In the Palau Bontosua area, in the southwestern portion of the Indonesian island of Sulawesi, all the degraded coral reefs have been restored in just four years.Due to global warming and human activities, the coral reefs in the area had been virtually destroyed.But now, thanks to a specific restoration program, they are growing at the same rate as healthy ones.To allow the corals to reform, barriers have been installed hexagonal steel structures covered with sand, which stabilizes debris and provides a habitat for reef fauna.However, although this is an excellent result, the researchers warn that the technique used represents a last resort which should not be used systematically.The barriers thus restored present in fact a lower species diversity compared to healthy ones. A team of Indonesian and British scientists worked on the project as part of the Mars Coral Restoration Program, a large-scale effort to restore the coral reefs destroyed by fishermen who used explosives to kill and c...
