Abstract Mangrove forests are a unique coastal ecosystem with trees adapted to a constantly fluctuating and sometimes extreme physical environment. Mangrove forests provide important ecosystem services that benefit local people and all of us in terms of climate regulation through the storage of greenhouse gasses in biomass. This research reports carbon stock, wood volume, tree density, and biodiversity indices for two mangrove forest areas in Langsa City Regency, Aceh Province, Indonesia. The two sites represent and inland area and an ocean-exposed area within a large mangrove forest ecosystem complex. The results of the analysis show that these two tracts are quite similar in terms of carbon stock and biodiversity even though they occupy different locations within the larger tract of mangrove habitat. The study confirms these are healthy forest areas with relatively high carbon stocks.

Forests reduce and store CO2 through a process of "sequestration" that is the storage of carbon from the atmosphere and its storage in several copartments such as plants, litter, and soil organic matter. Mangrove forest is a unique and unique type of forest because it is able to adapt to environments with high salinity, soil conditions without oxygen and once in a while. ne example of mangrove forests in Indonesia is mangrove forest in the Kumbe river estuary, Merauke Regency, Papua Province. The Kumbe river estuary is one of the eastern Indonesian waters bordering the Indian Ocean. At the Kumbe river estuary there has been no research on carbon stocks in the mangrove community. So it is necessary to do research on carbon stocks in the region. In this study the measurement of carbon stocks used was done by measuring carbon above ground, and ground. Above ground carbon stock components include trees, understorey, and litter. The mechanism for measuring above ground carbon stock is done by estimating biomass, which is then converted to carbon concentration. The results of this study indicate that the carbon stocks in trees, Understorey and litter in sequence are 85.55 Mg / Ha, 392.93 Mg / Ha and 70.75 Mg / Ha; 0.78 Mg / Ha, 1.26 Mg / Ha and 1.24 Mg / Ha and 2.04 Mg / Ha, 1.28 Mg / Ha and 1.2 Mg / Ha. As for the proportion of carbon stock values ​​found in mangrove forests that trees contribute greatly to total carbon stock. Keyword : Mangrove, carbon stocks, Merauke, Kumbe

Increasing CO2 concentration in the atmosphere is one of the factor which cause global warming. CO2 sequestration through mangrove forests is believed to be one of the efforts to reduce CO2 in atmosphere. This research was conducted in July 2019, aimed at estimating mangrove biomass, mangrove carbon stocks, soil organic carbon, and CO2 sequestration in mangrove forests in the coastal areas of Sungai Sembilan District, Dumai City, Riau Province. This research was conducted using the line transect plot method. Sampling is done by non destructive sampling by measuring DBH (Diameter at Breast Height) of mangrove trees, and soil sampling is done in a composite manner in each plot.. Mangrove biomass calculations done using allometric equations. Then, biomass is converted to carbon stock and CO2 sequestration, where the percentage value of carbon was 0.47 of biomass. As for the organic soil carbon calculation is done by multiplying the bulk density values, the percentage value of 0.47 and a depth of soil carbon.The results showed that the average estimated amount of mangrove biomass, mangrove carbon stocks, soil carbon stocks and CO2 sequestration were 621.46 tons/ha, 289.22 tons/ha, 1819.31 tons/ha and 1074.99 tons/ha. ANOVA analysis results showed that the amount of mangrove biomass, mangrove carbon stock, soil carbon stock and CO2 sequestration between stations were not significantly different (p> 0.05).

Abstract Background Although great efforts have been made to quantify mangrove carbon stocks, accurate estimations of below-ground carbon stocks remain unreliable. In this study, we examined the distribution patterns of mangrove carbon stocks in China and other countries using our own field survey data and datasets from published literature. Based on these data, we investigated the possible relationships between above-ground carbon stock (AGC) and below-ground carbon stock (BGC) for mangrove forests, aiming to provide a scientific basis for estimation of total mangrove carbon stocks. Results The average above-ground carbon stock in each region was sizeable (ranging from 12.0 to 150.2 Mg/ha), but average below-ground carbon stock was dominant (ranging from 46.6 to 388.6 Mg/ha), accounting for 69–91% of total carbon stock at the sites studied in China. Significant positive relationships were found between above-ground and below-ground mangrove carbon stocks, with the best fitting equation as BGC = 1.58 * AGC + 81.06 (Mg/ha, R2 = 0.62, p < 0.01, n = 122) for China. Such linear relationships vary for mangrove forests of different types and locations, from different geographical regions in China to other countries worldwide. Conclusion The positive relationship we found between above- and below-ground carbon stocks of mangrove forests in China and worldwide can facilitate more accurate assessments of mangrove blue carbon stocks at regional or global scales using modern techniques including remote sensing.
