Amphibian Chytrid Disease and Conservation Response

Chytrid fungus has caused more vertebrate extinctions than any other pathogen in recorded history, requiring emergency conservation responses to protect surviving amphibian populations.

Key Facts

Batrachochytrium dendrobatidis (Bd) has contributed to the decline of over 500 amphibian species
At least 90 species extinctions are attributed to chytrid since the 1970s
Chytrid infects amphibian skin, disrupting electrolyte absorption and causing heart failure
Panama's golden frog is now extinct in the wild, surviving only in captive breeding programmes
Some species show evidence of evolving resistance to Bd after exposure in affected populations
Probiotic bacteria that inhibit Bd growth are being trialled as a field conservation tool

Welfare Considerations

Chytrid disease causes suffering and death in affected amphibians through a process of skin disruption leading to cardiac failure. The scale of impact - hundreds of species affected, dozens extinct - represents one of the most significant ongoing welfare and conservation crises affecting any animal group. Emergency conservation responses including captive assurance colonies, habitat biosecurity and probiotic treatment aim to protect surviving populations. Individual amphibians in captive breeding programmes benefit from welfare-appropriate conditions that support reproduction and disease resistance. The welfare and conservation goals are aligned here - healthy animals survive and reproduce.

What You Can Do

Support Amphibian Ark and Panama Amphibian Rescue and Conservation Project
Never release captive amphibians or aquarium water into the wild
Practice biosecurity when visiting amphibian habitats: clean equipment between sites
Donate to chytrid research including probiotic treatment and vaccine development
Support wetland and forest conservation to maintain amphibian habitat resilience
