Datganiad

How the map has been created: The map has been created by identifying the overall opportunity space for each management option under consideration, and then combining them into a single layer summarising the opportunities to reduce the risk of faecal coliforms entering the water column. The opportunities for the individual management types have been identified by the following process: Identify land likely to be used for grazing that is directly adjacent to water courses, including minor drainage channels. In these areas, there is an opportunity for fencing and/or planting of hedgerows to prevent direct access to the river by livestock. Within the land adjacent to watercourses identified above, identify land biophysically suitable for tree planting, and where there are no other constraints to woodland planting. In these areas, wooded shelter belts or riparian woodland can be established. This dataset was produced for NRW under contract by Environment Systems Ltd.

Gwybodaeth ychwanegol

Data gaps and limitations: National Phase 1 dataset is likely out of date in many places The model does not consider ground water The model does not consider urban areas or sewerage infrastructure as sources of faecal coliforms The model looks at intercepting the transport of faecal coliforms into waterbodies, but does not consider opportunities to reduce input of faecal coliforms at point source.
