Eurasian beaver in Tuscany (Central Italy): the success of unauthorised releases?

Apparently, somebody illegally reintroduced beavers to Central Italy circa 2 years ago.

ABSTRACT
In this short report, we documented the reappearance of the Eurasian beaver Castor fiber L. for the first time in Tuscany (Central Italy). After the detection of unequivocal signs of presence, we confirmed the occurrence of beavers through camera trapping. Genetic analyses (cytochrome-b mitochondrial gene) and hair microstructure confirmed it as the Eurasian species. The reports given here extend the current known range about 530 km south to the known extent of occurrence of this species. The presence of a relict population in this area is almost unlikely, despite being quite far from the nearest village; we therefore may suggest that the individuals occurring in Tuscany may be the result of local unauthorized releases. A precise number of free-ranging beavers remain unknown though at least two individuals are suspected to occur, based on body size. Apart from records of adult individuals, the presence of at least one juvenile suggests that reproduction in the wild may have occurred in 2020. Immediate actions should be promoted to monitor potential expansion, preserve this population, and/or to limit impacts on ecosystems and conflict with human activities.

The article also mentions that beavers are slowly returning on their own to Italy after extinction in 16th century. 2 identified near Austrian border 2018 and 2020. One case on French border this year (not included in this article).

Does Italy need a proper reintroduction project or is it better to be patient and "just" protect those animals that return on their own?
 
More beavers released in Italy:

"In March 2023, other unequivocal presence signs were also detected in southern regions (Molise and Campania), confirming the local presence of beavers. Moreover, two more occurrence sites were recorded in Central Italy (Abruzzi). Despite representing a native species, unauthorised releases of beavers raise management problems, emphasizing the importance of tight monitoring to clarify the actual distribution of this large rodent in these areas."
