Abstract
Australia is a mega-biodiverse region. Millions of years of geographical isolation have resulted in high species diversity and endemism. So far, >21 000 species of plants, 8000 species of vertebrates, and 110 000 species of insects and other invertebrates have been described (Chapman 2009). An exceptionally high percentage are endemic; 93% of flowering plants, >80% of invertebrates, 87% of mammals, 93% of reptiles, 94% of frogs, 74% of freshwater fishes and >50% of temperate marine fishes in Australia are found nowhere else (Lintermans 2013; Cresswell & Murphy 2017). Since European colonisation, Australia's rich biodiversity has been in rapid decline. This decline has been driven by habitat destruction and fragmentation due to land clearing for agriculture and urbanisation; the introduction of invasive plants, animals, and diseases; the disruption of First Peoples practices in caring for Country, including fire management; and the extraction of water including the modification and regulation of freshwater ecosystems. These pressures are now being exacerbated by climate change.
