Gina will talk about the critically endangered wetlands and floodplains of the lower Murray, downstream of the Darling, her involvement in the ecological assessment, and what needs to be done.
Abstract
As of February 2026, the lower Murray River, its wetlands, and floodplains downstream of the Darling River are listed as Critically Endangered under Australian national environmental law, facing imminent ecosystem collapse within a decade.
Critically Endangered Listing: The listing applies specifically to the Lower River Murray, including the Coorong and Lake Alexandrina, because of systemic ecological decline.
Key Threats: The system is heavily impacted by climate change, excessive water allocation, flow regulation (dams, weirs), salinisation, and acidification.
Scientific Involvement: Dr. Gina Newton has previously undertaken large-scale aquatic assessments to list endangered ecosystems like the River Murray.
Ecological Impact: The river has lost significant habitat complexity, including old-growth vegetation, and faces high pressures on native flora and fauna.
The emergency status suggests that urgent, long-term restoration efforts are necessary to avoid ecological collapse of this vital waterway.
