Abstract

The presence of the Eurasian beaver Castor fiber L. has been recently confirmed with two separated populations in Tuscany (Central Italy) and probably represents the result of an unofficial release. In late spring and summer 2021, seven reliable records of Eurasian beaver have been collected in Umbria and other neighbouring regions, implying that the distribution of this large rodent is even wider than previously reported. In this short work, we updated the distribution of this protected species in Central Italy, by collecting and mapping all the confirmed occurrences. Beavers were proved to be present throughout the Tiber (Tevere) river basin in both provinces of Umbria, and another individual has been road-killed in the Marche region, near the border with Tuscany. Other single signs of presence occurred in Emilia Romagna and Latium. The only hair sample we were able to collect confirmed it as the Eurasian beaver species. No reliable evidence is available on the number of free-ranging beavers in Central Italy, and systematic monitoring is needed. Before any management and conservation action, further data are required concerning distribution range, potential origin, social perception, and the effects on the ecosystems.

意大利中部野生欧亚海狸的分布和遗传分析

欧亚海狸蓖麻纤维L.的存在最近在托斯卡纳(意大利中部)的两个分离种群中得到证实，可能是非官方释放的结果。在2021年春末和夏季，在翁布里亚和其他邻近地区收集了7份欧亚海狸的可靠记录，这意味着这种大型啮齿动物的分布范围比之前报道的还要广。在这个简短的工作中，我们通过收集和绘制所有确认的事件，更新了这个受保护物种在意大利中部的分布。在翁布里亚的两个省，整个台伯河流域都有海狸，在靠近托斯卡纳边境的马尔凯地区，还有一只海狸被公路撞死。其他存在的单一迹象出现在艾米利亚罗马涅和拉提姆。我们唯一能收集到的毛发样本证实它是欧亚海狸。关于意大利中部自由放养的海狸数量没有可靠的证据，需要进行系统的监测。在采取任何管理和保护行动之前，需要进一步收集有关分布范围、潜在来源、社会认知和对生态系统的影响的数据。
