Genetically Diverse Corals Tested to Save Reefs

Florida scientists are conducting a critical trial to restore elkhorn coral, a vital reef-building species facing significant decline. This initiative involves planting genetically diverse, crossbred "Flonduran" corals—a mix of Florida and Honduran elkhorn—onto wild reefs in Dry Tortugas National Park. The goal is to determine if this enhanced genetic diversity improves the corals' ability to withstand extreme ocean heat, a growing threat.

Researchers are monitoring the growth and survival of these young corals, comparing them to native Florida elkhorn corals. Elkhorn coral plays a crucial role in protecting coastlines by forming reef crests that absorb wave energy. With recent marine heat waves causing severe damage and historical declines of over 95% in Florida Keys populations, this restoration effort offers renewed hope for both the reefs and the coastal communities in Florida and the Caribbean that depend on them.
