geological properties: marshes, swamps, marshes, swamps, bogs, and seashore areas that have periodic flooding by the tidal (mangrove).
