Abstract:
... Bark stripping by Asian black bears (Ursus thibetanus) has a serious impact on conifer plantations in Japan. Prevention strategies tend to be implemented on a tree-by-tree basis by wrapping standing trees in biodegradable tape or netting. It remains unclear, however, whether installing these materials has a beneficial effect on untreated trees in surrounding stands. The aim of this study was to cl ...

Abstract:
... Bark stripping by Asiatic black bears (Ursus thibetanus) has a serious impact on conifer plantations in Japan, resulting in physical damage to the tree trunks and reduction of the value of the timber. The aim of this study was to clarify whether these plantations are more prone to damage by bears at particular times and sites, to more effectively prevent this damaging behavior. The study was condu ...
