Abstract

The objectives of this study were to analyze mangrove community structure, estimate carbon storage and CO₂ sequestration potential, assess the economic value of CO₂ sequestration, and formulate management strategies for mangrove forests in the coastal area of Bangko Subdistrict, Rokan Hilir Regency. This research was conducted in October 2024 in the coastal area of Bangko Subdistrict, Rokan Hilir Regency, Riau Province. The method applied was a survey-based approach. Sampling stations were determined using purposive sampling. Mangrove community structure data were collected using 10 m × 10 m quadrat transect plots. A total of six observation stations were established, with three plots per transect. The potential carbon stock of the mangrove ecosystem was calculated based on carbon content from trunk biomass, roots, litter, and sediment. Biomass carbon estimation utilized species-specific allometric equations. The results recorded seven mangrove species: Avicennia alba, A. eucalyptifolia, A. lanata, Bruguiera parviflora, Rhizophora apiculata, R. mucronata, and Sonneratia alba. The highest relative density and the highest relative frequency were recorded for A.alba at Station I (75%) and Station II (42.86%). The highest relative dominance was recorded for Sonneratia alba at Station V (52.05%). The highest Importance Value Index (IVI) was observed for Avicennia alba at Station I (151.15%). The mangrove ecosystem in the coastal area of Bangko Subdistrict has an average carbon stock potential of 382.37 tons/ha, with an estimated CO₂ sequestration potential of 1,277.21 tons per hectare, totalling 15,893,618.87 tons. The estimated average economic value of carbon sequestration is IDR 1,081,274,726/ha, equivalent to IDR 13,455,438,919,367. Sustainable mangrove ecosystem management as a contribution to climate change mitigation can be implemented through the following strategies: ecosystem rehabilitation and protection, strengthening governance and law enforcement, community empowerment and alternative livelihood development, increased awareness and cross-sectoral coordination, and continuous monitoring and research

Abstract

Mangrove ecosystems play a crucial role in climate change mitigation by absorbing and storing carbon in biomass and sediments. This study aimed to estimate biomass carbon stocks, sediment carbon, CO₂ sequestration, and the economic value of mangrove carbon. The research was conducted in May 2025 in Bengkalis District, Bengkalis Regency. A survey method was employed, utilizing data on mangrove species composition, tree density, and diameter at breast height (DBH). The results identified six mangrove species: Rhizophora apiculata, R. mucronata, Avicennia alba, Sonneratia alba, Xylocarpus granatum, and Excoecaria agallocha. The mangrove ecosystem in Bengkalis District exhibited an average aboveground tree carbon stock of 87.75 t ha⁻¹, root carbon stock of 36.77 t ha⁻¹, sediment carbon stock of 54.03 t ha⁻¹, and CO₂ sequestration of 456.97 t ha⁻¹. The estimated economic value of carbon was IDR 388,342,353 ha⁻¹. These findings indicate that the mangrove ecosystem in Bengkalis District has substantial potential as a carbon sink and storage system, highlighting the importance of sustainable management strategies to support climate change mitigation efforts

Abstract

ngroves are coastal ecosystems that play a very important ecological and economic role. This study aims to analyze mangrove species, density, and importance index. The method used was a survey method with the determination of research stations using purposive sampling, where the research location was divided into 3 stations based on criteria, namely station 1 mangrove forest located in Damai Village with relatively good mangrove conditions, station 2 mangrove forest located in Rukun Village which is a mangrove ecotourism area, and Station 3, a mangrove forest located in Murni Village, which is adjacent to a residential area. The results of water quality parameter measurements in Pangkalan Jambi Village showed salinity values of 19-22, pH values of 5.4-6.5, and temperatures of 29-30 ℃. Based on the study, five mangrove species were found in the mangrove forest area of Pangkalan Jambi Village: Rhizophora apiculata, Xylocarpus granatum, Nypa fruticans, Avicennia marina, and Talipariti. tiliaceum. The density in the tree category at station I had the highest density, 1566.66 ind/ha, while the lowest was at station II, 300 ind/ha. In the seedling category, the highest density was found at station I with a density value of 4800 ind/ha, while the lowest density was found at station II with a density value of 3466.67 ind/ha. In the seedling category, the highest density was found at station I with a density value of 7500 ind/ha, while the lowest density was found at station II with a density value of 5000 ind/ha. Based on the average Importance Value Index calculation, the highest INP value was R. apiculata at 249.295%, and the lowest was S. alba at 178.588%.
