 EVOLUTION
 
The fauna of Tasmania is very ancient in its origins, and due to this island's geographic isolation is  unique and in many cases rare. Tasmania has been separated for 10,000 yrs from the Australian mainland since the end of the last Ice Age. This has meant a quite different evolution from Australia has taken place since then, in both flora and fauna. The ancient origins are from the super continent of Gondwanaland  - an amalgam of Africa, Australia, Antarctica, India, South America and Australia during the Late Cambrian period - 570 million years ago. . Australia is the stronghold of Marsupials (Mammals that carry their young in pouches after birth) In the case of Tasmania this is exclusively bar to egg-laying marsupials - Echidna and Platypus..  Several icons of Australian wildlife are not present namely the Koala Bear, the Dingo and the Emu. Conversely several Tasmanian icon species are no longer present either in Australia namely the Tasmanian Devil, the Tasmanian Tiger and a good number of other species. The factors for this are largely climatic, but also heavily influenced by man both Aboriginal and European. As Tasmania emerged from the last ice age it had been heavily glaciated in parts and other than a few  remnant areas of alpine vegetation it was predominantly arid cold  Steppes. Wildlife crossed the landbrige to Australia, but due to the severely cold and arid climate this restricted the movement of many species especially the Koala. Except in the cases of the suspected extinction of the Tasmanian Tiger (last recognized one dying in the 40's)  and the Tasmanian Emu this island has be more fortunate than Australia where many species have totally disappeared. The Europeans arrival has had the most massive effect of species extinction and population reduction

THE PRESENT

My own love and knowledge of  Tasmania fauna started as a small child growing up on the sea front surrounded by native bush teeming with wildlife. An interest in nature, camping and hiking in latter life further developed this. I ended up working at Tasmania's largest Wild Life Park for nearly a year - set in a huge natural bush setting.  I developed much first-hand knowledge of these wonderful and often timid animals. Having since owned a large wilderness block of rainforest in Tasmania's highlands, I had many of these creatures as neighbors and  fellow citizens of my own domain.  I have really learnt to understand their beauty and place in the environment that I live in. Tasmania has been very fortunate that it has managed to escape the ravages of the fox, dingo, and feral cat that have at various stages decimated many species and brought about their extinction on the Australian continent. This could not be more the truth than at my own property at Cradle Mtn. Over the 10 years I have had the place I have tried in vane to plant and grow a few endemic trees, Invariably these, no matter how well protected have been grazed of by either roaming wombats (bush bulldozers - some weighting over 150 lbs and solid ploughing through anything inconveniently put in their path!).

All Tasmanian mammals are nocturnal..... they only come out at night. On dark a cool days sometimes you will catch the odd wombat roaming or wallaby grazing - other than bird sounds often the bush seems quite dead during the day. Strangely this is an adaptation , many Australian Marsupials have poor defences against heat and thus emerge in the cool  of night.  It is in the realm of night that all becomes alive. Many a night I have sat around the camp fire under the starrs and heard the blood curdling growl and shriek of the Tasmanian Devil, the hiss of the wombat, the growl and ticking of a Brushtail Possum or the thud of a wallaby bounding away or gnoring on the cabin timbers of a marsupial rat! . Many of these creatures are extremely timid and difficult to see despite being locally plentiful.

Iti s not till the morning when one can examine the droppings that you really know which creatures have been out in the night. Many areas of grass in alpine areas such as mine, look as if they have been manicured with nail scissors - this is what we call a "marsupial lawn".  My parents whom live some 12 miles out of the city but next to a large eucalypt forest are completely overrun with wildlife in the garden. 

Between the flocks of brightly coloured parrots and lorikeets, the bandicoots, wallabies and possums it is a struggle to grow anything that is not stripped bare especially at fruiting and flowering times. Possums think that Mum's roses are the most tasty things around! Many of the grazing marsupials - kangaroos, possums and wallabies in some areas have done extremely well from whiteman. We have provided them with a great deal more food! Others not so well with predation from domestic pets and white man himself! Due to the isolation and different evolution of much of Tasmania's wildlife it is however highly susceptible to the introduction of disease and competition from introduced species. This has happened at times and wild fluctuations in populations have been noted. The famous Tasmania Devil  now has a population estimated in the range of 400,000 to 1 1/2 million though this has been low as 100,000 due to disease.

 THE FUTURE

Luckily in recent years with a strong and active conservation movement amongst the general public and also amongst the government funded Parks and Wildlife the future looks bright for Tasmania's unique flora. The older attitudes are slowly dying a none-to-soon death of disrespect for our native wildlife. For so long they have been considered vermin to be exterminated at any cost. This was particularly the case with our sealife. During the 1800's Tasmania, especially Hobart was one of the biggest whaling and sealing towns of the world. Both whales and the fur seal where hunted to near extinction in Tasmanian waters. In the early 1800's it was reported that it was dangerous to cross the Derwent River at Hobart due to the number of whales. These wonderful numbers have been very slow to return. Even still outside Australian territorial waters these majestic sea creatures are still at risk of Japanese whalers doing "research'! The Tasmanian Tiger is believe by some to still lurk in the wildest corners of the state.  Out populations of Raptors - Birds of Prey are constantly at risk due to their small numbers. They are highly vulnerable to fluctuations in food supply and the barrel of mans gun - widely unloved still be farmers. Being at the end of the food  chain also they are susceptible to long-term poising by pollution of  poison,and pesticides (used in forestry areas to cull Wallaby/possum numbers and other pollution.) With nearly 20% of the state now in National Parks and many species protected largely the future looks brighter for our wildlife than in most parts of the world.
