Service Description: 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). The model simulates the dominant processes involved in wetland conversion and shoreline modification under different scenarios of sea level rise. In 2014 the NH Fish and Game Departmentand the Great Bay National Estuarine Research Reserve, completed a first run of SLAMM. In 2022 that model was improved with higher resolution habitat, LiDAR, and updated parameters. The goal is to guide conservation strategies that will protect the coastal wetland areas that are likely to provide high quality habitat and persist for the longest duration.
