Restoration of Posidonia oceanica
Phase 4:

Restoration of Posidonia oceanica

Posidonia oceanica is a marine plant endemic to the Mediterranean Sea. Unlike algae, it has a root, stem and leaves. It blooms in Autumn, giving rise to fruits known as sea olives.

It forms extensive meadows that constitute one of the most outstanding ecosystems in the Mediterranean. It performs important functions, such as habitat for many species, protecting beaches against erosion and capturing CO2, helping to mitigate climate change.

It is currently in regression due to marine pollution, sand dredging and extraction, the anchoring of boats and fishing practices such as trawling.

The main objective of this project is the restoration of Posidonia oceanica meadows through “pilot replanting” in small selected areas, based on their ecological importance.

Said plantations will be carried out in a non invasive manner, planting in quadrants with seedlings from seed collection and cultivation and / or collection of bundles from natural fragmentation.

At a later date, a detailed monitoring of the specimens and the recovery of the meadow will be carried out, evaluating and determining the survival rate and the degree of growth of the transplanted specimens, as well as the recovery of the ecosystem in general.
