Abstract

Quantitative study of forest community characteristics and non-timber product in community forest can enhance effective area management planning. The objective of this study was to investigate the plant community and quantitative characteristics of bamboo in the community forest at Ban Krathum Thong, Wang Khoi sub-district, Paisali district, Nakhon Sawan province. Sixteen, 20x20 m sampling plots were established for data collection and to classify species composition and bamboo quantity. Results showed that 3 sub-communities were classified. First, the Lagerstroemia calyculata sub-community had 29 species with basal area, tree density, and diversity index of 9.83 m2 ha-1, 635 trees ha-1, and 2.81, respectively. Second, the Bombax anceps sub-community showed 32 species with basal area, tree density, and diversity index of 14.71 m2 ha-1, 865 trees ha-1, and 2.74, respectively. Third, Azadirachta indica community had 21 species with basal area, tree density, and diversity index of 13.08 m2 ha-1 and 557 trees ha-1, and 2.32, respectively. Thyrsostachys siamensis was the only bamboo species found in the study area. The mean culm number, DBH, and height were 684.75±401.19 culms rai-1, 6.22±2.55 cm, and 4.75±195.62 m, respectively. The mean shoot number, diameter, and height were 293±205.52 shoots rai-1, 5.41±2.22 cm, and 186.63±99.32 cm, respectively. The evaluated value of bamboo trunk and shoot were 1,156,230.99 Baht rai-1 and 414,559.01 Baht rai-1, respectively. The results indicate that  plant communites in the study sites have different tree species composition and bamboo quantities. Therefore, in management planning, the quantitative data of plant communities should be considered  important.
