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.

What if your pet fish could wreak havoc on Australia's ecosystems? Turns out, that's precisely what they'll do if they end up in our waterways.

In today's episode, Dr. Siwan Lovett sits down with freshwater fish biologist Dr Mariah Millington, who reveals the surprising capacity for non-native pet fish to damage and degrade Australia's freshwater ecosystems, and particularly the native fish that live within them. Discover how to best dispose of dead pet fish, how common goldfish and other popular pet species can grow to alarming sizes and cause severe ecological damage when released, Mariah's undercover research into forums and marketplaces on the Deep web, and some of the specific species which pose significant ecological risks to Australian native fish, whose populations are already estimated to be less than 10% of their pre-colonisation numbers.

Mariah pulls back the curtain on the underground world of illegal fish trade and the challenges in regulating this thriving online market. You'll be intrigued by the prevalence of pet fish in Australian households and the secretive subculture of basement breeders who bypass legal regulations through platforms like Facebook and Gumtree. From the complexities of transporting fish over long distances to the hidden layers of the web where these transactions occur, our conversation uncovers the dark side of the pet fish industry and the ecological risks it poses.

The threats don't stop there—Tilapia and other invasive fish species are making alarming inroads into Australia's waterways. Tilapia in particular continue to head further south. Learn about the reproductive strategies that make tilapia particularly dangerous and the potential for hybridization to increase their invasive potential. Mariah discusses the importance of public education, biosecurity measures, and promoting native fish conservation initiatives.

This episode is a compelling call to action for protecting our native fish populations and the ecosystems they depend on.

Ever wondered what a platypus eats, how to remember native plant names, or what it takes to bring a river back to life? Today, ARRC Director Dr. Siwan Lovett sits down with Jed Pearson from the Rivers of Carbon team to answer some of these questions.

Jed has journeyed from Armidale to the ACT and his dedication to conservation through Waterwatch and Rivers of Carbon has only grown as he has learned on and cared for Country. We dive deep into the importance of riparian zones and the various vegetation layers that contribute to a thriving ecosystem, tackling erosion strategies and a case study on the Gudgenby River in the ACT. Jed explains the challenges of planting vegetation for erosion control and the importance of understanding local flora. We also explore plant identification techniques that, despite sometimes frustrating botanical names, help ensure high survival rates for the vegetation planted. This chapter serves as a valuable guide for those looking to mitigate erosion with site-specific approaches and expert consultation.

Lastly, we journey into the fascinating world of macroinvertebrates and their critical role in waterway health. Through the Rivers of Carbon project and Waterwatch program, we underscore the importance of accessible information and citizen science in monitoring water quality. Jed shares how these tiny creatures act as keystone species and indicators, vital to the diets of platypuses and overall ecosystem health. Jed also shares some very amusing ways to remember tricky species names!

In 2019, the Upper Murrumbidgee River at Tharwa ran dry. Under a burning, smoky sky, flow stopped entirely, and the riverbed was visible except for a few algae-choked pools. This came as a shock for local residents who rely on the river for their water supply, and inspired Andy Lowes to write a letter to Canberrans on behalf of the river. Fast forward to today, and The Forgotten River campaign coordinated by Andy and Dr. Siwan Lovett at the Australian River Restoration Centre has achieved some big wins for the river, including a combined $50 million dollar funding agreement reached between ACT Independent Senator David Pocock and the Albanese Government. The Upper Murrumbidgee still needs more water — Tantangara Dam currently captures between 90% and 99% of its headwaters — but these are big steps towards the rehabilitation of a troubled riparian system.

In this timely and important podcast episode, Australian River Restoration Centre Director Dr Siwan Lovett sits down with Dr Maxine Cooper, Chair of the ACT and Region Catchment Management Coordinating Committee, and Andy Lowes, Chair of the Upper Murrumbidgee Catchment Network, to discuss what has changed since parts of the river dried up in 2019; what the new funding may mean for the river; and what can happen when small group of dedicated, passionate people come together.

This conversation is inspiring, insightful, and a testament to the shared love held by those on Ngunnawal and Ngambri Country, and other traditional Countries, for the Upper Murrumbidgee.

Visit The Forgotten River to learn more about the Upper Murrumbidgee and how you can support this beautiful waterway.

On a crisp Friday morning by the banks of the Cotter river in January 2024, Siwan sat down with Senator David Pocock, the ACT's first independent senator and environmental advocate, to discuss what drives him and what he cares about; his journey towards and inside the world of politics and government; his life growing up in Zimbabwe and career in professional rugby, and more. This is a reflective and insightful conversation, one which reveals a down-to-earth and honest man who deeply cares about the environment we call home.

Siwan and David also discuss the Upper Murrumbidgee, or 'The Forgotten River' — a stretch of river left behind by Federal and NSW water management reforms. As a result, between 90% and 99% of the headwaters of the Murrumbidgee is captured by the Snowy Hydro Scheme each year, which leads to crises like in 2019 when the river almost entirely dried up except for a few algae-choked pools.

The ARRC has been raising awareness about the Forgotten River for a couple of years, and those efforts were rewarded in November 2023 when an agreement was reached between the Albanese Government and Senator Pocock, which ensured a combined $50m of funding for the health of the river, as well as reviews of key legislative documents regarding the regulation of the Upper 'Bidgee. This was a great success for the health of the river and a collaborative effort across the board. The Upper Murrumbidgee still needs more water, but we are hopeful that this agreement sets in motion the ability for these flows to be provided in future years.
