Present study was carried out at Bhoramdeo Wildlife Sanctuary of Chhattisgarh with the objective to assess the composition, structure and diversity of herb layer. Three circle of Kawardha forest division were selected, comprising of three disturbance gradients i.e., heavily disturbed, moderately disturbed and lightly disturbed site, respectively in each circle. Stratified random sampling was opted to measure the herbaceous vegetation. A total of 39, 39 and 33 herbs species were recorded under Bhoramdeo circle, Jamunpani circle and Salehwara circle, respectively. The total density of herbs was varied from 67800-146900 individuals ha−1 in Bhoramdeo circle, 70700-108700 individuals ha−1 in Jamunpani circle and 72000-119200 individuals ha−1 in Salehwara circle. The diversity indices showed that Shannon index value for herb layer in different forest circle along the disturbance gradient varied from 2.50 to 4.25, concentration of dominance (Cd) 0.06 to 0.37, species richness 1.35 to 2.19, equitability 0.76 to 1.34 and beta diversity 1.44 to 2.44. The experimental results clearly indicated that anthropogenic disturbances cause significant impact on ground flora in different circles.
