Sites of special scientific interest: new sites and changes to sites
How Natural England will tell you if your land is selected as a site of special scientific interest, or if there are changes to its designation.
Applies to England
New sites of special scientific interest
Natural England identifies and protects sites of special scientific interest (SSSIs) in England under the Wildlife and Countryside Act 1981 (as amended).
Natural England will select and notify an area as a new site of special scientific interest (SSSI) when it believes the land’s wildlife, geology or landform is of special interest. When land becomes a SSSI, it does not give the public the right to access your land. Natural England will ‘notify’ (or designate) the land as a SSSI.

Sites are selected using the:
Natural England will write to you and tell you if it believes your land has special conservation value. Natural England is likely to callcontact you to discuss this before sending a notification letter.
The letter will explain the legal implications of the notification by including:
- the reasons for designation
- a statement of Natural England’s views on the management of the SSSI
- a list of operations requiring Natural England’s consent
- a map showing the SSSI
- your legal responsibilities
- how to give your opinions or object to the designation
The letter will give you details of an adviser who can help you. They’ll be able to explain:
- what the designation means for you
- what help is available to help you manage your land, such as applying for a grant scheme
You can also read our guidance about:
- managing your SSSI land and getting consent for activities
- public body responsibilities and getting assent for works on SSSIs
Natural England must also tell:
- the local planning authority
- the Secretary of State for Environment, Food and Rural Affairs
- public bodies, such as the Environment Agency, water and sewerage companies and internal drainage boards
Further information on notifying SSSIs can be found on Natural England’s designations programme for areas, sites and trails.
