The IBA comprises sea cliffs, rocky shores and occasional sandy beaches, and covers Kensington Cliffs, Tunnel Beach, Quarry Beach, Curium, and Gibraltar Point. The cliffs contain steep valleys, gorges and caves, and are included within the UK Sovereign Base Area.
Thousands of migrants pass over and frequent the area in spring and autumn.
Pressure/threats to key biodiversity
The IBA falls within a military zone and is inaccessible for the purposes of conducting surveys. This means that it is also inaccessible to hunters, thus reducing the disturbance to birds.
