**Geneva, Switzerland** – A groundbreaking study published in *Nature* reveals a shocking decline in freshwater biodiversity, with a quarter of all freshwater fauna facing extinction. The research, the first comprehensive assessment of threats to these species, highlights the urgent need for conservation efforts in a vastly overlooked ecosystem.
While land and ocean biodiversity often dominate conservation discussions, freshwater environments, despite covering less than 1% of the Earth’s surface, support over 10% of all known species, including a significant portion of vertebrates and fish. Yet, these vital ecosystems are under immense pressure.
The study analyzed existing red lists for fish, dragonflies, and damselflies to assess threats. It found that wetland loss is alarmingly high, with 35% of monitored wetlands disappearing between 1970 and 2015 – three times the rate of forest loss. A further 65% of remaining wetlands face moderate to high threats, and a significant portion of major rivers are no longer free-flowing.
These declines, the authors emphasize, are occurring largely unnoticed, despite the crucial role freshwater ecosystems play in economic growth and human livelihoods. The study serves as a stark warning, urging a shift in conservation priorities to protect these biodiversity hotspots before it’s too late. The researchers call for immediate action to address habitat loss and other pressing threats to safeguard the future of countless freshwater species.
