Coral Triangle Day: History and How We can Celebrate it

Coral Triangle is the biggest reef system that covers almost 132,636 km area in the Western Pacific Ocean. This reef system passes through 6 countries- Indonesia, Malaysia, the Philippines, Papua New Guinea, Timor-Leste, and the Salomon Islands.


Coral Triangle holds just 1.5% of the total ocean area across the globe, but the world’s 30% coral reefs are the contribution of this reef system. This place is known to have the highest coral diversity, approximately 76% of the world’s coral species. This reef system is a home for a huge range of coral reef fishes in the world. 

This triangular-shaped coral reef area plays a vital role in marine diversity, but the unfortunate facts are that it is under threat. The coral triangle countries (CT6) came forward to work together for the protection and conservation of marine diversity at the coral triangle region, which is known as the epicenter of marine diversity.

The emergence of Coral Triangle Day

Coral Triangle Day was established by CTI-CFF (Coral Triangle Initiative on Coral Reefs, Fisheries, and Food Security) for the conservation of coral reefs diversity. CTI-CFF is a multilateral partnership of the six countries across the region, i.e., CT6 that works together to save marine resources, coastal areas, oceanic biodiversity, etc. from the adverse effects of environmental pollution.    

The day was celebrated on 9th June 2012 for the first time in conjunction with World Oceans Day. CTI-CFF observed this day to raise awareness about marine conservation, mainly focusing on the coral triangle region.  

Coral Triangle Day is celebrated every year in different locations of CT6 countries, highlighting the protection of coral reefs of this region. On this day, the individuals, organization, etc. contribute through various activities such as coastal clean-up tasks, planting mangrove trees, beach parties, fashion shows, contests, ocean film festivals, seafood exhibitions, etc.
