Western Australia
Western Australia is one of Australia's states, occupying 33 per cent of Australia's land area to the west, excluding outlying areas. The state is home to around 630 bird species, of which around 15 are endemic to the state. The best areas for birds are in the south-west corner of the state and around Broome and Kimberley. Western Australia's flora includes 10 162 published native plant species and a further 1196 currently recognized but unpublished species. The South West region has one of the highest numbers of plant species in the world for its area. Western Australia's ecoregions include the Kimberley sandstone gorges in the north, the drier Victoria Plains tropical savannah inland below, and the semi-desert Pilbara shrublands, Carnarvon xeric shrublands and Western Australian mulga shrublands in the south-west. Deserts occupy the interior, including the Great Sand-Tanami Desert, the Gibson Desert, the Great Victoria Desert and the Nullarbor Plain. Large-scale land reclamation for agriculture has damaged habitats for native flora and fauna. As a result, the state's south-west region has a higher concentration of rare, threatened or endangered plant and animal species than many areas of Australia, making it one of the world's biodiversity hotspots. The southwest coast has a Mediterranean climate similar to California. Originally heavily forested, including large stands of one of the world's tallest trees, the karri. This agricultural area is one of the nine most diverse terrestrial habitats, with a higher proportion of endemic species than most other similar regions. Thanks to the marine Leeuwin Current, the area is one of the top six regions for marine biodiversity and is home to the southernmost coral reefs in the world.
