“…Forest fires have become commonplace for many countries with large forests, such as Russia, USA, Canada, Portugal, France, Greece, Turkey, Australia, Tunisia, Argentina, and Brazil [1][2][3][4][5][6][7][8]. The main factors causing a forest fire include climatic conditions (high air temperature, periods with no precipitation, strong winds, low humidity), anthropogenic load (from urbanization, agricultural activities, proximity of megacities, highways, railways, industrial enterprises to forest plantations), and thunderstorm activity [9].…”

In order to predict and assess the danger from crown forest fires, it is necessary to study the thermal degradation of different forest fuels in a high-temperature environment. In this paper, the main characteristics of pyrolysis accompanied by moisture evaporation in a foliage sample of angiosperms (birch) were investigated within conditions typical for a crown forest fire. The heat and mass transfer in the forest fuel element is described by the system of non-stationary non-linear heat conduction equations with corresponding initial and boundary conditions. The considered problem is solved within the framework of the three-dimensional statement by the finite difference method. The locally one-dimensional method was used to solve three-dimensional equations for heat conduction. The simple iteration method was applied to solve nonlinear effects caused by the forest fuel pyrolysis and moisture evaporation. The fourth kind of boundary conditions are applicable at the interface between the sub-areas. Software implementation of the mathematical model is performed in the high-level programming language Delphi in the RAD Studio software. The characteristic changes in the sample temperature field and the phase composition under high-temperature exposure from a forest fire are presented. The induction period of the thermal decomposition of dry organic matter in the sample was determined. Recommendations are made about key features of accounting for the pyrolysis and evaporation processes when predicting forest fire danger. The research results can be used in the development and improvement of systems for predicting forest fire danger and environmental consequences of the forest fires.

“…There is a vast literature on the problems of the Russian forest sector, but only some of them are devoted to modeling (Gordeev, 2018;Glazyrina et al, 2015;Pyzhev, Zander, 2019;Pyzhev et al, 2020). Agent-based models allow to analyze intersectoral interactions (Gulin, Antonov, 2017), econometric models give insight on modeling correlations between regulations and sectoral economic activity (Antonova, 2018).…”

Illegal timber harvesting and trafficking is one of the most important economic and environmental problems in the Russian Federation. Illegal logging leads to degradation of forests and a shortage of timber in wood industries. One of the measures to counter illegal logging is the ban on the export of raw wood, which will take effect on January 1, 2022. However, such a measure will lead not only to control over the circulation of illegal timber, but also to a number of economic consequences. The impact of the ban on the inland market can be assessed using the point sectoral model of the forestry complex (PSM‑fc). The results of scenario calculations show that a ban on the export of raw materials can lead to a reduction in logging volumes and an increase in the share of products of deeper processing in exports

The article assesses the impact of the intensity of selective sanitary cutting in oak forests on the defeat of oak trees by powdery mildew. The research methodology included visual estimation and detailed inspection of oak plantations. On their basis, the species composition of pathogens was identified, the degree of crown desiccation from a complex of factors and leaf infestation with powdery mildew and necrotic spots was assessed. The dispersive analysis was applied for data processing. The analysis of the long-term survey of the plots passed by selective sanitary cutting shows that the degree of damage to oak trees by powdery mildew on permanent test areas practically does not depend directly from selective sanitary cutting, in general, and from their intensity, in particular. The dynamics of the damage degree of the oak trees by powdery mildew changed almost synchronously in all test areas and in the control area. The results can be used in the practice of the Voronezh region forestry enterprises when carrying out forest pathology surveys.
