Extinction or Endangered: Australia’s own threatened species
The ecosystems of the Earth are delicate and unique, which is why the limits to shared space makes for challenging cohabitation. Documented to date, the extinct animals that once resided within Australia rest at a species count of 23 birds, 78 frogs and 27 mammals. Endangered status is considered for a species if there has been a reduction in population by ninety per cent within a decade, if the population range is severely limited or fragmented, or if the population is under fifty individuals. Australia currently holds 86 animal species that are considered endangered. The trend of species extinction can undergo reversal through education, environmental awareness and respect for animal habitats. Here are some of our critically endangered species:
Tiger/spotted-tail quoll Dasyurus masculatus
Extinction’s furry-tailed inspiration is listed as one of Australia’s most critically endangered marsupials. A carnivorous and highly vocal creature, the tiger quoll (or tiger cat) is known to reside in South Eastern Australia and Tasmania. Its lifestyle is largely nocturnal, during which time they can travel over six kilometres – a great distance considering its size! Living for approximately five years, it is the effects of land clearing, excessive baiting and scattered populations that is diminishing lifespan and causing endangered status.
Christmas Island flying-fox Pteropus melanotus natalis
The flying fox is one of the few species of bats that are active during the day. Roosting in the rainforest trees of northern Queensland, the creature feeds on fruits and blossoms of its habitat. Due to deforestation and excessive encroachment on Queensland’s rainforest environment, the flying-fox is losing its predominant source of food.
Regent honeyeater Xanthomyza phrygia
A luminous bird that inhabits the threatened box-ironbark forests of Victoria and New South Wales. The once lustrous plumage of the honeyeater has curtailed as a result of human invasion on its woodland home. True to its name, it feeds on nectar from eucalypt plants, acting as a pollinator for certain flowering plants. 
Western swamp tortoise Pseudemydura umbrina
A local to our state, the swamp tortoise resides naturally in the Swan Valley. It is a carnivore that eats only small mammals, invertebrates and reptiles. Actively functioning only in Winter and Spring, its aestivator lifestyle is the summer equivalent of hibernation. The Swan Valley has undergone decades of land clearing, urban development and exposure to pesticides and fertilisers, all of which have led to the decline of this swamp dweller.
