Aida GR, Wardiatno Y, Fahrudin A, Kamal MM. 2016. Dynamic model of economic value of mangrove ecosystems Tangerang Coastal Area, Banten. Bonorowo Wetlands 6: 26-42. The purpose of this research is to estimate mangrove productivity through the production of litter; estimate the potential fisheries production through mangrove litter production approach; estimate the mangrove ecosystem value from potential fisheries from mangrove litter production, existing fisheries and aquaculture; determining a dynamic model of mangrove ecosystems value for fisheries and the aquaculture in coastal areas of Tangerang District, Banten. The study was conducted in May-July 2014, with the location of sampling conducted in the Kronjo Subdistrict, Tangerang District, Banten. The data required include mangrove vegetation characteristics, physical and chemical parameters of the aquatic environment, mangrove litter production, socio-economic data related to the utilization of mangrove ecosystem and secondary data related. The potential fisheries that supported from mangrove calculated by the method which developed by Mahmudi (2008), the value of fisheries existing and aquaculture obtained through consumer surplus approach. Based on the research, production of mangrove litter which consisting of Avicennia marina, Avicennia alba, Rhizophora mucronata and Sonneratia caseolaris reaches 3.47 g/m2/day or 12 492 kg/ha/yr. Coastal fisheries potential of the ecosystem can support 1134.01 kg/ha/yr with the value reached Rp 27 016 978.57/ ha/yr. The value of actual fisheries reached Rp 5442896260/ha/yr and aquaculture Rp 8 012 608/ha/yr. The result of dynamic model simulation shows that in the existing condition, the total value of mangrove use are not sustainable and continued to decline. While mangrove rehabilitation at least 2.27 ha/yr can maintain the sustainable the value of mangrove uses. Mangrove rehabilitation also needs to consider the composition of mangrove species to produce fishery potential that can be supported optimally and increase the total value of mangrove utilization.

Abstract. Kristiningrum R, Lahjie AM, Masjaya, Yusuf S, Ruslim Y, Ma’ruf A. 2020. Fauna diversity, production potential and total economic value of mangrove ecosystems in Mentawir Village, East Kalimantan, Indonesia. Biodiversitas 21: 1940-1953. Mangroves play important role in life. The benefits of the mangrove ecosystem consist of ecological and socio-economic values. However, it is a challenge to discern how the mangrove ecosystem provides a comprehensive economic value. This research is aimed to analyze the Total Economic Value (TEV) of mangrove ecosystems in Mentawir Village, North Penajam Paser District, East Kalimantan Province. This aim will be achieved by conducting fauna inventory, analysis of mangrove wood production potential, social-economic interviews, and infrastructure cost analysis as the inputs to calculate four elements (i.e. Direct Use Value, Indirect Use Value, Option Value, and Existence Value) to sum up the TEV. The research used a mixed-method combining both qualitative and quantitative methods. Fauna inventory was conducted using boat survey method and interviews with local fishermen. Data on mangrove wood production was obtained using the systematic random sampling method by establishing two plots with an area of one hectare for each plot to calculate mean annual increment (MAI) and current annual increment (CAI). The economic value of the mangrove ecosystem was calculated using market price values, replacement costs, and the Contingent Valuation Method (CVM). The results of fauna inventory consisted of 3 species of mammals, 1 species of reptile, 16 species of birds, 25 types of fish, 8 species of crustaceans, and 7 species of mollusks. The economic valuation resulted in the contribution of direct use value with 39.56% in the form of wood (94,875,000,000 IDR) and fishery products (103,500,000,000 IDR); indirect use value with 53.47% in the form of breakwater (38,028,881,407 IDR), abrasion resistance (218,549,528,110 IDR), and carbon sequestration (11,580,313,067); option value with 6.92% in the form of biodiversity (34,690,085,038 IDR); and existence value with 0.05% (241,500,000 IDR). All these resulted in the total economic value (TEV) of the mangrove ecosystem in Mentawir Village of 501,465,307,621 IDR. Therefore, this value can be the basis for policymakers in managing natural resources so that the ecosystem is more protected and sustainable, and can continue to provide environmental services for the welfare of the community.

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.

Muara Angke Wildlife Reserve (MAWR) is the smallest natural reserve area in Indonesia with a wetland ecosystem type, dominated by open swamp and mangroves, and greatly influenced by freshwater from the Angke River. Although small, this region plays an important role in protecting biodiversity, especially for mangrove ecosystems in Jakarta. However, this area has suffered severe degradation because of river pollution and decreasing salinity so that rehabilitation efforts carried out to maintain the presence of mangrove ecosystems. We asses the hydro oceanographic aspects, i.e. tidal conditions, sedimentation and bathymetry by conducting field survey and modeling. Based on the results, there is 0.35 m increase in the water level compare to previous period. The value of Formzhal 2.47 is obtained which indicates the mixed tide prevailing diurnal type, mainly because of the influence of the river, although sometimes their mixed tides with very different heights and periods. The tidal mounts in Muara Angke based on the Admiralty method are 0.94 meters. Then, from the results of the sediment test, it was found the type of mud sediment with a value of TSS between 23 mg/l - 74 mg/l. The result of this study is that the sustainability of the mangrove ecosystem in Muara Angke Wildlife Reserve depends on these three aspects. There needs to be mitigation efforts to reduce sedimentation and overcome freshwater immersion from rivers so that mangrove rehabilitation in this region can be successful.
