“If there was an ark for Australia's most endangered species, what animals and plants would get a berth?”
That was the question interviewer Gregg Borschmann put to the TSR Hub’s Associate Professor Brendan Wintle and Professor David Keith when they took part in a panel discussion at the Australian Museum as part of National Science Week.
The discussion followed a screening of Attenborough's Ark in which conservation icon David Attenborough profiled 10 species he would include on his ark.
Also on the panel was Dr Rebecca Johnson, Director of the Australian Museum Research Institute, and Dr Rebecca Spindler, Head of Conservation Science from Taronga Zoo. The discussion was recorded as part of the 2016 Australian Museum Science Festival, and broadcast ABC’s Radio National.
Brendan Wintle told the audience that 45% of Australia’s birds and 90% of Australia’s mammals do not exist anywhere else in the world.
“As Australians, we have the privilege of living amongst them, but this is also a responsibility.
“We have at least 1700 species very close to extinction...”
Brendan put the Golden Sun Moth on his ark because “it is so good at stopping urban developments in critically endangered basalt plains grasslands”.
David Keith spoke about the importance of conserving the ecosystem, not just the species, and he used an unusual, Hollywood-technicoloured orchid as an example.
“It’s an orchid that’s pollinated by male wasps who are deceived into thinking the flower is a female.
“The reason this works is the plant has evolved to produce a pheromone that mimics the pheromone of the wasp species.
“And recent work has shown the evolutionary tree of the orchid’s pheromone versus the wasp’s as almost mirror images of one another.
“With relationships like this it speaks volumes for conserving the whole rather than little bits of it.”

The exceptionally long-beaked far eastern curlew is the world’s largest migratory shorebird. It is also one of the most well-travelled. This globe-trotting bird was listed as Critically Endangered in Australia in 2016, with its numbers in rapid decline since it was first listed as Least Concern in 2004.
A new video summarises the findings of a University of Queensland PhD project on northern quolls in the Pilbara. Once found all the way from Brisbane to the Pilbara, quolls are now listed nationally and internationally as Endangered, and are restricted to just a few isolated populations, mostly on rocky habitats.
On average, populations of Australia’s threatened birds have decreased by half since 1985, according to Australia’s new Threatened Bird Index.
Many researchers in, and stakeholders of, our Hub have long expressed concern about the loss of biodiversity in Australia. Recently, this concern has been recognised by politicians as a national problem, with the Australian Senate currently holding an Inquiry into ‘Australia’s faunal extinction crisis’.
New research led by the Threatened Species Recovery Hub has revealed which mammals are most vulnerable to cats and foxes, and many much-loved potoroos, bandicoots and bettongs, as well as native rodents, are at the top of the list.
