Abstract
In the presented paper we used MODIS data to estimate disturbance of forest covered lands in the south-western areas of the Zabaikal Krai caused by fires. Joint analysis of vegetative indices calculated by measurements of the reflected radiation in the near and mid-infrared wave range and data of the on-ground studies allowed to identify areas of successful and poor reforestation on the fire disturbed territories. Based on instrumental data it was found that repeated fires prevented successful reforestation. The analysis of seasonal dynamics indicates that summer fires result in greater damages of forest vegetation as compared to spring fires. Larch stands prevailing in the region account for a major proportion of the fire disturbed lands (including the largest area where the reforestation processes are hampered) while the pine and deciduous stands are characterized by a higher frequency of fires.
