“…famili. Jumlah jenis mangrove yang ditemukan pada penelitian ini lebih tinggi dibandingkan di Teluk Serewe ditemukan 9 spesies (Irwansah et al, 2019).8 spesies di Kecamatan Sekotong (Japa & Santoso, 2019), dan 4 spesies di pesisir Pantai Cemara Selatan Lombok Barat (Janiarta et al, 2021). Namun lebih rendah dibandingkan dengan jumlah spesies di taman wisata alam Bangko-Bangko yaitu sebanyak 12 spesies (Rita, 2015).…”

Mangrove is a type of plant that can survive on muddy substrates and at relatively high levels of water salinity. Information about the ecological value of mangrove is very important, in order to provide an overview of the current condition of mangrove. The purpose of this study is to determine the structure of mangrove community in regional marine conservation area Gili Sulat. This study used quadratic transect method measures are 10 m x 10 m (tree category), 5 m x 5 m (sapling category), 2 m x 2 m (seedling category). Based on the results this study obtained 8 true mangrove species and 2 association mangrove species in regional marine conservation area Gili Sulat. Mangrove species that have the highest frequency value is Rhizophora mucronata (0,57 ind/m²) while the lowest is Avicennia marina (0,03 ind/m²). The density for the tree level is in the rare category, while the sapling and seedling levels are in the very dense category. Bruguiera gymnorrhiza and Rhizophora mucronata species had the highest cover values in the tree and sapling category. The highest INP values in the category of tree, sapling, and seedling were 114,93% (Bruguiera gymnorrhiza), 82,32% (Rhizophora mucronata), and 69,87% (Rhizophora mucronata). Dominance index values are classified as low to moderate and the diversity index obtained is moderate.

“…Rhizophora woods are favored for selective logging, which has a better quality of charcoal and firewood than other mangrove woods (Malik et al 2017). Secondary mangrove forests in Sekotong, Lombok, have grown, ranging from 6.10 to 10.57 cm at average diameters (Japa et al 2019).…”

Abstract. Dharmawan IWE, Renyaan J, Nurdiansah D. 2022. Mangrove zonation, community structure and healthiness in Kei Islands, Maluku, Indonesia. Biodiversitas 23: 4918-4927. Forest structure and quality were studied in an archipelagic site in Indonesia which consists of estuarine and oceanic mangrove habitats. This study aimed to determine mangrove structure and estimate the spatial distribution of forest healthiness along the zones dominated by different genera. Forest zones were investigated using the Random Forest method utilizing a cloud-free Harmonized Sentinel-2A-Surface Reflectance image. Community structure measurement followed a stratified purposive sampling design along forest zonation. A spatial-based mangrove health index (MHI) model was applied to analyze forest healthiness distribution in each zone. Mangrove area was clearly classified into six genera-dominated zones such as Sonneratia, Rhizophora, Bruguiera, Ceriops, Xylocarpus and Lumnitzera from seaward to landward. The Rhizophora zone had the most extensive area proportion at approximately 68% of the total mangrove area. This study revealed that S. alba species dominated in the outmost zone at about 200% of IVI, while X. granatum and C. tagal were calculated in a larger IVI value in the more landward area. On the other hand, R. stylosa had a majority species composition in Rhizophora forest. According to spatial analysis of MHI, most zones had a majority area of excellent condition, emphasizing that the entire mangrove forest was pristine.

“…Kerapatan dan keragaman struktur vegetasi mangrove berperan penting sebagai perangkap endapan dan perlindungan terhadap erosi pantai (Zamroni, 2019). Sistem perakaran vegetasi mangrove mampu menahan erosi akibat gelombang air laut (Japa & Santoso, 2019). Selain itu, vegetasi mangrove juga membentuk habitat perlindungan bagi hewan-hewan muda dan juga sebagai substrat organisme epifit (Sani, et al, 2019).…”

“…Avicenia sp. merupakan jenis mangrove pionir yang berkembang baik pada area dekat laut dengan substrat lumpur berpasir yang kaya akan bahan organik dengan rentang toleransi salinitas yang luas (Japa & Santoso, 2019). Lumnitzera rasemosa dan Sonneratia alba merupakan jenisjenis dengan ukuran populasi yang sangat kecil (Tabel 1).…”

The area at the research site has a mangrove community that is experiencing disturbances due to the conversion of land into ponds. Therefore, the purpose of this study was to assess the actual condition of mangrove vegetation after land conversion. The method used in this research is a survey and the sampling point is determined randomly (random sampling). Furthermore, observations were made on two existing mangrove blocks, namely the Natural Block and the Rehabilitation Block. Observation plots were placed randomly in the Natural Bok and Rehabilitation Block. Randomization was carried out on the regional map by making a grid measuring 10x10m and numbered. The data were analyzed using the analysis of the diversity index value (Shannon-Wiener), the evenness index (Evenness), the proportion of vegetation at each growth level and the pattern of vegetation distribution (Morisita Index). The results showed that the value of species diversity in the Natural Block was 0.95 and the Rehabilitation Block was 0.99. This value is included in the category of low diversity. The evenness index obtained a value of 0.49 in the Natural Block and 0.45 in the Rehabilitation Block. This value indicates that the distribution of the number of individuals in each species is not evenly distributed. Vegetation is dominated by Trees (in the Natural Block) and Saplings (in the Rehabilitation block). The vegetation in the Natural Block is older than the Rehabilitation Block. Meanwhile, based on the value of the Morisita index, the distribution pattern of mangrove vegetation in the study area is included in the cluster category.
