Protecting Tubbataha Reefs

Located in the middle of the Sulu Sea, the Tubbataha Reefs Natural Park is one of the most biologically diverse marine areas in the world. Its coral reefs shelter hundreds of species of fish, corals, sea turtles, sharks, and seabirds. In recognition of its exceptional ecological value, Tubbataha was inscribed as a UNESCO World Heritage Site in 1993. Unlike many reefs that suffer from overfishing and destructive fishing practices, Tubbataha has been strictly protected as a no-take zone, meaning that fishing and the harvesting of marine life are prohibited. Park rangers, drawn from the navy, the coast guard, and local government, stay on a remote ranger station for months at a time to monitor the area. The results have been remarkable: studies show that fish populations inside the park are far denser than in unprotected areas, and the abundance spills over into surrounding fishing grounds. Nonetheless, Tubbataha remains vulnerable to threats that cannot be stopped by patrols alone, such as coral bleaching caused by rising sea temperatures and occasional ship groundings that crush fragile corals.
