Lihou Island: A Ramsar Site of International Importance
Designated on 1 March 2006 and covering 427 hectares, this Ramsar site on the west coast of Guernsey is a true natural and cultural treasure. Recognised under the Ramsar Convention, it protects a diverse range of coastal and marine habitats that are internationally important.
What Is a Ramsar Site?
Ramsar sites are part of an international treaty designed to protect wetlands. These wetlands can include marshes, shores, seagrass meadows, and much more. Being listed means Lihou receives special attention for careful management and habitat conservation, and it highlights the island’s importance beyond local borders as a place that supports global biodiversity.
Ramsar Site Details
The Ramsar site, which includes Lihou Island, is made up of several key coastal and marine areas:
- Lihou Island: A small island in the northwest, accessible via a causeway at low tide.
- L’Erée Headland: A coastal area featuring varied terrain, including low rocky outcrops and sandy shores.
- Les Anguillieres: A shingle bank that contributes to the site’s habitat diversity.
- Additional Marine & Coastal Zones: Areas such as La Claire Mare and La Rousse Mare, which support diverse ecological communities.
Why Lihou’s Ramsar Designation Matters
- Diverse Habitats
Lihou’s mix of rocky intertidal zones, grassy slopes, and shingle banks creates homes for countless creatures—from wading birds in winter to colourful seaweeds and rare coastal wildflowers. - Refuge for Wildlife
Many migratory birds rely on Lihou to rest and feed, while the shore’s tidal pools and seagrass beds help fish and invertebrates grow safely. - Cultural Heritage
The medieval priory’s remnants and historical evidence of Mesolithic human occupation remind us of a rich legacy intertwined with the island’s natural splendour. - Protecting Biodiversity
Ramsar designation ensures practical conservation measures—like limiting development and monitoring water quality—so that Lihou’s delicate habitats remain healthy.
Visiting Lihou Responsibly
- Stay on Paths
Following designated routes keeps fragile plants and soils safe from trampling. - No Dogs
Wildlife here can be easily disturbed by pets, so dogs are not allowed on the island. - Tread Lightly
If you explore rockpools, return any stones you move to their original place and avoid collecting living creatures. - Respect Cultural Sites
Enjoy the medieval priory’s ruins from a distance to help preserve this historic structure.
A Special Place to Care For
