Biological diversity


Theme: Sustainable
Dimension: Protect, repair and manage the environment


Proportion of decline in Australia’s threatened and near threatened species from the “Threatened Species Index”

Why does this matter

Biodiversity — the variety and variability of living things including animals, plants, fungi and microorganisms like bacteria — is central to the health of natural ecosystems. A loss of biodiversity threatens the capacity of our environment to sustain and provide clean air, water, medicines and is contributing to the emergence and transmission of disease.1

Has there been progress

Australia’s threatened and near threatened species populations are continuing to decline, at an average rate of 55 per cent in relative abundance in 2019 compared to the 1985 baseline for the 278 species represented.2
