Some forest formations have adapted to regular pyrogenic impacts and, if the impact of fire does not exceed a certain limit, it does not entail any serious consequences for ecosystems. As a possible criterion for evaluating the effectiveness of forest fire services, prevention of the level of burnout beyond a certain standard can act. The previously known methodology for assessing the annual rate of permissible forest burnout (developed within the framework of the FLEG II - ENPI Vostok regional program in 2016) requires a detailed consideration of each forest site. This requires detailed data on specific sites, which makes it impossible to use data from the State Forest Register of the Russian Federation. Within the framework of the proposed study, a modified version of this technique is proposed. In this variant, the data of areas and stands on these areas are used. The key approach has also been preserved, when the age of felling (for the corresponding forest-forming breed) is taken as the basis for the period of the forest-forming process, taking into account the precautionary factor. At the same time, the division of territories by forest fire zones was carried out according to a simplified (in comparison with the original methodology) algorithm with the division of forest-occupied lands into three zones (4 in the original methodology). All reserve forests and young trees in operational forests are assigned to zone A. Other operational forests are assigned to zone B. All protective forests are assigned to zone C. The data obtained during the calculations help to determine the approximate area of fires for each region of Russia. This area can be taken as "normal", and based on it, evaluate various activities in the forest, for example, such as extinguishing forest fires, reforestation and others.
