Where is the Coral Triangle?
The triangular marine area that makes the Coral Triangle lies in the western Pacific Ocean occupying only about 1.6% of the world’s oceans but referred to as the epicenter of marine biodiversity.
This 6 million km2 area includes the waters of:
- Papua New Guinea
- The Philippines
- Timor Leste
- Solomon Islands
Why is this area so diverse?
There are many facts that explain the region’s extreme biodiversity. One reason is that the array of habitats including volcanic islands, rocky beaches, sandy shores, and mangrove forests made the marine species here to adapt to a wide range of conditions.
The other explanation comes from the geographical situation. Since the Triangle sits where the Pacific and Indian Oceans overlap, species from both bodies of water colonize the reefs, moreover the currents bring in other species from other regions, like The Maldives too. This phenomenon is not only increasing the number of marine creatures living here, but their mixing forms new ones too.
On top of this, because of this complexity the Triangle’s coral and fish species are more resilient against climate changes and there is a chance will withstand the impacts better than the world’s other reefs.
Facts about species in Coral Triangle
Giving home to about 30% of the world coral reefs, the tropical waters of the Coral Triangle are unique from various aspects:
- 75% of all known (nearly 600) coral species can be found here
- there are over 2000 types of fish as well as various marine mammals including sharks, whales, whale sharks, dugongs, reef and oceanic manta rays, porpoises and dolphins.
- this is the only region in the world where 6 out of the world’s 7 marine turtles are present
- the area has large tuna population which is a multi-billion-dollar industry
- the reefs are not only providing people with food and attract tourists but also play a key role in protecting the countries from storms by acting as natural barriers. They soften the power of waves, tsunamis and typhoons and lower the risk of flooding events
Why is the Coral Triangle endangered?
Unfortunately, like all over the world, the coral reefs here are also in danger and most threats are caused by humanity. The current level of fishing and the used methods such as dynamite fishing, bycatching are not sustainable and destroying not only the fish population, but also the reefs.
Climate changes related effects are the other main problems in the Coral Triangle. Warming sea temperatures and ocean acidification cause coral bleaching. This happens because the reef-building algae cannot survive if the water is acidic or the temperature is too high for a longer period, so they leave the coral skeleton making the reef dead.
The increased number of tourists also poses a potential risk to the area. Mass tourism puts pressure on nature from several sides: it makes unregulated coastal developments are more likely to happen as well as causing direct and indirect environmental damages.
Plastic pollution and toxic chemicals found in sun care products are just some of the most known threats that lead to habitat degradation, but we can’t forget about extractive industries (gas, oil and mining) that pollute these fragile underwater ecosystems and killing marine species.
These problems are already happening not only in this region but worldwide and causing irreversible damage if serious actions are not taken immediately.
