| Summary: | The question of dynamics of forest cover is considered .The reasons are windstorms, forest fi res, outbreaks of mass reproduction of pests, as well as forest management. The purpose of this work is to analyze the loss of forest cover and its restoration using the tools of the University of Maryland, carried out in the framework of the Global forest watch project. The global forest watch project is the best known forest monitoring resource existing since 1997. The data on changes in forest cover area for the beginning of the XXI century for the Tomsk region, which indicate that the loss of forest cover is more than 2 times higher than its growth. The main reason is forest fi res, logging and oil and gas production. At the same time, the greatest losses were recorded on the right Bank of the elevated part of the Ob river, where logging is actively carried out. The dynamics of forest cover in intact forest areas is balanced in the southern taiga, and sharp fl uctuations in the middle subzone, due to large forest fi res that determine the natural dynamics of forests. The infl uence of oil and gas production on the dynamics of forest cover in the case of the creation of infrastructure facilities (pads, roads, etc.) can be equated to the effects of forest fi res and logging. The loss of forests in this case can be more than 3 times higher than the increase. In the case where the activities of the oil and gas sector is limited to exploration with cutting profi les loss of forest cover close to the background. Forest losses in specially protected natural areas are associated with massive outbreaks of forest pests. The main pest is the Ussuri polygraph, which damages fi r forests and its activity is forest-forming in relation to fi r forests. Рассмотрен вопрос динамики лесного покрова в зависимости от причин, которыми являются ветровалы, лесные пожары, вспышки массового размножения вредителей, а также лесопользование. Цель данной работы заключается в проведении выполненного в рамках проекта Глобальной лесной вахты ...
