Singapore’s Important Biodiversity and Bird Areas


Birdlife International Important Biodiversity and Bird Areas (IBA) program helps countries worldwide to identify, protect and manage significant sites of naturally occurring vulnerable bird species and population. It is based on internationally recognized Criteria. Over 10,000 sites have been identified worldwide.

The Nature Society (Singapore) and the Bird Group have identified three such IBAs in Singapore using the accepted international criteria. This is quite significant for a city state like Singapore with one of the highest population density in the world. These IBAs must be protected for the natural health of the island and its people.

They are A) Central Forest B) Kranji-Mandai and C) Ubin-Khatib.
