NIMF research database

Explanatory Note: BAP & NIMF research database

The Biodiversity Action Plan (BAP) and Nationally Important Marine Features (NIMF) database has been developed from spreadsheets completed by specialists in particular taxonomic groups and by research personnel at the Marine Biological Association for species, and, for biotopes, mainly by research personnel at the Marine Biological Association. The work was undertaken under contract to the Joint Nature Conservation Committee (JNCC) and Department for the Environment Food and Rural Affairs (Defra). However, the database represents the output from a research contract and are not formally endorsed by JNCC or Defra.

The information is presented in its raw form and does not represent a definitive list of species and biotopes for either BAP or NIMF initiatives. The agreed BAP list is available from There is not yet an agreed NIMF list.

The database does not include elasmobranches, which were considered separately by JNCC.

The data are presented here to assist researchers developing action plans and assessing the importance of species and habitats in areas. If there is additional information or if errors are found, please notify the MarLIN team at the Marine Biological Association:
