The peculiarity of bears behavior of stripping of bark is typical for all species. We have described the damage to trees, by Asiatic black bear and brown bear in Primorsky Krai and by brown bears on the Sakhalin Island during 1998-2015. In this study, we studied the damaged bark of the tree only in cases where it was clear that part of the cambium was eaten by bears. Cambium of species is the most preferred for bear consumption in Primorsky Krai. We distinguished very large seasonal fluctuations in the amount of its consumption. The greatest interest of bears in this kind of food is in the summer time. We have analyzed the composition of the cambium of . These results suggest that the important purpose of the use of this kind of food is to restore and maintain the normal functioning of the intestines.
熊剥树皮行为的特殊性在所有熊种中都很典型。我们已经描述了1998 - 2015年期间，滨海边疆区的亚洲黑熊和棕熊以及萨哈林岛的棕熊对树木造成的损害。在本研究中，我们仅在明确部分形成层被熊吃掉的情况下，研究了树木受损的树皮。在滨海边疆区，[树种名称]的形成层是熊最喜爱的食物。我们发现其消耗量存在非常大的季节性波动。熊对这类食物的最大兴趣在夏季。我们分析了[树种名称]形成层的成分。这些结果表明，食用这类食物的一个重要目的是恢复和维持肠道的正常功能。
