The Swiss Ephedra (Ephedra distachya ssp. helvetica) is a primeval plant and is considered as endemic in the Western Alps. In the Upper Valais it grows only on three sites. Here in Niedergesteln the small population has been endangered due to the overgrowing by the Savin Juniper (Juniperus sabina). With targeted measures realized by volunteers during a work program of the World Heritage site management, the preservation of this population should be guaranteed.
