Forest ecosystem between the industrial regions of the Saarland and Lorraine

The sub-area is located between the valley of the river Saar in the northeast and the industrial region of Lorraine.

The predominant soils in this area are periglacial floating soils of fine sands which are characterized by a low sorption capacity and high contaminant burdens. They are not suitable for agriculture. Instead the sub-area is covered by a large forest of beech, oak, spruce, pine, and larch with only three small towns (i.e., Ludweiler, Differten, and Lauterbach) and a few abandoned coal mines.
