Salamanders face an emerging extinction crisis from Bsal fungus spreading from Asia. Preventing its introduction to North America and Europe is a critical welfare and conservation priority.
Salamander welfare faces an existential threat from Bsal, which causes a skin disease that impairs water and electrolyte balance, causing a slow and agonizing death. Infected animals develop skin ulcers and die from the physiological effects of skin damage. The welfare impact at population scale — billions of individual salamanders — represents one of the largest potential wildlife welfare disasters in history if Bsal reaches North America. Import restrictions on salamanders from Bsal-endemic regions are the primary preventive measure. Decontamination protocols for field researchers and hikers working in affected areas prevent human-mediated spread. Biosecure captive assurance colonies for the most vulnerable species provide welfare refuge for populations that cannot survive in infected habitats.
