Low marsh is a tidal marsh zone located below the Mean Highwater Mark (MHM). Based on elevation, frequency of submersion, soil characteristics, vegetation, microbial community, and other metrics, salt marshes can be divided to into three distinct areas: low marsh, middle marsh/high marsh, and the upland zone.

Marshlands are often noted within wetlands, as seen here in the New Jersey Meadowlands at Lyndhurst, New Jersey, U.S. Marsh in shallow water on a lakeshore. 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 ...
Wetlands exist on every continent, except Antarctica. [3] The water in wetlands is either freshwater, brackish or saltwater. [2] The main types of wetland are defined based on the dominant plants and the source of the water. For example, marshes are wetlands dominated by emergent herbaceous vegetation such as reeds, cattails and sedges.
Wetlands have decreased by as much as 50% since 1900 and in some parts of the world by 90%. [ 19 ] [ 20 ] Inland wetlands, freshwater marshes making up about 20-25% of all freshwater wetlands globally, [ 21 ] have been decreasing approximately 1.2% each year throughout the last century (since 1900).
This is a list of bogs, wetland mires that accumulate peat from dead plant material, usually sphagnum moss. [1] Bogs are sometimes called quagmires (technically all bogs are quagmires while not all quagmires are necessarily bogs) and the soil which composes them is sometimes referred to as muskeg ; alkaline mires are called fens rather than bogs.
It is an important source of food, spawning grounds, and nursery for fishes, besides offering feeding and breeding ground to a variety of water birds. Typical marshy vegetation complexes inhabit like Typha, Phragmites, Eleocharis, Trapa, and Nymphoides species ranging from shallow water to open water aquatic flora. Sustainable exploitation of ...
