The paper considers the dynamics of restoration of plant communities of meadows in the south of Western Siberia according to Sentinel data-2. Four subjects of the Russian Federation and nine specially protected natural territories within them were taken. Sentinel-2 data is characterized by a repetition of the survey once every five days and a spatial resolution of 10-20 m, which allows you to track the moment of the fire with high accuracy and record the state of vegetation before and after it. For quantitative evaluation, we used NDVI and NBR2 indices, which were compared for burnt and unburned areas before the fire, immediately after the fire, one year after the fire and two years after the fire. As a result of statistical analysis by the Mann-Whitney test, it was found out that both indices practically do not show the consequences of meadow fires in any way a year after the fire.
