Full textAbstract:
Mangroves provide multiple ecological functions such as connectors and balancers of land and sea ecosystems. The presence of mangroves in coastal areas is very important for reducing the impact of tsunamis and tidal flooding. The role of local communities in the form of community-based tourism models, in conserving mangrove forests has not been extensively studied. This study aims to fill the gap in evaluating local communities’ involvement, particularly under the tourism-based communities’ model, in conserving mangroves and, at the same time, gaining economic benefits. This study was conducted in the mangrove villages of “Patikang,” Citeureup Village, and Pandeglang Regency. This study applied mixed methods that combine both quantitative and qualitative approaches. Primary data were obtained directly from the local community through using questionnaires, interviews, and field observations. Secondary data collection was carried out through a literature review of mangrove conservation and community development in coastal areas. Our study found that local community-based tourism namely “Putri Gundul” played a very important role in increasing community awareness to conserve mangrove forests. The community has gained more knowledge on the biology of mangrove species and the ecology of mangroves for mangrove restoration. Furthermore, the involvement of local communities in mangrove conservation and restoration can increase the economy of communities by producing various products from mangroves.

Abstrak: Mangrove atau hutan bakau sangat penting dalam hal ekologi dan keanekaragaman hayati dengan manfaat seperti perlindungan garis pantai, tempat pembibitan biota laut, serta menangkap dan menyimpan karbon. Hutan bakau dapat hilang akibat gangguan antropogenik dan variasi lingkungan. Upaya rehabilitasi hutan bakau dapat mengembalikan berbagai fungsinya terutama bagi wilayah pesisir. Di Desa One Waara, pemukiman warganya memanjang di sepanjang garis pantai dengan kondisi tanaman bakau yang kurang terawat bahkan terdapat lokasi yang hampir tidak ditemukan bakau di pesisir pantainya. Hal ini tentu sangat mengkawatirkan karena ketiaadaan fungsi hutan bakau bagi daerah tersebut. Tujuan kegiatan ini adalah untuk menggugah kesadaran masyarakat tentang pentingnya peranan mangrove sehingga dapat berpartisipasi dalam penanaman, pemeliharaan, dan pengelolaannya. Kegiatan ini melibatkan 34 mahasiswa dan dosen program studi pendidikan biologi, 15 mahasiswa KKA UM. Buton serta 43 orang warga Desa One Waara sebagai mitra. Pelaksanaannya meliputi: sosialisasi, penanaman, pemeliharaan mangrove, dan evaluasi secara lisan dan tulisan melalui wawancara dan kuesioner. Evalusi menunjukkan peningkatan pemahaman masyarakat dari 74% menjadi 87,4%. Wujud kesadaran dan kepedulian masyarakat terlihat dari partisipasinya dalam kegiatan ini.Abstract: Mangroves are important for ecology and biodiversity, with benefits such as shoreline protection, marine life nursery, and carbon capture and storage. Mangrove forests can be lost due to anthropogenic disturbances and environmental variations. Mangrove forest rehabilitation efforts can restore its various functions, especially in coastal areas. In One Waara Village, settlements extend along the coastline with less well-maintained mangroves, and there are even locations where there are almost no mangroves on the coastline. This is certainly very concerning because of the absence of mangrove forest functions in the area. The purpose of this activity is to raise public awareness about the important role of mangroves so that they can participate in planting, maintaining, and managing them. This activity involved 34 students and lecturers of the biology education study programme, 15 Community Service Program of UM. Buton, and 43 villagers of One Waara village community as partners. The implementation includes socialisation, planting, mangrove maintenance, and verbal dan written evaluation through interviews and questionnaires. The evaluation showed an increase in community understanding from 74% to 87.4%. Community awareness and concern can be seen from their participation in this activity.

The coastal ecosystems of mangroves and beach forests are key to Climate Change adaptation and mitigation (CCAM) through their services of coastal protection, carbon sequestration, and provision of seedlings of pioneering (beach forest) species for lowland reforestation. The paper discusses science-based CCAM interventions that combine my formal training in marine biology and the need for coastal protection in the local communities where my environmental NGO operates. These initiatives include mangrove ecoparks, ecologically sound mangrove rehabilitation, coastal greenbelts of mangroves and beach forests, reversion of abandoned fishponds to mangroves, and beach forest nursery. It gives recommendations to government agencies and non-government organizations alike to protect mangroves as ecoparks, establish protective coastal greenbelts, and revert abandoned fishponds to mangroves.

Full textAbstract:
This study aimed to elucidate the inputs and exports of carbon and nitrogen organics by mangrove of Tinanggea, Southeast Sulawesi. The contents of carbon and nitrogen organics in mangrove litters were determined from twice monthly of litterfall collection at the Biology Laboratory of FMIPA, UHO. The inputs and exports of carbon and nitrogen organics by mangroves were calculated based on the monthly litterfall production of mangroves in each stasiun. The input of carbon and nitrogen organics from mangrove litter ranges from 11,72 to 14,30 ton/ha/year for carbon, and ranges from 0,007 to 0,16 ton/ha/year for nitrogen, while they were higher at station T5 and the lower on the T2 station. The mangrove exports organic carbon ranging from 3,52 to 4,29 ton/ha/year, while its organic nitrogen export ranges from 0,07-0,16 ton/ha/year. This study results realized that the inputs and exports of carbon and nitrogen organics are very dynamic in the mangrove ecosystem that indicated their important role on maintaining the productivity of the coastal environment in the Tinanggea and its surrounding areas.

Full textAbstract:
Mangrove degradation is a well-documented trend, but the spread of mangroves within the Siangshan Wetland in Hsinchu, Taiwan, runs contrary to that trend. The spread of mangroves changes the structure and functions of habitats for benthic organisms, causes infilling of estuaries and flooding and creates breeding grounds for small black mosquitoes. A large-scale mangrove-removal project was undertaken by the Hsinchu City Government from October 2015 to March 2016. They also investigated the consequences of mangrove removal on benthic organisms and adjacent habitats from October 2015 to September 2016, and the density, species count, Shannon–Wiener index (H′), and Pielou’s evenness index (J′) of the mangrove and non-mangrove regions were compared. In this study, we used satellite telemetry images to monitor fluctuations in mangrove density from 2006 to 2016. The non-mangrove region exhibited more variations than the mangrove region. After mangrove removal, species returned to their original habitats and noteworthy biological values significantly increased in the mangrove regions. This study presents evidence to argue that mangrove removal benefits benthic organisms. The results indicate that mangrove removal can be an appropriate habitat rehabilitation strategy for benthic organisms. The ecological findings of this study can inform coastal managers or other officials who seek to steward mangrove biomass.

