Description
To study the species composition, stand structure and carbon sequestration of dry zone forest in Minwuntaung Wildlife Sanctuary, sixty sample plots (50x50m) and (30x30m) at three different areas (central, southern and northern) were established and bserved in June 2013. A total of 68 species representing 49 genera and 27 families were recorded in central area, 53 species, 47 genera and 25 families were recorded in southern area and 40 species, 36 genera and 23 families were recorded in northern area. Among the three study area, central area possesses the highest diversity value (H' = 4.50, D = 0.93), southern area has the second highest diversity value (H' = 4.21, D = 0.90), and northern area with the lowest diversity value (H' = 3.66, D = 0.88). As a result of Shannon Wiener evenness (E), the plant species in central area (0.74) were more evenly distributed among the species than the southern area (0.73) and the northern area 0.67. Importance value index (IVI) of major tree species was described by ranking order. Depending on IVI value, ecologically successful species were Terminalia oliveri, Tectona hamiltoniana, Terminalia crenulata, Grewia eriocarpa and Eriolaena candollei. In horizontal structure, ¬¬¬tree density and basal area of gbh (5-15 cm) occurs 1132 n ha-1, 1.29 m2 ha-1 in central area, 1058 n ha-1, 0.97 m2 ha-1 in southern area and 1568 n ha-1, 1.31 m2 ha-1 in northern area. According to Pearson’s correlation, elevation and soil nutrients appear to be the most important factors, which strongly correlated on species diversity, species richness and stem density of the study area. The mean total carbon stocks of tree in central, southern and northern area were estimated 11.92±4.35 ton ha-1, 29.12±5.8 ton ha-1 and 16.38±2.28 ton ha-1.
