About the reserve

Cors Goch is Anglesey’s most complete fen basin and is primarily base rich fen sitting within a shallow valley fed with lime rich water from the surrounding land via several springs.  Cors Goch is much more than just a fen and there is associated limestone grassland,  acid grasslands and heath lands, woodland and scrub all forming a mosaic of habitats supporting a wide variety of plants and animals.  The reserve is home to many rare and threatened plants and animals’ species with 10 species of orchid, 15 species of dragonfly and over 19 species of butterfly recorded.
