Abstract

The forest fire influence on the structure and economic characteristics of the forest stand was studied as a part of the research of the Selenga mid-mountain forests. The research tackles the development of forestry paradigms for sustainable development and rational forest management in ecologically important natural areas of the Republic of Buryatia. The purpose of this study was to supplement information about the current state of the forest in the Selenga middle mountains, to study secondary post-fire succession and dark coniferous stands. Research on the natural factors impact on natural regeneration was continued. The influence of forest fires on the structure and economic characteristics of light coniferous plantations of the Selenga mid-mountain forests was conducted. The study of forest plantations in the Selenga mid-mountain makes it possible to understand the processes of forest ecosystems restoration after a fire, as well as to assess the diversity of flora and fauna in these conditions. Burnt forest areas are an important element in the cycle of natural processes, affecting the biodiversity and the dynamics of forest communities. The scientific research on the territory of the Selenga middle mountains makes it possible to identify the adaptation peculiarities of plant and animal species to the conditions of post-fire vegetation and helps to develop measures to protect and restore forests. The study of dark coniferous forests is of crucial importance for assessing their sustainability, self-regeneration ability and conservation of biological diversity, in addition, these studies have a tremendous significance for forest management. The lack of comprehensive information on the state of dark coniferous forests in forested areas makes it difficult to implement rational and environmentally responsible forest management. The accumulated data on the dark coniferous forests of the southern macroslope of the Khamar-Daban mountain range are fragmentary and scattered, so these forests are being properly studied almost for the first time, since their ecology and forestry remain poorly studied, especially under the influence of climatic changes on the ecotone of the light coniferous and dark coniferous taiga. The previously conducted forest management has not been properly summarized and analyzed. The data obtained during the research on the structure, condition, productivity and biodiversity will make it possible to develop forestry measures aimed at preserving the dark coniferous taiga, as well as increasing its sustainability, productivity and efficient exploitation. The study of the forest fires impact on the structure and forestry characteristics of light coniferous forests will allow us to develop recommendations for forestry departments on conducting forestry activities that will help reduce the negative impact of fires on light coniferous plantations and increase their productivity.
