Reviving Coastal Reefs: A Collaborative Effort in the Virgin Islands

The Government of the Virgin Islands has partnered with the Association of Reef Keepers (ARK) and Rethink Rebuild Regenerating (rrreefs) to breathe new life into the reefs surrounding the islands.

Rrreefs, an award-winning organisation based in Zurich, Switzerland, is renowned for its mission to revive 1% of coastal coral reefs by 2033. Employing cutting-edge 3D printing technology, they have developed underwater modular clay reef systems that serve as complex habitats conducive to coral recruitment and marine life proliferation.

Marine Biologist and Environmental Officer at the Ministry of Environment, Natural Resources and Climate Change, Ms. Argel Horton, expressed optimism about the innovative approach, stating, “Once it starts thriving, it can be replicated and integrated into our existing reef system so the Territory’s coastal defense can protect us from intense hurricanes, storms, and flooding in our critical low-lying communities.”

The first 3D printed reef, measuring 20 cubic meters, was assembled off Cooper Island at Cistern Rock, a popular snorkeling and dive site. Mr. Christophe Gudin, head of Institute Le Rosey in Switzerland, which facilitated the project, emphasised the importance of marine conservation for future generations, stating, “The changes I have witnessed over the past 20 years underwater and the importance for the next generation of leaders to grasp this fundamental issue has matched remarkably well with this project.”

Over the next two years, ARK will monitor the reef’s impact on marine biodiversity, while Dr. Shannon Gore, Managing Director for ARK, highlighted the critical role of restoration in combating the ongoing threats to coral reefs globally.

“We look forward to seeing how this reef evolves over the coming years and how we can implement more of these types of reefs in the BVI,” said Ms. Marie Griesmar, Co-Founder of Rrreefs, reflecting on the project’s potential for long-term conservation efforts.

Rrreefs has successfully implemented similar projects worldwide, including San Andrés Island, Colombia, where coral recruitment was observed just eight months after installation, demonstrating the efficacy of their approach.
