  • Disclaimer
    InfoFlora compiles information on protected species as accurately as possible, taking it from the respective cantonal laws. In some cases, however, it was not possible to use the plant names as listed in the original text, but an interpretation of their taxonomy or nomenclature was necessary. The exact meaning of the categories „completely protected“ and „partially protected“ differs among the cantons.

    InfoFlora cannot guarantee that the information on the protection status is correct and complete. In case of doubts, we recommend to look up the texts of the respective cantonal law.

Threats and measures

Intensive Nutzung aller Flächen, fast keine extensiv genutzte Felder oder Brachen mehr

Ackerschonstreifen und Buntbrachen fördern
Umbruch nur alle 2-4 Jahre

Mehr Bearbeitungsgänge, zu kurze Brachzeiten

Längere Brachzeiten zulassen

Verbesserte Saatgutreinigung, zu hohe Saatdichte des Getreides

Anbau von alten Kultursorten
lockerere Einsaat

Umwandlung von Getreide- zu Maisanbau

Erhaltung und Förderung des extensiven Getreideanbaus

Herbizide (Landwirtschaft und entlang Eisenbahn), Gleisunterhalt

Keine Herbizide in Brachen und Randstreifen, weniger entlang Bahnlinien
Information der SBB bezüglich der Fundstelle beim Bahnhof Turtmann

Wenige, isolierte Populationen

Schutz der Fundgebiete bzw. Auflagen für die Nutzung (Mikroreservate)
regelmässige Bestandeskontrollen
Wiederansiedlungen mittels Buntbrachen (Saatgut, Verlauf protokollieren)
Erfolgskontrollen der Massnahmen gewährleisten
