Amphibians are among the most threatened major groups, with one-third or more of species at risk.

Amphibians, including frogs, salamanders, and caecilians, are highly sensitive to environmental changes and have small geographic ranges, especially in tropical regions. This makes them particularly vulnerable to habitat loss, climate change, pollution, and diseases like chytridiomycosis, a fungal infection devastating populations worldwide. Their plight highlights the broader biodiversity crisis and serves as an early warning of ecosystem collapse.
