Table 2.
Average stem density in different land uses and disturbance categories in the protected area (PA), harvested woodland (HW) and traditional agriculture (TA) in Salima District. Same letters within a column of measured attribute indicate no significant difference (p < 0.05). SR = species richness, H = Shannon-Wiener Diversity Index, E = Pielou Equitability Index. ± means Standard error.
