Yellowstone Park is a much-changed place since the reintroduction of the wolf in 1995. Vegetation that had been over-grazed by elk is flourishing, as are populations of animals from beavers to badgers. But there are hunters fearful that the wolves will wipe out all the elk, and ranchers on the park’s fringes who argue that their stock is being terrorised. Nate Blakeslee tells the story in his new book American Wolf (Crown), an extract from which you can read on Literary Hub. It’s a story in which he aims to follow, in novelistic detail, the life of one wolf — O-Six, nicknamed for the year in which she was born. In an interview with National Geographic, Blakeslee tells how O-Six herself fell prey to a hunter.
