Common Seal Welfare Around UK Coasts

Common seals are a familiar UK coastal species whose welfare is affected by human disturbance at haul-out sites, entanglement in fishing gear, and infectious disease.

Key Facts

The UK hosts approximately 40% of the world's common seal population
Common seals regularly haul out on sandbanks and rocks for rest, thermoregulation, and pupping
Disturbance at haul-out sites causes seals to flush into the sea, disrupting rest and pup nursing
Phocine distemper virus caused mass mortality events in 1988 and 2002
Common seals are legally protected but human disturbance remains a significant welfare issue

Welfare Considerations

Common seal welfare at haul-out sites is directly compromised by human disturbance from boats, kayaks, and pedestrians. Seals flushed into the sea during rest periods lose critical thermoregulation opportunities, and mothers separated from pups during nursing may fail to re-establish contact. The cumulative effect of frequent disturbance is chronic stress with measurable physiological consequences. Education and enforceable approach distances at known haul-out sites protect individual welfare. Entanglement in fishing gear causes drowning and injury, making seal-friendly fishing practices a welfare priority.

What You Can Do

Maintain approach distances of at least 100 metres from seal haul-out sites
Report disturbance incidents to the British Divers Marine Life Rescue
Support campaigns for legally enforceable marine wildlife disturbance regulations
Donate to seal rescue organisations providing veterinary care for injured seals
Advocate for seal-friendly fishing practices to reduce entanglement mortality
