DARWIN’S FROG

NEWS – The Chilean government’s Climate Change and Sustainability Committee has launched a public–private conservation programme to protect the endangered Darwin’s frog, known for its unique reproductive behavior.

HIGHLIGHTS

Key strategies include:

  • Protecting and expanding habitats
  • Collaborating with private landowners
  • Conducting targeted surveys to discover new populations
  • Raising public awareness of the frog’s ecological role

About the Species

  • Rhinoderma darwinii (Southern Darwin’s frog – Endangered)
  • Rhinoderma rufum (Northern Darwin’s frog – Critically Endangered / Possibly Extinct)
  • Habitat: Temperate rainforests of southern Chile and Argentina, including the Valdivian forests and Chiloe Island
  • Unique trait: Male mouth-brooding, where tadpoles develop inside the male’s vocal sac

Major Threats

  • Chytrid fungus outbreak in 2023 caused a 90% decline in Tantauco Park
  • Other threats:
    • Habitat loss from fires and urbanisation
    • Climate change and invasive species
    • Severe fragmentation – only ~62 known groups remain
    • R. rufum not seen since ~1981

Rescue & Recovery Efforts

  • October 2024: 52 chytrid-free frogs rescued by ZSL and Chilean partners
  • 33 froglets successfully bred in London Zoo via male brooding
  • Marks success in ex-situ conservation; in-situ efforts continue in Chile

Strategic Actions Ahead

  • Strengthen habitat connectivity
  • Partner with landowners
  • Expand monitoring efforts
  • Promote nationwide awareness campaigns
