BIOGEOCHEMICAL CONSEQUENCES OF FORESTED COASTAL WETLAND RETREAT
Forested coastal wetlands provide important ecosystem services and are vulnerable to land use and global climate change. There has been significant research on the ability of marshes to keep up with sea level rise and their potential to migrate inland. However, we still lack a clear understanding of the biogeochemical consequences of forested wetland retreat associated with marsh inland migration. Based on our ongoing work and a literature review, we examined rates of sediment accretion and carbon and nitrogen accumulation in forested wetlands and marshes along the Atlantic coast of the US. We found higher and more variable accretion rates in marshes (4.65 ± 5.15 mm/year) than in forested wetlands (2.17 ± 0.83 mm/year). While analyses of C and N accumulation rates are still ongoing, results to date show little difference in C accumulation across wetland states, but higher N accumulation in marshes. Our results suggest that forested coastal wetlands are more vulnerable to sea level rise than marshes, and that accelerated sea level rise will alter the provision of ecosystem services provided by coastal landscapes.
