The appearance of small groups of Eurasian beavers (Castor fiber) in various areas of the Italian territory has attracted the attention of the scientific community. The return of this species after more than five hundred years of absence and its ability to change the landscape highlights the potential for coexistence with a wild animal species relatively unknown in Italy.

The white-clawed crayfish, which is a keystone species in freshwater ecosystems, is in decline across much of Europe. A positive feasibility study carried out on streams in the Central Apennines rewilding area means a restocking programme can now be carried out, thereby enhancing the ecological condition of these waterways.
