Лісові ініціативи і cуспільство
In November, the experts of the ForestCom NGO continued to monitor officially recognized and state protected old growth forest areas based on the Sentinel-2 and Sentinel-1 satellite images. However, the constructed composite of 17 Sentinel-2 optical images was unsuitable for monitoring due to heavy clouds (shown in Figure 1).

Therefore, Sentinel-2 radar satellite images were used for analysis (shown in Figure 2).

The total area of 790 plots taken under the monitoring is 11133,7 ha, which is about 66% of the total area of forests accepted for government protection.
Monitoring was performed by visual analysis with the accuracy of the resolution of radar images (15x43 m). Thus, the selective low-intensity logging cannot be determined from such images.
Therefore, based on the analysis, the significant changes in the forest cover were not detected on the inspected area in November 2021.
This NGO “ForestCom” activity is supported by the US Forest Service International Programs.
