Science: Fagus Nothofagus gunnii is Australia's only temperate deciduous tree. Australia has always been very hot. So hot in fact that only a few deciduous trees ever evolved. True some have been brought from other countries and the trees do grow in the cooler regions of Australia today. However, except for small pockets in the tropics evergreens predominate. Trees which drop there leaves prefer a fixed unchanging climate. Australia is where the unexpected happens. Like the present where we are having a long hot end to summer and it is unusually wet. Evergreens can adapt and take off when conditions are favorable. When deciduous trees lose there leaves it could rain heavily, but they can no longer absorb the moisture. Conversely, putting out leaves when it dry for months on end is totally ineffective. Hold onto your leaves is the moto. When it rains evergreens are ready to push on to further growth. Australia has one lonely temperate deciduous tree. And wouldn...

Australia is again ignoring advice and is pushing an endangered bird to extinction. There are fewer than 2,000 swift parrots left. Most are taken by sugar gliders. However, destruction of habitat is a major threat. They could be extinct in 15 years. Logging is being allowed in the bird's breeding areas. They do not nest if their natural environment is changed. People have lobbied the Tasmanian government with no success. There is high unemployment in Tasmania and job creation takes priority over birdlife. The swift parrot is already on the endangered list. This does not guarantee any work to save it. If it is put on the critically endangered list something will be done. An application has already been submitted to the federal government. It will take time to get this through the government bureaucracy. ✴ Conservation by Ty Buchanan ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot....

It may be hard to believe, but Tasmania has a thriving truffle industry.  Perigord, the company that began truffle growing in Australia, has a trained team of dogs to search out the valuable product. Something is damaging the crop.  A beetle related to the European truffle beetle has appeared.  Truffle beetles have not been studied to a great extent.  Until now the fungus has been pest free.  In Europe they are also destroyed by flies, gnats, and larvae.  Because the European truffle has only been here for about thirty years, growing them was easy.  The pests have found them and are attacking.  It seems the local beetle likes them too.  Moreover, the European snail has inadvertently been imported. There is a problem in doing research to identify the culprits.  Truffles must be dug up to be examined before they ripen.  Once brought into the light at this early stage they are no good for the market. Using pesticides as is done in Eu...

Tasmania turns the new broadband network on. Well the initial phase has been hooked up and is working. The project is going to be a vast enterprise with optical fiber being laid in place of copper. It will offer consumers video streaming that is 100 times faster than at present. The difference will seem magical to most people. Hopefully and I mean hopefully it will be no more expensive than existing services. The Government has promised that it will be cheaper, a miserly $29.95 a month. Time will tell on the price. The service is being set up as a virtual non-profit business, a public system aiming for only 6 percent profit. Apparently, e-health is coming to Australia. Patients will be monitored from home. In the Us such a system has resulted in hospital admissions being cut by 60 percent. Sick children will receive schooling direct to their sick bed. Buildings will become 'alive' with remote monitoring cutting power bills. Traffic lights will be synchronized. Mobile connectiv...
