Abstract

Habitat Features of Conservation Importance (FOCI) within the Greater Haig Fras recommended Marine Conservation Zone (rMCZ).

Habitat FOCI for the Greater Haig Fras recommended Marine Conservation Zone (rMCZ)were identified from an updated habitat map (GHGF_20150310_BSH_Draft) [GB001518], resulting from an integrated analysis of acoustic and ground truth survey data collected in 2011, 2012 and 2014 at the Greater Haig Fras (rMCZ).

Lineage
Classification Scheme: FOCI. Associated datasets: GB001518 Currently in draft - awaiting feedback from small holes in dataset picked up in Data Ingestion Protocol. Three habitat FOCI were observed in the ground truth data, namely ‘Subtidal Sands and Gravels’, ‘Mud Habitats in Deep Water’ and ‘Sea-Pen and Burrowing Megafauna Communities’. It was not possible to map ‘Subtidal Sands and Gravels’ due to the inability to separate ‘A5.1 Subtidal coarse sediment’ from ‘A5.4 Subtidal mixed sediments’. The habitat FOCIs ‘Mud Habitats in Deep Water’ and ‘Sea-Pen and Burrowing Megafauna Communities’ were however distinguished from each other by a bathymetric boundary; ‘Sea-Pen and Burrowing Megafauna Communities’ were only observed below the depth of 113 m, and ‘Mud Habitats in Deep Water’ occurred primarily above this depth. The area classified as the BSH ‘A5.3 Subtidal mud’ was split to the habitat FOCIs ‘Mud Habitats in Deep Water’ and ‘Sea-Pen and Burrowing Megafauna Communities’ along the 113 m depth boundary.
