Do not anchor on posidonia but on sand.

Reduce individual products, such as sunscreen (use an ecological one), and waste, like paper, bottles, etc.

Become a partner of pro-posidonia associations.


Do not allow anchoring on posidonia, establish laws and surveillance, as well as install ecological anchoring systems and promote protocols of good practices.

Reduce toxic waste from treatment plants, desalination plants and other types of factories.

Establish normatives for water purification.

Control water quality.

Carry out scientific studies on the environmental impact caused by posidonia threats.

Declare protected areas, such as Marine Reserves, National Parks and Natural Parks.

Establish artificial reefs and reforest with rhizomes and/or posidonia seeds.

Develop preservation plans.

Study invasive species.

Map the posidonia zones and sand areas to determine the extent of the posidonia and let the vessels know where they can anchor.

Avert the aquaculture and residual spill points from the meadows.

Sensitize national and international companies and organizations.

Raise populations awareness.

Prevent mass tourism.

Measures currently implemented in Formentera, according to Save Posidonia Project

Regulation with ecological mooring buoys

77 ecological buoys have been installed, 51 in the Bay of Alga on the islet of s’Espalmador and 26 in the Caló de s’Oli. The buoys prevent boats (up to 25 meters) from anchoring and destroying posidonia. It has had a positive reception by the navigators.

Anchorage assistance and surveillance service

In 2013, the Government of the Balearic Islands launched a service in Ses Illetes integrated by guards that provide information and raise awareness to seafarers about the importance of anchoring on sand rather than on posidonia. In addition, they give assistance during the maneuver and supervise that no spills or other harmful activities are generated at sea.

Increase of the surveillance boats fleet for 2017

In 2017, surveillance was increased in the Natural park of ses Salines of Ibiza and Formentera due to the increase of boats.

Proposals from WWF/Adena

Expand the list of places with posidonia presence proposed by the autonomous communities as LIC (Sites of Community Importance) in the Natura 2000 Network.

Investigate, map and regenerate posidonia meadows.

Comply the current legislation and stop threats, monitor and eliminate illegal trawling, establish artificial reefs, prohibit shellfish fishing on meadows, purify wastewater properly, stop industrial spills, control anchoring areas and execute the protocols of the Barcelona Convention and accept the remaining ones.

Analyze the feasibility and environmental impact of coastal constructions and limit them as much as possible.

Establish protected areas at sea that consider the entire ecosystem and not only the fishing resources.
