Palatine Watershed
In the southern Palatine Forest, the German part of the Wasgau, the Palatine Watershed begins on the French border in the area of the Erlenkopf hill (473 m above NHN), where it is a continuation of the watershed in the northern Vosges. Always generally running from southwest to northeast it initially heads eastwards past Eppenbrunn and Pirmasens over the Großer Schiffelskopf () and reaches the region of Gräfenstein Land. From there it runs up the Hortenkopf () in the central Frankenweide. Several kilometres it passes through the hamlet of Johanniskreuz (), one of the highest settlements in the Palatine Forest. The watershed then reaches the area west of Waldleiningen in the Lower Frankenweide.
Palatinate Forest
The Palatinate Forest Nature Park was recognized in 1992 by UNESCO as a biosphere reserve. In 1998 it became the German part of the first cross-border UNESCO biosphere reserve, namely the Palatinate Forest-North Vosges Biosphere Reserve. It thus became the 12th of (as at 2009) 15 German biosphere reserves. These are areas that have a special significance for the global conservation of biological diversity and in which the ecological aspects, sustainable economic management, environmental education and environmental research are best linked together.
