A preliminary study on floristic composition of trees in Pelangai forest reserve, Kuala Pilah, Negeri Sembilan

A preliminary study was conducted to determine the floristic composition and community structure of trees in Pelangai Forest Reserve, Kuala Pilah, Negeri Sembilan. Two temporary ecological plots with the dimension of 25 m x 20 m (0.1 ha in total) had been established. The census was carried out for all trees with a diameter at breast height (DBH) of 5.0 cm and above. The floristic composition consisted of 135 individuals from 78 species, 67 genera, and 28 families. The most speciose family was Dipterocarpaceae with eight species, followed by Fabaceae with seven species. The main canopy and understorey species groups recorded the highest number of species and individuals, with 28 and 22 species and 51 and 44 individuals, respectively. Pentace strychnoide are presented the highest total number of individuals for DBH classes of ≥ 5.0 cm, ≥ 10.0 cm and ≥ 15.0 cm. This preliminary study contributed the additional data for logged-over forests in Negeri Sembilan. A detailed study needs to be carried out in the futureto obtain more information on tree species in this forest with a large-sized plot and lower measurement of diameter.
