The amalgamation of several major geographical units by the working group for Ecological balance and Regional Character at the Saxon Academy of Sciences in Leipzig, that includes a break-up of the old natural region of Oberlausitz, has not been fully recognised officially, because this division has not yet been accepted by federal authorities like the Bundesamt für Naturschutz (BfN), but does broadly follow the logic of other groupings such as that of the Thuringian-Franconian Upland which border it to the west and includes the Thuringian Forest, Thuringian Highland, Franconian Forest and Fichtelgebirge.
