Bear (Ursus arctos) markings of trees in the Chornobyl Biosphere Reserve
For the first time in the Ukrainian Polissia and the Chornobyl Radiation and Ecological Biosphere Reserve (ChREBR), a concentrated linear distribution of bear-marked spruce trees was found at the abandoned estates of the village of Opachychi along the second terrace of the Prypiat River floodplain....
