Classification des habitats EUNIS 2022

Descriptif de l'habitat

Shingle and cobble beaches formed on dynamic coasts around the Mediterranean and Black Seas, where waves, mostly in winter, weather cliffs and redeposit the eroded material. Mixed with shells and decaying algae and sea grass washed ashore, it provides a nitrogen-rich surface for patchy and sporadic colonisation by annuals and some perennials, also sometimes weedy assemblages. Though widespread, its stands are narrow and localised and highly vulnerable to tourist recreation and coastal development.
