A sea forest to save the planet

Restoring large-scale degraded marine ecosystems and ensure the recovery of Posidonia Oceanica by planting Posidonia seedlings into meadow areas.


 

Mission

Restoring large-scale degraded marine ecosystems and ensure the recovery of Posidonia Oceanica by planting Posidonia seedlings into meadow areas.

Let’s talk about Posidonia​ 

Posidonia oceanica is endemic to the Mediterranean Sea and the most widespread seagrass species in these waters. Posidonia is a key element for the conservation of Mediterranean ecosystems providing crucial services as: 

  • Regulating ocean acidity (producing oxygen up to 20 l / day per m2)

  • Fixing and sequestrating Carbon (up to 426.6 grams per m2 / year)

  • Sheltering several marine organisms, especially in the juvenile stages (nursery function)

  • Stabilizing seabed through sediment entrapment and damping of wave energy

  • Consolidating sandy coasts against coastal erosion thanks to the accumulation of leaves and rhizomes which form important protective structures (banquettes) 

 

 

Posidonia oceanica meadows experienced an overall declining trend. Between 13% and 38% of seagrass areal extent has been lost since year 1960. These findings urgently call for implementation of management measures aiming at mitigating coastal deterioration on one side and on the other side restoring degraded areas providing a new understanding of reforestation in the marine environment. The Planting activity aims to restore damaged areas of Posidonia oceanica meadows, which are suffering from large-scale regression, often caused by anthropogenic activities, such as free anchoring and illegal trawling. The planting technique chosen by MEDSEA includes the use of Posidonia oceanica plants that are anchored to the natural substrate with the use of small pegs that will be then removed after the formation of new roots. Plants are chosen and collected using exclusively naturally detached collected in neighboring areas, prepared on the surface and then anchored in the mats or in the natural substrate.

Target

Recovery at least 5.000 ha of Posidonia meadow in the Mediterranean sea by 2050.

 

Support our Campaigns

Our actions are supported by organizations that want to make a difference to protect the marine and coastal ecosystem to avoid particularly negative impacts, also by strengthening their resilience, and to act for their restoration in order to obtain healthy and productive oceans

Together with some of them we have carried out concrete projects for the protection of our sea and for the creation of new posidonia forests.

The actions that we will continue to carry out together in the next decade to protect our ocean will affect the future of our planet for centuries to come: we have a huge responsibility towards the planet, towards ourselves and future generations.

It is time for action and together we can still make a difference.
