Advice note: Release of pine martens into the wild in Britain

29th January 2015

The pine marten is a medium-sized, arboreal member of the mustelid (stoat and weasel) family. Pine martens were historically widespread throughout Britain but by 1915 the combined effects of woodland clearance and intensive predator control had resulted in extinction in all but the most remote upland areas of northwest Scotland, northern England and Wales.
