Abstract

Loss of biodiversity is a threat to the natural ecosystem in any particular area locally and leads to ecological imbalance as a whole globally. So study of the plant biodiversity is an important parameter to understand and assess the population structure. The present paper deals with the population structure and tree species diversity of Ambikapur district, Chhattisgarh state was studied. A total of 110 species belongs to 82 genera and 40 families were recorded. Among these only one family belongs to monocots (Arecaceae). Highest important index value was reported for the species Anogeissus latifolia (8.28) followed by Tamarindus indica (6.65), Ficus religiosa (5.22), Xylia xylocarpa (4.51), Madhuca longifolia (4.47), Terminalia bellerica (4.42), Ficus benghalensis (4.34), Ficus hispida (4.34) Semecarpus anacardium (4.33) and Terminalia chebula (4.23).
