A site in the Bristol Channel, proposed to the Society as a breeding place for scarce creatures, primarily birds. Today, it is noted for its special geology – the sea cliff exposures provide an insight into the Triassic period (200 million years ago) when the area was a beach between a desert and a marine lagoon. The area is also important for overwintering wading birds. A Site of Special Scientific Interest (SSSI), Sully Island is now privately owned.
