Marine Habitat Correlation Tables: EUNIS and UK Classifications

Correlation tables linking marine habitats across multiple classification systems, including EUNIS and the JNCC Marine Habitat Classification for Britain and Ireland. The Joint Nature Conservation Committee maintains these tables, which are updated every 1–2 years. The 2018.01 version is archived, with a newer 2026.01 version available.

Use Cases

• Cross-reference marine habitats for conservation reporting based on the listed Habitats Directive Annex I and OSPAR classifications.
• Standardize habitat data from different sources based on the correlations between EUNIS and the JNCC Marine Habitat Classification.
• Support Marine Protected Area (MPA) designation and monitoring based on the MCZ habitat FOCI and HPIs classifications mentioned.
• Analyze biodiversity patterns by translating habitat records between different regional and international classification schemes.

Strengths

• Correlates habitats across at least six distinct international and regional classification systems.
• Maintained with a documented update cycle of every 1–2 years.
• Provided in both spreadsheet and database formats for different user needs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The specific version described (2018.01) is archived, indicating it is not the most current release.
