【 摘 要 】

In manufacturing environments, the assessment of the state of plantations is carried out mainly by diagnosing trees according to external pathology characteristics. Pathological characteristics which are used in the accepted tree classifications do not satisfy modern requirements, both because of their weak differentiation, and because of their lack of objective explanation. Based on this, a ranking scale of pathological features has been developed depending on their development and fatality for the tree. The category of condition is defined according to the current Forests Code of the Russian Federation for each gradation of the pathological characteristic. As an example, a list of the most significant pathological characteristics for Quercus robur is given, with their gradation in terms of development degree and linkage to the status categories.This list does not include external characteristics that determine the 5 and 6 categories (fresh and old deadwood) because they are more unambiguous, well-descriptive ones and sufficiently described in the current rules.At the same time, a list of pathological characteristics is substantiated and significantly expanded. The presence of these characteristics does not indicate physiological weakening of a tree and, accordingly, can not be the basis for reducing the category of its condition.
