Pine marten populations in England and Wales are slowly recovering following reintroduction. Understanding their welfare needs and threats supports population management.
Pine martens reintroduced to novel habitats face the challenge of learning landscape-specific food sources and movement routes without the benefit of learned cultural knowledge from established population members. Road mortality is highest in the first year after release as animals explore unfamiliar territory. Wildlife road signage and wildlife crossings in known pine marten movement corridors reduce this welfare impact. Rodenticide use in forestry and farm settings is an ongoing secondary poisoning risk.
