Abstract:
Globally, wetlands store vast amounts of carbon due to their unique hydrology and biogeochemistry. Unfortunately, forested wetlands are poorly represented in monitoring networks such as Ameriflux and the North American Carbon Program (NACP), and key processes that control belowground C cycling are not fully incorporated into process-based or ecosystem models. Further, forested wetlands in the South have been less-well studied than their northern counterparts but are extremely vulnerable to rising sea-level, extreme storm events, and increasing winter/summer temperature. We propose to use our existing set of fully instrumented eddy covariance towers located in young and mature drained pine plantations and an un-drained natural forested wetland to improve understanding of controlling mechanisms of belowground carbon cycling, and their sensitivity to environmental drivers as affected by climate change and sea-level rise. Findings will be used to improve representation of belowground processed in forested wetlands in ecosystem models that will be linked to larger-scale regional models such as CLM to estimate the impacts of climate change and SLR on regional C dynamics.
