It’s around about now that there’s usually the first mention of wolves,” says Gareth Doherty. “Or beavers. In fact, usually both.” We’re in a small hut in the middle of Cropton Forest. It’s late afternoon and with the light starting to fade, Gareth, a forest ranger for the North York Moors National Park, has lit a fire so we can toast a few marshmallows. He can be found here at various times throughout the year, leading twilight and night-time walks through the forest where en route he points out the population of glow-worms and the herd of red deer which generally emerge from the forest at dusk.
