The considerable change of climatic structure of regions of Siberia that started by the middle of the last century and is observed during the last years has inevitably to be reflected on the time course of the forest-steppe contact zone. Estimation of intensity of this process will make it possible to judge about the greatness of climatic changes. In order to clear up the main factors determining the time course of changes of the forest-steppe border, dendrochronological studies were carried out in one of sites of the forest-steppe zone in the territory of West Transbaikalian region. These studies demonstrated that the time course of the border changes in the region studied is to a certain degree associated with the changes of hydrothermal regime.
