Approximate distribution of HNV farmland in EU-27
Estimate based on land-cover data (Corine, 2000) and additional biodiversity datasets with varying base years (roughly 2000–2006). Resolution: 1 km2 for the land-cover data, down to 0.5 ha for additional data-layers. The figures in the map (green shades) correspond to estimated coverage of HNV farmland within 1 km2 grid-cells. Because of the error margins in the interpretation of the land-cover data, these figures are best treated as probabilities of occurrence rather than land‑cover estimates. Occurrence of HNV farmland in the pink, purple and orange areas is most certain, since these delineations are based on actual habitat and species data.
