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.
