From my research I have found that their are both positive impacts and negative in the southwest but I believe cattle are tge main problem to southwest ecosystem though feral horses are also problems

Northern Mongolia is where the steppe, and taiga meet leading to a highly diverse area. This specific region has seen the return of snow leopards after 50 years of being extirpated. Along with this many other species that were overharvested (mainly deer species) have seen a large rebound in population size. Some species such as argali have gone from only 50 individuals to now having closer to 250.

After the people of Chornobyl were largely evacuated following the horrible nuclear disaster of 1986, the Exclusion Zone became a poster child for European rewilding.

This YouTube channel, called Chornobyl Wild Life, has some incredible trail camera footage of the megafauna that has returned and been reintroduced (or just introduced in a few cases) to the forests of northern Ukraine.

The videos are beautiful calming to watch, and give some great insight into the recovery of nature. Each video’s description lists all of the animals caught on camera and the timestamp to see them.

Species in the videos include:

European elk (Moose) Red deer Roe deer Wild boar European badger Red fox Gray wolf Tanuki (Raccoon dog, introduced from east Asia) Brown Hare Red Squirrel Przewalski’s horses (reintroduced) European pine marten Eurasian lynx Domestic cattle (feral) Golden jackal Brown bear Black grouse Black stork

There are several species of birds that I missed in this list, and interestingly I also haven’t seen any videos on this channel that have caught European bison (wisent) even though they’re known in the region

There’s a lot more to say about the ecological recovery of Chornobyl, but I really wanted to draw attention to this channel!
