- We present pollen proxy records of the variability in the Indian Summer Monsoon (ISM) precipitation during the last ∼4ka (ka = thousand years ago; Late Holocene) from a lacustrine area of Koriya District in Chhattisgarh (C'garh), (central Indian core monsoon zone [CMZ]), India. The results show that open, mixed tropical, deciduous forest occupied the region under a warm and moderately humid climate probably indicative of moderate monsoon precipitation between ∼3796 and ∼2428 cal yr BP. Subsequently, between ∼2428 and ∼1431 cal yr BP, the forest became dense and succeeded the open, mixed tropical, deciduous forest owing to the prevalence of a warm and relatively more humid climate with increased monsoon precipitation. The forest became less diversified from ∼1431cal yr BP to Present under the regime of a warm and relatively less humid climate with decreased monsoon precipitation.
