Alde-Ore Estuary


Site overview: This site is on the Suffolk coast in eastern England. It is made up of the estuarine complex of the rivers Alde, Butley and Ore, including Havergate Island and Orfordness. Mud-flats, saltmarsh, saline lagoons and semi-intensified grazing marsh are all found here. A large bed of shingle, known as the Orfordness/Shingle Street landform is in this site, and it is unique within the UK. During winter, birds such as wetland birds including seabirds, wildfowl and waders come here to feed and shelter. This area is especially important because several species of seabird, wader and raptor nest here.
