Hong Kong's marine parks face compounding pressure from urban runoff, thermal stress, and sedimentation — conditions that make conventional coral restoration largely ineffective. AFCD required a science-grade solution that could demonstrate measurable biodiversity recovery in a complex regulatory and public environment.
Archireef deployed Reef Tiles across designated marine park sites, paired with eDNA monitoring for non-invasive species detection and photogrammetry to track coral growth over time. A public education component was integrated, leveraging Archireef's visible, accessible restoration infrastructure.
-260% average increase in coral growth during the first 3 years post-deployment
-90%+ coral survivorship over project lifetime
-eDNA monitoring confirmed species return and community recovery
-Established as a model programme for urban marine restoration in high-density environments
