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

ABSTRAK
Suatu kajian fitososiologi ke atas flora dan komuniti vegetasi Palaquium gutta (Hook.f.) Baill. telah dijalankan
di petak 13 Hutan Simpan Ayer Hitam, Selangor. Objektif utama kajian
ini ialah untuk mengenal pasti, menciri dan mengelaskan komuniti
P. gutta yang tersebar secara semula jadi di Hutan Simpan
Ayer Hitam. Sejumlah 10 plot (30×30 m) telah dibina mengikut
kaedah transek garisan. Pensampelan vegetasi dan analisis data telah
dilakukan mengikut pendekatan Braun-Blanquet. Keputusan menunjukkan
terdapat 59 spesies dan 54 genus serta 34 famili herba, pokok renek,
pokok lapisan bawah dan juga lapisan pokok kanopi. Spesies paling
kerap dijumpai di kawasan kajian ialah P. gutta dan Endospermum
diadenum (Miq.) Airy Shaw. Kajian fitososiologi telah
mengenal pasti satu komuniti iaitu Palaquium gutta-Endospermum
diadenum ass. nova diikuti dengan dua subkomuniti dikenali sebagai
subkomuniti Dracaena sp. dan subkomuniti Streblus elongatus.
Keputusan juga menunjukkan bahawa kebanyakan spesies adalah daripada
Euphorbiaceae. Ini menunjukkan bahawa hutan tersebut adalah hutan
sekunder.
