摘要

A phytosociological study on the flora and vegetation community of Palaquium gutta (Hook.f.) Baill. was carried out in udCompartment 13 of Ayer Hitam Forest Reserve, Selangor. The main objectives of this study were to identify, characterize udand classify the P. gutta community which is naturally distributed in Ayer Hitam Forest Reserve. A total of 10 plots (30×30 udm in size) were constructed according to the line transect method. The vegetation sampling and data analysis were done udaccording to the Braun-Blanquet approach. The results showed that there were 59 species belonging to 54 genera and 34 udfamilies in the form of herbs, shrubs, understorey trees and also canopy tree layers. The most common species in the study udarea were P. gutta and Endospermum diadenum (Miq.) Airy Shaw. The phytosociological study identified a community udof Palaquium gutta-Endospermum. diadenum along with two sub-communities known as Dracaena sp. sub-community udand Streblus elongatus sub-community. The results also showed that most of the species belong to the Euphorbiaceae. udThis indicates that the forest is a secondary forest.
