Belizean biologist revives storm-damaged coral reefs

In 2001, Hurricane Iris damaged coral reefs off the coast of southern Belize, inspiring marine biologist Lisa Carne to begin a restoration project.

After the storm reduced coral cover at Laughing Bird Caye National Park to under 6%, Carne started researching how to replant broken coral fragments, building on techniques developed by coral-restoration specialist Austin Bowden-Kerby. Carne founded Fragments of Hope, an organisation that now operates more than 23 underwater coral nurseries.

The group grows coral fragments on structures like metal frames and cement bases before transplanting them to damaged reefs at over 10 locations across Belize, including Laughing Bird Caye, Gladden Spit, and Turneffe Atoll. Fragments of Hope has outplanted over 100,000 corals and also involves local fishers and tour guides in the restoration process.

A United Nations Development Programme report showed that coral cover at Laughing Bird Caye increased from less than 6% to over 50% by 2017, providing habitat for marine life and supporting coastal communities. Carne’s work demonstrates a path to restoring reefs facing ongoing threats like hurricanes and warming seas.
