“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.”

Conservation managers considering the implementation of nest boxes programs need to give careful consideration to design, colour, placement and shade profile of nest boxes.
The vast brigalow forest that extended from northern New South Wales to southern Queensland has been cleared in the space of 60 years and it seems that many species have become threatened as a result. Rod Fensham and co-workers have identified the plant species that are likely to have become threatened and many of these species were not previously recognised as imperilled.
Monitoring is fundamental to good policy and effective conservation management. Data derived from monitoring underpin the process for listing of species as threatened, which is a precursor to recognition in policy.
TSR Hub researcher David Lindenmayer and colleagues embarked on a four-year case study examining the impacts of a biodiversity offset which established nest boxes to compensate for the losses of natural tree hollows caused by the widening of sections of the Hume Highway (the road linking Sydney and Melbourne).
In recent months you may have noticed some energetic public debate about what is the biggest threat to threatened species in Australia. Is it feral cats and foxes or is it the clearing and degradation of native vegetation?
