- OC concentrations at two mangrove adjacent sites were significantly higher than those at non-mangrove adjacent sites
- “At each set of the three seagrass sample stations located at varying distances from mangrove or land edge the OC concentrations of the two most offshore were not significantly different from each other, but were significantly lower than stations closest to the mangrove or land edge.” (2)
- Seagrass meadows in North Sulawesi are rich in organic carbon storage.
- “The soil OC concentrations in our study are higher than those reported elsewhere in Southeast Asia further confirming that seagrass meadows in North Sulawesi are rich in soil OC and are sites of substantial carbon storage.” (5)
- The role seagrass plays in carbon storage is geographically variable.
- “...in our study seagrass tissue contributed a minimal proportion of the soil OC in the meadows adjacent to mangrove forests. Even in the two non-mangrove adjacent meadows, seagrass was rarely the dominant OC source in the underlying seagrass soils.” (6)
- Large organic carbon concentrations are more likely to be associated with mangroves than seagrass beds. Larger organic carbon concentrations in seagrass are directly linked to interactions between seagrass and mangroves.
- “...in our study seagrass tissue contributed a minimal proportion of the soil OC in the meadows adjacent to mangrove forests. Even in the two non-mangrove adjacent meadows, seagrass was rarely the dominant OC source in the underlying seagrass soils.” (6)
- “The exported OC in the form of mangrove detritus could be efficiently trapped in the dense seagrass meadows adjacent to mangroves and result in a higher soil OC concentration at the interface between mangrove and seagrass.” (6)
- Seagrass meadows located near mangroves or land edge tend to be richer in organic carbon than offshore meadows. (7)
