A study promoted by Rewilding Apennines in the basins of the Pescara and Aterno rivers has confirmed the presence of at least four Eurasian beavers, which reached the central Apennines following unauthorised releases. The organisation is following this presence with scientific and ecological interest, treating it for what it is: a new phenomenon, to be studied methodically.

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.
