New research by the Threatened Species Recovery Hub has shown that invasive or pest species are a problem for 1,257 threatened species in Australia, or about four out of five species. The research which has been published in the scientific journal Pacific Conservation Biology also identified the top ten invasive species based on how many threatened species they impact. Lead researcher Stephen Kearney from the University of Queensland said many people may be surprised at which species top the list. “Rabbits, a plant root disease and feral pigs are the top three pest species impacting Australia’s threatened species,” Mr Kearney said.

​Crippled plant industries, trade suspensions and a devastated environment—Australia's Top 40 National Priority Plant Pests have damaging potential, from vine-attacking bacteria to a giant snail. The Top 40 pests were recently endorsed by Plant Health Committee, Australia's top committee for plant biosecurity. They were identified through a national expert elicitation process, which considered the economic, social and environment threats the pests posed to Australia.
