Posidonia Oceanica (commonly known as Mediterranean tapeweed) is an aquatic plant, native to the Mediterranean Sea.

It grows by forming underwater prairies that play a fundamental ecological role in marine and coastal ecosystems.

Specifically, Posidonia prairies house a cluster of biodiversity, hosting numerous species of fish, cephalopods, and crustaceans.

These grasslands are of extraordinary importance for the marine environment as they produce large amounts of oxygen and plant biomass. They also absorb large quantities of carbon dioxide from the atmosphere.

The protective function that Posidonia meadows exert on shorelines is well known since they mitigate damages caused by coastal storms and reduce coastal erosion.

Several activities are threatening Posidonia, including water pollution, the introduction of invasive plant species, coastal works, laying of cables, and marine infrastructure. A further threat is posed by the anchoring of boats and trawling activities.

It is precisely on this front that one of our SeaPartners operates, by mapping and delineating unprotected marine areas covered by Posidonia prairies, which are therefore more vulnerable and endangered due to harmful behaviors and procedures of boats.

By investing in our Seapartner’s activities, you can help protect these delicate ecosystems and the many environmental benefits that come with them.

Where does our Seapartner operate? Activities are currently carried out along the beautiful Catalan Coast.
