In this study, we examined the response forest dynamics (since 1982) on Sokhondo Mountain (2500 m a.s.l.) under climate change in Transbaikalia (southeast of Lake Baikal, Russia) over the last 60 years, using geobotanical and climate long-term monitoring as important tools to assess the effect of climate change on forest dynamics. We found that changes in ecosystems along an altitudinal gradien…
