Unmanaged rewilding >of a previously human-controlled environment< indeed decreases biodiversity even further.
The animals required for ensuring a good mix of open woodland, meadows, and forest don't exist anymore. And so, a natural rewilding of such post-human land leads to shrub-dominated flora.
It takes quite a while for this to change into a balanced and diverse flora and fauna.
Longer still for rewilding of a post-civilisation, climate-change_impacted region.
Good writeup of a paywalled paper:

I asked an author for an uploaded PDF so might post a link to that later. https://onlinelibrary.wiley.com/doi/10.1111/ele.70325

The Black Death pandemic from 1347ff is not a blueprint however for what's in store for European post-civilisation landscapes.
The pre-pandemic population of the whole continent was only 60 mio people, that is today's UK population.
So their #landuse was much, much smaller. Forests still were home to wolf packs and bears, one of the prerequisites for a healthy #biodiversity.
Another thing I'd like to get an answer for: how much does the water cycle change with rewilding, ie with shrub-ification?
Will a post-civilisation East-Germany and Poland still turn into dry steppe as projected for >1.5°C?
Or will the shrub-ification counter this climate change impact by increasing cloud-nuclei and rain amounts?
