East Sussex, and its location within the United Kingdom

In England, Sites of Special Scientific Interest (SSSIs) are designated by Natural England, which is responsible for protecting England's natural environment. Designation as an SSSI gives legal protection to the most important wildlife and geological sites. As of March 2019, there are 65 sites designated in East Sussex, 45 of which have been designated for their biological interest, 15 for their geological interest, and 5 for both biological and geological interest.

Six sites are Special Areas of Conservation, two are Special Protection Areas, two are Ramsar sites, twenty are Geological Conservation Review sites, ten are Nature Conservation Review sites, five are national nature reserves, ten are local nature reserves, six are in Areas of Outstanding Natural Beauty, two are on the Register of Historic Parks and Gardens and three contain scheduled monuments. Nine sites are managed by the Sussex Wildlife Trust and one by the Royal Society for the Protection of Birds.

East Sussex is a county in South East England. It is bordered by Kent to the north-east, West Sussex to the west, Surrey to the north and the English Channel to the south. It has an estimated population of 757,600 within an area of 1,795 km2 (443,554.2 acres), therefore making it the 28th largest ceremonial county in the United Kingdom.
