This dataset comprises of the outputs from geospatial model used to identify and map sites suitable for the creation of new saltmarsh habitat across the Scottish coast under current and future sea levels.
The work was carried as part of the ClimateXChange project (IQ20-201) - Blue carbon potential of Scottish inter-tidal wetlands and the implications of sea-level rise: policy brief.

The modelling approach utilised the latest open access LiDAR data for Scotland’s coastline in conjunction with regional tidal data (ntslf.org/) to identify sites suitable for managed realignment and to map the potential extent of high a low marsh. Across Scotland’s coast fifteen sites were identified largely across the major eastern estuaries. Future modelled sea levels were projected onto these sites to determine the potential loss of these newly created saltmarshes under future climate scenarios. Spatial models were created for five future sea level scenarios derived from the Met Offices UK climate projections (UKCP) these include the best-case scenario (RCP 2.6 - 5th percentile), worst case scenario (RCP 8.5 - 95th percentile) and the median (50th percentile) estimated sea level across the three core scenarios (RCP 2.6, 4.5, 8.5) for the years 2032, 2045 and 2100.
