Australia is one of the world's 17 centres of 'mega-diversity' of plants and animals.
The south-west of Western Australia is known as one of the world's 34 biodiversity ‘hotspots’, with some of the richest and most threatened reservoirs of plant and animal life on earth.

Western Australia is also renowned for its unique plants.
From the forests of our south-west to the spinifex grasslands and saltbush of central Western Australia, and the boab trees of the Kimberley, our diverse plant life is treasured by locals and visitors alike.
Despite the efforts of many botanists and amateur naturalists since European settlement, much still remains to be discovered about our plants. We do not know the precise number of species present in Western Australia—the figure is thought to be about 13,000, of which around 3,000 species are yet to be formally named. Current information is available through the Department of Parks and Wildlife's WA Herbarium.
Parks and Wildlife has a key role in protecting our native plants and animals, and does so through the management of lands and waters reserved under the Conservation and Land Management Act, a range of conservation initiatives operating on other lands, the activities of the WA Herbarium, and programs such as Western Shield, Saving our Species, scientific research and the protection of threatened species and ecological communities.
