The Rüf company has plans to mine gravel at the foot of the Kanisfluh. Gravel mining does not present a problem for state geologist Eva Vigl, as one would only scratch the surface and the Kansisfluh would not become destabilized. The municipality of Schnepfau, however, wants to prevent the mining of 800,000 m³ of stone over the next 30 years. The state authority is reviewing if Schnepfau may put the area under nature preservation. In the discussion about the gravel mining at the foot of the Kanisfluh, the Greens argue for putting the Kanisfluh under large-scale nature preservation.An intervention like the gravel mining would be a permanent wound in the natural scenery and is therefore impermissible. In addition, the Kanisfluh is the asset for the tourism in the Bregenz Forest.
