The result of a multidisciplinary field survey of the Haig Fras SAC which was initiated in January and completed during March/April 2011. The current study was initiated to investigate the extent of Annex I reef habitat at Haig Fras. Cefas and JNCC collected full-coverage multibeam bathymetric and backscatter data and associated ground-truthing data. This data has been analysed to update the extent of the Annex I reef and produce a broadscale habitat map. Seven biotopes were identified from drop camera transects with the predominant biotope characterised by Devonshire cup corals, sponges and crustose communities on wave-exposed circalittoral rock. The broadscale habitat map indicates the presence of four main biotopes; high energy circalittoral rock, moderate energy circalittoral rock, deep circalittoral coarse sediment and deep circalittoral sand.
