Countryside Council for Wales
Home Page Please note - A new body, Natural Resources Wales has taken over all functions and services previously carried out by Countryside Council for Wales. While the Natural Resources Wales website continues to be developed, some online services will continue to be provided on this web site.


The shallow waters between Holy Island and mainland Anglesey comprise mudflats and sandflats with large areas of seagrass (unusual marine flowering plants) and areas of saltmarsh. These support a wide range of wintering water-birds, especially ringed plover, greenshank, red-breasted merganser and goldeneye. There are areas of rare dune heathland and the whole site supports a range in scarce plants such as sea lavender, dwarf rush and golden samphire.
