Abundance and Distribution of Cetaceans

Harbour porpoise distribution shifted southward within the Greater North Sea. Abundance appears stable except for a decline in the Irish and Celtic Seas. Assessed populations of coastal bottlenose dolphin appear stable except for a decline in the Sado Estuary. Overall, more frequent large-scale surveys are needed for future quantitative assessment.
