The original field surveys were carried out as part of a national habitat survey programme required to implement conservation at a local level. This dataset is an all - Wales, electronic dataset 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. Uniformly distributed scattered vegetation is also captured as a polygon attribute in the vegetation layer.

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). Methods for the lowland survey followed the Handbook for Phase 1 Habitat Survey with some minor modifications adopted for use in Wales (Howe E.A. and Blackstock T.H. (1991) Supplementary Notes for Phase I Survey in Wales. CCW, Bangor). All field mapping was carried out by trained and closely co-ordinated teams of surveyors. A study of survey reliability was conducted during the lowland phase (Kerry, Rimes, Smith, Williams. 1994. An Assessment of Errors in Phase I Habitat Survey in Wales. Bangor: Countryside Council for Wales, Report No. 94/4/1). It showed the field mapping to be 83% repeatable (Stevens, Blackstock, Howe, Stevens. 2004. Repeatability of Phase 1 habitat survey. J. Environ. Manage. 73, 53-59).The electronic data have undergone a series of checks for accuracy both by the contractor and subsequently within CCW. The Field survey spanned from 1979 to 1999.
