Abstract
An understanding of the mangrove forest structure is ecologically important, this information useful for the management and sustainable conservation. Aim of this study is to analyze the structure and biodiversity of natural mangrove communities in Sungai Sembilang and Sungai Bungin, Sembilang National Park (SNP). The survey was conducted in September- October 2013. The data was collected by using quadrat of line transect method. The results of the study have a highest density structure in location I was Nypa fruticans Sungai Sembilang and Sungai Bungin which was located on the third location of the same species on the tree level . Seedling density of Rhizophora mucronata highest in Sungai Sembilang at location III and Rhizophora apiculata Sungai Bungin at location I , and seedling of Bruguiera gymnorrhiza in location III Sungai Sembilang and Rhizophora apiculata in Sungai Bungin at location III . The composition of mangrove forests on both the location of the observation that 12 species of mangrove found. Similarity Index of the mangrove vegetation in Sungai Sembilang and Sungai Bungin on trees level, saplings and seedlings respectively 14.2%; 9.3%; and 12.5%.
