In winter, hares gnawed the bark of a young cherry, and after a while it turned out that the tree had died. Suggest why and how this happened.

The value of bark for a tree can be compared to the protective role of the skin for humans. When a hare gnaws a cherry, the cambium is damaged, this is a thin layer between the wood and the bark, this is the most important layer in the tree. Even if the damaged area is small, nutritional processes are disturbed, various microorganisms can enter, and the damage process continues. Since this happens in the cold season, often after that the tree simply freezes. A tree that is damaged can quickly dry out, especially a young one, as well as from hypothermia (frost) even with minor damage to the bark, if measures are not taken in time. Unfortunately, many trees do not grow near residential buildings, but for example outside the city, and due to the fact that they did not find damage to the tree in time and did nothing, in the spring they find that it has dried up.
