Edaphic influences on tree species composition and community structure in a tropical watershed forest in peninsular malaysia

A study was conducted to determine tree species composition and community structure, and their relationships with edaphic factors at a watershed forest in Tasik Chini, Peninsular Malaysia. Thirty plots of 0.1 ha were established with a total sampling area of 1.4 ha in inland forest, 0.9 ha in season...

Edaphic influences on tree species composition and community structure in a tropical watershed forest in peninsular malaysia
description A study was conducted to determine tree species composition and community structure, and their relationships with edaphic factors at a watershed forest in Tasik Chini, Peninsular Malaysia. Thirty plots of 0.1 ha were established with a total sampling area of 1.4 ha in inland forest, 0.9 ha in seasonal flood forest and 0.7 ha in riverine forest. A total of 3974 trees with diameter at breast height (dbh) ≥ 5.0 cm were recorded. The inland forest recorded 2061 individuals representing 393 species from 164 genera and 57 families; the seasonal flood forest had 1019 individuals representing 268 species from 137 genera and 57 families; and the riverine forest had 894 individuals representing 260 species from 137 genera and 53 families. Endospermum diadenum (Euphorbiaceae) was the most important species in the inland forest with importance value index (SIVi) of 3.36%, Streblus elongatus (Moraceae) in the seasonal flood forest with SIVi of 4.43% and Aporusa arborea (Euphorbiaceae) in the riverine forest with SIVi of 2.96%.
