 Lowland areas form a large proportion of Kakadu National Park and are mainly covered in eucalypt-dominated open woodland with the ground layer consisting of a large range of grasses including spear grass, sedges and wildflowers.The Kakadu plum, "Terminalia ferdinandiana", is commonly found in the area.The floodplains, which are inundated for several months each year, feature sedges such as spike rush as well patches of freshwater mangroves (itchy tree), pandanus and paper bark trees (Melaleuca).