Mangrove rehabilitation has implications for important ecological, social and economic values for coastal communities. The mangroves ecosystem Karawang Regency is still under pressure due to the management and utilization that does not pay attention to the sustainability aspect. The rehabilitation plan to mangrove management must be adapted to the nature and characteristics of the habitat. This study aims to formulate technical considerations for the direction of a rehabilitation plan based on an ecological approach and the dynamics of the mangrove ecosystem. The methods used in this study were geospatial approach that integrated with field quanitative and qualitative data. The results show that the total of mangrove potential area in Karawang Regency was 19,139.53 ha, consisting of 421.95 ha (2.2%) of vegetated area and 18,717.58 ha (97.8%) of unvegetated area. We integrate mangrove typology, mangrove stand density, physical parameters, and land use as the basis for determining the direction of rehabilitation planning. In the estuarine deltaic mangrove typology, we aim at protecting with natural regeneration. In infringe areas, we recommend constructing natural coastal structures before planting. On the backward for intensive planting. Furthermore, mangroves with low density, medium density, and high density are recommended for planting, species enrichment, and protecting respectively, and on the pond with implementing the mixed mangrove-aquaculture system to bridge between rehabilitation effort and economic needs of coastal communities.

ABSTRACT Mangroves are dynamic and unique inter-tidal ecosystems, common in tropical and subtropical coastal environments. They are among the world’s most productive ecosystems and are important in protecting coasts from erosion by fierce tides, in promoting the diversity of marine organisms and fisheries by contributing a quantity of food and providing favourable habitats for animals. These economic uses of mangroves indicate that they play an important role in the lives and economies in the coastal regions of different countries. Mangrove forests are under immense threat worldwide due to their multiple economic uses and alterations of freshwater inflows by various upstream activities in catchment areas. Mangrove plants with unique adaptations play a crucial role in sustaining life in mangrove forests. Their reproductive biology is central to understanding the structural and functional components of mangrove forests. The success of sexual reproduction and subsequent population expansion in mangrove plants is linked to flowering timings, pollinators and tidal currents. Viviparous and cryptoviviparous plants are true mangroves while non-viviparous ones are mangrove associates. The dispersal propagule is seedling in viviparous and non-viviparous plants while it is seed in nonviviparous plants. In this study, viviparous and crypto-viviparous species were included for study. These species are self-compatible, self-pollinating and also cross-pollinating; such a breeding system is a requirement for the success of sexual reproduction and subsequent build up and expansion of population. They are entomophilous in the study region. The viviparous plants include Ceriops tagal, C. decandra, Rhizophora apiculata, R. mucronata, Bruguiera gymnorrhiza and B. cylindrica. The non-viviparous plants include Avicennia alba, A. marina, A. officinalis, Aegiceras corniculatum and Aegialitis rotundifolia. Sexual reproduction and regeneration events are annual in these plants and are dependent on local insects, tidal currents and nutrient content in estuarine environment. In recent times, erratic and insufficient rainfall together with industrial pollutants released into rivers is causing negative effects on the growth, development and regeneration of mangrove flora. In effect, there is a gradual decrease in mangrove cover. Added to this is continuous exploitation of mangrove plants for fuel wood, creation of shelters for cattle and changes for industrial establishments and aquaculture development in estuarine regions. As a consequence, the existing mangrove cover is struggling to survive and also not in a position to support local needs and provide livelihood opportunities through fishery resources. Further, reduced mangrove cover is showing catastrophic effects on fishing communities who live along the shore line during the period of cyclonic surges and tsunami events.

Full textAbstract:
Mangroves are among the most productive marine and coastal ecosystems and play an important role in maintaining the stability and diversity of fish communities. To explore the structure of mangrove fish communities in China, we compiled previous studies, monographs, and two databases on 54 mangrove areas published in the past 30 years. Mangrove fish communities in China comprised Osteichthys (597 species) and Chondrichthyes (14 species), representing 611 species in 344 genera, 117 families, and 28 orders. Perciformes were the predominant taxon, with 350 species in 52 families, accounting for 57% of the total species richness. Reef fish accounted for 29.62%. With regard to feeding groups, there were 328 carnivorous species (53.68%), 214 omnivorous species (35.02%), 41 herbivorous species (6.71%), and 28 detritivores species (4.58%). Classified by body size, 57.61% were small-sized, 24.22% medium-sized, and 18.17% were large-sized fishes. A total of 5.23% (32 species) of these mangrove fish are currently on IUCN red lists, i.e., 2 species are critically endangered, 4 are endangered, 12 are vulnerable, and 14 are near threatened. Cluster analyses shows that Chinese mangroves fish were divided into two categories, i.e., coastal mangrove and island mangrove type. This is closely related to the distribution of reef fish. Moreover, the number of fish species showed a strong positive correlation with mangrove area, but not with latitude. The main reasons may be the subtropical and tropical geographic locations, as well as the characteristics of the South China Sea and the Taiwan Warm Current. The size and integrity of mangrove area are crucial to the local ecosystems; thus, protecting and restoring mangroves is of great significance to large-scale ecosystem-stability and local biodiversity.

Mangrove is the key vegetation in the transitional zone between land and sea, and its health assessment can indicate the deep-level ecological information. The LAI and six key nutrients of mangrove were selected as quantitative evaluation indicators, and the decisive evaluation method of mangrove growth was expected. The mangrove reserve of Dongzhai Port National Nature Reserve in Hainan Province, China, was selected as the study area, with an area of 17.71 km2. The study area was divided into adjacent urban areas, aquaculture areas, and agricultural production areas, and key indicators are extracted from satellite hyperspectral data. The extraction process includes spectral data preprocessing, spectral transformation, spectral combination, spectral modeling, and precision inspection. The spatial distribution of LAI and six key nutrient components of mangrove in the study area were obtained. LAI and Chla need to calculate the index after high-order differentiation of the spectrum; MSTR and Chlb need to calculate the envelope after the second-order differential of the spectrum; TN and TP are directly changed by original or exponential spectrum; the spectral transformation method adopted by TK was homogenization after first-order differential. The results of the strength of nutrient content along the three regions show that there was no significant difference in the retrieval index of mangroves in the three regions, and the overall health level of mangroves was consistent. Chla was the key identification component of mangrove growth and health. The contents of nutrient elements with correlation coefficient exceeding 0.80 include MSTR and TK (0.98), Chla and TP (0.96), Chla and TK (0.87), MSTR and Chla (0.86), MSTR and TK (0.83), and MSTR and TP (0.81). The study quantifies the relationship between different LAI and nutrient content of mangrove leaves from the perspectives of water, leaf biology, and chemical elements, which improved our understanding of the relationship between key components during mangrove growth for the first time.

