Posidonia meadows provide vital habitats for thousands of marine species

What are seagrass meadows and why do they matter?

Seagrasses are coastal marine ecosystems dominated by flowering vascular plants growing on sandy or muddy seafloors to depths of up to 45 m, bunching together in large areas known as ‘meadows’. Seagrasses are found on most continents. There are seven species in the Mediterranean, five of them native to the region. One of these – the most ecologically significant and widespread – is Posidonia oceanica. It covers more than 20,000 km2 around the Mediterranean coast, an area almost as large as Slovenia.

Despite their importance, and the benefits they provide, Posidonia oceanica meadows face increasing threats from human activities, most notably from vessel anchoring.

Preserving and restoring seagrass meadows isn’t just an ecological mission, it’s a strategic necessity for our future.
