Wetland
A coastal (salt)-marsh typically has very salty water, either directly from the ocean or a mixture of salt water and fresh water. Salt-marshes may be associated with estuaries and along waterways between coastal barrier islands and the inner coast. The plants in this kind of marsh can range from reeds in mildly brackish (salty) water to especially hardy salt-grasses (salicornia) on otherwise bare marine mud. Many plants in salt-marshes have evolved to live in such salty conditions with special adaptations. Salt-marshes may be converted to human use as pasture (salting) or for salt production (saltern).
