Biodiversity

Australia's Biodiversity (3)

The taxonomic groups in this chart make up a tiny fraction of Australia's biodiversity - an estimated 100 species , in total, 0.02% of estimated species diversity. Nevertheless, all biodiversity is important, and some of these taxonomically tiny groups are particularly important in our understanding of the evolution of life on Earth.

​

The size of each block is proportional to the estimated numbers of species in different groups of organisms (also given as a percentage). The dark section of the pie chart shows the proportion of the estimated species in the group that have not yet been named.

Numbers in this chart are derived from this publication by the Australian Biological Resources Study, updated by taxonomist Gerry Cassis and colleagues in a chapter in this book.

​

Note that some numbers are very uncertain, particularly for hyperdiverse but poorly known groups such as bacteria, nematodes and fungi.
