Abstract
Pollen analysis of 2 m deep sediment core from Kiktiha swamp, Shahdol district has revealed that between 1600 and 700 yr BP, tropical deciduous Sal forests comprising Shorea robusta (Sal), Madhuca indica, Terminalia, Lagerstroemia, Aegle marmelos flourished in the region under a warm and moist climate. Between 700 and 300 yr BP the deciduous Sal forests were succeeded by mixed deciduous forests, which turned sparse and less diversified, reflecting a relatively less moist climate attributed to the weak SW monsoon. The unfavourable climate also adversely affected the agricultural practice as evidenced from the diminution of Cerealia and other culture taxa. Since 300 yr BP onwards the modern deciduous Sal forests were re-established with the timely arrival of active SW monsoon. The increase in Cerealia and culture taxa indicates agricultural prosperity.
