They are Back: Notes on the Presence and the life Activities of the Eurasian Beaver (Castor fiber L. 1758) from the Territory of Bulgaria

This scientific note reports on the recently detected presence of the Eurasian beaver (Castor fiber L. 1758) on the territory of Bulgaria. The species was previously a part of the Bulgarian fauna, however it disappeared from the territory of the country more than 150 years ago. Currently, one site in North Bulgaria was an object of long term monitoring and our team was able to detect the life activity of the Eurasian beaver in that particular habitat. The main goal of the present publication is to inform both the scientific community, as well as the public for the presence of the species in Bulgaria, but also to encourage the competent authorities to undertake initiatives for the protection of the species and its habitat.
