- 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
Umwandlung von Getreide- zu Maisäckern
Förderung extensiver Getreideäcker (z. B. mit alten Kultursorten)
Intensivierung der Landwirtschaft (v. a. starke Düngung und Herbizide), grosse Parzellierung
Verzicht bzw. starke Reduktion von Herbizideinsatz und Düngung
kleinparzellierte Flächen beibehalten
Buntbrachen und extensive Randstreifen schaffen (Ökobeiträge)
Zwiebelgeophytenfeindliche Bewirtschaftung der Rebberge: dichte Grasuntersaat, tiefe Bodenbearbeitung, häufiges Mähenund Mulchen, Herbizide schon im Frühling
Eingriffe (auch Herbizide) nur in Ruhephase von Juni-Oktober
«unsauberes» Hacken alle 2 Jahre (offener Boden < 70%), max. 10-15 cm tief
Mähen und Mulchen max. so häufig wie für das Gedeihen der Reben unabdingbar (Integrierte Produktion oder BIO-Rebbau)
Umwandlung der Hochstamm-Obstgärten
Erhaltung und Schaffung von Hochstamm-Obstgärten
Wenige, isolierte Populationen
Schutz (Mikroreservate)
regelmässige Bestandeskontrollen
Dauerflächenbeobachtung
Ex situ-Vermehrung in Botanischen Gärten
Verstärkung von kleinen Populationen und Ansiedlung von neuen Populationen (nach Zwischenvermehrung)
Erfolgskontrolle der Massnahmen gewährleisten
