Coral tray propagation project. In 1998, unusually warm oceanic waters caused by an exceptionally strong El Nino event bleached and killed corals across a large portion of the Maldivian reefs. Four Seasons Resort Maldives at Landaa Giraavaru runs a comprehensive coral propagation project to artificially cultivate corals and to nurture the ailing reefs back to health using coral trays. The 420 coral trays planted since 2006 (when the Resort opened) have shown amazing growth rates. A significant 37,332 fragments of coral have been transplanted at Landaa Giraavaru since the start of the project with a remarkable survival rate of 80%..At Four Seasons Resort Maldives at Kuda Huraa, 198 coral trays have been successfully installed with 18,612 coral fragments transplanted in the waters surrounding the island since 2007..NEWS.Preserving the IslandsÕ Treasures .The results from the experiments and techniques developed at the Resort are also pioneering the global development of artificial reef regeneration. The team of resident marine biologists at the Resort regularly monitors the islandÕs natural coral reefs and by the end of 2008, the coral cover on the resortÕs surrounding reefs has increased by an amazing 20%. Various techniques are being used including artificial reef structures and metal frames to grow coral fragments and facilitate coral transplantation. These new artificially generated reefs attract a multitude of marine life, enabling one to snorkel through a vibrant coral garden again. The ultimate aim of the project is to return the reefs to their pre-1998 condition before the El Nino event..Guests at the Resort are offered the opportunity to sponsor a coral tray which will fund research and expand the restoration of the islandsÕ coral reefs.
