Developing essential fish habitat maps: report
The project helped define areas of the sea essential to fish for spawning, breeding, feeding, or growth to maturity. Twenty-nine species and multiple life-stages were reviewed covering marine fish and shellfish of commercial and ecological importance, relevant to offshore wind development areas.
Appendix B. List and names of EUNIS habitat types (Level 3 and 4)
Full list of marine EUNIS habitat types considered for the habitat proxy assessment. The list also includes habitats that were excluded a priori from the habitat proxy assessment (highlighted in grey) because considered not relevant to UK inshore areas due to geographical/environmental reasons: N(1), habitats typical of Baltic, Mediterranean, Black Sea or Pontic region; N(2), habitats described as deep offshore or deep sea habitat; N(3), ice-associated habitats.
