On the Darwin Core Term dwc:habitat, and the Need to Adopt a European Vocabulary Based on NATURA2000 and EUNIS Classifications, with a Comment on International Applicability

Darwin Core (DwC) is an essential standard for sharing biodiversity data. However, the term dwc:habitat suffers from an inherent ambiguity due to its free-text format. This ambiguity severely compromises the interoperability and reusability of habitat data, hindering large-scale comparative analyses and impeding the formulation of effective conservation policies. As a solution to this problem, we propose adopting controlled vocabularies and ontologies. The NATURA2000 and EUNIS habitat classifications emerge as ideal candidates to standardize dwc:habitat. NATURA2000 offers a consolidated regulatory framework and habitat type definitions with direct implications for European conservation, while EUNIS provides a more comprehensive, hierarchical, and scientifically grounded system with the ability to cross-map with other standards. The implementation of such vocabularies would significantly improve the quality, consistency, interoperability, and reusability of habitat data, more robustly supporting scientific research and conservation policies.
