Protecting Victoria’s biodiversity 10.82 MB

Victoria's biodiversity provides the foundations of healthy ecosystems, such as clean air and water, productive soils, natural pest control, pollination and flood mitigation. Threatened species and their habitats are critical to our biodiversity.

Victoria's biodiversity continues to decline. The State of the Environment 2018 report states that a third of all of Victoria's terrestrial plants, birds, reptiles, amphibians, mammals, invertebrates and ecological communities are threatened with extinction.

This audit examines how well the Victorian Department of Environment, Land, Water and Planning (DELWP) is acquitting its responsibilities under the Flora and Fauna Guarantee Act 1988 and in Protecting Victoria’s Environment—Biodiversity 2037 to better protect threatened species.

Key findings:

  • DELWP cannot demonstrate if, or how well, it is halting further decline in Victoria's threatened species populations.
  • DELWP aims to choose cost effective protection actions that benefit the greatest number of threatened species. To this end, it uses modelling tools to support its decisions. These tools are better practice by design.
  • DELWP’s cost-benefit approach can also miss endangered threatened species at extreme risk of extinction. DELWP has no transparent, risk-based process to prioritise these species for management.
  •  DELWP continues to make limited use of available legislative tools to protect threatened species.
