Analytical and field research of clear cuts conducted within the ForestCom illegal logging program supported by the US Forest Service resulted in the following conclusions: Modern satellite images of Sentinel-2 in their characteristics (spatial and spectral resolutions) are suitable for the identification of rapid changes in forest cover. Their availability (free access) facilitates the increase in the use of inventory and monitoring of the legality of clear cuts. The identification method of forest cover disturbances based on the automatic creation of rapid change maps is the most objective and fast and is therefore the best for implementation in various distant logging monitoring systems. The use of Sentinel-2 images for monitoring of clear cuts is still the most applicable solution, as it, combined with the modern automatic methodology for detecting rapid changes, makes it possible to obtain data on the structure and size of clear cuts over big territories in a short period of time. Such maps of changes in combination with forest owners’ electronic maps and, if available, with schemes of officially conducted loggings, could play a crucial role in detection of illegally logged places and monitoring of other disturbances. Identification of the rapid changes is carried out by comparing individual images for the beginning and end of specified periods with application of the NDVI method. This classical approach is used due to the fact that disturbances in forest cover, such as logging, lead to a decrease in NDVI values.The aim of this workshop is to present assessed changes in the forest cover of certain areas of the Ukrainian Carpathians. |
