Low water level is usually shallow, and it is a lowland wetland belt that fluctuates frequently. Water can stand or move slowly. The wetland's water is more or less neutral or alkaline, and the water in the wetland is acidic. The wetland environment is usually highly oxidized and nutritious, enabling a wide variety of organisms to breed. Compared to wetlands, there are abundant woody plants, wetland plants are mostly herbaceous plants. Reed and Valerian dominate wetland vegetation. Watch salt swamp

Salt wetlands are a class of many wetlands, including freshwater wetlands and brackish wetland wetlands. The tidal swamp is a wetland found along the coast and estuaries, and the characteristics of the flood are determined by the movement of the mouth of the adjacent estuary, the ocean, or the sea (EPA 2006). Non-tide wetlands lack floods caused by tide movements. Fresh water, brackish water, salt water wetland can be distinguished according to flood or non-flood salt concentration.

Like other wetlands, various birds inhabit the tidal wetlands. Birds found in wetlands such as fish, insects and crustacea terns. Ducks and donkeys are waterfowls that rely not on fish, shrimps, crabs but on lawn wetlands. The tidal salt wetlands also support large birds of prey like Osprey. Herbaceous plants, known as Sedges, dominate the freshwater wetland ecosystem of tidal flats. Water includes water rain and papyrus. Wetland papyrus is one of the most important plants in the development of civilization: the papyrus growing in the Delta of the Nile River is dried and processed by ancient Egyptians and used as an initial paper form.

Okavango wetlands are made up of underwater plants such as papyrus, water lily, airbags. Okavango Delta is a paradise for various animal species. Some animals, such as hippos and crocodiles, live directly in and around wetlands. Other animals such as giraffes and elephants use wetlands as freshwater sources in the dry Kalahari desert. Some human activities pose a threat to wetland ecosystems. Development along the American Gulf coast has reduced the habitats of wetlands in Texas, Louisiana, Mississippi, Alabama and Florida. Large scale development in South Florida has reduced the amount of water flowing through Everglades. Wildlife such as Florida Panthers is on the verge of extinction due to habitat reduction
