ABSTRACT
Many researchers around the world show interest in forest ecosystems. Because the growth of forest stands depends on many environmental factors, forest stands can serve as study objects in research on climatic conditions and their role in forest architecture regulation. This study seeks to determine taxation indices of different tree stands to establish the possibility of forecasting the further course of forest development. The study sample includes forest stands with trees of different bonitet classes in the Leningrad region. The results show that climatic and other factors affect trees in different ways, depending on their species, age and location. The estimated height of pine in bonitet class II-IV is lower than the tabular one. The estimated diameter is higher than the tabular one in all cases except for one where stands consist of pine in bonitet class I. The biomass increment was smaller than expected in spruce trees of class III bonitet, pine trees of class II bonitet, and birch trees of class I bonitet.
