Four decades on, Chernobyl remains too dangerous for humans. But the wildlife has moved back in. Wolves now prowl the vast no-man’s-land spanning Ukraine and Belarus, and brown bears have returned after more than a century. Populations of lynx, moose, red deer and even free-roaming packs of dogs have rebounded. With human pressure gone, parts of the exclusion zone now resemble European landscapes from centuries past, according to those managing the Chernobyl Radiation and Ecological Biosphere Reserve.
