Victoria facing wave of extinctions


An alliance of leading environment groups today expressed alarm at the state of Victoria’s much-

loved native birds, following the release of new research which shows that in northern and central

Victoria, a shocking two thirds of woodland bird species have declined dramatically over the past

five years. 


The research was undertaken by leading ecologists, Professor Ralph Mac Nally, Director of the

Australian Centre for Biodiversity at Monash University, Professor Andrew Bennett and Dr Jim

Radford at Deakin University and Dr Peter Vesk from The University of Melbourne.


The extensive study was carried out across 30,000 km² of northern and central Victoria and

revealed many woodland bird species, including honeyeaters, pardalotes, thornbills and lorikeets,

were in sharp decline.


The scientists believe the sharp falls in numbers are due to climate change, particularly reduced

rainfall, coupled with the extensive loss of habitat in the region over more than 150 years.


“The collapse in bird numbers strongly suggests the availability of food has crashed,” Professor

Bennett said.


“The flowering of Red Ironbark trees, which provide an important food source for nectar-feeding

birds, has become less frequent with the drought.  In five of the past eight years Red Ironbark

eucalypts have flowered little or not at all.


“Most worrying, species thought to be secure, such as the Red Wattlebird and the Laughing

Kookaburra, have declined as much or more than species already considered endangered.”


The study found little evidence of successful breeding, suggesting that there were no young birds to

replace those that died. It also showed that species have declined within large areas of bushland,

including in national parks. 


Victoria Naturally Alliance spokesperson Karen Alexander said the research findings are a dire

warning that Victoria could be facing a wave of extinctions.


“We are deep in an extinction crisis and urgent action is required. This research has shown that we

can no longer rely on national parks for long-term protection of our species in a drying, warming

climate,” she said.


“There is a critical need to improve the quality of existing habitats and restore habitats especially in

more fertile areas adjacent to existing bushlands.


“According to CSIRO, 30 per cent of Victoria’s animals and close to half our plant species are

already extinct or threatened with extinction. And now climate change is hitting our remaining

species hard.


“This research is a wake-up call for the State Government to put a major injection of funding into

the protection and restoration of our natural environment.”
