The objective of this study was to identify the characteristic features of trees and shrubs utilized by the European beaver in the Jamy Forest District. A total of 273 trees and shrubs
cut down by beavers were analyzed to identify their species, diameter and distance from the watercourse bank. Tree species which were most frequently felled by beavers were the grey alder, black alder and pedunculate oak. At the three monitored sites, beavers showed a preference for trees with a diameter of up to 15.0 cm. Beavers were most likely to utilize trees and shrubs situated at a distance of up to 15.0 m from the watercourse bank.
