State of the World's Amphibians: The Second Global Amphibian Assessment

This report, led by Re:wild, Synchronicity Earth, and the IUCN SSC Amphibian Specialist Group, summarizes how amphibians are faring, the pressures upon them, and the solutions needed for massively scaling up their conservation. Through the second Global Amphibian Assessment, more than a decade of research on amphibians by over 1,000 experts has been compiled to assess the extinction risk of 8,011 species worldwide.

The data delivers an incredibly alarming message – 2 in every 5 amphibian species are threatened with extinction, making them the most threatened vertebrate group. The amphibian crisis continues to worsen, as pressures largely driven by human activities take hold. While habitat loss and degradation remain the most common threat to amphibians, an increasing number of species are being pushed to the brink of extinction by disease and climate change effects. The urgency to act is becoming increasingly critical.


Yet, there are reasons for hope. Amphibians have shown us that conservation action works. The report highlights examples of species being saved from extinction, populations recovering, and threats mitigated. We must build on this momentum and significantly scale-up investment in amphibian conservation if we are to reverse the amphibian crisis. The governments of the world have committed to the ambitious goal of halting all human-induced species extinctions by 2050. The State of the World’s Amphibians provides a snapshot of the measures that are urgently needed to meet this goal. The future of amphibians, and our planet, depends on it.
