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.

Pistia, a genus with one species that is native to tropical environments and has further extended its range as an introduced species. Phragmites is a genus of plants known as reeds. Pondweeds are a family of aquatic plant with a subcosmopolitan distribution. Sagittaria is a genus of plants known as arrowhead or katniss.
There are three basic types of freshwater ecosystems: Lentic (slow moving water, including pools, ponds, and lakes), lotic (faster moving water, for example streams and rivers) and wetlands (areas where the soil is saturated or inundated for at least part of the time). [9] [8] Freshwater ecosystems contain 41% of the world's known fish species ...
White water lilies are a typical marsh plant in European areas of deeper water. Many kinds of birds nest in marshes; this one is a yellow-headed blackbird.. Marshes provide a habitat for many species of plants, animals, and insects that have adapted to living in flooded conditions or other environments. [1]
Wetlands are not only freshwater habitats and systems, as there are salt marshes and bogs that support different species. [ 7 ] Carolina Bays (also known as pocosins, meaning "swamp on a hill") are a unique form of wetland predominately found in the Carolinas, with a few being found outside of the Carolinas along the East Coast of the United ...
A general definition provided by the textbook Wetlands describes a fen as "a peat-accumulating wetland that receives some drainage from surrounding mineral soil and usually supports marsh like vegetation." [8] Three examples are presented below to illustrate more specific definitions for the term fen.
A wet meadow is a type of wetland with soils that are saturated for part or all of the growing season which prevents the growth of trees and brush. Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. [1] Wet prairies and wet savannas are hydrologically similar.
