Invasive species: A leading threat to Australia’s wildlife

Habitat loss is often assumed to be the main threatening process in Australia, but the evidence indicates that invasive species have caused the most animal extinctions, and pose the main threat to some animal groups.

The evidence for this comes from a number of sources and is summarised in this report, firstly as it applies to threatened species (drawing upon three studies), secondly to threatened ecological communities, and thirdly to extinct animals.

This report was written by Tim Low for the Invasive Species Council.
