Freshwater marshes are highly productive and therefore can support a large biodiversity of vegetation. Vegetation is a key component in determining the structure of a freshwater marsh. [7] In a freshwater marsh, there are emergent plants, floating plants, floating leaved and submerged. [8] The primary plant in freshwater marshes are emergent ...
Marshes differ depending mainly on their location and salinity. These factors greatly influence the range and scope of animal and plant life that can survive and reproduce in these environments. The three main types of marsh are salt marshes, freshwater tidal marshes, and freshwater marshes. [3]
Wetlands come in different sizes and types. From top left: Upland vs. wetland vs. lacustrine zones; freshwater swamp forest in Bangladesh; peat bogs are freshwater wetlands that develop in areas with standing water and low soil fertility; a freshwater cattail marsh that develops with standing water and high soil fertility.
Wetlands exist on every continent, except Antarctica. [19] The water in wetlands is either freshwater, brackish or saltwater. [18] 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.
Extensive research has been conducted on deltaic tidal freshwater marshes in the Chesapeake Bay, [9] which were formed as a result of historic deforestation and intensive agriculture. [10] Freshwater tidal marshes are highly productive and are home to a variety of organisms. There is a variety of vegetation that can reside in freshwater marshes.
Palustrine wetlands include any inland wetland that contains ocean-derived salts in concentrations of less than 0.5 parts per thousand, and is non-tidal. [1] The word palustrine comes from the Latin word palus or marsh. [2] Wetlands within this category include inland marshes and swamps as well as bogs, fens, pocosins, tundra and floodplains.
