Pine Marten Ecology and Conservation in Britain

Pine martens are recovering in Scotland and parts of England and Wales after decades of persecution, with emerging evidence of positive effects on grey squirrel populations.

Key Facts

Pine martens were reduced to a small Scottish population by the early 20th century
They have naturally expanded southward and been reintroduced to Wales and England
Research shows that grey squirrels decline significantly in areas where pine martens are present
Pine martens are largely arboreal and require mature woodland with den sites
They are legal protected species under the Wildlife and Countryside Act 1981

Welfare Considerations

Pine marten welfare was severely compromised during the period of intensive persecution when trapping, poisoning and shooting eliminated them from most of Britain. Individual animals caught in traps suffer acute stress and injuries. Current recovery relies on legal protection and habitat availability, with welfare threats now primarily from illegal persecution, traffic mortality and habitat fragmentation. Reintroduction programmes involve careful welfare consideration during capture, transport and soft-release.

What You Can Do

Support pine marten conservation and reintroduction programmes
Report any suspected illegal persecution of pine martens to wildlife crime officers