Mangroves including those that are distributed in the coast of North Sumatra containpolyisoprenoid with varying levels of polyprenol and dolichol constituents. Differences in polyisoprenoid levels were closely related tothe salinity of sea but the information about their biological activities is scarce. The present study aimed to describe the biologicalactivities, antimicrobial, antioxidant, and antifungal effects of polyisoprenoid extracts from sixteen mangrove species of North Sumatra,Indonesia. Polyisoprenoids were isolated from mangrove leaves and tested for their antimicrobial activity against Escherichia coli,Staphylococcus aureus, and Candida albicans. Meanwhile, their antioxidant activity was represented by their capacity in scavengingDPPH (2,2-diphenyl-1-picrylhydrazyl) free-radical agents. The most predominant polyisoprenoids found in sixteen mangrove leafextracts was dolichols (75%). Polyprenols-dominant species, Acacia auriculiformis, Hibiscus tiliaceus, Pongamia pinnata, and Ricinuscommunis, and dolichols-dominant species, Avicennia lanata, Av. marina, Av. officinalis, Barringtonia asiatica, Bruguieragymnorrhiza, Calophyllum inophyllum, Nypa fruticans, and Pandanus odoratissimus, inhibited the growth of E. coli and S. aureus.However, the antioxidant activity of those sixteen mangrove species was of a weak category. Surprisingly, all other mangrovespolyisoprenoid extracts did not inhibit C. albicans growth. This study suggested that polyisoprenoids in mangroves have potentialantibacterial properties to be developed further.

This research was carried out from March to April 2021 in the coastal area of Kuala Jambi District, Tanjung Jabung Timur Regency, Jambi Province. The samples were processed at the Marine Biology and Marine Chemistry Laboratory, Faculty of Fisheries and Marine, Universitas Riau, which aims to examine the density of mangroves, analyze the sedimentation rate, and know the relationship between mangrove density and sedimentation rate. A survey method was used in this study. The results showed that the dominant mangrove species in the coastal waters of Kuala Jambi was Sonneratia alba with an Important Index Value (INP) of 103.5%. Mangrove density in the coastal waters of Kuala Jambi was included in good criteria with moderate and very dense mangrove cover. The bottom sediment of the coastal waters of Kuala Jambi was dominated by the type of sandy mud with a percentage of 42.23 - 55.63%. The value of the sedimentation rate in the coastal waters of Kuala Jambi at station 1 ranged from 94.401 to 141.602 mm/year. At station 2, the sedimentation rate was between 98.692 and 168.778 mm/year, while at station 3 the sedimentation rate was from 100.122 to 145.893 mm/year. Mangrove density had a very close relationship with the sedimentation rate, where the higher the mangrove density, was followed by the higher the sedimentation rate.

Full textAbstract:
Mangroves are coastal wetlands with high biodiversity and productivity, with great interaction with coastal environments. In the face of worldwide mangrove loss, restoration projects attempt to recover ecosystem composition and functioning over time. Our objective was to examine and compare the food webs in mangrove areas with different restoration times and in a reference mangrove in Términos Lagoon, Mexico. We estimated the trophic structure, identified the carbon resources that maintain aquatic consumers through the analysis of stable isotopes, and compared the trophic niche of the restored mangroves with the reference mangrove. We analyzed environmental variables, trophic structure, and contributions of resources during three seasons: rainy, dry, and “nortes”. Environmental changes and food structure changed in response to regional seasons. Bayesian mixing models indicated that food webs varied seasonally as a response to the primary productivity developed at Términos Lagoon. As expected, the assimilation of C3 plants in the reference mangrove was highest, as a primary (“nortes” season) and secondary resource (dry and rainy seasons). The restored mangroves depended mainly on allochthonous resources (seagrass, epiphytes, and phytoplankton). The assimilation of these resources highlighted the importance of connectivity and the input of sources of carbon from nearby coastal environments. Trophic niche analysis showed that the area with longer restoration time was more similar to the reference mangrove, which is evidence of the importance and efficacy of the restoration process, as well as the restoration of the ecosystem function over time.

Mangrove forests are found on coastlines in tropical and subtropical areas. The mangrove tree looks strange because its roots are partially above water, making it look like it is standing. Mangrove forests are coastal forests and critical habitats that act as nurseries and protect coasts from erosion. Determining the current status of sustainable management of mangroves is very important as a basis for planning future policies. The purpose of this study was to review the current status of mangroves and analyze the sustainability value of the mangrove ecosystem sustainability in the Biringkassi mangrove area, Pangkep district, Indonesia. This study is descriptive with a quantitative approach to conducting an inventory of mangrove ecosystems, including biophysical, social, economic and institutional data. Analysis of the sustainability of mangrove management The sustainability of the mangrove ecosystem was analyzed using the Rapid Assessment Fisheries (RAPFISH) software with the Multidimensional Scaling Method (MDS) method. The four aspects assessed were ecological, economic, social and institutional. The results of the sustainability analysis from the four dimensions showed that the ecological and institutional aspects have a moderate state of sustainability, but the economic and social aspects have a less sustainable state. Multidimensional analysis showed less sustainable management. Leverage analysis of 24 multidimensional attributes revealed eight highly influential attributes that can lead to change in management if not implemented correctly. Meanwhile, the analysis results should be maintained for properties that achieve low leverage so that the management value does not decrease.

Mangroves have been converted and degraded for decades. Rates of loss have declined over the past decades, but achieving resilient coastlines requires both conservation and restoration. Here, we outline the challenges for the global restoration of mangroves and what actions could enhance restoration. Ambitious global targets for mangrove restoration, if successful, could deliver global benefits of carbon sequestration, fisheries production, biodiversity, and coastal protection. However, large-scale mangrove planting efforts have often failed, and smaller projects may not deliver landscape-scale benefits, even though they are more suited to community management. Solutions to achieving global targets include reducing risks of large projects and increasing the uptake and effectiveness of smaller projects. Sustainable mangrove restoration requires investment in capacity building in communities and institutions, and mechanisms to match restoration opportunities with prospective supporters and investors. Global reporting standards will support adaptive management and help fully understand and monitor the benefits of mangrove restoration.

