Structure and Composition of Vegetation in Balikpapan Bay Mangrove Forest and their Implication for Conservation

Mangrove forest has the great significance function in protecting the ecosystem balance. Balikpapan bay dominated by mangrove forest is now facing the pressure from the community and industrial activity that endanger the sustainability of the ecosystem. The objective of this study was to explore the plant species including tree, sapling and seedling of the mangrove forest at Balikpapan Bay, East Kalimantan. Data were collected from the plots established on study site and analyzed descriptively-quantitatively using Importance Value Index (IVI). The result showed that Rhizophora apiculata was dominant in all plant stages. In tree stage R.apiculata was dominant with IVI = 177,63% followed by Dysoxylumsp (41,29%) andSonneratia alba (38,54%). In the sapling stage R. apiculata was dominant with IVI =
167,74%.S. alba(IVI = 35,32%) and Rhizophoramucronata(IVI = 34,93%)were the secondly and thirdly dominant species respectively in the sapling stage. In the seedling stage R.apiculata also was dominat with IVI = 81.63%.Mangrove trees mostly found in the diameter range of 21-40 cm, and trees with the height of 10 – 20 m dominatedthe area of Balikpapan bay mangrove forest. Result showed that the regeneration of the mangrove forest was not normal and endanger. It affected the wildlife of the mangrove ecosystem. The abundance of plant species in the sapling stage could ensure the sustainability of Balikpapan Bay mangrove forest, including flora and fauna conservation in the mangrove forest ecosystem. Conservation strategies need to be implemented to ensure the sustainability of mangrove ecosystem.
