Three TSR Hub researchers will present their work to the 11th Australasian Plant Conservation Conference (APCC) at the Royal Botanic Gardens
Victoria, Melbourne this week.
The APCC will focus on the theme “New Approaches to Plant Conservation Challenges in the Modern World”.
Threatened Species Commissioner Gregory Andrews will deliver the keynote speech, presenting the Australian Government’s Threatened Species Strategy and introducing 30 plants the government has committed to saving from extinction.
Dr Jen Silcock of the University of Queensland will deliver the first plenary lecture of the conference, recounting her efforts to systematically survey plant species across south-western Queensland. She has logged more than 3000 hours of field time and gathered data on 2000 separate populations over the past 10 years.
“The criterion that allows listing of species because of extreme fluctuations (in combination with restricted and fragmented populations) must be carefully interpreted in arid zones,” says Jen.
“These fluctuations may be apparent rather than real and can confer resilience to grazing.
“A systematic survey approach facilitates robust conservation assessments across vast and poorly known regions, distinguishing species that have merely been lost in space and time from those that are at risk of extinction.”
She will also introduce and provide an update on the Red Hot list of Australia's most endangered plants (NESP TSR Hub Project 2.1).
TSR Hub research scientist Leonie Monks (The Department of Parks and Wildlife, Science and Conservation Division, WA) will introduce her work in a presentation titled “Translocation principles and practice: opportunities and challenges for threatened plant recovery".
“Translocations aim to prevent species extinction by creating or maintaining viable populations and are increasingly being undertaken world-wide in an attempt to stem the tide of biodiversity loss,” says Leonie, who works on the NESP TSR Hub’s Threatened plant reintroduction and relocation ( Project 4.3).
Leader of Project 4.3, Dr David Coates (also from The Department of Parks and Wildlife), will present his work on rescuing small populations from extinction.

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?
