MANGROVE FOREST CONDITION IN PIRU BAY, WEST SERAM, MOLUCCAS

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

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.

One important aspect needed in mangrove forest management was the data and information available regarding structure and associations. However, the structure and association of mangrove forests in the Torue watershed downstream had not been identified. The purpose of this research was to evaluate the structure and association of mangrove forests in the Torue watershed downstream. This research used the plot path method with a path and plot combination. Path placement was done by purposive sampling. The results showed that the mangrove forest structure of the Torue watershed downstream consisted of three canopy layers, i.e., Stratum C, D, and E, which were dominated by seedling and sapling growth rates. Stratum C was dominated by Sonneratia alba type, and Stratum D was dominated by Bruguiera gymnorizha and Bruguiera sexangula types. In contrast, Stratum E was dominated by Rhizophora mucronata and Rhizophora apiculata types. There was no association between mangrove vegetation and all species. However, three pairs of species had a positive association coefficient, namely: Sonneratia alba with Rhizophora apiculata with a coefficient value of 0,42, Rhizophora mucronata with Bruguiera gymnorhiza, and Rhizophora mucronata with Bruguiera sexangula each coefficient value of 0,06, which was not associated with five species, namely Sonneratia alba, Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorizha, and Bruguiera sexangula. The results of this study could be the basis of the guidelines for sustainability in mangrove forest management.Keywords: association, mangrove forest, vegetation structure, watershed
