Australia has had the biggest number of animal extinctions in the world in the past 200 years, eight of those have been marsupials from the Victorian Volcanic Plains. Changes in habitat and the introduction of sheep, foxes, cats and rabbits have decimated populations of marsupials. The loss of these soft footed animals has impacted on the native flora. Their foraging, digging and excretion patterns have effected the health and existence of the plants.
