Explanation of site status:

  1. Special Areas of Conservation (SACs) are sites that have been adopted by the European Commission and formally designated by the government of each country in whose territory the site lies.
  2. Sites of Community Importance (SCIs) are sites that have been adopted by the European Commission but not yet formally designated by the government of each country.
  3. Candidate SACs (cSACs) are sites that have been submitted to the European Commission, but not yet formally adopted.
Where an extension to a designated SAC or SCI is pending, different parts of the site can have different statuses - so, for example part of the site may be SAC, and the remainder cSAC. In this case the site would only appear once in the table, with the whole site shown as SAC.
