Abstract

The paper discusses the results of pollen analytical investigations of Late-Quaternary deposits from Khajiar Lake in Himachal Pradesh.

At about 2000 B.C. the vegetational history begins with the predominance of oak woods. The oak woods along with some associated elements remain dominant throughout the pollen sequence except for a temporary decline which corresponds to the rise in elm and walnut and dates to 150 A.D. This change is perhaps suggestive of deforestation. Oak woods again declined at about 700 A.D. and were replaced by deodar. This change in vegetation is attributed to the biotic factor.
