The paper investigates changes in the species structure of forests over a 20-year period (2001-2020) for the zone of the alleged flooding of the Nizhneboguchanskaya HPP and adjacent areas using geographic information systems and Earth remote sensing data. Areas of forest destroyed as a result of felling and fires were identified. The paper gives a quantitative estimation of these changes. A map of the dominant tree species for the study area was obtained. The satellite imagery of medium spatial resolution (Sentinel, Landsat) was used as the initial data, as well as information products Burned Area and Forest Cover Loss of the University of Maryland based on satellite data and field research data. It was found that the number of coniferous plantations in the study area decreases. On the contrary, the proportion of non-forested areas as well as deciduous species increases.
