Australian endangered animals
In the past 200 years about 17 different Australian mammals have become extinct. Many more mammals and other animals are in danger of dying out. Australia has moreendangered species than any other continent.

Animals such as cattle and sheep often crush the burrows of small native animals.
Loss of habitat is also another major cause of the reduction of native animalnumbers.

The last known thylacine died inHobart Zoo on 7th September 1936. This day is now known as Threatened Species Day.

The has not been sighted since the 1960s, and is probably extinct. Its relative, the Greater Bilby is now endangered.Once common in central Australian desert areas, the numbers have been reduced by fire and foxes and its habitat affected by grazing cattle and rabbits.

The numbat is endangered because of habitatloss and foxes. Once common across the southern part of the continent, it is now only found in a few forests in southwest Western Australia.

Leadbeater's possum was not seen after 1909 and wasthought to be extinct, but the possums were found again in 1961. They are endangered, and are only found in the Victorian central highlands, in old forest areas that are being logged. The animals nest in...
