Abstract :The article presents the results of complex research insert ignore into journalissuearticles values(research was conducted in 2019); of the Botanical natural monument territory “Pine forest near Venetsiya village” insert ignore into journalissuearticles values(Russia);. In 2007, part of the nature monument territory was destroyed by a hurricane, resulting in massive windfall. The purpose of the research was to study the processes of evolution of natural complexes insert ignore into journalissuearticles values(vegetation and soil cover); in the areas affected by the hurricane. Classification of vegetation was done according to the Braun-Blanquet and Kopečký and Hejný approaches. NDVI insert ignore into journalissuearticles values(Normalized Difference Vegetation Index); was used to estimate the amount of photosynthetically active biomass. Changes in morphological, physical and chemical properties were studied in the soil cover. The conducted research showed that the vegetation of the natural monument is represented by relict pine and broad-leaved pine forests. Under the pine canopy linden and birch are dominated. In the herb layer grow in various combinations of nemoral and boreal species. Soil cover is represented by Gray-humus insert ignore into journalissuearticles values(Umbric Luvisol);. There is a strong transformation of vegetation in the areas damaged by the hurricane in 12 years insert ignore into journalissuearticles values(2007-2019);. There is an active formation of highly productive herbaceous vegetation and renewal of deciduous stands, which leads to an increase in biomass insert ignore into journalissuearticles values(confirmed by changes in NDVI);. The terminal stage of the restoration succession will be the formation of secondary deciduous and mixed nemoral forests. The active development of grass vegetation leads to the formation of a sod horizon on the surface of the soil with a thickness of about 14 cm. There is also an increase in the content of organic carbon, alkaline-hydrolyzable nitrogen and mobile phosphorus, the value of electrical resistivity increases and acidification of the soil solution.
