Our "corners" in the Balearic Sea, where we are conducting research and restoration efforts on seagrass replanting.


This is a community-driven seagrass replanting project, focused on investigating innovative techniques and methodologies for restoring seagrass meadows, such as Posidonia oceanica and Cymodocea nodosa, in areas with depths ranging from 0 to 15 metres. We are currently working with six different replanting techniques, four of which have been developed by our scientific team in collaboration with local sculptor Xabier Amonarraiz.

The main objective of this research is to identify the most effective replanting technique(s) so they can be replicated on a larger scale, both in our own projects and those of other initiatives. Furthermore, all the techniques we employ are non-invasive, as we only collect fragments of seagrass meadows that have been naturally detached by events such as storms or human activities like anchoring.

While this is a scientific research project, the involvement of the local community is crucial. For Arrels Marines, ensuring community participation at every stage of the process is key to the project’s success. This is why our seagrass replanting efforts are community-based, with local people taking part in all phases, from fragment collection to restoration, monitoring, and marine stewardship. Additionally, the replanting stations serve as both showcases and underwater laboratories, hosting numerous activities and educational workshops, such as citizen science and scientific diving, organised by our team.

The project’s primary goals are: (1) to develop new tools and techniques for seagrass replanting, (2) to restore areas degraded by human activities, (3) to restore blue carbon sinks, (4) to contribute to the regeneration of the Balearic Sea, and (5) to actively engage the local community through volunteering, workshops, and other participatory activities.

In the spring of 2023, Arrels Marines carried out its first seagrass replanting in the Alcanada area of Alcudia, successfully replanting 320 fragments of Posidonia oceanica, with the participation of over 20 volunteers. A year later, although it is still too early to draw final conclusions, the results are very promising: 85% of the fragments have successfully rooted in the seafloor, demonstrating that the techniques used—some of which had never been tested before—are working!

In 2025, our goal is to advance our research further. To achieve this, we plan to establish a new replanting station in an area with distinct biotic and abiotic conditions compared to Alcanada. This will allow us to compare the results and identify the most optimal conditions for future replanting efforts.
