All Wales Phase 1 Terrestrial - Habitat Layer

  • English

  • All

This is a spatial dataset containing point data showing the location of habitats mapped in mixed habitat polygons during the Upland Vegetation Survey. The habitat codes have been translated from Ratcliffe and Birkes to Phase 1. Corrections made in 2014 are: missing points added for Cothi Tywi and Mynydd Mallaen and Pwllpeirian, and points removed from single habitat and uniform mixed habitat polygons in Berwyn. This update was done when the voronoi version of the Phase 1 veg layer was created. The original field surveys were carried out as part of a national habitat survey programme required to implement conservation at a local level. An all-Wales electronic dataset was created for the generation of national statistics on habitat coverage. The dataset was subsequently imported into a GIS to enable its disaggregation into various different geographical regions within Wales.

Lineage

Field survey for the Upland Vegetation Survey spanned from 1979 to 1989. Closely co-ordinated teams of surveyors carried out field recording of habitats onto 1:10,000 scale maps (rarely 1:25,000 during the upland stage). The minimum size of habitat patch recorded lies predominantly within the range 0.1-0.25 ha, although smaller areas were mapped in the lowlands. The survey methods employed during the initial upland stage are given in more detail in a WFU report (Day, A. (1989) Upland Vegetation Survey 1979-1989 Background Methodology and Summary of Data Collected. NCC, Bangor). All field mapping was carried out by trained and closely co-ordinated teams of surveyors. Checks on the Upland Vegetation Survey data were carried out between 1994-1996 (Yeo, M. J. M., Blackstock, T. H. 2002. A vegetation analysis of the pastoral landscapes of upland Wales, UK. Journal of Vegetation Science 13, 803–816). The electronic data have undergone a series of checks for accuracy both by the contractor and subsequently within CCW.
