Pine martens are being reintroduced to English woodlands after centuries of absence, but welfare monitoring during capture, translocation and release is essential for success.
Translocation welfare requires minimising handling time, using appropriate transport conditions, and releasing animals in suitable habitat with adequate prey. Post-release monitoring is critical to identify individuals struggling to adapt. Welfare assessment should continue for at least one year post-release, as animals may face starvation, territorial conflict or predation pressure during establishment. Genetic diversity of founder populations affects long-term viability.
