Bubbling Reef Habitats:Input to the interpretation manual of the marine EUNIS habitats in the Nature Restoration Regulation

This report provides a description of four distinct EUNIS types with bubbling reef habitats, two in the shallower infralittoral zone, one in the deeper circalittoral and one in the offshore circalittoral zones. The report outlines published knowledge on the formation of bubbling reefs and details about characteristic or dominant species for each habitat. This information is based on mapping and monitoring of bubbling reefs in Danish waters, where the majority of known occurrences within European marine areas are found.
