Abstract Rapid developments on the coastal regions have become a major thread to mangrove ecosystems. The conversion of mangrove forest into fish ponds, housing and industrial sites make the area of this unique tropical ecosystem decline significantly in the last decade. To prevent further destruction of mangrove ecosystems due to human activities, conservation programs are needed. Therefore, information on mangrove's area as well as their distribution is needed. The main objective of this research was to demonstrate the ability of remote sensing and geographic information technology to provide reliable and accurate data on mangrove forest in Surabaya and thSidoarjo regions. A Landsat TM-5 imagery (acquisition date June 4 , 2009) data was utilized to produce the map. The results showed that in the 2009 period the area of mangrove forest in Surabaya and Sidoarjo was 378.19 Ha and 1236.42 Ha respectively. However, over 73.5% area of mangrove in Surabaya and 43.25% in Surabaya were under critical conditions. Anthropogenic factors and human influence were some of the main factors that cause the condition. Activities such as illegal and uncontrolled logging, conversion of mangrove's area and the lack of people's awareness in the importance of mangrove ecosystems were also problems that lead to the massive damage of mangrove forests.

Mangrove ecosystems have an important role in coastal areas. Mangroves have a function as a shelter, foraging for food, and breeding various aquatic biota. Damage to mangrove forests can cause the service of mangrove ecosystems to decrease, especially for mollusk life. Mollusks are one of the associated biotas of mangroves whose life is influenced by mangrove forests. Therefore, the purpose of this study was to determine the diversity of mollusks and the relationship between mollusk density and mangrove density in the mangrove ecosystem of the southern coast of East Lombok. A sampling of mollusks used the quadrate sampling method by purposive sampling by taking into account the mangrove species contained in the observation plot. The collected data were analyzed by diversity index, distribution pattern, association, and Pearson correlation coefficient. Then a simple linear regression analysis was performed with the independent variable (x) mangrove density and the dependent variable (y) mollusk density. The results of this study were the discovery of 22 species of mollusks consisting of 17 species of gastropods and five species of bivalves. The density of mollusks in the mangrove ecosystem of the southern coast of East Lombok is 44.50±2.63 ind./m2. The diversity index at the study site was classified as moderate, with a value ranging from 1.99 to 2.46. The distribution pattern of mollusks at the research site is clustered with an Id value > 1. There are eight mollusk species associated with three mangrove species from 22 mollusk species found. The linear regression equation y = 0.084x – 0.2963 with a Pearson correlation coefficient (r) 0.95 describes a strong relationship between the independent variable (x) mangrove density and the dependent variable (y) mollusk density. This study concludes that there is a significant relationship between mangrove density and mollusk density as indicated by F-hit(41.01) > F-table (7.70) and P-value (0.003) < (0.05).

Mangrove forests are ecosystems that make up coastal areas and river estuaries. The examples of mangrove ecosystems found in Indonesia are in Segara Anakan, Central Java. One of the aquatic biota with the economic value found in the mangrove forest ecosystem is the mud crab (Scylla spp.). The purpose of this study was to assess the distribution of mangrove crabs (Scylla spp.) to the presence of mangrove species in the mouth of the Donan River, Segara Anakan. A sampling of crabs and observations of mangrove vegetation were carried out at five stations spread from the river to the sea. The results showed that there were three types of mangrove crabs caught in the vicinity of the study, namely Scylla tranquebarica, S. olivacea, and S. serrata. The types of mangroves found include Rhizophora apiculata, R. mucronata, Avicennia rumphiana, A. alba, A. officinalis, and Nypa. Regression analysis showed that mangrove density correlated with the abundance of Scylla tranquebarica and Scylla olivacea, but contradicts the abundance of Scylla serrate. PCA analysis showed that the Crab species Scylla tranquebarica and Scylla olivacea were associated with mangroves of Avicennia alba, Avicennia rumphiana, and Rhizophora apiculata. Meanwhile, Scylla serrata crabs are associated with Avicennia officinalis.