Wiryanto, Sunarto, Rahayu SM. 2017. Biodiversity of mangrove aquatic fauna in Purworejo, Central Java, Indonesia. Biodiversitas 18: 1344-1352. Mangrove areas have important roles of ecologic, socio-economic, and socio-culture in ecosystem. Mangrove areas in Purworejo go into degradation as an impact of illegal logging, fishpond area expansion, settlements expansion and extension of agriculture area. All of the activities will influence the communities’ structure of mangroves vegetation and aquatic fauna. The purposes of research are to observe (i) biodiversity of mangroves aquatic fauna; (ii) correlation between mangrove vegetation and aquatic fauna; and (iii) the influence of abiotic factors towards biotic condition in research sites. This research was conducted in June-September 2016 at 3 stations and was determined with purposive sampling method. The research stations are Gedangan (Station 1), Jatikontal (Station 2) and Ngentak (Station 3). Vegetation of mangrove and aquatic fauna were observed with method of line transect and sampling removal. Association between variables (vegetation and aquatic fauna) is analyzed with Pearson Correlation Test. Influence of abiotic factors (physics and chemicals) on biotic (vegetation and aquatic fauna) is analyzed with t-test and regression test. According to the research, 34 species of aquatic fauna are from mangroves area of Purworejo. Highest value of aquatic fauna is found in Station 3 (ID 2.50). Pearson correlation test between vegetation and aquatic fauna obtains r value of 0,104. The t-test results a significant difference (sig 0.000) between abiotic factors and biotic condition and shows the impact of changes on both. Further test with regression method also indicates a weak impact on changes on abiotic factors towards biotic condition (r2 0.032).

Mangroves in wetland ecosystems are diverse and play significant role in the adjacent communities on which they are dependent for their livelihoods. It is also important for fishery resources and nutrient inputs in marine and brackish water ecosystems. However, little is known about the tropical wetland lagoon ecosystems, particularly mangrove diversity and assemblages. Therefore, this present study was initiated to observe the mangrove species diversity and assemblages together with the conservation status in an important tropical wetland ecosystem in Setiu, Terengganu, Malaysia. In a variety of landward and small fringe island areas, three zones of square plots were selected (zones 1, 2 and 3) to address the objectives of this study. As a result, a total of 20 true mangrove species belonging to 11 genera from nine families were documented, of which, Avicennia rumphiana was listed as vulnerable (VU) by the IUCN. Twelve species of mangrove associates from 11 genera and nine families were also found in the investigated zones at Setiu. One of the mangrove associates, Intsia bijuga, was designated as vulnerable (VU) by the IUCN. The Shannon diversity index (H') of mangroves was found to be 1.08 at Setiu Wetland. Rhizophora mucronata was found to be well-expanded (H' = 1.05) followed by A. rumphiana, A. officinalis, Heritiera littoralis, A. corniculatum. Excoecaria agallocha, Lumnitzera racemosa, and A. ebracteatus (H' = 0.0) as the lowest. The findings of the present study revealed that mangroves in the Setiu Wetland are diverse and healthy compared to other mangrove ecosystems in the region. To maintain the health and function of the mangrove ecosystem in Setiu Wetland, proper monitoring is required.

In the Combretaceae family, only two species of Lumnitzera and one species of Laguncularia belong to mangroves. Among them, Lumnitzera littorea (Jack) Voigt. is an endangered mangrove plant in China for the limited occurrence and seed abortion. In contrast, Lumnitzera racemosa Willd. is known as the most widespread mangrove plant in China. Laguncularia racemosa C. F. Gaertn., an exotic mangrove in China, has the fast growth and high adaptation ability. To better understand the phylogenetic positions of these mangroves in Combretaceae and in Myrtales and to provide information for studies on evolutionary adaptation for intertidal habitat, the complete chloroplast (cp) genomes of Lu. racemosa and La. racemosa were sequenced. Furthermore, we present here the results from the assembly and annotation of the two cp genomes, which were further subjected to the comparative analysis with Lu. littorea cp genomes we published before and other eleven closely related species within Myrtales. The chloroplast genomes of the three Combretaceae mangrove species: Lu. littorea, Lu. racemosa, and La. racemosa are 159,687 bp, 159,473 bp, and 158,311 bp in size. All three cp genomes host 130 genes including 85 protein-coding genes, 37 tRNAs, and 4 rRNAs. A comparative analysis of those three genomes revealed the high similarity of genes in coding-regions and conserved gene order in the IR and LSC/SSC regions. The differences between Lumnitzera and Laguncularia cp genomes are the locations of rps19 and rpl2 genes in the IR/SC boundary regions. Investigating the effects of selection events on shared protein-coding genes showed a relaxed selection had acted on the ycf2, ycf1, and matK genes of Combretaceae mangroves compared to the nonmangrove species Eucalyptus aromaphloia. The phylogenetic analysis based on the whole chloroplast genome sequence with one outgroup species strongly supported three Combretaceae mangroves together with other two Combretaceae species formed a cluster in Combretaceae. This study is the first report on the comparative analysis of three Combretaceae mangrove chloroplast genomes, which will provide the significant information for understanding photosynthesis and evolution in Combretaceae mangrove plants.

AbstractRandom amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP) markers were used to study the genomic relationship among 11 members of Indian Rhizophoraceae represented by nine true mangroves and two non-mangrove species. The AFLP and RAPD bands were scored and analyzed for genetic similarities and cluster analysis was done which separated the 11 species studied into two main groups, the true mangroves and the non-mangroves. The polymorphism observed for these markers showed a high degree of genetic diversity among the constituent taxa of the family. The phylogenetic relationship inferred from molecular marker systems supported the traditional taxonomic classification of the family Rhizophoraceae based on morphological characters at the levels of tribe, phylogeny and delimitation of genera and species, except the intra-generic classification of the genus Bruguiera and the placement of Rhizophora in the family Rhizophoraceae.

Full textAbstract:
Mangroves are intertidal ecosystems that are particularly vulnerable to climate change. At the low tidal limits of their range, they face swamping by rising sea levels; at the high tidal limits, they face increasing stress from desiccation and high salinity. Facilitation theory may help guide mangrove management and restoration in the face of these threats by suggesting how and when positive intra- and interspecific effects may occur: such effects are predicted in stressed environments such as the intertidal, but have yet to be shown among mangroves. Here, we report the results of a series of experiments at low and high tidal sites examining the effects of mangrove density and species mix on seedling survival and recruitment, and on the ability of mangroves to trap sediment and cause surface elevation change. Increasing density significantly increased the survival of seedlings of two different species at both high and low tidal sites, and enhanced sediment accretion and elevation at the low tidal site. Including Avicennia marina in species mixes enhanced total biomass at a degraded high tidal site. Increasing biomass led to changed microenvironments that allowed the recruitment and survival of different mangrove species, particularly Ceriops tagal .

