Art. 19

The gathering of wild plants and capturing of animals living in the wild for commercial purposes are subject to approval by the competent cantonal authority. Such approval may be restricted to particular species, areas, seasons and quantities or numbers, or in other ways, and organised gathering or capturing activities and the promotion thereof may be prohibited. The foregoing does not apply to normal agricultural and forestry exploitation, or to the collection of conventional amounts of fungi, berries, and herbs used in teas and for medicinal purposes, unless the species in question are protected.
