The variety of forms reflects Tasmania’s diversity of habitats and topography, over 10 000 years of island separation, and our Gondwanan origins. Tasmania has a large complement of endemic species ranging from the Tasmanian devil, native hen and mountain skink to the giant velvet worm and burrowing crayfish; all of which are important elements in our national and global biodiversity. The State’s comparatively large tracts of undisturbed land and the absence of exotic predators like the European fox and stoat has meant that many species now extinct or under threat on mainland Australia continue to survive and flourish in relative abundance. For example, the eastern quoll and Tasmanian bettong are now extinct on the mainland while the spotted-tail quoll, eastern barred bandicoot and ground parrot retain a stronghold in this State. Tasmania’s coastline and offshore islands are important breeding sites for many species such as the Pedra Branca skink, New Zealand fur seal, little tern, and internationally recognised albatross species. The range of the New Holland mouse, orange- bellied parrot, forty-spotted pardalote and swift parrot are also coastal and centre around important elements in the landscape like old growth forest or coastal heath. Our marine species like the spotted handfish, Port Davey skate and tiny seastars of the tidal zone are only now being recognised as essential elements of Tasmania’s unique biodiversity. The task of assessing the conservation status of our invertebrate fauna is enormous considering there are an estimated 35 000 non-marine species alone. Approximately one third of all invertebrates known in Tasmania are endemic and some groups such as the stag beetles (Lucanidae), geometrid moths (Lepidoptera) and primitive syncarid crustaceans (Allanaspides) are of immense biological significance because of their ancient origins and evolutionary links. Many of the freshwater snails Hydrobiidae and cave invertebrates like harvestmen Hickmanoxyomma display high local endemicity and occur only in one stream or one cave site. The giant freshwater lobster Astacopsis gouldi occurs only in rivers across northern Tasmania. Having the distinction of being the largest freshwater invertebrate in the world, this creature is threatened by pollution of waterways, loss of stream vegetation, and recreational fishing. Tasmania’s has much to protect in terms of natural heritage. Despite Tasmania’s extensive national park and reserved land system our State is no different to other parts of Australia in having a long list of species declining due to human impact and other threatening activities. Ongoing clearance, degradation and conversion of native vegetation are recognised as major threats to the long-term survival of many of our unique and common animal species. Other impacts such as pollution of waterways, commercial and industrial practices, inappropriate recreational activities, persecution, and even feral and exotic pests which are not confined to map boundaries, collectively threaten our native wildlife. In some cases it is our own lack of knowledge which prevents us from better understanding and managing declining species.

The Tasmanian emu, King Island emu, Macquarie Island rail and Macquarie Island parakeet all became extinct in the early 19th century either from hunting by early settlers or predation by feral pests. The Miena jewel beetle, known only on flowering shrubs in the Central Highlands, has not been collected since the 1920s despite active searching. A story lies behind every one of our most recent extinctions and the mistakes made continue to be repeated. Persecution of the wedge-tailed eagle today is little different to that of the thylacine.
