Despite special attention to the protection of forests from fires and fire prevention measures in protected natural areas of federal significance, their distribution is currently of increasing and widespread nature. In this paper, an assessment of the occurrence of the pyrogenic factor in the territory of the Trans-Baikal National Park (TNP) 1987 to 2017 was carried out. The initial data in the study used archival materials TNP on fires. On the territory of the park, the distribution of forest fires over the territory, the conditions of their occurrence and spread were considered. It was revealed that during the period under review the number of fires and their area increased. The climatic conditions of the region have been studied, an increasing number of droughts has been noted, associated both with an increase in air temperature and a decrease in atmospheric humidification. Fires have natural origin on the mainland, and anthropogenic on the Holy Nose peninsula. Different stages of landscape restoration after fires add additional diversity to the landscape structure of the region and often the spread of fires coincides with the dominance in the territorial structure of stable-derived geosystems.
