The different geographical areas of Kakadu have their own specialised plants. The area called ‘the Stone Country’ has ‘resurrection grasses’ that are able to survive extreme heat, and dry conditions followed by periods of heavy rain. Monsoon forests often develop in the cool moist gorges found in the stone country. The southern hills and basins support several endemic plants that are only found in Kakadu such as "Eucalyptus koolpinensis" near Jarrangbarnmi (Koolpin Gorge). 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.
