Impact of Shrimp Ponds on Mangrove Blue Carbon Stocks in Ecuador

Mangrove forests play an important role in mitigating climate change but are threatened by aquaculture expansion. The inclusion of mangroves in climate change mitigation strategies requires measuring of carbon stocks and the emissions caused by land use change over time. This study provides a synthe...

Two mangrove strata were identified according to their height and basal area: medium-statured mangrove (lower height and basal area) and tall mangrove (greater height and basal area).

For both strata, trees had a maximum height (>30 m), and their density was greater than 827 ha􀀀1. Total ecosystem level carbon stocks (measured to 1 m soil depth) were 320.9 Mg C ha􀀀1 in medium-statured mangroves and 419.4 Mg C ha􀀀1 in tall mangroves. The differences are attributable to higher basal area, soil organic carbon concentrations and salinity, tidal range, origin of allochthonous material, and herbivory patterns. Mangrove soils represented >80% of the total ecosystem carbon. Ecosystem carbon stocks were lower (81.9 Mg C ha􀀀1) in the shrimp farms, 50% less than in undisturbed mangroves. Our results highlight mangroves as tropical ecosystems with extremely high carbon storage; therefore, they play an important role in mitigating climate change. 2021-07-05T05:30:41Z 2021-07-05T05:30:41Z 2021-06 Artículo https://doi.org/10.3390/f12070816 https://repositorio.catie.ac.cr/handle/11554/11029 en Forests, Volumen 12, numero 7, (2021) info:eu-repo/semantics/restrictedAccess application/pdf
