Thorness Bay
Thorness Bay is an Site of special scientific interest which is located on the north-west coast of the Isle of Wight, England, in the western arm of the Solent. The site was notified in 1966 for both its biological and geological features. The bay stretches about from Salt Mead Ledge in the west to Gurnard Head Nr. Gurnard Bay to the east.
The boundaries of Thorness Bay SSSI are contiguous with Newton Harbour SSSI and so this protected area is part of a wider area of nature protection.
The sea bed is a mixture of mud, sand and shingle with rocky outcrops of Bembridge Limestone. The soft cliffs of the bay contain the Bembridge Insect Bed, where fossilized plants and insects have been discovered. Over 200 insect species have been recorded in this area.
A small unnamed brook enters the sea in the middle of the bay after passing through a marsh.
Little Thorness Farm, a beef farm near the bay has of protected marshland under stewardship and is a SSSI because it is home to wildlife not found in other areas.
