A contribution to trees and shrubs checklist in Pelangai Forest Reserve, Kuala Pilah, Negeri Sembilan

Abstract

A preliminary floristic study focusing on a checklist of trees and shrubs in Pelangai Forest Reserve, Negeri Sembilan, was conducted during scientific expeditions in June and December 2023. The expeditions were organised by UiTM Kuala Pilah Campus, Negeri Sembilan, to document the biodiversity of flora and fauna in the forest reserve. Voucher and herbarium specimens were collected along forest trails and within two ecological plots measuring 25 m × 20 m. A total of 165 tree and shrub species, representing 122 genera and 47 families, were recorded. Among these, seven species endemic to Peninsular Malaysia were documented, namely Alphonsea maingayi, Cleistanthus ellipticus, Dendrokingstonia nervosa, Dichapetalum griffithii, Diospyros singaporensis, Pentace strychnoidea, and Ptychopyxis caput-medusae. Further surveys are recommended to provide a more comprehensive inventory of tree species and other flowering plants in Pelangai Forest Reserve.
