Abstract Pollen analysis was carried out from a 23 m core dating from about 30,000 to 9000 yr B.P. from the alpine Tsokar lake about 4572 m above sea level in Ladakh, Trans-Himalayan Region. This study reveals the continuation of the alpine steppe with four periods of expansion of Juniperus communities during 28,000–30,000 yr B.P., 21,000–18,375 yr B.P., slightly before 15,800 yr B.P. and at 10,000 yr B.P. These phases of Juniperus expansion were interpreted as events of amelioration of climate within the alpine steppe during the later part of the last (Weichselian) glaciation in the Alpine Trans-Himalayan Region.
