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.
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.

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.
The result is a large number of wetland classification systems that each define wetlands and wetland types in their own way. [1] However, many classification systems include four broad categories that most wetlands fall into: marsh , swamp, bog , and fen. [ 1 ]
A freshwater swamp forest is a type of wetland ecosystem characterized by its unique hydrology and vegetation. These forests are typically found in low-lying areas, riverbanks, and floodplains where there is a consistent supply of freshwater. [3]
The wetland receives most of its water and nutrients from precipitation (ombrotrophic) rather than surface or groundwater (minerotrophic). The wetland is nutrient-poor (oligotrophic). The wetland is strongly acidic (bogs near coastal areas may be less acidic due to sea spray). Because all bogs have peat, they are a type of peatland.
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]
