Between 2019 and 2021, a team from the Gloucestershire Wildlife Trust trapped 35 wild pine martens in the Scottish Highlands, fitted each one with a radio collar, drove them 600 miles south, and released them into the Forest of Dean, an ancient woodland on the English-Welsh border that had not seen a pine marten in over 160 years. The animals were elusive, nocturnal, and roughly the size of a house cat. Most people in the surrounding communities never saw one. But something in the forest started changing almost immediately.