Biodiversitas 20: 160-170. The world has lost a large extent of mangroves, while rates of recovery of these ecosystems from natural re-growth and restoration are slow. We developed a hydrological restoration technique to investigate the importance of hydrological modification in mangrove restoration success. Ecological Mangrove Restoration was adopted to restore abandoned shrimp ponds at Tiwoho, Bunaken National Park, North Sulawesi. Hydrological modification resulted in the creation of various mangrove sub-habitat conditions. These conditions remained unstable within the first three years and became relatively stable after seven years. Tidal inundation and soil surface salinity appeared to be the major factors controlling mangrove establishment and growth. All natural recruits and planted trees grew faster and produced more propagules/fruits within a short period of time after the normal physical conditions achieved. The restored site was covered by approximately 91.3 % of vegetation with the same canopy species composition as the natural stands. The practiced hydrological restoration method was simple, cost-effective and can help other practitioners in improving their mangrove restoration techniques.

In this paper, we detail four Colletotrichum species found in mangrove ecosystems. Two new species, Colletotrichum rhizophorae and C. thailandica, and a new host record for Colletotrichum fructicola were identified in Thailand. Colletotrichum tropicale was collected from Taiwan’s mangroves and is a new record for Rhizophora mucronata. These identifications were established through a combination of molecular analysis and morphological characteristics. This expanded dataset for Colletotrichum enhances our understanding of the genetic diversity within this genus and its associations with mangrove ecosystems. The findings outlined herein provide data on our exploration of mangrove pathogens in Asia.

Abstract Mangrove planting project is one of the most beneficial conservation efforts in coastal areas in terms of environmental impact and carbon sequestration rate. We hypothesized that it would serve as an effective learning strategy if the planting project were planned and organized by the student within a structured biology course. This study examines the impact of the mangrove planting project as a climate initiative program within a biology course towards students’ climate literacy. In this study, 57 students who participated in a mangrove planting project within the Conservation of Coastal Resources course were assigned a climate change questionnaire. The change in participants’ climate literacy was measured before and after the intervention. Climate literacy is measured in three aspects i.e., climate action readiness, climate concerns, and pro-climatic attitude. The result shows that mangrove planting projects increase all measured aspects significantly, with climate action readiness showing the highest improvement. These findings confirmed the benefits of collaborative project-based learning to improve the students’ climate literacy.

Full textAbstract:
Coral reefs are degrading due to many synergistic stressors. Recently there have been a number of global reports of corals occupying mangrove habitats that provide a supportive environment or refugium for corals, sheltering them by reducing stressors such as oxidative light stress and low pH. This study used satellite imagery and manual ground-truthing surveys to search for mangrove-coral habitats in the Florida Keys National Marine Sanctuary and then collected basic environmental parameters (temperature, salinity, dissolved oxygen, pHNBS, turbidity) at identified sites using a multi-parameter water quality sonde. Two kinds of mangrove-coral habitats were found in both the Upper and Lower Florida Keys: (1) prop-root corals, where coral colonies were growing directly on (and around) mangrove prop roots, and (2) channel corals, where coral colonies were growing in mangrove channels under the shade of the mangrove canopy, at deeper depths and not in as close proximity to the mangroves. Coral species found growing on and directly adjacent to prop roots included Porites porites (multiple morphs, including P. divaricata and P. furcata), Siderastrea radians, and Favia fragum. Channel coral habitats predominantly hosted S. radians and a few S. siderea, although single colonies of Solenastrea bournoni and Stephanocoenia intersepta were observed. Although clear, low-turbidity water was a consistent feature of these mangrove-coral habitats, the specific combination of environmental factors that determine which mangrove habitats are favorable for coral recruitment remains to be defined. Circumstantial evidence suggests additional coral communities existed on mangrove shorelines of oceanside and backcountry islands until destroyed, likely by Hurricane Irma. These mangrove-coral habitats may be climate refugia for corals and could be included in ecosystem management plans and considered for their applications in coral restoration.

Full textAbstract:
The mahogany family, Meliaceae, contains 58 genera with only one mangrove genus: Xylocarpus. Two of the three species of the genus Xylocarpus are true mangroves (X. granatum and X. moluccensis), and one is a non-mangrove (X. rumphii). In order to resolve the phylogenetic relationship between the mangrove and non-mangrove species, we sequenced chloroplast genomes of these Xylocarpus species along with two non-mangrove species of the Meliaceae family (Carapa guianensis and Swietenia macrophylla) and compared the genome features and variations across the five species. The five Meliaceae species shared 130 genes (85 protein-coding genes, 37 tRNA, and eight rRNA) with identical direction and order, with a few variations in genes and intergenic spacers. The repetitive sequences identified in the rpl22 gene region only occurred in Xylocarpus, while the repetitive sequences in accD were found in X. moluccensis and X. rumphii. The TrnH-GUG and rpl32 gene regions and four non-coding gene regions showed high variabilities between X. granatum and the two non-mangrove species (S. macrophylla and C. guianensis). In addition, among the Xylocarpus species, only two genes (accD and clpP) showed positive selection. Carapa guianensis and S. macrophylla owned unique RNA editing sites. The above genes played an important role in acclimation to different stress factors like heat, low temperature, high UV light, and high salinity. Phylogenetic analysis with 22 species in the order Sapindales supported previous studies, which revealed that the non-mangrove species X. rumphii is closer to X. moluccensis than X. granatum. Overall, our results provided important insights into the variation of genetic structure and adaptation mechanism at interspecific (three Xylocarpus species) and intergeneric (mangrove and non-mangrove genera) levels.

Diversity and characteristics of mangrove vegetation in Pulau Rimau Protection Forest, Banyuasin District, South Sumatra, Indonesia. Biodiversitas 20: 1215-1221. The purpose of the study was to analyze the flora diversity and characteristics of mangrove vegetation in Pulau Rimau Protection Forest, Banyuasin District, South Sumatra. Data collected were the number and girth diameter of mangrove tree species, and aquatic ecology parameters using transect method. The sample plots size were 2m×2 m; 5m×5 m; 10m×10 m; for seedling, sapling, and tree, respectively. The observation plots were arranged in a row of 120 m length on two sides of the forest edge, namely Calik Riverbank and Banyuasin Riverbank. Data were analyzed using importance value index (IVI), Simpson’s diversity index and Sørensen’s community similarity. The study revealed that there were differences in mangrove characteristics in two study sites. There were 57 plant species identified inside and outside sample plots, but only 15 species (26.32%) among them were categorized as true mangrove species. Inside the sample plots, there were 11 and 10 mangrove tree species recorded on the Calik Riverbank and Banyuasin Riverbank, respectively, but only 7 species among them were found in both sites. The mangroves on Calik Riverbank were dominated by Nypa (IVI 53.59%) and Bruguiera (51.12%), while those on Banyuasin Riverbank were dominated by Sonneratia (66.91%) and Avicennia (51.73%). The Simpson’s diversity index for Calik Riverbank and Banyuasin Riverbank was 0.82 and 0.78, respectively, whereas the Sørensen’s coefficient of community between the two sites was 0.67.

