Abstract
Phyto-diversity of the forest sites of the Nawada district of Bihar, India was evaluated. A total of 204 species belonging to 171 genera and 63 families were recorded from the district. It includes 55 dicotyledonous families (151genera, 182 species), 6 monocotyledonous families (18 genera, 20 species) and 2 pteridophyte families (2 genera, 2 species). Different biodiversity indices were used for tree, shrubby and herbaceous layers. On the basis of different biodiversity indices, study reveals that in the tree layer, most diverse site was Pichali Upparisar whereas in shrubby and herbaceous layers Tulsiahari Forest and Pachbahni Forest were the most diverse sites respectively. Varied diversity of tree at different sites may be due to disturbances in the area. Dominance of Lantana camara at two sites is a matter of great concern and it may pose heavy problem to other sites in near future. Hence, it is essential to take suitable measures to curb its spread. Findings of study will be useful for conservation and judicial utilization of different components of plant diversity of the Nawada district.
