Abstract

Peat fires in drained bogs are now becoming more active and large-scale, which poses a great threat to humans and the environment. The projects for secondary watering of drained zones are difficult and require improved methods for their implementation. Space monitoring is the most effective technique to assess the preliminary results and develop recommendations to further projects for the entire area of the bog. Analysis of remote sensing data since 1970 of the southwestern part of drained Orshinsky moss bog in Tver oblast revealed large areas of open peat after the cessation of their exploitation, which are the most dangerous areas for the occurrence of fire centers. Using NDVI, we found a new water surface increasing by 3,5% and the corresponding increase in vegetation density by 15.6% of the whole area during 2016-2019. Most of the new vegetation is hydrophilous and situated near heavily watered areas. An increase in the water surface shows the general rise in the level of bog waters. At the same time, there is a significant decrease in peat fires, which were not registered after 2015, proving the effectiveness of the implemented projects and requiring further monitoring and observation.
