Why should we care?
- Amphibians are among the oldest organisms on earth, having survived the last five mass extinctions.
- They play a tremendous role in ecological studies due to their ability to act as bio-indicators, representing climate change and environmental stress.
- They are a tremendous ecological asset due to their ability to act as both predator and prey, thereby maintaining a balance of nature.
- Amphibians are found to be very useful for agricultural purposes due to their ability to act as a biological pest controlling agents.
- They can help control the spread of diseases, such a malaria, by controlling the population of vectors such as mosquitos.
- Compounds derived from amphibian skin offers a promising pathway towards new medicinal discoveries.
- Amphibians have played an important role in human culture, from religion to fables and traditional medicine.
- 122 amphibian species have become extinct in the last 25 years.
- The current rate of amphibian extinction is 211 times the background amphibian extinction rate.
- One-third of the world’s 6,000 amphibian species are under threat of extinction.
- 427 of the world’s amphibian species are listed as Critically Endangered by The IUCN Red List of Threatened Species.
- 38 species that are classified as Extinct in the most recent Red List are indigenous to Asia.
- 21 of these species are native to Sri Lanka.
Habitat loss destroys the ecological balance of amphibian communities and represents the most critical threat to amphibians worldwide. These threats are compounded by:
- Human encroachment into their habitats
- Climate change
- Pollution and pesticides
- Introduced species
- Over-exploitation for food and pet trade
In recent years a new threat has developed - Chytridiomycosis - a previously unknown pathogenic killer fungus (Batrachochytrium dendrobatidis) that is now spreading rapidly worldwide and depleting amphibian populations.
