Outer Bristol Channel biotopes

Sand and gravel seabeds may at first appear sparsely populated with very few inhabitants. Whilst this is true for very mobile, exposed sands. Digging into the sediment will often expose a wealth of different species. Where solid structures lay on the surface, these will also soon be colonised by a variety of creatures. These structures may themselves be formed by structure building creatures.

During the study, 11 different biotopes were identified. These can be explored using our interactive Biotope map.
