Non-tidal, non-forested marsh wetland that contains fresh water
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.[3][4] Freshwater marshes are usually found near the mouths of rivers, along lakes, or are present in low lying areas with low drainage like abandoned oxbow lakes.[5][2] Unlike its counterpart the salt marsh, which is regularly flushed with sea water, freshwater marshes receive the majority of their water from surface water.[6]
