A decade-long conservation project to restore the fortunes of pine martens across Britain has hit a major milestone.

A collaboration between Vincent Wildlife Trust (VWT) and Forestry and Land Scotland has seen pine martens from the latter’s forests boost populations in Wales, Gloucestershire and Devon - with more than 100 animals successfully translocated.

Dr Jenny MacPherson, principal scientist at VWT, said pine martens were once on the brink of extinction because of habitat loss and historical persecution.
