The paper addresses long-term phenological trends for the white birch in the central part of European Russia based on multi-year observations of the beginning of the first leaf emergence phase; end of the leaf-fall phase, and vegetation duration for the period of 1976–2015 (the most intense global warming period). Overall, the current global warming affects the timeline of birch phases; however, geographic differences in phenological reactions have been observed. Plants growing in the northern part of the studied area react more actively to the warming in spring: the first leaf emergence phase begins earlier, and the vegetation lasts longer. In the southern part, the earlier spring ‘awakening’ trend has was not detected (trend was zero), while the vegetation duration trend was lower (less than 2.5 days in 10 years) in comparison with the north. Such diverse birch reactions to exterior temperature changes indicate complex relations between the birch phenology and climate.
