The species-specific potentiality of mangroves in terms of ecosystem services is not well understood. Therefore, this study addressed the carbon sequestration and litterfall production potentiality of six major species in Sundarbans, Bangladesh, by evaluating three consecutive years of inventory data, including the stand variables and weather events impacts on them. The total mean aboveground, belowground biomass, biomass accumulation, and carbon accumulation rate were 243.4 Mg ha⁻¹, 132.2 Mg ha⁻¹, and 14.3 Mg ha⁻¹ yr⁻¹, 7.2 Mg ha⁻¹ yr⁻¹, respectively. Carbon stocks and sequestration rates are significantly influenced by stand variables such as diameter, density, and species composition. Large-sized trees and stands with lower density sequester more carbon than small-sized trees, and higher density stands. Among species, Avicennia officinalis contributed higher carbon to carbon stocks and also significantly different from other species for sequestering carbon, whereas Aglaia cucullata was the lowest. Mean annual litterfall was 10.01 Mg ha⁻¹ yr⁻¹, with the maximum litterfall for Hereteira fomes (19.2 Mg ha⁻¹ yr⁻¹) during the late summer or wet season (e.g., April to August). Litterfall showed a significant positive (p < 0.001) relation to weather variables such as rainfall, temperature, wind, etc. This study reports that the rate of carbon sequestration in Sundarbans was 17.21 Mg C ha⁻¹ yr⁻¹, which corresponds to 62.6 Mg ha⁻¹ yr⁻¹ CO₂. High carbon stocks, carbon sequestration, and litterfall production rate in Sundarbans demonstrate the significance of mangrove species and Sundarbans in the global carbon budget. This information can be used in species selection for plantation, species conservation, and ecosystem management purposes at the regional and global levels.

红树林在生态系统服务方面的物种特异性潜力尚不清楚。因此，本研究通过评估连续三年的清单数据，包括林分变量和天气事件对它们的影响，解决了孟加拉国 Sundarbans 六种主要物种的碳固存和凋落物生产潜力。总平均地上、地下生物量、生物量积累和碳积累率分别为 243.4 Mg ha ^-1、132.2 Mg ha ^-1和 14.3 Mg ha ^-1 yr ^-1、7.2 Mg ha ^-1 yr ^-1， 分别。碳储量和封存率受林分变量（例如直径、密度和物种组成）的显着影响。密度较低的大型树木和林分比小型树木和较高密度的林分固碳更多。在物种中，Avicennia officinalis 对碳储量的贡献较高，并且在固碳方面也与其他物种显着不同，而 Aglaia cucullata 最低。年平均凋落物为 10.01 Mg ha ^-1 yr ^-1，Hereteira fomes 的最大凋落物（19.2 Mg ha ^-1 yr ^-1) 在夏末或雨季（例如 4 月至 8 月）。凋落物与降雨、温度、风等天气变量呈显着正相关 (p < 0.001)。本研究报告称，孙德尔本斯的碳封存率为 17.21 Mg C ha ^-1 yr ^-1，对应于 62.6 Mg ha ^-1 yr ^-1 CO ₂。孙德尔本斯的高碳储量、碳固存和凋落物生产率证明了红树林物种和孙德尔本斯在全球碳预算中的重要性。该信息可用于区域和全球层面的种植、物种保护和生态系统管理的物种选择。