Full textAbstract:
Samples of submerged, decaying leaves of red, black, and white mangroves (Rhizophora mangle, Avicennia germinans, and Laguncularia racemosa) were incubated on plates of eight different combinations of fungal inhibitors, bacterial inhibitors, and sporangium inducers added to a standard agar medium for isolating oomycotes (Protoctista: Oomycota; alias Oomycetes). The broad spectrum of agar preparations revealed no new oomycotic species for red or white mangroves; Halophytophthora vesicula (the delicate form) and Halophytophthora spinosa were overwhelmingly the most frequent species (to 88–90%, depending on medium, mangrove, and site). Other described species of Halophytophthora were rare (e.g., Halophytophthora bahamensis occurred twice, versus a total of 263 occurrences for H. spinosa). For black mangrove, however, the predominant oomycote (frequency ranging up to 90%, depending on medium and site) was an undescribed species of Halophytophthora with a mechanism of zoospore release involving the expansion of a clear plug into a tubular vesicle. Halophytophthora vesicula and H. spinosa occurred at almost four times lower frequencies on black mangrove than the undescribed Halophytophthora species. Media without inhibitors allowed interference from bacteria and labyrinthulas, with consequent reduction of oomycote frequencies by as much as a factor of four. Chloramphenicol application as the sole inhibitor at 150 mg∙L−1 resulted in significant interference from eumycotic fungi (oomycote frequency reductions to × 10). The best medium for exposing maximum frequencies of all three of the principal halophytophthoras was one with amphotericin B (2 mg∙L−1) as the polyene-macrolide fungal inhibitor.Key words: oomycotes, oomycetes, Halophytophthora, mangrove, selective medium.

Abstract. Kaskoyo H, Hartati F, Bakri S, Febryano IG, Dewi BS, Nurcahyani N. 2023. Satellite based analysis of mangrove cover and density change in mangroves of Tulang Bawang District, Lampung Province, Indonesia. Biodiversitas 24: 3019-3028. Being a threatened ecosystem of the world, mangroves require regular monitoring to identify areas that need improvement in conservation measures. Considering this, the present study aimed to assess the mangrove cover and density change in mangrove forest of Tulang Bawang District, Lampung Province, Indonesia. Data was collected by remote sensing techniques using satellite imagery viz., Landsat 5 in 2000 and 2010 and Landsat 8 in 2020. It was then analyzed using remote sensing method, namely Object-Based Image Analysis techniques using the unguided classification method to obtain mangrove cover data; while mangrove density information was obtained using the Normalized Difference Vegetation Index algorithm. The results revealed the decrease in mangrove cover and density between 2000 and 2020. The mangrove cover decreased from 7529 ha in 2000 to 5551 ha in 2020. Furthermore, density of mangrove forest has also witnessed change from dense density class in 2000 to medium density class in 2020. From this result, it is evident that mangroves of East Rawajitu Sub-district are degrading and require focused efforts to prevent the degradation. Communities, entrepreneurs, and governments have different motives for utilizing mangrove forests that result in damage, so reasonable efforts are needed to manage mangrove forests sustainably.

Floristic richness and diversity of Bintuni mangrove, Bird's Head Peninsula, West Papua, Indonesia. Biodiversitas 24: 2887-2897. Mangrove ecosystems play an important role in the functions of coastal protection, fish and other living-organism habitats, carbon storage, and the livelihood of local people. Yet, mangrove forests generally face ecological threats like anthropogenic pressures. However, fewer studies were carried out in this area, so this research aimed to reveal the vegetation diversity and richness in Bintuni, not only the true mangroves but also the mangroves associates with three different conditions, namely sandy areas called protection forests, disturbed forests called production forests, and delta called nature reserve. The results showed that species vegetation in the Bintuni Mangrove could be differentiated as true mangroves (29.82%) and mangrove associates (70.18%) of the total species richness of mangrove vegetation where in terms of taxonomic composition, the three forests encompassed 25 families, 47 genera, and 57 species clustered into 9 lifeforms. Then, the vegetation diversity and richness were highest in the nature reserve, and 34 (59.65% of total species number) species of vegetation in common share in three forest types. Consequently, frequent checking of vegetation richness is important since the Bintuni mangrove does not seem to have a significant threat like massive conversion of mangrove.

Kutai National Park (KNP) in East Kalimantan, Indonesia is blessed with natural mangrove forests. However, there is only very little information relating to the species composition and mangrove diversity. Therefore, this study was conducted to assess the mangrove tree species diversity and richness in Kutai National Park, East Kalimantan, Indonesia. The study results showed that the mangrove trees density was 1,214 trees/ha in the line transect vegetation survey with 1.7 ha plot. The number of mangrove species in KNP was 17 from 6 families. The dominant species with large numbers of individuals were Rhizophora mucronata, Rhizophora apiculata, and Bruguiera sexangula. The diversity index was low in mangroves in Pandan Bay Estuary, and Kaba Bay compared to that in Lombok bay’s mangroves.

Survival and growth rates of mangroves planted in vertical and horizontal aquaponic systems in North Jakarta, Indonesia. Biodiversitas 23: 687-694. Mangrove rehabilitation is aimed to reverse mangrove deforestation and degradation. Various efforts have been conducted to rehabilitate the degraded mangroves, yet problems arise when planting mangroves in the high and permanently water-logged areas in coastline. The aquaponic system is a mangrove planting method introduced to reduce the impact of permanent and high water inundation. This research aims to analyze the survival rate of mangroves planted using vertical and horizontal aquaponic systems in Jakarta's north coast and investigate the correlation between physico-chemical environmental parameters and the survival and growth rates of the planted mangroves. The results showed that the survival rate of mangroves planted in the vertical aquaponic system reached 55.4-96.9%. On the other hand, the highest survival rate in the horizontal aquaponic system was obtained in mangrove planting at 80-100 cm from the bottom with survived plants between 70-90%. The height growth rate of mangroves planted in the aquaponic system was between 0.95-2.33 cm/month. The correlation analysis showed that soil salinity, soil pH and water salinity had a high correlation to support living trees of mangrove seedlings. Rhizophora apiculata, Rhizophora mucronata, and Rhizophora stylosa had highest survival and adaptation in this planting system.

