Threatened coral get second chance in South Florida

They were once in danger of dying off, but efforts to restore South Florida's coral reefs are paying off. A Nova Southeastern University team for two years has been growing staghorn coral in nurseries and then planting it off the Lauderdale-by-the-Sea coastline. So far, they've planted more than 2,500 coral colonies, hoping the coral will spawn on its own and the colonies will expand. At one location, the number of surrounding coral already has quadrupled.
