Site description The IBA covers Morecambe Bay and the Lune estuary, with the Leven, Kent, Keer, Lune and Wyre river channels draining through intertidal flats of sand and silt. The whole system is dynamic, with shifting channels formed by the cycle of erosion and accretion. The site also includes important saltmarshes. This area is of outstanding importance for wintering and passage wildfowl and waders, and for breeding wildfowl, gulls and terns.
