Coral reefs around the world have been in decline for decades. Since the 1960s, for example, Florida’s Coral Reef, has lost more than 90 percent of its corals. Recently, researchers have begun to outplant nursery-grown corals in an attempt to restore the reef. Applying a variation of this approach to the slow-growing, reef-supporting mountainous star coral (Orbicella faveolata), we and our colleagues at Mote Marine Laboratory in the Florida Keys were able to achieve sexually mature corals that spawned in just five years.
