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.
A freshwater marsh is a non-forested marsh wetland that contains shallow fresh water, and is continuously or frequently flooded. [ 1 ] [ 2 ] Freshwater marshes primarily consist of sedges, grasses, and emergent plants.
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]
Salt marsh during low tide, mean low tide, high tide and very high tide (spring tide). A coastal salt marsh in Perry, Florida, USA.. A salt marsh, saltmarsh or salting, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides.
As a result of this apparent engineering dilemma, large areas of marsh are being lost to the ocean. Since 1930 water has consumed more than 1,900 square miles (4,900 km 2 ) of the state's land. This loss equates to the disappearance of 25 square miles (65 km 2 ) of wetlands each year, or a football field sized area every 30 minutes.
The marsh drains to the southeast, with channels parallel to the coast, exiting between Circeo and Terracina. Although settlement on the mountain slopes began much earlier, deforestation by the Volsci began in the sixth century BC. The marsh rapidly acquired the alluvial deposits of the Amaseno Fan over the peat, bringing much of it above water.
Tate leaves the marsh and Barkley Cove to attend college at the University of North Carolina at Chapel Hill, where he works in biology and protozoology labs under the guidance of professors.
