Adjoining areas of urban environment has undergone rapid alteration in structure, composition and ecological changes, which makes them a dynamic entity. During the present investigation, herbaceous vegetation were studied in east, west, north and south directions of Ambikapur township at various seasons during March 2017 to April 2018. A total of 18 species representing 11 families were recorded at various directions of Ambikapur township in different seasons. Asteraceae was the predominant family in the study area. Highest species counts were recorded during summer season. Among the herbaceous vegetation, more than two-thirds of the herb species were exotic in nature, revealing the anthropogenic role towards loss of indigenous species. Highest species density was recorded in north direction (152,000 herb/ha during rainy, 104,000 herb/ha in winter and 184,000 herb/ha in summer) and lowest in south direction (90,000 herb/ha during rainy, 72,000 herb/ha in winter and 88,000 herb/ha in summer) in all seasons. Higher Shannon diversity (2.71 in rainy, 2.69 in winter and 3.07 in summer) and richness (0.67 in rainy, 0.52 in winter and 0.66 in summer after west direction) were recorded in the north direction. Total biomass, C storage and CO₂ mitigation were found to be highest towards north direction in all seasons. Argemone mexicana, Cassia tora, Ocimum tenuiflorum and Sida acuata are the most suitable species in terms of C storage, CO₂ mitigation under urban setup. Beside, some weed species also reflected significant potential. CO₂ mitigation by herb species can act as complimentary system towards climate cane adaptation beside other vegetal layers. Such studies are also very much effective towards development of greenery in an urban setup leading to climate mitigation process.
