Seal Sands
Seal Sands is a 294.37 hectare biological Site of Special Scientific Interest in County Durham, England, notified in 1966.
Situated in the mouth of the River Tees next to Greatham Creek and Seaton-on-Tees Channel, the site is accessible from the A178 road running between Seaton Carew and Port Clarence.
SSSIs are designated by Natural England, formerly English Nature, which uses the Metropolitan and [non-metropolitan counties of England|1974–1996 county system]. This means there is no grouping of SSSIs by Stockton-on-Tees unitary authority, or County Durham which is the relevant Ceremonial [counties of England|ceremonial county]. As such Seal Sands is one of 18 SSSIs in the List of [Sites of Special Scientific Interest in Cleveland|Cleveland area of search].
An area of reclaimed land is given over to chemical industries.
