On the initiative of Deutsche Bahn, 600 sheep graze in the valuable meadows full of orchids in the Unstrut Valley. This is one of many accompanying landscape conservation measures designed to compensate for the encroachment into the natural environment caused by the construction of the Unstrut Viaduct, which is 2.7 kilometres long.
