Version 2026.02. The correlation spreadsheet is currently the only tool publicly available to investigate UK marine habitat correlations. This correlation spreadsheet is updated every 1–2 years.
Available here is the correlation spreadsheet, along with a user guide and a link to the online Marine Habitat Classification for Britain and Ireland. These 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/BSH, HPIs, PMFs, MSFD, Emerald Habitats, Global Ocean Observing System Essential Ocean Variables, VME and Global Ecosystem Typology).
