Abstract Mangrove forest in Kao Village, North Halmahera Regency, North Maluku Province, is a Key Biodiversity Area. Since 2017, the community has been protecting mangrove forests through Kao Village Regulation No.03/2007. In 2020, through the collaboration between stakeholders from universities, NGOs and the government, the Kao mangrove forest area of 300.92 Ha was designated as an Essential Ecosystem Area (EEA) based on the North Halmahera Regent Decree No.078/102/HU/2020. This study describes the biodiversity and the community-based conservation through stakeholder collaboration in the EEA of Kao. The study found that there are 13 mangrove species and 56 bird species, of which 10 are protected species. In 2020, the community has built a mangrove nursery and rehabilitated 8 ha of degraded mangrove forest with the participation of about 70 people. Since the establishment of EEA, the community has stopped hunting for eggs of the endemic moluccan scrubfowl (Eulipoa wallacei) and is trying to increase its population through semi-natural hatching on the beach. The community has also learned to use non-timber mangrove forest products and ecotourism through the support of stakeholders.

Mangrove forest ecosystems are habitat of various types of microorganisms, but now, problems of mangrove forests experience are in quality and wealth. Efforts to rehabilitate activities mangrove forests againts had been carried out but the results shown had not been maximized, so it is need the correct strategies to achieve the success for rehabilitation activities. The studied was conducted in Teluk Kupang, East Nusa Tenggara, covered coastal areas of Kupang's mangrove forests and coastal mangrove forests in Kupang district. The method used in this studied was a systematic sampling method that was systematically distributed across all the mangrove forest areas. The method used for salinity measurement was method of transmission and Transect Line Plots. Measurements was made in straight line and the size of the plot is 10 m x 10 m, the distanced between lines was 50 meters so that total lane is 547 with the number of plots of observation 1641 plots. The value of measurement results was made into the spread of salinity used the interpolation method. The condition of the crossed of mangrove forest located on coastal panoramas of Kupang city shows a salinity value of 10,26 - 26.33%, while salinity conditions was on the coast of Kupang ten district 10-42.33 ‰. The salinity condition was formulation of the environmental conditions mangrove forest on coast of the island as well as attempts to support management of mangrove forest activities. The distribution of different mangrove forest conditions along the coastal zone of North Sumatra shows an environmental condition that supports mangrove growth even though in some places the salinity values are high.

Implementation of the UN Sustainable Development Goals requires countries to determine targets for the protection, conservation, or restoration of coastal ecosystems such as mangrove forests by 2030. Satellite remote sensing provides historical and current data on the distribution and dynamics of mangrove forests, essential baseline data that are needed to design suitable policy interventions. In this study, Landsat time series were used to map trends and dynamics of mangrove change over a time span of 30 years (1987–2017) in protected areas of Hainan Island (China). A support vector machine algorithm was combined with visual interpretation of imagery and result showed alternating periods of expansion and loss of mangrove forest at seven selected sites on Hainan Island. Over this period, there was a net decrease in mangrove area of 9.3%, with anthropic activities such as land conversion for aquaculture, wastewater disposal and discharge, and tourism development appearing to be the likely drivers of this decline in cover. Long-term studies examining trends in land use cover change coupled with assessments of drivers of loss or gain enable the development of evidence based on policy and legislation. This forms the basis of financing of natural reserves of management and institutional capacity building, and facilitates public awareness and participation, including co-management.

Abstract. Ginantra IK, Muksin IK, Suaskara IBM, Joni M. 2020. Diversity and distribution of mollusks at three zones of mangrove in Pejarakan, Bali, Indonesia. Biodiversitas 21: 4636-4643. The diversity of mangrove species in mangrove zonations on the coast of Pejarakan plays an important role in the existence of faunal diversity, including those from mollusks. Mollusks are the dominant phylum associated with mangrove habitats, in addition to the species of the Crustacean subphylum. This research aimed to determine the diversity of mollusks and their distribution patterns in three mangrove zones in Pejarakan, Buleleng District, Bali Province, Indonesia. Data collection was conducted by establishing sampling plots across three mangrove zones, i.e. seaward zone, middle zone, and landward zone. There were 23 sampling plots in total with size of each plot was 1x1m. The species and number of individuals of each species of mollusks were recorded in each quadrat plot. The diversity of mollusks was calculated using the Shannon-Wiener index, evenness index, and dominance index, while the pattern of distribution of mollusks was measured using the Morisita index. The results of the study found 27 species of mollusks, consisting of 19 species from Gastropods group, 7 species from Bivalvia group and 1 species from Polyplacophora (chiton). The seaward zone showed the highest species diversity, while the landward zone had the lowest. Terebralia palustris had the highest abundance with 217 individuals/m2 and was distributed in the three mangrove zones. Planaxis sulcatus showed the highest abundance (87 ind./m2) in the seaward zone, and Telescopium telescopium showed a fairly high abundance and were distributed in the mid zone and the landward zone. In general, mollusks in the mangrove area of Pejarakan was distributed in a group/clustered pattern. The data from this research can serve as a reference in mangrove forest conservation efforts and mangrove forest used for ecotourism.
