Abstract

Species richness, species composition, height, diameter class structure and tree species diversity were examined in a 1 plot in lowland tropical rain forest in Sungai Lalang forest reserve, Selangor, Malaysia. However, some of trees with diameter of breast height (DBH) of 5 cm and above were measured and recorded to be analyzed.
