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 freshwater marsh is a non-forested marsh wetland that contains shallow fresh water, and is continuously or frequently flooded. [1] [2] Freshwater marshes primarily consist of sedges, grasses, and emergent plants.
Ranging greatly in size and geographic location, freshwater marshes make up North America's most common form of wetland. They are also the most diverse of the three types of marsh. Some examples of freshwater marsh types in North America are:
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]
There are three basic types of freshwater ecosystems: lentic (slow moving water, including pools, ponds, and lakess), lotic (faster moving streams, for example creeks and rivers) and wetlands (semi-aquatic areas where the soil is saturated or inundated for at least part of the time).
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 freshwater swamp in Florida, United States. A swamp is a forested wetland. [1] Swamps are considered to be transition zones because both land and water play a role in creating this environment. [2] Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater.
