Wetland
A swamp is wetland with more open water surface and deeper water than a marsh. In North America, 'swamp' is used for wetlands dominated by trees and woody bushes rather than grasses and low herbs. This distinction does not necessarily apply in other areas, for instance in Africa where swamps may be dominated by papyrus instead of trees. A swamp may also be described by the dominant plants growing in it. For example: A mangrove swamp or mangal is a salt or brackish water environment dominated by mangrove trees. A paperbark wetland is a fresh or brackish water environment dominated by the Melaleuca tree.
