37% of Australia's freshwater species are facing extinction in the next century. In the words of today's guest, Dr. Nick Whiterod, "it is now a conscious decision not to act."

Native fish populations in Australia are estimated to be less than 10% of their size pre-colonisation. This country has experienced one of the worst records of recent extinctions worldwide, and many more of our species are predicted to be lost in the near future – not unless we act now. Freshwater species have a disproportionately higher risk of extinction compared to terrestrial and marine counterparts, but are often overlooked, with few aware of how much trouble they’re really in. Dr. Nick Whiterod is a leading expert in the field of freshwater species conservation and recovery, and there’s no one better to speak with about this great challenge than him.

Nick is the driving force behind the Science Program at the Coorong, Lower Lakes and Murray Mouth (CLLMM) Research Centre based in Goolwa, South Australia. He is an ecologist with over two decades of experience, conserving and researching freshwater species and ecosystems across South Australia and Australia-side. He has conducted several successful reintroduction projects, contributed to the national listing of more than 50 freshwater fish and crayfish, and actively worked to understand and conserve freshwater fish across Australia, including in the Mt Lofty Ranges and the Coorong, Lower Lakes and Murray Mouth region. Nick was a 2018 Churchill Fellow and recently received the 2023 Unsung Hero of South Australian Science.

In today's show, we unravel the ecological treasures of this breathtaking Ramsar site at the Murray-Darling Basin's end. Nick opens up about the region's unique freshwater ecosystems and the pressing challenges they face, from reduced water flows due to upstream extraction to the historical necessity of barrages that protect the freshwater supply. We discuss the significance of environmental water flows and the complexities of managing water resources across jurisdictional boundaries; dive deep into the urgent need for conservation and the threats faced by Australia's native freshwater species; highlight the importance of First Nations collaboration in conservation efforts, and more.
