Late Holocene vegetation and climatechange in the alpine belt of HimachalPradesh

摘要

Pollen analysis of 1 m deep sediment core from Naych-hudwari Bog, Himachal Pradesh has revealed thataround 1300 to 750 yrs BP, the alpine belt of this re-gion experienced warm and moist climate. The glaciersreceded and the tree-line ascended to higher eleva-tions. Around 750 to 450 yrs BP, intermittent deterio-ration and amelioration of climate have been witnessed.From 450 yrs BP onwards, the glaciers advanced andconsequently the tree-line descended under the impactof cold and dry climate in the region.
