Abstract

Wicaksono FB, Muhdin. 2015. Composition of tree species and standing structure of mangrove forest in the Pasarbanggi Village Rembang, Central Java. Bonorowo Wetlands 5: 55-62. Mangrove ecosystem at the Pasarbanggi village is one of the mangrove ecosystems which is quite good in the northern coastal of Central Java. The tree species that can be found in this mangrove forest is Rhizophora mucronata, Rhizophora apiculata, Sonneratia alba and Avicennia marina. For seedlings dominated by the R. mucronata with Important Value Index 175.99; similarly with saplings and trees are also dominated by R. mucronata with Important Value Index 208.2 and 183.19. Index of biodiversity (H’) in mangrove forests is relatively low, seedlings have a diversity index with a value of only 0.94, while the saplings and trees are only 0.84 and 0.75, respectively. The degradation vulnerability level on density parameters classified as low, while on the biodiversity index parameters of classified as high and tend to degrade Stand structure in general shape of reverse J except for S. alba, that may be caused by unsuccess of regeneration.
