 Natural and historical clearings provide grazing for many animals, such as bare-nosed wombats ("Vombatus ursinus") which occur in high quantities on the island and Tasmanian pademelons.Nearly all the island's animals are native to Tasmania although some, including eastern grey kangaroos, red-necked wallabies, and Cape Barren geese, were introduced during the late 1960s and early 1970s.Fallow deer were also introduced to the island and were present primarily in the French's Farm area, but sometimes wandered as far north as the small marsh behind Hopground Beach, just north of Rutherford Beach.
