The wolves of Yellowstone National Park are perhaps the most recognizable conservation success story in America. Native wolves were exterminated in the park by the 1920s — shot and poisoned as part of official park policy. After decades of conservation campaigns, they were reintroduced in 1995. Since then, they have become a poster child for a sometimes controversial brand of nature conservation called “rewilding” that puts the emphasis on handing the reins over to nature.
