Summary
Model projections of mangrove species' relative composition (0-1) under low, moderate, high, and extreme (37, 52, 67, and 117 cm by 2100) sea-level rise. Species cover was modeled as a function of annual inundation time, using field observations of species occurrence and elevation to define species-specific zone of suitable habitat. Soil elevation changed in response to mineral and organic matter inputs and relative changes in sea-level. The model was calibrated using dated soil cores, extensive elevation and vegetation survey data, and water level observations around Pohnpei. Relative species composition values were output in 20 year intervals from 2020-2100. Further details on model development, calibration, and validation are provided [...]

These data are results from a model of mangrove species response to sea-level rise across different regions of Pohnpei. They can be used to compare the relative vulnerability of species to different amounts of sea-level rise.
