Ocean carbon sequestration through mangroves

Data

Mangroves sequester CO2 at a rate of 2-4 metric tons of CO2 per hectare per year. The total carbon stock (carbon already sequestered) in mangrove forests can range from 200 to over 1,000 metric tons of carbon per hectare (t C/ha) when considering both above-ground and below-ground biomass. While the above-ground biomass is easier to measure, the majority of the carbon in mangrove ecosystems is often stored in the anoxic (oxygen-free) soils beneath them, which can preserve carbon-rich organic materials for millennia.
