Proposed Sites of Special Scientific Interest (England)

The Proposed SSSI layer is for internal use only. Anyone using the layer to assess a planning application or to answer an external enquiry should check first with the relevant Land Management team adviser. A Site of Special Scientific Interest (SSSI) is the land notified as an SSSI under the Wildlife and Countryside Act (1981), as amended. SSSI are the finest sites for wildlife and natural features in England, supporting many characteristic, rare and endangered species, habitats and natural features. Boundaries are generally mapped against Ordnance Survey MasterMap.
