CEND0915 cruise report: Baseline monitoring at Haig Fras candidate Special Area of Conservation/Site of Community Importance and East of Haig Fras Marine Conservation Zone.

 

Abstract

 
During May 2015, a survey was carried out from RV Cefas Endeavour at Haig Fras candidate Special Area of Conservation (cSAC) and Site of Community Importance (SCI) and East of Haig Fras Marine Conservation Zone (MCZ). The primary aim of the survey was to collect data to provide a baseline for Type 1 monitoring of these sites.
 
Haig Fras cSAC/SCI encompasses the majority of an isolated, fully submarine bedrock outcrop located in the Celtic Sea, 95km north west of the Isles of Scilly and covers 481km2. The bedrock outcrop is the only substantial area of rocky reef in the Celtic Sea beyond the coastal margin. It supports a variety of fauna ranging from jewel anemones and Devonshire cup corals near the peak of the outcrop to encrusting sponges, crinoids and Ross coral towards the base of the rock (where boulders surround its edge) (Rees 2000).
 
The rock is granite, mostly smooth with occasional fissures. The rocky outcrop is approximately 45km long and in one area rises to a peak which lies just 40m beneath the sea surface (Rees 2000). The surrounding seabed is approximately 117m deep. The site was proposed for designation due to the presence of EC Habitats Directive Annex I Reefs. Conservation objectives set out the desired state for the protected features of a Marine Protected Area (MPA) (JNCC 2012).
 
East of Haig Fras MCZ is located in UK offshore waters of the Celtic Sea between the UK and the Republic of Ireland. The site is approximately 70km from the Land’s End peninsula, south west England and covers an area of 409 km2. The seabed is heterogeneous, with small patches of substrata blending into each other. Ridges composed of a mosaic of coarse and mixed subtidal sediments run through the site. These sediment ridges are topped with rocky features and are separated by sand or mud.
