Pine Marten Welfare and Recovery in the UK

Key Facts

• Pine martens were reduced to a small Scottish stronghold by the 1950s through trapping and habitat loss
• Welsh and English reintroductions from Scottish and Irish populations have begun successfully since 2015
• They require mature woodland with diverse structure and ample prey: small mammals, birds, fruits, and insects
• Pine martens are legally protected in the UK — persecution, disturbance at dens, and trapping are illegal
• An unexpected benefit: their presence suppresses invasive grey squirrels, allowing red squirrel recovery

Welfare Considerations

Pine marten welfare in the context of reintroduction is complex. Translocation stress is significant — captured animals experience handling, transport, and release into unfamiliar territory. Post-release monitoring shows that establishing home ranges and finding food is challenging in the initial weeks. Individual welfare during the establishment phase requires consideration. Once established, pine martens are resilient and thrive in appropriate habitat. Illegal persecution remains a threat and causes individual suffering. Supporting habitat connectivity and reducing persecution are the highest-impact welfare interventions.

What You Can Do

• Support pine marten reintroduction projects with donations and community engagement
• Provide supplementary food (peanut butter, jam, eggs) if you have confirmed pine martens near your property
• Report any suspected pine marten persecution or illegal trapping to the police wildlife crime unit
• Support mature woodland creation and management in areas supporting or adjacent to marten populations
• Never disturb dens — pine martens using dens in buildings or trees are legally protected
