Herm, Jethou and the Humps given Ramsar status
The Channel Islands of Herm and Jethou and the Humps have each been recognised as Ramsar sites.
The islands support a "rich diversity of flora and fauna" while the Humps, rocky islets off Herm, are home to a seal colony.
The Ramsar convention does not offer any legislative protection, but recognises the wetlands to be of international importance.
Environment Minister Yvonne Burford said she was "delighted" by the news.
The Bailiwick of Guernsey already has three Ramsar sites; one at Lihou island and the surrounding area, including L'Eree Headland, in Guernsey, the Gouliot Caves in Sark and Alderney's west coast including the Burhou Islands.
