To better understand opportunities to build resilience in the Welsh marine environment, Natural Resources Wales commissioned a report to identify potential spatial opportunities to restore valuable marine habitats.

The report created spatial products (Arc Geo database) for: areas in the floodplain that might be suitable for the creation of mudflat and saltmarsh through managed realignment and areas where the right conditions might exist for native oyster habitat and horse mussel bed restoration. The horse mussel data was provided from JNCC. The report also addresses restoration potential for Sabellaria alveolata reefs although no spatial data was created for this habitat and seagrass habitat, but this was provided as a map image from JNCC.

These spatial data layers should be considered as initial aides to identifying potential locations or areas but come with several limitations which have been discussed in the report. Any restoration projects should undergo further site validation and local engagement before proceeding with any specific site.

A variety of source data was used and merged to create a selection of GIS Layers listed in the abstract to identify spatial opportunities for restoration of marine and coastal habitats and species.
