Celtic Deep is an important aggregation area for seabirds, common dolphins.
The area is particularly important for its deep water mud habitats, which are rare for this region.
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!
This Marine Conservation Zone has not been included in the second tranche under consultation
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 help ensure that this site is included in tranche 3. Become a Friend of this site to stay up-to-date with The Wildlife Trusts' campaign to see how you can help.
