The word palustrine comes from the Latin word palus or marsh. Wetlands within this category include inland marshes and swamps as well as bogs, fens, tundra and floodplains. Palustrine wetlands are one of five categories of wetlands within the Cowardin classification system. The other categories are: Marine wetlands, exposed to the open ocean
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.
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.
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.

In usage in the Southern United States, a bayou (/ ˈ b aɪ. uː, ˈ b aɪ. oʊ /) [1] is a body of water typically found in a flat, low-lying area. It may refer to an extremely slow-moving stream, river (often with a poorly defined shoreline), marshy lake, wetland, or creek. They typically contain brackish water highly conducive to fish life ...
The wetlands of Louisiana are water-saturated coastal and swamp regions of southern Louisiana, often called "Bayou". The Louisiana coastal zone stretches from the border of Texas to the Mississippi line [ 1 ] and comprises two wetland-dominated ecosystems, the Deltaic Plain of the Mississippi River (unit 1, 2, and 3) and the closely linked ...
The Wetlands Geodatabase and the Wetlands Mapper, as an Internet discovery portal, provide technological tools that allow the integration of large relational databases with spatial information and map-like displays. The information is made available to an array of federal, state, tribal, and local governments and the public.
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
