Pine martens return to Grizedale Forest

The species is an elusive member of the weasel family, evidence from local place names and hunting records suggests they were common in Cumbria until the late 19th century before declining as habitats decreased and they were increasingly hunted as vermin. Now, pine martens are largely only found in Scottish woodland habitats. 

As knowledge of and attitudes towards native wildlife have developed, the importance of pine martens to the wider forest ecosystem is now better understood and celebrated.

Monitoring of pine martens in south Cumbria is well-established, with surveys carried out as part of an exciting partnership project co-ordinated by the University of Cumbria – Back on our Map (BOOM), supported by The National Lottery Heritage Fund. Over the past three years the BOOM team has completed a feasibility study alongside Forestry England, Graythwaite Estate, Cumbria Wildlife Trust and other partners to consider the best approach to restore a healthy, breeding population of pine martens to the south of the county.

Back On Our Map is a project aiming to reintroduce 10 species into South Cumbria with local communities, led by University of Cumbria and Morecambe Bay Partnership.

Ongoing surveys initially provided positive results highlighting extensive suitable woodland habitats to meet the needs of a growing pine marten population.

The team have also been buoyed by positive feedback from the local community.

Ed Sandys, the manager of Graythwaite Estate in the Rusland Valley said: “As a boy, my father remembers black grouse on the fells and red squirrels in all the woodlands. We have lost so much but we are starting to see the return of species through dedicated conservation efforts. We are extremely excited that a pine marten has been seen in our area and must maintain momentum to assist in the recovery of our endangered wildlife."

However, there is still a long way to go to ensure the species is firmly re-established. Mic Mayhew, BOOM Project Officer, said: “Our research shows that pine martens moving south face serious obstacles, including the M6 motorway, and it is likely to be decades before we have a viable breeding population in south Cumbria. The best way to recover populations will involve the release of additional animals trapped under licence in Scotland - known as a translocation.”

To support the next stages of this project, a group of foresters, landowners and conservationists have recently come together to form a working group and develop the next stage of pine marten recovery.

The group has ambitious plans to increase engagement with local communities through public events and to expand native woodland cover through ground-breaking initiatives such as the Restoring Hardknott Forest project in the Duddon Valley. Creating new woodlands and also connecting existing habitats will help benefit pine martens translocated from Scotland and individuals moving south into the county.
