Authorities are actively working to protect wildlife from extreme heat, with bats facing a particularly high risk of mortality. Veterinarians, volunteers, and other workers are preparing for a demanding period focused on the grey-headed flying-fox colony located at Yarra Bend in Kew, northeast of the city.
Protecting Vulnerable Species
Bats begin to experience heat stress when temperatures reach 38 degrees Celsius, and fatalities increase significantly at 40 degrees Celsius, especially when shade and water are unavailable. Parks Victoria has activated a treetop sprinkler system in response to temperatures exceeding the high 30s, and personnel are providing direct assistance to individual animals.
Wildlife Victoria deployed crews to central Victoria on Saturday to monitor these colonies. While both colonies are currently reported to be doing well, conditions are anticipated to deteriorate as the region experiences multiple days of intense heat.
“Right now, we are solely focused on wildlife welfare,” stated Lisa Palma, chief executive of Wildlife Victoria. “We are extremely busy responding to reports of sick, injured and orphaned wildlife, animals affected by bushfires, and grey-headed flying foxes under extreme duress. We will provide updates to our supporters as we are able but ask for patience as we navigate the coming days and weeks.”
As temperatures are expected to remain high, wildlife services will likely continue intensive monitoring and intervention efforts. Further strain on resources could occur if heatwave conditions persist, potentially impacting the ability to respond to all wildlife in need. It is possible that additional support from volunteers and the public may be requested in the coming days.
