This paper presents experience of using geoinformation data in the evaluation of vegetation cover restoration in the pine forests of the Badary tract after the fires that occurred in 2010. This study was preceded by a nine-year period of monitoring observations of the specificity of the species composition of the forest stand, shrub layer and living ground cover in burnt areas and in undamaged forests. The correlation of the generated geobotanical database with the vegetation indices NDVI and EVI obtained from processing medium spatial resolution geoinformation material is considered. The features of the dynamics of the NDVI and EVI indicators were identified both in space and in time. In the burnt areas in the period 2009-2019, a fluctuation of the values of vegetation indices was noted in almost every seasonal group, which correlates with geobotanical parameters that show an upward data dynamics. In forests not affected by fires and, hence, in stable ecological conditions, the NDVI and EVI indicators remained stable or showed a small fluctuation throughout the long-term period. It is noted that NDVI is characterized by an overestimation of values, especially at the peak of vegetation, whereas EVI indicators are more reliable. Multi-temporal analysis showed that both field data and NDVI and EVI indicators show the success of reforestation processes. However, the study of the values of the vegetation indices cannot be considered an independent source of information in the assessment of demutation processes.
