 These soils are mainly black or dark gray and produce an irregular surface relief known as gilgai consisting of a series of small ridges standing 20–60 cm above circular depressions about 2–7 meters in diameter.The main vegetation types of the Kafue Flats are woodland (Miombo, Mopane, Acacia and Combretum), termitaria grassland, flooded grasslands, permanent swamps and levees and lagoons.The Kafue lechwe ("Kobus leche kafuensis"), an antelope specialised for living in the marshy conditions of the flats, is endemic to the area.
