In ecology, a marsh is a wetland that is dominated by herbaceous plants rather than by woody plants. [1] More in general, the word can be used for any low-lying and seasonally waterlogged terrain. In Europe and in agricultural literature low-lying meadows that require draining and embanked polderlands are also referred to as marshes or marshland.
In the 1980s and 1990s, this marshland was drained by upstream dams and water control structures, down to 10% of the original area. [27] The marshland is located on the intercontinental flyway of migratory birds and is used by two-thirds of West Asia's water fowl. [27] The marsh is currently dominated by an invasive grass, Phragmites australis ...
Marshland is a low-lying and seasonally waterlogged land. Marshland may also refer to: Marshland, 2014 Spanish film; Marshlands, Queensland; Marshland, New Zealand
A tidal marsh (also known as a type of "tidal wetland") is a marsh found along rivers, coasts and estuaries which floods and drains by the tidal movement of the adjacent estuary, sea or ocean. [1]
The Marais Poitevin (pronounced [maʁɛ pwatvɛ̃]) or Poitevin Marsh is a large area of marshland in the former province of Poitou in western France. It is a remnant of what was the former Gulf of Poitou . The western zone near the sea (about two-thirds of the area) is called the "dry marsh" (or "dried marsh").
A wetland (aerial view) Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards.
Mudflats near Oban on Stewart Island, New Zealand. Tidal flats, along with intertidal salt marshes and mangrove forests, are important ecosystems. [7] They usually support a large population of wildlife, [8] and are a key habitat that allows tens of millions of migratory shorebirds to migrate from breeding sites in the northern hemisphere to non-breeding areas in the southern hemisphere.
The salinity levels in brackish marshes can range from 0.5 ppt to 35 ppt. [2] Marshes are also characterised by low-growing vegetation and bare mud or sand flats. [3] Due to the variations in salinity, brackish marshes create a distinctive ecosystem where plants from either freshwater or saltwater marshes can co-inhabit. [4]
