Abstract

This research aimed to compare the diversity of tree species in conservation and utilization forest areas by specifying 3 sample plots of 20x50 square meters for each area to investigate the number of tree species, which were classified into 3 aged-classes: trees, saplings, and seedlings. The collected tree data were analyzed for the Importance Value Index (IVI) and species diversity index (H') of Shannon-Wiener. The results enumerated 55 species, 45 genera, and 22 families of trees in Ban Hadpudai community forest. The family Fabaceae was the most abundant tree family, followed by Rubiaceae, Bignoniaceae, Combretaceae, and Dipterocarpacceae, respectively. In the conservation forest area 38 species, 32 genera and 16 families were identified. The top 5 tree species with the highest IVI were Shorea siamensis Miq. (38.25%), Xylia xylocarpa (Roxb.) W. Theob. (28.66%), Shorea obtusa Wall. ex Blume (14.07%), Terminalia alata B. Heyne ex Roth (13.50%), and Lannea coromandelica (Houtt.) Merr. (13.37%), respectively. Species diversity indices of trees, saplings, and seedlings age-classes were 1.99 (low), 2.49 (moderate), and 3.06 (high) respectively, whereas 29 species, 22 genera, and 12 families of trees were classified in the utilization forest area. The top 5 tree species with the highest IVI were Shorea siamensis Miq. (62.01%), Shorea obtusa Wall. ex Blume (33.08%), Xylia xylocarpa (Roxb.) W.Theob. (22.61%), Terminalia mucronata Craib & Hutch. (21.00%), and Xantolis cambodiana (Pierre ex Dubard) P. Royen (19.82%), respectively. Species diversity indices of trees, saplings, and seedlings age-classes were 1.45 (very low), 2.55 (moderate), and 2.86 (moderate), respectively.