Mangrove gastropod distribution based on dominant vegetation classes and their relationship with physicochemical characteristics on fringe mangroves of Lembongan Island, Bali, Indonesia. Biodiversitas 25: 156-166. Mangrove ecosystems are important in supporting diverse marine life, offering refuge, reproductive grounds, and sustenance to various species. However, mangroves possess distinct zoning patterns determined by dominant species due to environmental variations that significantly impact the biodiversity of biota, particularly gastropods. A study on the Indonesian island of Nusa Lembongan revealed distinct communities of coexisting gastropod species in each mangrove vegetation zone. We discovered 29 distinct species of mangrove gastropods, with the Sonneratia mangrove zone having the most and the Lumnitzera zone having the least. Certain species, including Amphidromus perversus, Cerithium adustum, and Echinolittorina sundaica, were detected in only one of the mangrove zones. In each mangrove zone, the composition of gastropod species changed depending on the substrate type, e.g., soil, mangrove trunks, or mangrove leaves. The Shannon-Wiener diversity index values range from low to high diversity, and the community structure index values in mangrove zones vary. The evenness index varied by region, with Avicennia, Bruguiera, and Sonneratia having the highest index value. The findings indicate that mangrove vegetation zones are essential for maintaining diverse gastropod populations, with distinct composition and abundance patterns influenced by the distance of each mangrove zone from the ocean. This data may influence conservation efforts to preserve mangrove habitats and the diverse array of organisms that depend on them.

AbstractMangrove restoration has become a popular strategy to ensure the critical functions and economic benefits of this ecosystem. This study conducts a meta-analysis of the peer-reviewed literature on the outcomes of mangrove restoration. On aggregate, restored mangroves provide higher ecosystem functions than unvegetated tidal flats but lower than natural mangrove stands (respectively RR’ = 0.43, 95%CIs = 0.23 to 0.63; RR’ = −0.21, 95%CIs = −0.34 to −0.08), while they perform on par with naturally-regenerated mangroves and degraded mangroves. However, restoration outcomes vary widely between functions and comparative bases, and are mediated by factors such as restoration age, species, and restoration method. Furthermore, mangrove restoration offers positive benefit-cost ratios ranging from 10.50 to 6.83 under variable discount rates (−2% to 8%), suggesting that mangrove restoration is a cost-effective form of ecosystem management. Overall, the results suggest that mangrove restoration has substantial potential to contribute to multiple policy objectives related to biodiversity conservation, climate change mitigation and sustainable development.

Biodiversitas 23: 3685-3697. Mangroves in lagoon habitats play an important role in ecosystem functions. Many studies on mangrove habitats are available in coastal habitats, however, the information on the lagoon ecosystems in tropical climates is scanty, especially regarding its vegetation and carbon storage. This study was carried out to assess the status of species diversity, composition, zonal structure and carbon storage of mangrove vegetation in Setiu lagoon, Malaysia. We used the transect line plots method in representative landward and small fringe island areas. The results showed that the floristic diversity of mangroves comprised 18 true mangroves and 11 associates, of which Avicennia rumphiana and Ceriops decandra were listed as threatened by IUCN. The stem density and basal area ranged from 1533 to 3800 individuals. ha-1 and 18.98-37.97 m2 ha-1, respectively. The mean tree diameter was 9.80 ± 2.85 cm, with a tree height of 10.35 ± 2.14 m. The mangrove species with the highest importance value index (IVI) was Rhizophora mucronata with 134.86, while the lowest was Acanthus ebracteatus with 13.23. The study revealed that small fringe islands in the lagoon were more diverse with biodiversity index values always higher than the landward zone. Total biomass from the dominant mangrove species was estimated at 522.9 t ha-1 with estimated carbon storage of 261.45 t ha-1 and sequestration potential of 959.54 t CO2 ha-1. Compared to the other mangrove ecosystems elsewhere, this study recommends that the Setiu lagoon is considered to be a healthy and newly generated mangrove forest. Therefore, proper monitoring is needed to ensure mangrove ecosystem health and functions.

Diversity of reef fish species in presence of mangrove habitat in Ternate, North Maluku, Indonesia. Biodiversitas 23: 5184-5193. Research on reef fish has been widely reported, where information about reef fish communities is an important factor for evaluating fisheries management and coral reef management. Mangroves as the nursery, foraging, and growing areas were also important to assure sustainable reef fish fisheries. This paper studies reef fish abundance and diversity in Ternate Waters in the presence of mangrove in coral reef habitats. To determines coral reef condition underwater photo transect was performed while an underwater visual census (UVC) was used to determine the abundance and diversity of reef fishes in Ternate waters between 2017 and 2018. A total of 14 stations were used, with eight stations near the mangroves and six stations that did not contain mangroves. Based on the observation, fish species richness in mangrove absence was higher than in the presence of mangroves, with 68 and 65 species in 2017 and 66 and 62 species in 2018. However, the abundance of reef fish was recorded high in the presence of mangroves than in the absence of mangroves, with 390 and 289 individual differences in 2017 and 2018. Mangroves' complexity affected part of reef fish communities in Ternate water, particularly Lutjanidae, Serranidae, and Scaridae, which might influence the abundance of reef fishes rather than the species richness. In addition, carnivore shows a negative effect in the presence of mangroves, in contrast with herbivores. It is related to mangrove functioning as a temporary shelter when high-pressure presence in their natural habitat (reef) and a place for foraging. Therefore, mangrove management must be a consideration in the coral reef or fisheries management program.

Biodiversitas 24: 250-257. Many studies have focused on the ecological and socio-economic benefits of the mangrove ecosystem, yet limited information is available regarding the potential uses of non-timber products from mangroves for creative culinary products. This study aims to assess the production and carrying capacity of raw materials derived from mangrove vegetation to make processed food products using a case study from mangrove ecosystem in Kampung Nipah Mangrove Tourism Area, Sei Nagalawan Village, Perbaungan Sub-district, Serdang Bedagai District, North Sumatra Province, Indonesia. In doing so, we analyzed the species composition and abundance of mangrove vegetation to result in the production potential of raw materials used for culinary purposes. Ten mangrove species were recorded in the studied area with Acanthus ilicifolius, Rhizophora apiculata and Avicennia marina were the most important species at the seedling, sapling and tree level, respectively. The Kampung Nipah Mangrove Tourism Area utilizes three mangrove species as raw materials for food, namely A. marina, Soneratia caseolaris, and A. ilicifolius which are used as raw materials for making mangrove dodol (a sweet toffee), fruit syrup, and crackers, respectively. Based on the abundance of species used for mangrove culinary products, the abundance of A. marina and A. ilicifolius are highly available, while S. caseolaris is scarce. These results imply that the abundance of A. marina and A. ilicifolius is sufficient for dodol and crackers production, yet the abundance of S. caseolaris is not sufficient as raw material for syrup processing. Therefore, it is necessary to enrich the population S. caseolaris to support the production of mangrove syrup.

