The dynamics of forest fires in the Irkutsk region and its districts was studied. Over the past 30 years, there has been a tendency to increase the area of forest fires covered by fire. Areas with high forest burning were identified. Dynamics of the content of Benzo(a)pyrene in the atmosphere of cities and indicators of fires in the region and its districts are compared. It is established that the content of Benzo(a)pyrene in the air in many cities linearly depends on the area of forest fires. Dynamics of forest fires and the number of hunting fauna in the Irkutsk region districts were studied. With the help of linear correlations, the positive impact of fires on the population of the family of deer ( Cervidae ), canids ( Canidae ), cats ( Felidae ), bears ( Ursidae ) and pheasants ( Phasianidae ), due to one of such factors as the migration of animals from the burning nearby areas, was confirmed. Unstable and negative population dynamics was revealed for the populations of the Kunya family ( Mustelidae ).
