Excerpt
Wetlands have the ability to sequester atmospheric carbon into peat or soil organic matter. They represent the largest component of the terrestrial biological carbon pool and may exert a large influence on global carbon cycles because they store about one-third of the global terrestrial soil organic carbon (1,395 Gt [3.07 × 1015 lb]). Although much attention has been given to the role of freshwater wetlands as carbon sinks, particularly northern peatlands, changes in carbon storage in the many small, scattered salt marshes, especially inland saline-alkaline wetlands are poorly known. Carbon cycles in wetland ecosystems are regulated by a series of interacting processes between soil, hydrology, and vegetation, of which hydrology is probably the single most important determinant of ecological processes because its shifts or fluctuations can lead to soil organic matter decomposition or accumulation in wetlands.
