Mapping of the benthic biotopes in the proposed Sound of Arisaig Special Area of Conservation

SNH commissioned the BioMar project to map the distribution of biotopes and lifeforms in the Sound of Arisaig pSAC, and in addition, undertake further detailed studies of the maerl beds within the site. Video and grab samples were collected, and 12 sites surveyed in detail by diving to collect samples for maerl analysis and characterisation of the biotopes associated with the maerl. 23 biotopes were identified from the video samples and by the MNCR sealochs survey. A map of the predicted biotope distribution based on the acoustic characteristics of the sea bed was prepared for the survey area. Additional information source: Davies, J. & Hall-Spencer, J. (1996).
