…we will protect you”
With these words Ibiza Cruise Experience wants to explain the importance of the Posidonia and help us all look after it so we will see it dance for many years to come. Posidonia in a marine seagrass only found here in the Mediterranean.
The Posidonia produces 20 liters of oxygen per day per m2 of seagrass, this is the cause of the excellent quality and transparency of our waters.
The Posidonia is a refuge and breeding grounds for a great amount of sea life: fish, octopus, cuttlefish, shellfish …
At the same time Posidonia reinforcess our sea floors and acts as a main protector of our beaches in winter storms preventing erosion through the stratum of the dead leaves that sit on them. We require the continued good health of the Posidonia to maintain and grow our beaches. The disappearance of one meter of seagrass can lead to the disappearance of several meters of beach due to the erosion phenomena of the storms. .
The unique Posidonia only found in the Mediterranean, lives between 1m and 30m deep occupying an area of 3% of the Mediterranean basin which equates to about 38,000 km2, key in the marine species ecosystem.
The Posidonia is being threatened by mismanagement of the environment and the emergence of tropical species accidentally released into the Mediterranean with rapid growth that are gradually replacing the Posidonia. Highlighted threats:
– Contamination, Posidonia is very sensitive to pollutants.
– Malpractice in water sports: Damage due to anchors, oil spills, detergents, paints, solid waste.
– Coastal construction works involving the installation of drains that release sewage into the sea, increasing water turbidity and hindering photosynthesis.
– Construction of dams and other barriers that affect the rate of sedimentation in the sea.
The posidonia prarie represents the highest level of development and complexity that an ecosystem can achieve. It is, therefore, one of the most important ecosystems of the Mediterranean Sea, so which has been classified as “priority habitat”
IBIZA AND FORMENTERA, WORLD HERITAGE
During the 23rd UNESCO World Heritage Committee held in Morocco in 1999, Ibiza, (based on natural and cultural criteria), was declared World Heritage.
Nature – Ibiza’s marine component is characterised by the presence of dense and very well preserved prairies of oceanic Posidonia (seagrass) and coral reefs. The oceanic Posidonia beds at the Marine Reserve are the best preserved beds in the Mediterranean basin. The island’s seabed contains the most diverse community of Cladocora caespitosa, supporting 220 species, the highest record for a marine community in the Mediterranean. This community offers protection to three globally endangered species one being the Mediterranean monk seal.
