Wild Marten Conservation and Welfare

Pine martens are recovering in Britain after near extinction; their welfare and continued expansion depend on woodland habitat and reduced persecution.

Key Facts

Pine martens were reduced to a tiny Highland Scottish stronghold by the early 20th century.
Range expansion has now reached parts of northern England and Wales through natural recolonisation and reintroduction.
Pine martens are omnivores — they consume voles, squirrels, berries, and birds' eggs depending on season.
Interestingly, pine marten recovery correlates with declining grey squirrel numbers, benefiting red squirrel conservation.
They are protected under Schedule 5 of the Wildlife and Countryside Act 1981.

Welfare Considerations

Pine marten welfare in recovering populations is affected by road collisions, illegal persecution by gamekeepers protecting pheasant rearing, and secondary rodenticide poisoning. Radio-telemetry monitoring of reintroduced individuals allows welfare assessment and early identification of problems. Martens caught in snares and traps intended for other species — an illegal but common occurrence — suffer acute injury and distress. Their ecological relationship with grey squirrels suggests that their welfare and conservation may provide knock-on benefits for red squirrel welfare at landscape scale, illustrating how ecological network thinking can serve individual animal welfare.

What You Can Do

Support the Vincent Wildlife Trust marten reintroduction and monitoring programmes.
Report pine marten sightings to the Mammal Society national survey.
Avoid rodenticide use in areas with known marten populations to prevent secondary poisoning.
Advocate for effective enforcement of wildlife crime laws protecting pine martens.
