The dataset can be used to support the identification of areas suitable for NFM alongside other analyses undertaken by a suitably qualified person. The information provided is based on a national scale mapping approach, taking into account largely modelled and open-source data, therefore this mapping should be viewed as indicative rather than specific. Locations identified may have more recent building or land use than available data indicates. It is important to note that land ownership and change to flood risk have not been considered. This prioritisation has been based on an existing dataset highlighting catchments with a “Demand for Natural Flood Management”. These catchments were derived as part of the System Cynorthwyo Cunllunio Adnoddau Naturiol (SCCAN) maps created by Natural Resources Wales.  These larger catchments above communities at risk from fluvial flooding are prioritised based on the percentage area of NFM potential as identified in two mapping sources, the Working with Natural Processes (WwNP) potential area maps and the System Cynorthwyo Cunllunio Adnoddau Naturiol (SCCAN) maps. The potential for the following features was summarised in the prioritisation: Floodplain reconnection potential (WwNP) Wider catchment woodland planting (WwNP) Bog restoration (and restoration on common land) (SCCAN) Opportunity to improve habitat condition – High priority (SCCAN) Opportunity involving habitat change – High priority (SCCAN) Opportunity for retention of winter stubbles in area at greater risk of flooding (SCCAN) The following features were given a double weighting for potential ecosystem service provision based on an analysis of the WwNP Evidence Directory: Riparian Woodland (WwNP) Infiltration improvements on slowly permeable soils (WwNP) Hedgerows (SCCAN) Bog restoration (SCCAN) The catchments have been categorised based on the percentage area of NFM potential of: <10% 10%-25% 25%-50% >50%   2025-02-18 Water and Flood Division Water and Flood Division en Other Restrictions geonode:pmfnfm_large_catchments_env_weighting EPSG:4326 51.37098690534847 -4.848571457542868 53.44235017614119 -2.520764520062577
