Terrestrial Phase 1 Habitat Survey

Natural Resources Wales

This dataset holds comprehensive habitat cover data for the whole of Wales derived from a programme of field recording that was begun by the Wales Field Unit of the Nature Conservancy Council in 1979 and continued by the Countryside Council for Wales after restructuring in 1991. The purpose of this data capture was to inform site selection, casework and policy decisions. The fieldwork was conducted in two main stages. Most upland areas were surveyed during the first stage (the Upland Vegetation Survey), and areas were assigned to habitat types using the Ratcliffe and Birks classification. The rest of Wales including all the lowlands and some previously unsurveyed upland areas was covered during the second stage (the lowland phase), and habitats assigned to the Phase I classification, with some minor modifications adopted for use in Wales.

This datasets contains the following layers:

  • Vegetation Voronoi: Showing the boundaries and attributes of vegetation polygons with upland mixed habitat polygons subdivided into their component habitats
  • Habitat: Point data showing the location of habitats mapped in mixed habitat polygons during the Upland Vegetation Survey
  • Mospolys Voronoi: A grid coloured in chequerboard fashion according to Phase1_Code and in proportion to their extent to enable the visualisation of mosaics
  • Mosnotes Varanoi: Point data to describe habitat composition of mosaic polygons
  • Scattered Vegetation: point data showing the location of scattered vegetation
  • Target Notes: record the position and reference number of Phase 1 target notes
  • Mosaic Voronoi: Browser table to supply habitat types, areas and proportions for mosaic polygons
