R. Saraswathy, M.Z. Rozainah and G. Redzwan

Abstract

A study was conducted to determine diversity and to estimate biomass of selected mangrove trees in 9 study plots on Carey Island, Malaysia. The total number of individual trees recorded was 453 from 16 species of 5 families i.e. Rhizophoraceae, Avicenniaceae, Meliaceae, Sonneratiaceae, and Rubiaceae. Avicennia alba was the most dominant species with an Important Value Index (IVI) of 15.57%. The total basal area of the mangrove trees was 51.30 m2/ha with Rhizophora mucronata making up most of the total value at 12.53 m2/ha.The estimated total biomass in this study was 51452.85 kg/ha (51.45 tonnes/ha) with the highest contribution from Rhizophora apiculata and Rhizophora mucronata.
