Wetlands are an important environmental feature in most parts of the Northern Territory (NT).
They support a wide diversity of plants and animals, some of which are found nowhere else.
They also provide important ecosystem services, such as absorbing the impacts of floods and improving water quality.
There are many differents sorts of wetlands, including coastal salt marshes, mangrove swamps, freshwater lakes and swamps, floodplains, freshwater ponds, springs, and saline lakes.
Wetlands can be permanent, seasonal or intermittent, and they can be artificial, such as dams or sewerage ponds.
