Across Asia, under a range of representative concentration pathways  and other scenarios, rising temperatures are expected to contribute to a northward shift of biome boundaries and an upwards shift of mountain treeline . Northward shift and area change of bioclimatic zones in Siberia  and northeast Asia  are projected. Projected changes in vegetation in China at the end of the 21st century reveal that the area covered by cold-dry potential vegetation decreases as the area covered by warm-humid potential vegetation increases . Forest expansion into mountain tundra of the northern Urals is expected . In Republic of Korea, projected under RCP4.5 and RCP8.5 in the 2070s, suitable area loss of six subalpine tree species, namely, Korean fir, Khingan fir, Sargent juniper, Yeddo spruce, Korean yew and Korean arborvitae, range from 17.7 + 20.1% to 65.2 + 34.7%, respectively . Korean fir forests would be replaced by temperate forests at lower elevations, while they would continuously persist at the highest elevations on Mt. Halla, Jeju Island and Republic of Korea . Himalayan birch at its upper distribution boundary either is projected to move upwards  or considered to downslope as a response to global- change-type droughts . Upwards shift in elevation of bioclimatic zones, decreases in area of the highest elevation zones and large expansion of the lower tropical and sub-tropical zones can be expected by the year 2050 throughout the transboundary Kailash Sacred Landscape of China, India and Nepal, and likely within the Himalayan region more generally .
