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]
Schoenoplectus acutus (syn. Scirpus acutus, Schoenoplectus lacustris, Scirpus lacustris subsp. acutus), called tule / ˈ t uː l iː /, common tule, hardstem tule, tule rush, hardstem bulrush, or viscid bulrush, is a giant species of sedge in the plant family Cyperaceae, native to freshwater marshes all over North America.
Aquatic plants have adapted to live in either freshwater or saltwater. Aquatic vascular plants have originated on multiple occasions in different plant families; [5] [9] they can be ferns or angiosperms (including both monocots and dicots).
In the intermediate marsh between the brackish and freshwater marsh levels, other plants include common reed (Phragmites australis), sawgrass (Cladium jamaicense), softstem bulrush (Scirpus validus), and Virginia iris (Iris virginica). [1] This rush provides cover for a number of salt marsh animal species.
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.
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]
The Floridian highlands freshwater marsh is a wetland community found on the Florida peninsula. These are upland marshes occurring in shallow peat-filled valleys, the basins of dried lakes, and the borders of existing lakes. The vegetation mosaic includes a range of mostly herbaceous plant communities, varying based on water depth. Deep water ...
