These two tools contain the same correlations, and are updated every 1–2 years. Available here is the Access database version. This provides details of the correlations between habitats in the EUNIS marine habitat classification with habitats in the JNCC Marine Habitat Classification for Britain and Ireland and also listed habitats from various other classifications (Habitat's Directive Annex I, OSPAR, MCZ habitat FOCI, HPIs, MSFD predominant). The database is accompanied by a user guide. The same correlation tables are also available as a [spreadsheet](https://hub.jncc.gov.uk/assets/62a16757-e0d1-4a29-a98e-948745804aec).

It is updated roughly every 1-2 years in collaboration with all UK statutory nature conservation bodies.
