Quokka smiles mask pain on Rottnest Island Biology Diagrams The Rottnest Island Authority has implemented several measures aimed at protecting quokka populations on Rottnest Island, which is home to over 10% of all known quokka populations worldwide. They also serve as a vital component of the food chain for larger predators such as snakes and birds of prey. Without quokkas, the balance of the The quokka (Setonix brachyurus) is also listed as vulnerable by the IUCN, and although it has a stable population on Rottnest Island, Western Australia, the small surviving metapopulations on the Quick facts about the Quokka. On Rottnest Island the quokkas are so friendly they will regularly approach guests. It is illegal for guests to touch the quokkas though. Occasionally people feed the quokkas human food and this causes them to become malnourished or dehydrated.
Quokkas are herbivores so they eat a variety of plants such as leaves, seeds, and shrub buds, which is available in abundance on Rottnest Island. As a vulnerable species, it is illegal to feed the quokka (or any animal on the island) as any food and water that they haven't collected themselves can be harmful to their health and wellbeing.

The crew named the quokkas' island Ratte nest ("rat's nest"), then promptly sailed away, presumably toward something more inviting. The quokka (Setonix brachyurus) is the only member of the genus Setonix and one of the smallest members of the macropod ("big foot") family, which includes kangaroos and wallabies.

This paper mainly focuses on the extinction dynamics of quokka population and its reduction by red foxes, by qualitative and quantitative analyses of a designed tri-trophic food-chain model composing a prey (quokka), a mesopredator (red fox) and apex predator (dingo). Existence of solution are analysed and shown to be uniformly bounded. Food Habits. On Rottnest Island, Setonix brachyurus comes out at night to forage. Depending on the season, adult male quokkas will eat an average of 32 to 45 grams of dry food each day. The majority of their herbivore diet comprises of plants including succulents, shrubs, forbs, grasses and sedges.
