A preliminary study of mangrove distribution at Sg. Haji Dorani, Sabak Bernam, Selangor

Abstract

The objectives of this study was conducted to identify the compositions abundance of mangrove species at Sg. Haji Dorani, which is located at the west coast area of Peninsular Malaysia and to study the species richness, species evenness and species diversity of mangrove ecosystem. Method of inventory that used like recorded the number of species individuals, DBH, height of tree and stem category in each plot. There were 15 plots built over 15 transects along 1 km seaward. Overall, there were mangroves species identified and divided into two types of life form, tree and shrub. By using PC-ORD statistical software version 3.2, species richness, species evenness and species diversity for each species will be known. Avicennia marina showed the highest species richness (15), species evenness (0.947) and species diversity (2.565). Meanwhile, there were six species identified as the lowest species richness, species evenness and species diversity. The species were sapling of Avicennia officinalis, sapling of Hibiscus tiliaceus, sapling of Lumnitzera racemosa, seedling of A.marina, seedling of Excoecaria agallocha and seedling of Hibiscus tiliaceus. However, for overall species at Sg.Haji Dorani, Avicennia marina was the most frequent species found and indirectly dominated the area.
