Birch biogeocenosis of the Pre-Volga region of the Republic of Tatarstan
The article presents the results of a study of the floristic diversity and productivity of birch biogeocenoses in the eastern part of the Pre-Volga region of the Republic of Tatarstan. The combination of environmental factors (soil, relief, moisture conditions) determines the formation of 5 types of ecological plants, in which 76 species of herbaceous, shrubby and woody plants have been identified. It is shown that the consequences of the 2010 drought had a negative impact on the state of birch plantations.
