We’re excited to share our latest scientific report, which brings together data from all our reef sites into one comprehensive document.

Scientific monitoring is at the core of every rrreefs project. Our aim is to track and quantify how biological communities develop on our structures in a transparent, traceable, and empirical way. This not only allows us to demonstrate the positive impact of reef regeneration to our partners and enablers, but also provides robust data that can inform policy and help strengthen the protection of vulnerable marine areas.

To achieve this, we work hand in hand with local partners to conduct ecological surveys every six months, for a minimum of three years.

The report highlights the progress of our reefs through four key indicators:

🪸 Coral Recruitment – While natural recruitment varies across space and time, our reefs are showing exceptionally strong results.

🐠 Fish Communities – Fish populations are developing rapidly on our reefs, often faster than expected for artificial structures.

🦀 Invertebrates – Invertebrate communities are flourishing. In Siquijor, diversity and abundance of indicator species exceeded those of nearby natural reefs after only three months.

🧬 eDNA – Environmental DNA helps us detect species that may go unnoticed during standard monitoring dives.

Why this matters
By consolidating data across four different reef sites, this report provides a holistic view of how modular clay reefs can foster biodiversity and resilience under different oceanic conditions. The findings not only strengthen the scientific foundation of our approach but also highlight the potential for scaling reef regeneration globally.

A huge thank you to our dedicated partners, the local communities of Los Ciriales, San Andrés, Pujada Bay and Siquijor, and to all supporters who make this work possible.
