Rationale, Operational approach and criteria, Detailed guidelines for habitats and species groups.
Part Two of the guidelines is being revised.
The Guidelines for the Selection of Biological Sites of Special Scientific Interest (SSSIs) provide a consistent rationale for the evaluation and selection of biological SSSIs throughout Great Britain (the guidelines for the Selection of Geological and Physiographical SSSIs are published separately by JNCC). SSSIs are designated in accordance with the duties in law placed upon each of the country nature conservation bodies (CNCBs) to notify as a SSSI any area of land which, in its opinion, is of special interest by reason of any of its flora, fauna, geological, geomorphological or physiographical features. The Guidelines are intended primarily to help CNCB staff in the selection of biological SSSIs, but are also intended as a public statement of the selection principles for all interested parties.
Part 1 of the Guidelines sets out the general principles from which the evaluation and selection procedures have been developed and explains background issues and concepts. It deals with the broad operational approach and the criteria for SSSI evaluation and selection. Part 2 presents the detailed and specific guidance for each of the main habitat types and species groups.
A revision of Part 2 chapters is underway and as of June 2019 about half of the reviewed chapters have been published and progress is being made with the rest.
The SSSI Biological Guidelines chapters are listed below. Where revisions are underway, the link is to the old version of the guidelines.
