A photograph of the underwater forest of the Posidonia oceanica meadows in the Spanish Ses Salines Natural Reserve (Ibiza) illustrates the Spanish Europa stamp in 2024.
The purity of the Pitiusas waters (Ibiza and Formentera) is a product of the extensive Posidonia meadows and their good state of conservation, favouring the diversity of exceptionally well-preserved biological communities.
Located between the surface level and up to 30-40 meters deep, they occupy large areas of the Mediterranean coast. Unlike algae, they have leaves, stem and roots. They are an endemic species to the Mediterranean Sea that cannot be found anywhere else in the world.
