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.

The diversity of mangrove vegetation is a community that has different characteristics from other communities. Diversity is an important component in mangrove management, but so far the availability of data related to mangroves is still very minimal, including those related to the species diversity of mangrove forest vegetation in the region. This study aims to obtain data on species diversity of vegetation found in the mangrove forest area of Dusun Besar Village, Pulau Maya District, Kayong Utara Regency. Method used was a combination of path and plot method, and the determination of the location and research path location were carried out using purposive sampling. The results of observation and data analysis showed that the dominant vegetation species with the highest importance value index (INP) for seedlings, saplings and trees was the Avicennia marina, namely the INP value of seedlings 37.04%, the INP values of sapling 65.24%, and the value of INP a tree rate of 65. Based on the results of the most dominant analysis found the species of  Avicennia marina with a value of C = 0.03430 for seedling, C = 0.04729 for sapling, and C = 0.04736 for tree level. The diversity of mangrove forest vegetation species in Dusun Besar Village for seedlings, saplings and trees is low because it has an H 'value <1, and the abundance of mangrove vegetation species was not evenly distributed in each forest area because it only has an e value <1.Keywords: Dusun Besar Village, Mangrove Forest, Species Diversity

Mangrove Trees

During the 1996 to 1997, large areas of mangrove forest in the Segara Anakan were cleared and converted into intensive shrimp-ponds. After one to two years, these shrimp-ponds failed and were abandoned. These abandoned ponds created large gap areas and canopy gaps, which were colonized by mangrove shrub and liana. The Segara Anakan mangrove also experienced heavy siltation, and there were tree cuttings from the remnant of the mangrove trees. This research aimed to study the colonization of mangrove vegetation at the abandoned-shrimp pond. Vegetation data were collected using rectangular plots of 25 m x 25 m with 4 replicates. The water qualities were also studied. The results revealed that the mangrove forests were composed of two layers: canopy tree and floor-vegetation. The gap areas triggered the pioneer species of mangrove shrubs and liana, Acanthus ilicifolius and Derris heterophylla, to colonize and dominate 100% of the mangrove forest floor. The mangrove trees consisted of natural and planted tree species. The natural trees were Sonneratia alba, Avicennia alba, and saplings of Aegiceras corniculatum, which  varied between 56 – 136, 4, and 4 individuals per ha, respectively. The planted trees were Rhizophora apiculata, which amounted to 4 – 12 individuals per ha, at the island of the ponds. These trees and saplings were entangled by the liana mangrove, which disturbed their growth. The A. ilicifolius and D. heterophylla prevented the mangrove tree propagules to grow, and they colonized and characterized those abandoned shrimp-ponds, which threatened the Segara Anakan mangrove ecosystem.
