Flooded forest. Freshwater swamp forests, or flooded forests, are forests which are inundated with freshwater, either permanently or seasonally. They normally occur along the lower reaches of rivers and around freshwater lakes. Freshwater swamp forests are found in a range of climate zones, from boreal through temperate [1] and subtropical to ...
The Blackwater River passes through a shrub swamp in Canaan Valley, West Virginia, US.. Shrub swamps — also called scrub swamps or buttonbush swamps — are a type of freshwater wetland ecosystem occurring in areas too wet to become swamps ("true" or freshwater swamp forest), but too dry or too shallow to become marshes.
However, from 1998 to 2004 the United States managed a net gain of 191,750 acres (776.0 km 2) of wetlands (mostly freshwater). [2] The past several decades have seen an increasing number of laws and regulations regarding wetlands, their surroundings, and their inhabitants, creating protections through several different outlets.
Intertidal forested wetlands; includes mangrove swamps, nipa swamps, tidal freshwater swamp forests Brackish to saline lagoons and marshes with one or more relatively narrow connections with the sea Freshwater lagoons and marshes in the coastal zone
To do this, the NWI developed a wetland classification system (Cowardin et al. 1979) that is now the official FWS wetland classification system and the Federal standard for wetland classification (adopted by the Federal Geographic Data Committee on July 29, 1996: 61 Federal Register 39465). The NWI also developed techniques for mapping and ...
Wetlands within this category include inland marshes and swamps as well as bogs, fens, pocosins, tundra and floodplains. According to the Cowardin classification system, palustrine wetlands can also be considered the area on the side of a river or a lake, as long as they are covered by vegetation such as trees, shrubs, and emergent plants.

This is a list of freshwater ecoregions as compiled by the World Wildlife Fund (WWF). The freshwater ecoregion system is similar to that for terrestrial ecoregions.The Earth's land surface is divided into eight terrestrial biogeographic realms or ecozones, which contain hundreds of smaller ecoregions.
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.
