Raising Baby Corals for Reef Restoration

Restoring the Florida Keys, one piece at a time. 

Ken Nedimyer has been diving in the Florida Keys for 42 years. He used to make his living collecting tropical fish for the aquarium trade. At first business was good, but then Nedimyer began noticing a disturbing trend. 鈥淭he reefs were dying around me,鈥 he says, 鈥渁nd dead reefs didn鈥檛 have as many fish.鈥 While scientists studied the declines, Nedimyer began devising solutions to help bring back coral.

There are many reasons for coral death. Damage from boats and overfishing are problems, while other corals 鈥渄ie by 1,000 cuts,鈥 Nedimyer says, through an accumulation of assaults from disease, hurricanes, cold winters, hot summers, and the like. , a Washington State University marine ecologist, adds that seemingly innocent activities鈥攍ike buying dried starfish or shell jewelry鈥攃an support destructive activities, too. Since the 1970s about 98 percent of a type of coral species that provides critical structure for reefs has disappeared from Caribbean waters, according to the Acropora Biological Review Team.聽

With ideas borrowed from the aquarium trade, Nedimyer and his daughter started experimenting with methods of growing and mounting corals. From a handful of original specimens, his underwater nursery has since burgeoned to roughly 25,000 corals. Largely fueled by volunteers, Nedimyer鈥檚 nonprofit has transplanted thousands of corals from the nursery out into the reef, and replanted still more fragments of broken ones.聽

鈥淩estoration is an excellent way to try to recover reefs, because naturally they can take a long time to recover,鈥 Tissot says. He emphasizes, though, that removing threats is paramount for success. Nedimyer agrees, saying, 鈥淚t鈥檚 much better to protect what we have than try to rebuild what is broken.鈥澛

For reefs that are broken, restoration can鈥檛 come too soon. The Foundation recently received permission to plant 50,000 corals over the next five years. Nedimyer鈥檚 long-term goal is to reestablish the Keys鈥 historic coral populations, and to get the community involved in the efforts. 鈥淩epairing and replanting reefs can be done,鈥 he says. 鈥淚t鈥檚 just a matter of people deciding to do it.鈥
