Freshwater marshes are emerging or floating vegetation found at the edges of lakes, ponds, lagoons, and also in very slow moving watercourses. Vegetation in the freshwater marshes varies from region to region and elevation. Some freshwater marshes can be largely cattail (Typha domingensis) or a mix of cattail, Paspalum grasses, and sedges and bulrushes (Scirpus spp.).
Freshwater marshes in Amazonia are found in old oxbow lakes covered in mats of floating Paspalum grasses. Freshwater marshes are also formed in very slow moving streams, as well as in pools along the courses of large rivers. Some of these freshwater marshes dry out during the dry season but grasses persist in place until the next wet season.
