Initiated in 2013, the Grenada Artificial Reef Project employs concrete blocks to foster marine life habitats. Remarkable progress was observed shortly after, with algae and various invertebrates flourishing on the structures. However, while research shows these artificial reefs attract species typical of natural environments, further studies are essential to evaluate their role in aiding natural reef recovery and assessing their long-term effects on adjacent ecosystems.
