This article reflected the results of determining the forest reserve, changes in the forest cover, and factors influencing the forest in the Shariin Gol River Basin, and the study was carried out under the fundamental research project “Ecological monitoring studies of rivers with high risks of human activities (a case study on the Shariin Gol River)". The Shariin Gol River Basin belongs to the Baruun Khentii Khoshuu of the Umnud-Uvur forest region by the Vegetation Region of Mongolia. The forest reserve in the Shariin Gol River Basin covers territories of Orkhon, Khongor, and Shariin Gol soums of Darkhan-Uul province, and Javkhlan, Yeruu, Mandal, and Bayangol soums of the Selenge province, and occupies 109,276 hectares. Natural forest in the basin was mainly dominated by birch forest with an area of 71,423 hectares (80.8%) followed by pine forest with 17 percent coverage, elm forest with 1.4 percent coverage, and the remaining, which included willow, larch, and elm forests. The forest cover map of the basin was mapped using satellite data from 1987 and 2018. In conclusion, the changes in forest cover were associated with forest fires and minings, and a reduction of the forest area, which has been regrowing after being damaged by forest and wildfires, was due to its classification into pasture land in the satellite data.
