Australia - Fauna and Flora

Although the vast majority of Australia's surface is desert or semi-desert in nature, it has developed many different environments from alpine heathland to tropical rainforest. The long geographical separation has meant that many Australian organisms are quite unique. 85% of plants, 84% of mammals, over 45% of birds and 89% percent of inshore fish are endemic. Many Australian ecoregions and their species are affected by human activity and human introduced animals or plants. There are 64 wetlands registered under the Ramsar Convention and 16 sites are registered as World Heritage Sites.

Many Australian tree species are evergreen, many adapted to resist fire or drought. Examples of these plants include eucalypts and acacia. Australia is rich in endemic legume species that thrive in nutrient-poor soils due to their symbiosis with rhizobia and mycorrhizal fungi. Australia's best-known fauna includes bird-eaters (ptarmigan and hedgehogs), a large number of marsupials including kangaroos, koalas and wombats, and birds (e.g. emus, kingfishers). The dingo was introduced to Australia by Austronesians trading with the indigenous people around 4000 BC. Many plants and animals became extinct soon after human settlement began, and many others became extinct after the arrival of Europeans (for example, the wakwolf).
