Tiwoho mangrove forest islocated in north coast of North Sulawesi province.This area functions as life buffer system for community and sustainability of Bunaken National Park. Due to the important and strategic roles of mangrove in protection and ecological functions, therefore, it is needed to know scientific information about mangrove population dynamics. This research aims to know the vegetation composition and structure vegetation of Tiwoho mangrove forest. Data collection used 20x20 m sample plots that were sistematically laid from the sea to the land side up to the highest tidal line. Distance between plots along 25 m. Results showed that at tree level Sonneratia alba had the highest Important Value Index (IVI) of 206,88 % and Brugueira sp of 46,06 %. Although Rhizopora apiculata value is lower than Brugueira sp. But the values of relative frequency of these species are almost similar. It means that both species are frequently found in observation plots. Rhizophora apiculata dominate at pole and sapling levels, but frequency of occurance this species is lower than Brugueira sp in pole level.

Abstract. Isroni W, Islamy RA, Musa M, Wijanarko P. 2019. Short Communication: Species composition and density of mangrove forest in Kedawang Village, Pasuruan, East Java. Biodiversitas 20: 1688-1692. Mangrove is one of ecosystems located in estuary and shallow coastal waters and its existence has a significant role for life. The aim of this study was to identify species composition and density of mangrove forest in Kedawang village, Nguling Sub-district, Pasuruan District, East Java, Indonesia. Survey method using belt transects was carried at three sampling points. Results of this study showed that mangrove vegetation in Kedawang includes five species from three families, namely Avicenniaceae (Avicennia alba and Avicennia marina), Rhizophoraceae (Rhizophora apiculata and Rhizophora mucronata), and Sonneratiace (Sonneratia alba). At sampling point 1, A. alba dominated with a density of 37 individuals/ha at tree level, 380 individuals/ha at pole level and 3100 individuals/ha at stake level. At sampling point 2, the tree level was dominated by A. alba with 142 individuals/ha, while R. mucronata dominated the pole and stake level with 1300 and 1467individuals/ha, respectively. At sampling point 3, the pole and stake level was dominated by A. alba with 167 and 933 individuals/ha respectively, while A. marina dominated the sapling level with 800 individuals/ha. At all stations, the density at stake level is greater than that tree level. Therefore, it is necessary to carry out conservation efforts in the form of protection combined with restoration by enrichment planting at all study locations to increase the diversity and density of mangrove vegetation.

Information on condition and biodiversity of mangrove ecosystem to support a sustainable management of mangrove ecosystem is very important in the coastal region of Eti village, Piru Bay, West Seram, Molluccas. The purposes of this study were to determine the condition and biodiversity of mangrove ecosystem in the village of Eti, Gulf Piru. Filed data collection was conducted in November 2010 using the line transect method. The box size along the transects was made in accordance with its purposes such as 10 x 10 m2 for trees, 5 x 5 m2 for sapling, and 1 x 1 m2 for seed. The distance between the box transect was 25 m. Number of individuals of each species were counted and the diameter at the chest-height was also measured. Results showed that sixteen species were found within ten genera. There were 9 species of tree categories, 10 species of sapling categories, and 8 species of seed categories. The highest density and frequency of occurrence for the three categories was represented by Rhizophora apiculata, while the largest coverage percentage was represented by Sonneratia alba. The highest important value was also represented by Rhizophora apiculata. In general, the condition of mangrove forests in the village of Eti, Piru Bay was still relatively good, but the local community was very active to take advantage of these mangrove forests products such as charcoal, fencing, and wood that they sold every week. Therfore, it is necessary for local government efforts to protect the mangrove ecosystem from destructed activities of the local community.Keywords: mangrove forest, Rhizophora apiculata, Sonneratia alba, Teluk Piru, Molluucas
