Grazing Marsh Phase 1 Habitat Data (Derived from Phase 1 Terrestrial Habitat Survey)

This is a spatial dataset based on the Habitats of Wales Phase 1 data (1979-1997) it shows updated phase 1 polygons for Grazing Marsh and Floodplain Grasslands for Wales extracted from the all Wales Phase 1 digitisation. This was used to produce an inventory of the priority UK Biodiversity Action Plan (BAP) habitat grazing marshes and flood plains for all Wales see metadata entry 99333.

Lineage

Extracted from the all Wales digitisation of the 1979 to 1997 Phase 1 data. OS Landline was used as a backdrop and polygons were captured individually. The data was clipped against the site boundaries layer (see separate metadata entry). This dataset supersedes the original grazing marsh phase 1 data taken from the Inventory and Review of Grazing Marsh and Floodplain Grasslands. Due to lack of base-mapping and logistics the original boundaries were traced as contiguous habitat blocks onto tracing paper, then captured by scans using a raster to vector conversion tool, resulting in spatial accuracy implications. This updated dataset has improved significantly on the accuracy of the original.
