The pine marten in Wales

Pine martens became rare in Wales during the early 20th century but were still in low numbers in parts of the Cambrian Mountains, Carmarthenshire and Snowdonia. However, the population has shown no signs of recovery from its historical decline and is so small as to be vulnerable to extinction. As there was recent evidence of pine martens in parts of Wales, reinforcement was considered a possibility. This means releasing individuals into an existing population, to increase population size and genetic diversity in order to improve population viability.

A feasibility study was carried out to identify several areas in Wales with high habitat suitability for pine martens. Following extensive field surveys, engagement with local communities and stakeholders, and with relevant licences granted, a population reinforcement was carried out.

Between 2015 – 2017, a total of 51 pine martens were captured in Scotland, in areas where there is a healthy pine marten population, under licence from Scottish Natural Heritage. These animals were translocated and released in forestry in mid-Wales. The translocated pine martens are closely monitored, have become established and breeding has occurred each year since the translocation began.
