Why is Posidonia so important for the marine ecosystem?
Posidonia Oceanica is one of the oldest living organisms on the planet, perhaps even dating back 200,000 years. It is a marine plant found in the Mediterranean Sea that forms meadows between the surface and 40 metres deep. Also known as seagrass, it has a vital role in filtering sediments, thus raising the oxygen quality of the underwater ecosystem, and providing food and shelter to hundreds of marine plants and animals including starfish, sea urchins, sponges, sea horses and molluscs.
Posidonia meadows are the lungs of the sea. They absorb enormous amounts of CO2; indeed, about half of the oxygen we breathe is produced underwater. These meadows are responsible for the transparency of the Mediterranean waters and the beauty and biodiversity of their landscapes. During the winter, posidonia protects the beaches and dune areas from erosion, as well as maintaining the quality of the sand. For the last 5 decades, data indicates that between 13% and 40% of seagrasses have been lost. This is an alarming statistic as sea grass grows very slowly, at a rate of just 2cm per year.
It is therefore essential for us all to take urgent action to take care of
posidonia and its marine ecosystem, and
spread awareness among our yachting community in Mediterranean waters.
This concerns us all - if there is not enough green, we cannot enjoy the blue!
Protect our posidonia:
- Know the regulation regarding ecological mooring buoys, assistance services and anchorage surveillance such as those existing in the natural marine parks around the Balearic Islands.
- Sail with navigation charts and use the available apps that indicate restrictions in protected areas where yachts cannot moor and release anchor.
- Always use ecological products on board, both personal items such as soap, shampoo and sunscreen, and eco-friendly cleaning products for the yacht.
- Discharge sewage carefully in designated locations.
- If you are going to fish, use methods that respect the seabed.
- Spread the word and share this post!
