Monitoring the colonization of 3D reefs
Research and Development
In 2017, the AMPN submerged 6 artificial reefs weighing 2.5 tons each at a depth of 30 meters, in the heart of the Larvotto Marine Protected Area. Designed through 3D printing using eco-friendly materials, these pioneering reefs faithfully replicate natural habitats to promote the development of marine life.
Since their installation, an annual monitoring of colonization by sessile species (algae, sponges, cnidarians, etc.) has been conducted with the expertise of Thalassa Marine Research and Aquanaute Expertise.
Campaigns carried out between 2017 and 2025 show complete colonization of the reefs, with the presence of rare and protected species such as the spiny cystoseira, which is actually declining in the Mediterranean.
This monitoring also helps understand the impacts of climate change and the increasing frequency of marine heatwaves. Observations indicate that the most sensitive species are gradually being replaced by more tolerant ones.
The first monitoring in 2026 has just concluded, and we hope that future campaigns will continue to confirm the essential role of these reefs in supporting marine biodiversity.
