Alpine treeline position in Asian mountains in recent decades either moves upwards in North Asia or demonstrates multi-directional shifts in Himalaya . Since AR5, in North Asia new evidence has appeared of tree expansion into mountain tundra and steppe, of intensive reproduction and increase in tree stands productivity in the past 30-100 years at the upper treeline in the Ural Mountains , in the Russian Altai Mountains  and in the Putorana Mountains . Lower treelines in the southernmost Larix sibirica forests in the Saur Mountains, eastern Kazakhstan, have suffered from increased drought stress in recent decades causing forest regeneration and tree growth decrease, and tree mortality increase . In Jeju Island, Republic of Korea, recent warming has enhanced Quercus mongolica growth at its higher distribution and has led to Abies koreana  growth reduction at all elevations, except the highest locality. Thus, the combination of warming, increasing competition and frequent tropical cyclone disturbances could lead to population decline or even extinction of ABKO at Jeju Island . In the Himalaya, the treeline over recent decades either moves upwards
