Abstract: A survey was conducted in the region selecting 6 villages to assess the natural floral composition and its dynamics durring Kharif and Rabi 2013. Sequestration of carbon due to spatial occurrence of flora affected significantly with attaining biomass by plants. The dry matter includes tillers, leaves and flowering parts are directly proportionate to carbon sequestration capacity leading a higher carbon sequestration as 6.37 g in Spaeranthes indicus Linn, 4.75 g in Heliotropium indicum Linn, 6.03 g in Alternanthra sessile (L.) R.Br., 4.85 g in Malva coramendelium (L.) Garcke, 5.18 g in Polygonum hydropiper L. and 4.89 g in Gomphrena celosoides Mart among observed species, which were more than 4 g per plant in nearly 6 months life cycle under natural rainfed ecosystem. Among the narrow leaved flora, Rottboellia exalata L., Iseilema laxum Hack, Echinochloa crusgalli P. Beauv, Aritida ascensionis L., Coix lacrymma-Jobi L., Cyperus defformis L. And Themeda japonica L. stored higher biomass as 3.85, 17.29, 6.65, 4.28, 7.36, 7.41 and 6.65 per plant, respectively over remaining species of terrestrial flora.
