A recent publication in the journal Carbon Balance and Management, entitled A carbon balance model for the great dismal swamp ecosystem, uses ST-Sim to assess the historical changes in the net ecosystem carbon balance for a critical 54,000 ha wetland in North Carolina and Virginia. The study, conducted by Rachel Sleeter and others at the U.S. Geological Survey, concludes that changes in the wetland’s carbon balance over the past 30 years, as a result of emissions due to recent fire and storm events, are essentially irreversible over a management timeframe.  Future applications of this model will explore alternative land management scenarios for sequestering additional ecosystem carbon, such as the rewetting of large portions of the wetland.
