Papyrus swamps have the potential to sequester large amounts of the carbon (1.6 kg C m-2 y-1) when detritus accumulates under water in anaerobic conditions, but they are a net source of carbon release to the atmosphere (1.0 kg C m-2 y-1) when water levels fall to expose detritus and rhizomes to aerobic conditions (Jones et al.)
