Commonly known as the Tasmanian Tiger, the Thylacine (Thylacinus cynocephalus) is one of Australia’s best-known native marsupials. The species was first described in 1808 by Tasmanian naturalist G.P. Harris, as Didelphis cynocephala (‘dog-headed opossum’). Its genus was corrected in 1824 by Temminck to mean ‘dog-headed pouched-dog’. Over the following years the Thylacine evoked alot of attention, and thus in 1917 …
Impact of the Introduced Fox on the Australian Environment
Red foxes (Vulpes vulpes) were deliberately introduced into Australia in the 1855 for sporting purposes. The first breeding pair were released in Victoria in the 1870’s. They spread rapidly. By 1893 foxes had become a nuisance in northeastern Victoria, and by 1917 had reached Western Australia. Their distribution generally followed that of the European Rabbit (Oryctolagus cuniculus). Today the fox …
Our Native Fauna – just who is having it for dinner?
Concerns were raised time and time again of just what impact the release (both prematurely in October 1995, and then officially in October 1996) the Rabbit Calicivirus Disease (RCD) would have on native animals. In inland Australia, dingoes frequently increase their predation on the red kangaroo when rabbit numbers crash under natural conditions. Fears that other predators such as foxes …
Species Classification
According to their Conservation Status As different species face individual problems, determining their conservation status can often be difficult to assess. The degree to which a species is threatened is of critical importance in deciding into which classification a species should belong. This decision-making can be highly subjective, as status may change through alterations in either distribution or abundance. In …
The Rabbit Calicivirus – how successful has it been?
With scientists predicting yet another drought-stricken summer, the release of the rabbit calicivirus disease (RCD) couldn’t have been too soon. With over $115 million of lost production yearly to the wool industry, and a $600 million total cost in export income to the agricultural industry, not to mention the immeasurable environmental damage, the European rabbit in still Australia’s most serious …

Sarcoptic Mange in Wombats
Sarcoptic mange is a disease primarily of wombats caused by a small eight-legged mite, Sarcoptes scabiei. It can also cause mange in koalas, ringtail possums, dogs and foxes. Anecdotal evidence indicates that the mite can be transmitted from dogs and foxes to wombats and vice versa. Wombats afflicted with mange are itchy, develop fur loss, and thickened crusty skin. This …
Toxoplasmosis in Native Wildlife
Toxoplasmosis is a disease caused by a small parasite that is shed in cat faeces. Cats are the definitive host for the parasite, but marsupials are extremely sensitive to infection with the organism. Marsupials usually contract the disease through exposure to cat faeces, feed that has been contaminated by cat faeces, or by eating the flesh of another animal that …
Wild Fire & Injured Wildlife
The capture and handling of all wildlife must be performed as quickly and efficiently as possible, to avoid potential injury or captive myopathy #. All animals should be securely confined when transporting – taping cardboard boxes down, tying the end of pillowcases as well as fastening boxes within the car and leaving windows open for extra ventilation. It is not …
