While media reports often focus on the doom and gloom of species sliding to extinction, it is important to also take note of where we are succeeding. Hub
Deputy Director Professor Stephen Garnett talks about the importance of learning from conservation successes and celebrating how far we have
A hundred years ago the global catastrophe that was the First World War came to an end. Today it is inconceivable that slaughter of people on such a scale would be tolerated, as world views are changing. And so it is with conservation. A hundred years ago most people would have been baffled by the conversations we now have about threatened species. Even fifty years ago conservation was a new concept to many, extinction seen as an inevitable, if slightly regrettable, by-product of development. A book on successful conservation of threatened species, such as Recovering Australian Threatened Species: A Book of Hope (CSIRO Publishing), could not have been imagined.
Now it can. Surveys show over 80% of Australians do not want further extinctions, and they are willing to invest in preventing them. Changing attitudes are also reflected in our evolving legislation. Australia’s earliest environmental legislation was created to reduce hunting of birds and only became concerned with threatened species in the latter part of the 20th century. It is still evolving in response to societal expectations but both legislation and policy are increasingly explicit about preventing extinction.
At the same time, governments, non- government organisations and private individuals have all made major contributions to ameliorating threats once they have become known. Often particular champions have stepped forward to ensure a species is not lost for future generations and put in extraordinary efforts to turn population trajectories around. As one of the editors of the Book of Hope, along with Peter Latch, David Lindenmayer and John Woinarski, I had enormous pleasure working with many such people, some of whom had dedicated over half a century of their lives to particular species.
This says something about species recovery – it needs to be given time. Often declines have been slow, and their reversal can take decades. When a pair of glossy black-cockatoos produce one young a year at the most (see box), and often raise none, supporters of programs must have patience from the start. Even identifying how to reverse declines can take a long time. For example efforts to recover the Helmeted Honeyeater yielded dismal results until only a few years ago when suddenly a new technique, supplementary feeding of wild birds, seemed to push them into overdrive.
A vital first step in any successful recovery program is understanding the problems that need solving.
In the Book of Hope, each case study describes the research phase that has guided recovery action. The great thing is that knowledge begets knowledge. What works on one species can work on others. New technologies – digital, genetic, electronic - are being applied in ways that would have been unimaginable a decade ago. In many ways it is a thrilling time to be a researcher.
Society is also changing. Indigenous people are becoming increasingly involved with threatened species recovery on their land and sea country. Many Indigenous people have been greatly distressed by the loss of small mammals that were abundant just a few decades ago. Now many Indigenous ranger groups are seizing the opportunities provided by threatened species management to bring country back to life.
The Book of Hope began with a workshop in 2016. The Threatened Species Recovery Hub brought together 40 conservation managers and researchers wanting to learn from and share existing successes in threatened species recovery work. The results, now compiled in the book, are 35 case studies of conservation success and a framework of seven factors that were found to be important to success. The book’s launch has also brought many more people and examples of successful conservation forward.
Overall working on the Book of Hope was a huge privilege, just as it is to be undertaking threatened species research. The next step is to ensure that its messages reach the right people so they too realise what a long way we have come and that threatened species recovery is possible when we have commitment and investment. The success stories are also a reminder to those supporting threatened species conservation that their investment of time and money is worthwhile.

An inspiring showcase of conservation success stories
Against a relentless tide of threats to our biodiversity, many Australians, and government and non-government agencies, have devoted themselves to the challenge of conserving and recovering plant and animal species that now need our help to survive. This dedication has been rewarded with some outstanding and inspiring successes.
Recovering Australian Threatened Species: A Book of Hope (edited by Stephen Garnett, Peter Latch, David Lindenmayer and John Woinarski and published by CSIRO Publishing) showcases 35 of these stories and identifies the common factors that have been most effective in recovering threatened species.
The diverse case studies – dealing with threatened plants, invertebrates, fish, reptiles, birds and mammals – show that the conservation of threatened species is achievable: that it can be done and should be done. They collectively serve to inform, guide and inspire other conservation efforts.
The Book of Hope is available to purchase online at: www.publish.csiro.au/book/7705
Many landscapes in Australia are fire-prone, and increasingly so. Altered fire regimes can have a serious negative impact on threatened plant species and ecological communities. A Threatened Species Recovery Hub project is working to better understand the effects of different fire regimes on threatened flora in order to improve fire management strategies and conservation outcomes.
Almost a quarter of Australia’s possums and gliders are listed as threatened under Australian environmental law, and many more are showing signs of decline. Dr Rochelle Steven from The University of Queensland believes people in the community can do a lot to support conservation, especially in urban areas.
The detection and monitoring of threatened species have been a strong area of research in the National Environmental Science Program and also the two national environmental research programs which preceded it. Hub Director Professor Brendan Wintle takes a look at what we’ve been achieving and why it is so important to the conservation of Australia’s threatened species.
In 2009, the Christmas Island blue-tailed skink and Lister’s gecko were headed for imminent extinction. Parks Australia acted quickly to collect remaining wild individuals in order to establish captive breeding programs on Christmas Island and at Taronga Zoo, Sydney, which have been highly successful. A Threatened Species Recovery Hub project team is working closely with Parks Australia to help secure a future for the two lizards beyond captivity.
The silver-headed antechinus and black-tailed dusky antechinus are carnivorous marsupials found in high-elevation forests in parts of central-eastern and south-eastern Queensland. They were only described in the past six years, but they are already listed as Endangered. Knowing where they occur is essential for effective conservation, but current distribution knowledge is patchy. To address this, PhD candidate Stephane Batista in partnership with the Queensland Herbarium and Queensland Department of Environment and Science is modelling the habitat where these threatened species are likely to occur, and is using detection dogs to rapidly survey these sites.
