Marine habitat correlation tables version 201801 – spreadsheet version

**The [2026.01 version](https://jncc.gov.uk/resources/ea153999-2892-4c62-919e-c33b33c65fda) of the marine habitat correlation tables is now available on the JNCC website and this version (2018.01) is now archived** Two tools have been created to investigate marine habitat correlations: the correlation spreadsheet and the correlation database. These two tools contain the same correlations, and are updated every 1–2 years. Available here is the spreadsheet 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 (Habitats Directive Annex I, OSPAR, MCZ habitat FOCI, HPIs, MSFD predominant). The spreadsheet is accompanied by a user guide. The same correlation tables are also available in [database form](https://hub.jncc.gov.uk/assets/b9dd7f55-976c-45e9-a9f9-ef93da5a3332).
