Analysis of the sanitary state of dendrocenoses of the Chernorechensky forestry of the Orenburg region

Abstract

To prevent environmental damage from the drying out of forests in the Orenburg region, a necessary condition is to conduct constant monitoring of the processes occurring in the forest fund, arising under the influence of external factors, the main task of which is to build an optimal forest management strategy. The complex of factors of negative impact on forest dendrocenoses is not always the same and depends on the diversity of habitat conditions, soil and climatic characteristics of the territories. According to the results of the study, the sanitary condition of the dendrocenoses of the Chernorechensky forestry is assessed as satisfactory; the main reason that worsens the current condition of the existing plantings is the unfavorable factors of the external environment. Since 2020, the spread of bacterial dropsy (pathogen Erwinia multivora Scz.-Parf.) has been recorded in birch plantations, covering an area of 25.8 hectares. The steady increase in the area of forest plantations of “deep” natural poplar ripeness in forestry, as well as in the Orenburg region as a whole, are the main reasons for the decline in the current sanitary condition. At the present stage, there is an urgent need to revise existing legislation, taking into account an individual approach to forestry activities depending on the characteristics of the subject, while it is important to preserve existing forest plantations, especially in sparsely forested areas, which include the Orenburg region.
