The southern tip of the Celtic Deep is 112km north-west of Trevose Head and the western tip is 84km from the Pembrokeshire coast in Wales.

Important frontal systems occur here during summer indicating its value as an area of high productivity, which is supported by the recording of large aggregations of copepods. Copepods are essential for the health of the marine food web and contribute to the diet of the second largest fish in the world, the basking shark.

Celtic Deep is an important aggregation area for seabirds and common dolphins. One of the largest ever known gatherings of fin whales in British waters was recently observed here!

StatusThis recommended Marine Conservation Zone is under consideration for the second tranche of MCZs.

Defra have indicated that this site is now under consideration for tranche two and will potentially be included in the formal consultation at the beginning of 2015. Defra will now working to verify the evidence base for this site and will be looking to engage with stakeholders on both a local and national level to refine information about the site. If designated, it would represent the second largest area of subtidal mud in the region. Intense levels of human activity within the site has resulted in Celtic Deep being classified as at risk by Natural England and the Joint Nature Conservation Committee- there is a high risk that the habitats and species found in this site are currently damaged or deteriorated.

We need you to urge Defra to gather this information as soon as possible and to consider designation of this site as an urgent and high priority for designation in the future.