Abstract. Raganas AFM, Hadsall AS, Pampolina NM, Hotes S, Magcale-Macandog DB. 2020. Regeneration capacity and threats to mangrove areas on the southern coast of Oriental Mindoro, Philippines: Implications to mangrove ecosystem rehabilitation. Biodiversitas 21: 3625-3636. Regeneration capacity is important as it determines the fate of an ecosystem. This study assessed six mangrove areas in the southern coast of Oriental Mindoro, Philippines to evaluate their regeneration capacity status. Four mangrove ecotypes were delineated namely seaward, middle, landward and riverine zones at each mangrove ecosystem, where dominant mangrove species were identified and selected for regeneration capacity study. Three subplots measuring 1 x 1 m2 were laid within the five 10 x 10 m2 survey plots established per zone. The juveniles were counted and categorized according to their height classes, using linear regeneration sampling method; where: RCI (≤40 cm) considered seedlings; RCII (41-150 cm) as saplings; and RCIII (151-≤300 cm) as small trees. Potential threats both anthropogenic and natural were determined through key informant interviews. Seven dominant species were identified across ecotypes in all mangrove sites, namely Avicennia marina, Avicennia rumphiana, Ceriops decandra, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, and Xylocarpus granatum. RCI (seedlings) is the most abundant across mangrove sites irrespective of the dominant species. Fishpond operation within the mangrove stand is considered a major threat to the juveniles and most mangrove ecosystems. Therefore, protection and constant monitoring of these mangrove ecosystems are necessary to ensure regeneration success in the future.

Hydrological Conditions

&lt;p&gt;Mangrove forests are mainly found in the intertidal zone. Their ability to live in saline water enables them to outcompete non-mangrove vegetation in harsh and specific coastal environment. Nevertheless, they can still be invaded by alien mangrove species in suitable hydrological conditions, possibly resulting in more fragile ecosystems. Subtropical mangrove ecosystem demonstrates high variability in mangrove growth and hydrological conditions. However, their interactions are not well-understood, especially for the mangrove interspecific competition in varying groundwater conditions. To address this issue, the present study developed a coupled three-dimensional groundwater-vegetation model based on MANTRA (MANHAM-SUTRA) to simultaneously simulate groundwater hydrodynamics and mangrove distribution. The developed model was then applied to a subtropical mangrove swamp invaded by Sonneratia spp. in Mai Po Nature Reserve, Hong Kong, China. Vegetation domain is updated yearly using the annual mangrove areas extracted from remote-sensing images from 2000 to 2018. Then, multidecadal simulations were performed to validate the model in simulating the interaction between groundwater and mangrove growth. For the piezometric head, all RMS errors are smaller than 0.2 m and the correlation coefficients are larger than 0.86, which proves the effectiveness of the model in groundwater level simulation within Mai Po. The seasonal variations in the groundwater salinity were also well captured in both the fringe forest and the mudflat. The simulated biomass of Sonneratia spp. is mainly distributed at the river outlets, which is also in good agreement with the historical measurements. The validated model can then be used to predict the invasion and the distribution of the exotic mangrove species in the context of future environmental changes for better management of mangrove swamps. Since Sonneratia is a common alien species in southern China, the model can also be used for regional management of mangrove invasion and conservation of native species. The insights obtained from this study may also provide references for other similar studies examining the interaction between coastal groundwater and vegetation.&lt;/p&gt;

<strong>Decomposition Rate of Leaf Litter in The Mangrove Ecosystem of Kelong Island, Bintan Regency.</strong> The mangrove forests in the southeastern part of Kelong Island have abundant carbon reserves that indicate high primary productivity areas. Decomposition of leaf litter, as a part of regional productivity, produces simple essential nutrients utilized to sustain the growth of mangroves. The purpose of this study was to determine the decomposition rate of leaf litter in each zone of the study, the Landward (L), Middlezone (M), and Seaward (S) which is distinguished by the abundance of plant species and in situ environmental parameters. The experiment was conducted in March–May 2015 in the mangrove areas of Island Kelong, Bintan regency. The decomposition process was observed at six time intervals, i.e. 2, 4, 7, 14, 28, and 42 days using net bag containing 10 g of wet leaves placed on the substrate surface. The results showed that L was a zone with highest percentage of decomposition (56.34 ± 20.58%) compared to the M and S, respectively for 51.59 ± 15.46% and 51.09 ± 8.70%. The highest rate of litter decomposition in zone L was 1.40 ± 0.82 g·m-2·day-1 that was significantly different from the zones M and S, respectively of 0.83 ± 0.89 g·m-2·day-1 and 0.78 ± 0.70 g·m-2·day-1.  Analysis of the coefficient of decomposition rate (k) indicated that the rate of decomposition in this region was high (k &gt; 0.01). The decomposition rate has a significant correlation with the abundance of mangrove species, the salinity value of the water, and soil temperature.
