Mission: Iconic Reefs
NOAA and partners have launched an unprecedented effort to restore seven ecologically and culturally significant coral reefs within Florida Keys National Marine Sanctuary. Informed by years of research, successful trials, and expertise, the mission represents one of the largest investments ever undertaken in coral restoration. By focusing additional efforts on coral reef habitat, Mission: Iconic Reefs complements NOAA's ongoing Florida Keys National Marine Sanctuary Restoration Blueprint and management plan.
The effort to put Florida Keys coral reefs on track for recovery is an enormous undertaking, requiring long-term collaboration between many partners. A cross-NOAA team is engaging world-renowned scientists, local restoration partners, and other federal and state agencies to save these important, iconic resources.

Divers visit a coral nursery and help clean staghorn and elkhorn coral “tree” structures to remove nuisance algae. Nursery-grown corals are transported to the reef for outplanting. To outplant corals, divers prepare the substrate by removing surface sediment and algae, then affix coral colonies to the reef using marine epoxy. After outplanting, coral fragments grow into mature colonies, contributing to the structure and diversity of Florida Keys National Marine Sanctuary reefs.

Restoration practitioners glue tiny “microfragments” of coral onto ceramic plugs in a land-based nursery. Using this strategy, slow-growing coral species can grow relatively quickly, and can fuse together to form large colonies.

Healthy coral reefs create impressive structures that are home to a vibrant array of fish and other reef creatures, support dive and snorkel tourism, and protect Florida Keys shorelines.

Two divers work together to replant staghorn coral to a reef using epoxy. Marine epoxy is a frequently-used method for adhering nursery-grown corals to reefs.

Fragments of elkhorn coral wait to be attached to the reef at Looe Key. Zoanthids, a type of marine invertebrate that can compete with corals for space, cover much of the surrounding reef area.

Corals grown in a land-based nursery await transplanting. These corals were produced by sexual reproduction (from coral eggs and sperm). This method can help to increase genetic diversity in restored populations.
