For the sake of simplicity, a distinction is not made between the Bohemian Forest (originally the Inner Bavarian Forest) and the Bavarian Forest. Instead, the common local name of Bavarian Forest is used for the entire area of the low mountain range on the German side, as the term Bohemian Forest has become synonymous with the areas in the Czech Republic. A distinction is only made between the Anterior Bavarian Forest and the High Bavarian Forest, with the lineament of the Bavarian Pfahl being regarded as the boundary line between them. In the north-south direction, a distinction is made between the Upper and Lower Forest.
