Freshwater wetlands are unified primarily by the fact that they are all nontidal freshwater systems dominated by grasses, sedges, and other freshwater plants. However, they differ in their geologic origins and their driving hydrologic forces, and they vary in size from small pothole marshes less than a hectare in size to the immense saw grass monocultures of the Florida Everglades. Grasses and sedges such as the tall reeds like cattails and Phragmites, and floating aquatic plants dominate vegetation.
