Karlsruhe bioregion

This base map shows the 50-kilometre radius that defines the Karlsruhe bioregion, with the Living Library at its centre. The region can be broadly divided into three areas: the Oberrheingraben/Upper Rhine Graben (framed by two fault lines indicated by dashed lines), a large rift valley formed about 50 million years ago with the river Rhine flowing northwards through its centre (double line); the Pfälzerwald/Palatinate Forest to the west; and the Schwarzwald/Black Forest to the east. The line pattern indicates elevation, revealing an almost flat Graben between two large mountain ranges. To reflect the region’s linguistic diversity, all cities on the map are written in both their local and national names.
