An analysis of the shift of the northern boundaries of closed evergreen coniferous (EGC) stands in Siberia was carried out based on the time series of vegetation cover maps (2001-2016) obtained from MODIS satellite imagery data. The northern boundaries of the EGC for two studied periods (2001-2003 and 2014-2016) were identified. Mostly, a shift of the EGC boundary in the north direction (by ~26±2 km) was revealed. An increase in the area of the closed EGC stands (by 15-50 %) contributed to the expansion of their boundaries was not uniform depending on the relief. In Western Siberia, the increase mainly was observed at altitudes of 100-130 m above sea level, and on the Central Siberian plateau - at 350-500 m. The EGC boundary locates in the zone of mean summer temperatures 12-15 °C. In the study area in 1970-2000s, a warming period was observed (temperatures increased by ~0.5-1.5 °C, p < 0.05). The given temperature regimes facilitated an increase of closure of the EGC stands (by ~1-3 %/year), their expansion to the north, and upward along the elevation gradient. In the zone of intensive anthropogenic impact (oil and gas fields of the Vankor cluster and the Yamalo-Nenets Autonomous Area), a shift of the EGC boundary to the south was observed. © 2020 Space Research Institute of the Russian Academy of Sciences.
