Although most of Australia is semi-arid or desert, it covers a diverse range of habitats, from alpine heaths to tropical rainforests, and is recognised as a megadiverse country. Because of the great age and consequent low levels of fertility of the continent, its extremely variable weather patterns, and its long-term geographic isolation, much ...
Sustained climate change could have drastic effects on the ecosystems of Australia. For example, rising ocean temperatures and continual erosion of the coasts from higher water levels will cause further bleaching of the Great Barrier Reef. Beyond that, Australia's climate will become even harsher, with more powerful tropical cyclones and longer ...

[1] The Eastern Mallee and the Western Mallee of Western Australia are areas that are prone to salinity with little remedial action being undertaken to rectify ...
