Kakadu’s Ecosystems and Their Creatures
Wetlands: A Bird and Reptile Haven
The wetlands of Kakadu, including Magela Creek, Mary River and Yellow Water Billabong, are alive with life. These areas, with alluvial soils and hydrological features, are home to freshwater fish like barramundi and many plant species like spike rush and water lilies. During the wet season, the water levels rise, and these areas become vibrant ecosystems.
Woodlands: Mammals and Marsupials
The woodlands and open savannahs are home to agile wallabies, brown bandicoots, and Black Wallaroos. In the understorey, native species like sugar gliders and Short-eared Rock Wallabies live, while the kapok tree provides excellent shelter.
Monsoon Forests and Moist Gorges
Isolated monsoon forest pockets in areas like Koolpin Gorge and moist gorges are refuges for species that live in humid conditions. These areas are often rich in endemic plants and many frog species, including the northern bullfrog and marbled frog, which can be heard singing after annual rainfall.
Rivers and Billabongs: Aquatic Havens
Rivers like the South Alligator and Alligator Rivers and iconic sites like Anbangbang Billabong are vital for aquatic life. These waterways support estuarine crocs (saltwater crocodiles) and many native fish species.
Birdlife: Kakadu’s Birds
Iconic Species: Jabirus, Brolgas and Magpie Geese
Kakadu has over 280 species of birds. Iconic species like jabiru, magpie geese and brolgas can be seen wading in the floodplains or perched in big trees.
Migratory Birds and Seasonal Visitors
The wetlands are a stopover for migratory birds during the wet and dry seasons. Yellow Water Cruises are the best way to see these bird travellers.
Birdwatching in Kakadu
For the best experience, visit during the dry season, when the water levels are low, and the birds congregate around the remaining water sources, such as Yellow Water Billabong.
Reptiles: Kings of the Wetlands
Saltwater Crocodiles: The Top Predators
Saltwater crocodiles (estuarine crocodiles) are one of Kakadu’s most well-known residents. They regulate their body temperature by basking on riverbanks.
Freshwater Crocodiles and Other Reptiles
The park includes freshwater crocodiles, lizards, and many other reptiles. Crocodiles can be safely viewed from designated viewing areas like Cahills Crossing.
Mammals: Nighttime Wanderers and Daytime Foragers
Wallabies, Bandicoots and more
Kakadu’s mammals include nocturnal species like sugar gliders and bandicoots that forage on the ground. Agile Wallabies and Black Wallaroos can be seen in the southern hills.
Rare and Endangered Mammals
The intact landscape provides habitat for species like the Short-eared Rock Wallaby and other rare marsupials that rely on fragile floodplains and patches of monsoon forest.
