Anthropogenic Impact on the Components of the Forest Ecosystem: On the Example of the Bayanaul State National Natural Park.

External anthropogenic factors of influence are: industry, agriculture, hunting and forestry, recreation and other factors, which are responsible for the increasing insularity of most nature reserves. In addition, rural areas have expanded in the last 15 years more than in previous years, indicating a further deterioration of the forest structure and biodiversity of Kazakhstan's important island forests. The study provides a review of research on the study of anthropogenic impact on the components of the forest ecosystem of the Bayanaul forest of Kazakhstan. The degradation of phytocenoses due to the impact of anthropogenic factors has been established. It is shown that the main source of anthropogenic factors is atmospheric air pollution near the highway, forest recreation and the expansion of settlements. In the anthropogenically disturbed areas, soil contamination with heavy metals, a decrease in species diversity, a decrease in projective coverage, and annual growth of Scots pine (Pinus sylvestris L), as well as a decrease in renewable forests over the past 50 years, are noted. The average disturbance of the forest was revealed. Further influence of anthropogenic factors may lead to further deterioration of the forest structure and biodiversity of important natural pine forests of the Kazakh Uplands. [ABSTRACT FROM AUTHOR]
