Global Amphibian Decline: Welfare and Conservation

Amphibians are the most threatened vertebrate class globally, with chytrid fungus causing mass mortality events of profound welfare significance.

Key Facts

Over 41% of all amphibian species are threatened with extinction
Chytrid fungus Batrachochytrium dendrobatidis has driven over 90 species to extinction since 1980
Chytrid infection prevents amphibians from absorbing water and electrolytes through skin, causing heart failure
Climate change and habitat loss compound disease effects on already stressed populations

Welfare Considerations

Chytrid fungus causes slow death over 1-2 weeks through disruption of skin function in species that depend on cutaneous respiration and water balance. Mass mortality events at breeding aggregations cause enormous individual suffering at scale. The welfare dimension of biodiversity loss is rarely acknowledged in conservation framing focused on species counts.

What You Can Do

Never release aquarium amphibians or move amphibians between water bodies to prevent disease spread
Support amphibian conservation captive breeding programs through donations
Advocate for biosecurity measures at field sites to prevent chytrid spread
Report dead or dying amphibians to wildlife disease monitoring programs
