Marloes Mere is a protected wetland area in Pembrokeshire known for its rich biodiversity, particularly rare plant species and diverse birdlife, offering excellent opportunities for nature observation and tranquil walks.
Marloes Mere Site of Special Scientific Interest (SSSI) is a notable wetland habitat situated on the Marloes Peninsula in Pembrokeshire, Wales. This protected area features a shallow natural lake surrounded by marshy reed beds, wet meadows, and a mix of scrub and woodland, creating a vital sanctuary for a broad range of flora and fauna. The mere itself formed in a post-glacial hollow, providing ideal conditions for aquatic plants and species adapted to wetland environments. Ecologically, this site supports several rare and locally important species, including the marsh fritillary butterfly, water vole, and a variety of dragonflies. Birdwatchers frequently visit for sightings of species such as snipe, teal, and reed warblers, especially during the breeding season and migration periods. Beyond its natural importance, the area also has a history of extensive traditional grazing and hay-cutting, which helps maintain the habitat diversity. Visitors can enjoy established footpaths around the mere, allowing for quiet appreciation of the landscape and wildlife without disturbing the sensitive ecosystem. While Marloes Mere does not offer extensive recreational facilities, it appeals primarily to wildlife enthusiasts, photographers, and those seeking peaceful nature walks amid one of Pembrokeshire’s classic wetland settings. Access is typically via minor country lanes, with nearby coastal attractions making it a good complementary stop. The SSSI designation ensures ongoing conservation management to protect its biodiversity and ecological integrity.
