Bird Flu Threatens 1 in 5 Australian Species
5 Aug
Summary
- Nearly 20% of Australian birds and mammals at high risk from bird flu.
- Five bird species face extreme risk, potentially leading to extinction.
- Environment department data reveals widespread threat across the continent.
New data indicates that nearly 20% of Australia's native bird and mammal species are at significant risk from the H5N1 bird flu virus. Five bird species are categorized as being at extreme risk, meaning they may not survive where the virus is present. This assessment highlights the potential for severe population declines or even extinction among vulnerable fauna.
The risk calculation considers both animal susceptibility and conservation status, with species having limited ranges or congregating in high-transmission areas like waterbird colonies being more vulnerable. Marine mammals such as seals and land mammals like the Tasmanian devil are among those identified as highest risk.
Environmental groups have expressed shock at the scope of the threat, criticizing the late release of the data and cuts to environmental programs. They argue that the government's current preparedness measures are insufficient given the broad impact of the virus, which has already been confirmed in South Australia.
Environment Minister Murray Watt stated that $113 million has been committed to surveillance and response, and Australia has learned from global experiences. However, experts are calling for transparency regarding specific actions taken and their effectiveness in better preparing wildlife for this large-scale threat.
