Tidal marshes are susceptible to climate change, especially sea level rise (SLR). Changes in tidal marsh area and habitat type may be modeled using the Sea Level Affecting Marshes Model (SLAMM). This simulates the dominant processes involved in wetland conversion and shoreline modification under different scenarios of sea level rise.  In 2012 the NH Fish and Game Department and the Great Bay National Estuarine Research Reserve, completed a first run of the Sea Level Affecting Marshes Model. In 2014 that model was improved with new input data and the results will be evaluated through a wildlife habitat condition analysis. Goal: to guide conservation strategies that will protect the coastal wetland areas that are likely to provide high quality wildlife habitat and persist for the longest duration. SLAMM outputs at 25-year intervals through 2100 are available at 0.5 meter, 1.2 meter, and 2 meter Sea Level Rise scenarios. Note that inland wetlands were removed for simplified display purposes.
