This article is about marsh, a type of wetland. For other uses of the word marsh see Marsh (disambiguation).
Atlantic coastal salt marsh in Connecticut.
In geography, a marsh is a type of wetland, featuring grasses, rushes, reeds, typhas, sedges, and other herbaceous plants (possibly with low-growing woody plants) in a context of shallow water. A marsh is different from a swamp, which is dominated by trees rather than grasses and low herbs. The water of a marsh can be fresh, brackish, or saline. Coastal marshes may be associated with estuaries and along waterways between coastal barrier islands and the inner coast.
Marshes are critically important wildlife habitat, often serving as breeding grounds for a wide variety of animal life.
However, while the marshlands have long been viewed as a problem area, Clark pointed out that it was not until after the Marsh Arabs participated in a rebellion against Saddam Hussein immediately after the Persian Gulf War that redeveloping the marshlands began in earnest.
Building upon Clark's history of the marshlands and the Ma'dan, Brasington presented an overview of the geography and ecology of the marshlands.
The destruction of the marshlands also has produced a significant humanitarian problem as there are currently more than 100,000 Ma'dan refugees who have fled to Iran and an estimated 500,000 Marsh Arabs refugees scattered around the globe overall.