Changes in density level and mangrove land cover on Teluk Pandan Coast, Lampung, Indonesia, after 10 years of community-based management. Biodiversitas 24: 3735-3742. The mangrove ecosystem in the Teluk Pandan coastal area, Pesawaran District, Lampung Province, Indonesia, is part of the mega-biodiversity of mangroves in Indonesia. Specifically, the mangrove in this region has changed due to tourism, aquaculture, settlement activities and coastal abrasion. This study aimed to assess the changes in density level and area change of the mangrove forests at five coastal villages in Teluk Pandan during the period of community management from 2010 to 2020. The effort and success of the rehabilitation were reported in this study can be useful as a consideration of sustainable management of mangrove ecosystem both in Lampung and in other areas in Indonesia. Mangrove area was estimated through field surveys and data processing of satellite imagery from Landsat 5 in 2010 and Landsat 8 in 2020. The mangrove density level and area change were calculated by layering images of mangrove distribution from different years. The classification of mangrove density was determined based on the NDVI value. Satellite imagery was compared with field data collected from 20 observation points at five villages to ensure the density level and interpretation accuracy. Image data analysis showed the changes in mangrove area from 109.80 ha in 2010, an increase of 16.39% to 127.80 ha in 2020. The area of mangrove forest in the rare category decreased by 49.35%, the moderate category increased by 39.13%, and the dense category increased by 109.71%. The study confirmed the successful effort to manage and preserve mangroves in Teluk Pandan Sub-district. Eventually, community-based mangrove management (CBMM) and cross-sectoral and multi-stakeholder management (co-management) has become the core strategy in the successful management of mangrove at five coastal villages in Teluk Pandan Sub-district.

Abstract. Hilyana S, Rahman FA. 2022. Variabilities of the carbon storage of mangroves in Gili Meno Lake, North Lombok District, Indonesia. Biodiversitas 23: 5862-5868. Mangrove is one of the coastal vegetation that can act as carbon mitigation (carbon sink and carbon storage). This study aims to determine the potential for carbon sinks and storage in the leaves and roots of each type of mangrove found in Gili Meno lake, North Lombok, Indonesia. The research includes the identification of species and sampling (leaves and roots) of mangroves in the research quadrant. The organic carbon content of mangrove leaves and roots was tested using the Wakley and Black method. The results showed that there were 5 (five) types of mangroves in Gili Meno lake, namely: Avicennia marina, Lumnitzera racemosa, Bruguiera cylindrica, Rhizophora apiculata, and Excoecaria agallocha. The highest leaf tissue carbon content value was R. apiculata at 45.85%C or equivalent to 3.19 g.C, while in roots, A. marina was 50.06%C, equivalent to 4.49 g.C. In addition, the potential carbon stock in the leaves of the entire mangrove ecosystem in an area of 3 ha is 762.81 tons.C±199.257 and at the roots is 659.76 tons.C±394.848, while the largest potential carbon stock in leaf organs is the type of mangrove R. apiculata, which is 318.91 tons.C.ha-1. and at the root is the type of mangrove A. marina, amounting to 448.54 tons.C.ha-1. The estimated carbon dioxide uptake by the Gili Meno mangrove leaves is in the range of 130.36 g.CO2-168.27 g.CO2 or with an average of 154.34 g.CO2±14.376, while the species with the highest carbon dioxide absorption capacity is R. apiculata (268.27 g.CO2) and the lowest in the species of L. racemosa (130.36 g.CO2).

AbstractMangrove forests store high amounts of carbon, protect communities from storms, and support fisheries. Mangroves exist in complex social-ecological systems, hence identifying socioeconomic conditions associated with decreasing losses and increasing gains remains challenging albeit important. The impact of national governance and conservation policies on mangrove conservation at the landscape-scale has not been assessed to date, nor have the interactions with local economic pressures and biophysical drivers. Here, we assess the relationship between socioeconomic and biophysical variables and mangrove change across coastal geomorphic units worldwide from 1996 to 2016. Globally, we find that drivers of loss can also be drivers of gain, and that drivers have changed over 20 years. The association with economic growth appears to have reversed, shifting from negatively impacting mangroves in the first decade to enabling mangrove expansion in the second decade. Importantly, we find that community forestry is promoting mangrove expansion, whereas conversion to agriculture and aquaculture, often occurring in protected areas, results in high loss. Sustainable development, community forestry, and co-management of protected areas are promising strategies to reverse mangrove losses, increasing the capacity of mangroves to support human-livelihoods and combat climate change.

Local indigenous strategy to rehabilitate and conserve mangrove ecosystem in the southeastern Gulf of Kupang, East Nusa Tenggara, Indonesia. Biodiversitas 21: 1250-1257. The existence of local communities around mangrove ecosystems plays essential role to support the effort of conservation programs in this area. This study is aimed to investigate a set of situation faced by local communities in the southeastern Gulf of Kupang (SGK), East Nusa Tenggara Province which led to the rehabilitation of once degraded mangrove forests in SGK and the strategies to conserve the recovered mangrove forests. A case study approach was developed using purposive sampling to collect information regarding the historical situation of mangrove forests in SGK. Further, remote sensing method using multi-temporal observation data was used to investigate the changes in mangrove cover from 1994 to 2019. This study revealed that a series of situations became the fundamental of the success in retaining the existence of mangrove ecosystems in SGK. First, the negative impacts of mangrove degradation affected the communities badly in relation to their livelihoods in fisheries and marine sector as well as other environmental services. Then, this situation led to the emergent of a local champion to initiate mangrove rehabilitation efforts which firstly did not get attention from most of the communities. After some initial successes, the efforts of the local champion was then followed by other members of communities, triggering a bigger scale of mangrove rehabilitation. Having the mangrove recovered, the communities set of highly strict local indigenous rules in which every indigenous people who conducting illegal logging in the mangroves would be expelled from the village, while a large fine was given for outside people who did the similar action. Currently, more than 90% of respondents have understood the benefits of mangroves and derived advantages from it, particularly in improving their prosperity and security. The results of the success of mangrove rehabilitation and conservation in SGK was confirmed by the increasing extent of mangrove vegetation using remote sensing data. The case study of rehabilitation and conservation in SGK provided valuable learning for communities in other areas.
