| Abstract | The study of relationships existing between plant community characteristics and soil factors can help in furthering the understanding about ecosystem management of community forests. This study aimed to investigate the relationship between the tree species composition and soil factors in the Ban Pong community forest, Long district, Phrae province. Twenty-four sample plots, 20 m x 20 m, size of each were set up using the systematic sampling method to collect tree species composition and soil properties data. Clustering and ordination of the plant community were analyzed using PC-Ord software (version 6) to identify the most significant soil factors affecting the presence of a species. In the sampled plots, 81 species in 63 genera and 26 families were identified, with a Shannon- Wiener index of 3.71. The top five dominant species based on the importance value index were Pterocarpus macrocarpus, Tectona grandis, Xylia xylocarpa, Millettia brandisiana, and Lagerstroemia duperreana, respectively. There were 3 sub-communities of dominant species which included Pterocarpus macrocarpus - Tectona grandis community, which was found on soils with sandy properties, Xylia xylocarpa - Tectona grandis community, which was found on soils with clay and silt texture, and Lagerstroemia duperreana- Erythrina subumbrans community, which did not have any such influences. The results suggest that soil properties are important factors that can determine the distribution characteristics of a plant community. As such, the management of Ban Pong community forest should not focus only on tree species, but on abiotic factors such as variability in soil texture as these may affect the structure of plant community. |
