Abstract

This research was aimed to know the ecological condition of mangrove forest at various thickness levels and its influence on salinity of fresh water at surrounding area. This research was conducted by analysis of sea water, fresh water, plankton, substrate (soil), and makrobenthos at three location, those were: (1) mangrove with high thickness level (200-300 metre) in Tongke-Tongke Village, (2) mangrove with middle thickness level in Panaikang Village and (3) location without mangrove in Pasimarannu Village. The result of analysis showed that the rate of DO and BOD of seawater in Tongke-Tongke were 5,76 ppm and 1,68 ppm, Panaikang village were 6,48 ppm and 3,63 ppm and Pasimarannu village 6,72 pm and 3,36 ppm. Based on fresh water analysis, the ecosystem of mangrove has significant influence to reduce salinity level. The salinity of fresh water in location with highest thickness level is lowest (Tongke-Tongke is 2.2 ppt) compared to others (Panaikang 2.4 ppt and Pasimarannu 3.2 ppt). The result of substrat analysis showed similar result in which the highest organic substance rate is in Tongke-Tongke followed by Panaikang and Pasimarannu. Abundance of plankton and makrobentos in location with highest thickness level is highest (Tongke-Tongke 210 individu/ml and 849 individu/m2) compared to others (Panaikang is 202 individu/ml and 815 individu/m2 and Pasimarannu village 132 individu/ml and 320 individu/m2)Keywords : Mangrove, ecological condition, thickness level

Abstract

Bird is one of the important species associated with mangrove vegetation. This study aims to determine the diversity of birds in the mangrove areas of Rawa Aopa Watumohai National Park, Indonesia. Observations were done at 12 points for data collection by scanning field by field method. The results revealed that about 54 bird species was found in the surrounding mangrove, eight types of which species was Sulawesi endemic birds and at least three types of which species was migratory birds. The bird species commonly found was Pergam Laut (Ducula bicolor), as many as 63 individuals. Index of bird diversity in the mangrove Rawa Aopa Watumohai National Park was 3.40.Keywords : Diversity, birds, mangrove, Rawa Aopa Watumohai National Park

Abstract

Mangrove forest at Tanakeke Island has important roles both for ecology and economy. High pressure on mangrove caused mangrove degradation in the island. Knowledge of ecological conditions and health of mangrove forest are essential for mangrove ecosystem management at the island. The study aims to determine ecological characteristics and health status of mangrove forest at Tanakeke Island, Takalar District, South Sulawesi. This study employed quantitative methods using field survey with observations using plots of 10 m x 10 m. Observation plots were located evenly all over the island. Results showed mangrove forests at Tanakeke Island consist of 11 species belong to 8 families. Shannon-Wiener diversity index reached 2.01, 1.88, and 1.18 for tree, sapling, and seedling, respectively. Importance Value Index reached 115.31, 172.11, and 108.89 for tree, sapling, and seedling, respectively, and dominated by Rhizophora stylosa at all growth levels. Structure of mangrove forest stands resembles the letter "J" inverted, which means the structure of forest stands were quite normal as a result of the good process of plant regeneration. The density reached 706 ind/ha, 4,824 ind/ha, and 23,382 ind/ha for tree, sapling, and seedling, respectively. In general, mangrove forest health levels at Tanakeke Island were categorized in low to moderate levels.
