“…In mixed‐mature stands, the evaluated soil carbon stocks range between 208 ± 35 and 363 ± 76 Mg C/ha (>66 year; Table S1, Appendix S1; Figure b; Figure S7, Appendix S5). These values fall within the range of those reported in the literature, ranging from 100 to 280 Mg C/ha in South China (Wang et al., ), 275 to 314 Mg C/ha in Mozambique (Stringer et al., ), 307 to 637 Mg C/ha in Kenya (Gress et al., ), 505.9 Mg C/ha in Mexico (Adame et al., ) to 517.1 Mg C/ha in Madagascar (Jones, Ratsimba, Ravaoarinorotsihoarana, Cripps, & Bey, ) and 537 Mg C/ha in Honduras (Bhomia, Kauffman, & Mcfadden, ). Globally, the highest soil carbon stocks were measured in Southeast Asia, reaching 2063.6 Mg C/ha in the estuarine mangroves of Sulawesi (Donato et al., ).…”

The role of mangroves in the blue carbon stock is critical and requires special focus. Mangroves are carbon-rich forests that are not in steady-state equilibrium at the decadal time scale. Over the last decades, the structure and zonation of mangroves have been largely disturbed by coastal changes and land use conversions. The amount of time since the last disturbance is a key parameter determining forest structure, but it has so far been overlooked in mangrove carbon stock projections. In particular, the carbon sequestration rates among mangrove successional ages after (re)establishment are poorly quantified and not used in large-scale estimations of the blue carbon stock. Here, it is hypothesized that ecosystem age structure significantly modulates mangrove carbon stocks. We analysed a 66-year chronosequence of the aboveground and belowground biomass and soil carbon stock of mangroves in French Guiana, and we found that in the year after forest establishment on newly formed mud banks, the aboveground, belowground and soil carbon stocks averaged 23.56 ± 7.71, 13.04 ± 3.37 and 84.26 ± 64.14 (to a depth of 1 m) Mg C/ha, respectively. The mean annual increment (MAI) in the aboveground and belowground reservoirs was 23.56 × Age and 13.20 × Age Mg C ha year , respectively, and the MAI in the soil carbon reservoir was 3.00 ± 1.80 Mg C ha year . Our results show that the plant carbon sink capacity declines with ecosystem age, while the soil carbon sequestration rate remains constant over many years. We suggest that global projections of the above- and belowground reservoirs of the carbon stock need to account for mangrove age structures, which result from historical changes in coastal morphology. Our work anticipates joint international efforts to globally quantify the multidecadal mangrove carbon balance based on the combined use of age-based parametric equations and time series of mangrove age maps at regional scales.

“…Those campaigns are expensive but necessary to develop a baseline understanding of C density. If C density has relationships to remote sensing parameters such as mangrove height as in the Trettin et al (2016) and the Bhomia et al (2016) papers, C stocks can be scaled to larger landscapes. Although protocols for measuring C density have been produced (Kauffman and Danato 2012), rapid assessment techniques (Chimner et al 2014) should be considered that balance both an acceptable level of uncertainty with the effort and expense to acquire the data.…”

“…They recommended that similar approaches using a stratified random approach and remote sensing should be considered in future inventories of mangrove ecosystems. Bhomia et al (2016) quantified C stocks in mangrove ecosystems on the Bay Islands and both the Caribbean and Pacific coasts of Honduras. They describe the C stocks of mangrove forests regionally, and separated among three commonly used height classes.…”

“…2), such that the highest TOC was in the 0-20 cm layer, except in coastal saltwater lakes and deltas, where it was in the 20-40 cm soil layer. The study revealed that topsoil was the key point of soil sequestration [41]. The TOC contents of Hainan Island were similar to those of some medium-sized forests in the Asia-Pacific region [14] and higher than those of common forests in southern China [46].…”
