Regenerative succession is a natural response of forest ecosystems to economic impact. In forestry practice it is necessary to take into account regularities of regenerative reactions, to predict structural and functional changes in forest ecosystem, to correct regenerative processes, optimizing the solution of economic tasks. A comprehensive study assessed the impact of primary felling and various forest maintenance methods on the state of forest ecosystems: their productivity, sustainability, floristic diversity, the features of anthropogenic impact on the forest environment were studied, the dynamics and mechanisms of restorative reactions were revealed. Measures to improve the practice of economic impact on forest ecosystems were proposed. Particular attention is paid to theoretical aspects of the integrity and sustainability of forest ecosystems.
