Extraordinary biodiversity results from “rewilding” an economically-marginal English farm.
Only recently understood: the key role of large herbivores in creating savannah (rather than continuous forest).

Tempted to get the associated book. I wonder what the minimum surface area of land would be for the rewilding process they describe to work. Also, it’d be interesting to compare the same project on different continents and latitudes.
