Using EUNIS habitat classification for benthic mapping in European seas: present concerns and future needs

Area of Science:

• Marine Ecology
• Habitat Classification Systems
• Biodiversity Informatics

Background:

• The European Union Nature Information System (EUNIS) provides a standardized habitat classification for Europe.
• Its marine component is crucial for conservation, mapping, and environmental management initiatives across European seas.
• Existing EUNIS marine data coverage is incomplete, and its application reveals further issues requiring resolution.

Purpose of the Study:

• To review the application and identify challenges of the EUNIS marine habitat classification.
• To foster collaboration between scientists and the European Environment Agency (EEA) for EUNIS enhancement.
• To propose improvements for a more accurate and consistent representation of European marine habitats.

Main Methods:

• A workshop organized by the MeshAtlantic project convened experts in EUNIS marine classification.
• Discussions focused on practical experiences, case studies, and identified challenges.
• Recommendations were formulated for the EEA and European Topic Centre on Biological Diversity.

Main Results:

• Challenges in EUNIS marine classification were categorized into five areas: structure/hierarchy, biology, terminology, mapping, and future development.
• Weaknesses in the current classification were identified.
• Proposals for modification and a process for further development of the marine component were outlined.

Conclusions:

• The EUNIS marine habitat classification requires significant enhancements to accurately represent European marine biodiversity.
• Improved collaboration and standardized practices are essential for consistent marine habitat mapping and data reporting.
• A clear roadmap for the future development of the EUNIS marine component is needed to support conservation and management goals.
