Across the Argosaronic region, and within the framework of its marine-focused strategy, AEF supports the generation of scientific knowledge and evidence on critical Posidonia oceanica and other seagrass ecosystems.
In collaboration with specialised scientific institutions and local stakeholders, the Foundation contributes to the collection of field data and the improved mapping of these largely invisible, yet ecologically vital underwater systems in selected areas of interest. This approach combines technical surveying with dialogue and field-based knowledge from fishers, divers, local authorities and coastal communities.
Rather than pursuing blanket mapping of the entire region, the focus is on addressing specific knowledge gaps where spatial evidence is most needed. Over time, these targeted efforts build a growing body of locally grounded data, strengthening the foundation for informed conservation and marine governance.
As of 2026, we have mapped more than 650 hectares of Posidonia oceanica meadows across Spetses, Hydra, Poros, Methana, and the Argolic Gulf.
