The article presents the results of assessing the restoration of a pine forest on a test site in the vicinity of Ulan-Ude after the 2003 fire and reforestation work. The studies were carried out on the basis of the full polarimetric information of the L-band ALOS-2 PALSAR-2 from 2017–2019. and NDVI indices based on the optical range of Resurs-P and Landsat 1995–2021. The results of the polarimetric decomposition of the H-F-a-classification indicate significant differences between the test and reference forest areas. Studies of long-term seasonal fluctuations of the NDVI for the test site revealed differences in the rate of recovery of multi-seasonal tracks to the pre-fire level and the level of the reference forest areas.
