The Eurasian beaver (Castor fiber) became extinct in Italy between the end of the 16th century and the beginning of the 17th century. A few animals were recorded at the border with Austria in 2018 and 2020. Between 2021 and 2023, beavers were reported in six Central and Southern Italy areas at more than 350-400 km from the nearest colonies. Following an official position by the Italian Mammal Society, this paper aims to explore the possible origin of these nuclei, suggests their removal and provide an analysis of the concerns and management recommendations. Given the distances between beaver locations in Central and Southern Italy and the rapid appearance of numerous small nuclei with few individuals in just a couple of years, the most plausible explanation is multiple unlawful releases. Unplanned and unauthorised reintroductions are unacceptable in terms of a sound wildlife management approach and represent a dangerous precedent stimulating further unlawful release of mammals. Therefore, we urge competent authorities to remove these animals from the field.

Abstract
The Eurasian beaver (Castor fiber) became extinct in Italy between the end of the 16th century and the beginning of the 17th century. A few animals were recorded at the border with Austria in 2018 and 2020. Between 2021 and 2023, beavers were reported in six Central and Southern Italy areas at more than 350-400 km from the nearest colonies. Following an official position by the Italian Mammal Society, this paper aims to explore the possible origin of these nuclei, suggests their removal and provide an analysis of the concerns and management recommendations. Given the distances between beaver locations in Central and Southern Italy and the rapid appearance of numerous small nuclei with few individuals in just a couple of years, the most plausible explanation is multiple unlawful releases. Unplanned and unauthorised reintroductions are unacceptable in terms of a sound wildlife management approach and represent a dangerous precedent stimulating further unlawful release of mammals. Therefore, we urge competent authorities to remove these animals from the field.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
