Research in the Belarussian sector of the exclusion zone found that boar, elk and roe deer populations exploded between 1987 and 1996. By the mid-1990s, wolves were so plentiful they were becoming a nuisance to farmers.

Chernobyl is an honest to god paradise now, like Israel could be if they wanted it to be green and flush with biodiversity.

The radiation there is not good for wildlife, though. What is happening is that the relatively low levels of radiation in the area around the site are not as bad for wildlife as having a lot of humans around was. Having neither humans NOR radiation would be even better, but that is not the deal offered to our lynx and wolf bros.
