Conversion of the EBR boundaries from the EBRs (vector) to the GB-EBRs (raster) map in two different geographical zones. Top row: Pyrenees - (a) Vector boundaries of Alpine, Atlantic, Continental and Mediterranean biogeographical regions, (b) 10 km × 10 km cells that overlap two or more biogeographical regions, (c) comparison between the vector boundaries and the new grid-based ones in the GB-EBRs map. Bottom row: Caucasus - (d) Vector boundaries of Alpine, Anatolian, Steppic biogeographical regions plus ‘outside data coverage’, (e) 10 km × 10 km cells that overlap two or more biogeographical regions, (f) comparison between the vector boundaries and the new grid-based ones, reshaped in the GB-EBRs map.
