Site of Special Scientific Interest or SSSI is a conservation designation denoting the lowest level of protected area in the United Kingdom.
Legal status
SSSIs are defined as any land of special interest because of its fauna, flora, geological or physiographical features.
The designation can be made by English Nature, Scottish Natural Heritage, the Countryside Council for Wales or the Environment and Heritage Service (Northern Ireland).
The legal framework for SSSIs was provided by the Wildlife and Countryside Acts of 1981 and 1985, and the protection of SSSIs was enhanced by the Countryside and Rights of Way Act of 2000.
