A diverse saltmarsh flora, extensive reedbeds (Phragmites) and dune systems are present alongside grazing-marshes that hold a rich diversity of aquatic plant species. The site is also of great geomorphological interest. The IBA is important for a variety of breeding species, wintering wildfowl and migrating waders.
