Wild Amphibian Disease and Chytrid Welfare

Chytridiomycosis caused by Batrachochytrium dendrobatidis has caused the greatest disease-driven vertebrate extinction event in recorded history.

Key Facts

Bd chytrid fungus has caused extinction of over 90 frog species and decline of 500+ more
UK amphibians show low Bd prevalence but the related Bsal threatens salamanders severely
Chytrid disrupts electrolyte balance through skin damage causing cardiac arrest
Probiotics on frog skin may offer disease resistance to some populations
Global amphibian declines have ecological cascading effects on predator populations

Welfare Considerations

Chytridiomycosis causes individual frogs to experience progressive physiological collapse leading to cardiac arrest. The scale of welfare harm at population and species level is immense. Prevention through biosecurity and captive assurance populations is the primary welfare intervention.

What You Can Do

Follow biosecurity protocols when moving between water bodies to prevent disease spread
Support amphibian conservation organisations managing chytrid risks
Advocate for biosecurity requirements for amphibian trade and import regulations
