The Coral Triangle

The Coral Triangle (CT) is a globally significant marine area located in the tropical waters around Indonesia, Malaysia, Papua New Guinea, the Philippines, the Solomon Islands, and Timor-Leste. This region, often referred to as the "Amazon of the seas," is known for its extraordinary marine biodiversity, housing at least 500 species of reef-building corals in each ecoregion.

Geographic and Biological Significance

Situated between the Pacific and Indian Oceans, the Coral Triangle encompasses two distinct biogeographic zones: the Indonesian-Philippines Region, and the Far Southwestern Pacific Region. Covering approximately 5.7 million square kilometers (2,200,000 sq mi) of ocean waters, it is one of the eight major coral reef zones in the world and is recognized as a global center of marine biodiversity.

This area is a critical habitat for a wide array of marine life, including over 600 species of scleractinian corals and 12 endemic coral species. The Coral Triangle supports the greatest diversity of coral reef species on Earth, which provides essential ecosystem services such as supporting fisheries and tourism, and contributing to coastal protection.

Economic and Environmental Impact

According to the Asian Development Bank, the Coral Triangle's marine ecosystem contributes an estimated $1.2 trillion annually to the region’s gross domestic product (GDP). This wealth is primarily derived from fisheries, tourism, and marine biodiversity that sustain over 120 million people living in the area. The health of coral reefs within this region is vital for food security, livelihoods, and economic stability.

Conservation Efforts

Recognizing its global importance, multiple initiatives such as the Coral Triangle Initiative on Coral Reefs, Fisheries, and Food Security (CTI-CFF) have been established. These initiatives aim to ensure the sustainable management of marine resources, promote biodiversity conservation, and address the impacts of climate change and other anthropogenic pressures.

The Coral Triangle Day, celebrated annually on June 9th, serves to raise public awareness about the need for ocean conservation and protection of this vital ecological region.
