The study of species abundance and aboveground biomass for rhizophora-avicennia forest type Tok Bali, Kelantan

Abstract

This study was carried out in the Rhizophora-Avicennia forest type at Tok Bali, Kelantan to determine the species abundance and to estimate the aboveground biomass of mangrove species. About 24 of plots had been built in this area. Classification and feature of the mangrove trees such as type of species, height, crown form and stem category were recorded. All the data must be analyzed by using the suitable formula and PC-ORD statistical program to get the diversity index H'. A total of seven species of mangrove were identified such as Rhizophora apicuiata, Avicennia alba, Ceriops decandra, Bruguiera cylindrica, Bruguiera gymnorrhiza, Sonneratia alba and Dolichandrone spathacea. R. apiculata dominated this study area for adult tree category and for seedling category. C. decandra dominated this study area for sapling category.
