Quokka Fact: With the ability to climb trees, the quokka is described as a habitat specialist β preferring to inhabit areas that have been burned in the last ten years. On the mainland, quokkas can be found in dense riparian or swamp vegetation thanks to the animalβs relatively high-water requirement but can also be found in shrubland and heath areas. Rottnest Islandβs semi-arid areas are favoured by the quokka, and the Islandβs Limestone heath, woodland, wetland, and settlement areas support the largest known population of this wallaby in the world.
