Posidonia oceanica a treasure in Ibiza
Posidonia oceanica, commonly known as Sea Grass, is an angiosperm plant, adapted to underwater life. At first glance it may seem like just another sea plant, but in fact it is an essential part of the Mediterranean marine ecosystem, as it supports many other lifeforms.The meadows of posidonias are the source of the beauty and transparency of the waters of the Pitiusan Sea. Their conservation is therefore essential, as the great biodiversity depend on their strength and vitality.
Posidonia usually grows near the coast in the shallow areas in sandy sea bottoms. This helps to purify the water sediments and keep the seabed and shoreline in place. in other words, it has the same protective function as a coral reef.
Posidonia Oceanica predominates throughout the Mediterranean but in the area of Ibiza and Formentera is probably the biggest protagonist of the sea. Its importance is so great that in 1999 UNESCO conferred World Heritage status on it, the first natural good in the Mediterranean to receive this award recognizing its beauty and uniqueness.
The declaration of Ses Salines of Eivissa and Formentera as a Natural Park in 2001, also marked an important step for its preservation as more than 13,000 hectares of seabed, where the Posidonia Oceanica predominates, were also included within this protection. A curious fact is that within this perimeter, in 2006, one of the most important specimens of this species was discovered, an area over eight kilometers long and 100,000 years old. Recent studies have estimated that Posidonia oceanica meadows can store up to 25 million tons of carbon in the Mediterranean, equivalent to some 90 million tons of CO2, producing the same oxygen of the same area of tropical forest.
