Abstract

Results of the study were obtained during the research of pathology the oak woods, collections of intro-duced trees of botanical garden of Voronezh State University. Explore the area about 30 hectares. It was revealed that the woody plants of the botanical garden are exposed to a whole range of natural and anthropogenic factors, which leads to a decrease in the vitality of wood plantings and their ecosystem functions. A significant impact on the wood plantings of botanical garden have the climatic fluctuations of the last decade. To determine the category tree status is taken into account a set of diagnostic features according to the method by V. A. Alekseeva (1989). Condition of the main forest forming breed of Quercusrobur L. it is on average estimated as weakened. Among fund collections and an exposition most depression of wood plantings is noted in the geographical park. Revealed the quarantine a kind of insect pest CamerariaohridellaDeschka et Dimic. The data allowed us to develop a program of sanitary felling of trees from 2014 to 2017, and form the basis of the life condition of these wood plantings.
