Amphibians are among the most threatened vertebrate groups globally, facing habitat loss, disease, and pollution with significant welfare implications for individual animals.
Amphibians infected with chytrid fungus experience disruption of osmotic regulation through skin damage, causing electrolyte imbalance and cardiac failure. Individual amphibians suffering advanced chytrid infection experience a prolonged deterioration before death. Road casualties during breeding migrations result in immediate death for some individuals and traumatic injury for others. Habitat loss forces amphibians to survive in degraded conditions with reduced food availability. The welfare of individual amphibians is most effectively protected through habitat preservation and restoration, disease monitoring, and toad patrol programmes that physically carry animals across roads during breeding migrations.
