Abstract

ABSTRACT In order to determine the species richness, the species composition, height, diameter class structure and tree species diversity were examined in a 1-ha area in lowland tropical rain forest in Sungai Lalang forest reserve, Selangor, Malaysia. However, some of trees with diameter at breast height (DBH) of 5 cm and above were measured and recorded to be analyzed. As a result, all species at the study site were compared with some results which were found equaled abundant according to Evenness Index that gave a value of 0.922; Margalef’s Index reflected a value of 17.01. Chaetocarpus castanocarpus (Euphorbiaceae) was the most important species with an IVI (Important Value Index) of 4.643%, while Euphorbiaceae was the dominant family for the study area with IVI of 14.02%. The study is recommended that this study area should be managed and protected in the right way to ensure the continued existence and conservation of Malaysia natural resource.

ABSTRAK Untuk menganalisis kekayaan hutan, maka komposisi spesies, diameter struktur kelas dan keragaman spesies pohon telah diuji pada sebuah plot di dalam hutan hujan tropis dataran rendah hutan lindung Sungai Lalang, Selangor, Malaysia. Begitu pula beberapa pohon dengan diameter DBH (Diameter Lingkaran Batang ) 5 cm keatas diukur dan dicatat untuk kemudian dianalisis. Sebagai hasil, seluruh spesies pada tempat kajian telah dibandingkan dengan beberapa hasil yang ditemukan melalui persamaan kelimpahan yaitu berdasarkan pada indek kesamaan (Evenness Index) yang memberikan nilai 0.922 ; Indek Margalef memberikan nilai 17.01. Chaetocarpus castanocarpus (Euphorbiaceae) adalah spesies paling penting dengan INP (Indeks Nilai Penting) 4.643%, sementara itu Euphorbiaceae juga merupakan famili paling dominan pada area kajian dengan INP 14.02%. Kajian ini merekomendasikan bahwa area kajian harus di kelola dan dijaga dengan cara yang benar untuk menjamin kelestarian dan pemeliharaan sumber daya alam Malaysia. Keywords: Komposisi spesies, keanekaragaman spesies, Selangor, Malaysia
