Threats

  • Increasing numbers of amphibians are being affected by Chytridiomycosis, a lethal fungal disease that has entered the country through frogs imported as food for aquarium fish.
  • A large population of amphibians in the Ryukyu Archipelago is threatened due to loss of habitat where deforestation from logging, wood harvesting and urban development are seen as the major causes of habitat decline.
  • The native amphibian biodiversity in Ryukyu Archipelago is threatened by introduced alien species that are rapidly expanding their geographical range.
  • Deforestation has resulted in the disturbance of natural river flow in areas populated by amphibians. Soil erosion and runoff created by this phenomenon further adds to the loss of amphibian habitats.
  • Reduction in the quality and quantity of inland water environments is a major contributor to declines in several endemic amphibians on the main islands of Japan.

Conservation Actions

  • The Japanese giant salamander is now protected from international trade as it is listed in Appendix I of the Convention of International Trade of Endangered Species (CITES) which hopefully will reduce the hunting threat facing this animal.
  • Tokyo Zoological Park Society is undertaking a major amphibian conservation awareness effort by creating partnerships with zoos and aquariums in Japan and focusing on research activities related to amphibian conservation.
  • Land and water management techniques modified to minimize the impact on amphibians.
  • Measures taken to protect habitats and key resources of amphibians.
  • Restoration of habitats and natural processes.
  • Introducing legislation on a sub-national level to protect amphibians.
