Bringing Wetlands to Market: BWM Wetland GHG Model

Coastal managers can use this Excel® spreadsheet file to estimate the potential carbon storage of a wetland region.

Research indicates that coastal wetlands might capture and store carbon at rates three to five times greater than forests. Research also suggests that nitrogen pollution from septic systems, stormwater runoff, and airborne pollution can significantly compromise a wetland’s ability to store carbon.

The model uses inputs for photosynthetically active radiation, soil temperature, soil salinity, water depth related to marsh surface, and net lateral flux over the growing  period. Outputs include predicted CO2 flux, predicted CH4 emission flux, total CO2 sequestration over the growing period, total CH4 emission over the growing period, net ecosystem carbon balance over the growing period, and net ecosystem carbon balance over the growing period.
