  • 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

Populations restreintes et isolées

Protéger toutes les stations (micro-réserves)
Effectuer des contrôles des populations réguliers (Monitoring)

Entretien des bords de chemin inadapté (fauche trop précoce)

Ne faucher qu'après la formation des graines de l'espèce (espèce annuelle, il est donc impératif de la laisser produire des graines)
Marquer l'espèce avant l'entretien
Prendre en compte et sensibiliser les exploitants lors de la planification de l'entretien

Destruction de l'habitat (aménagement)

Prendre en compte l'espèce lors de projets
Interdire les permis de construire dans les stations actuelles de l'espèce
Etudier en cas d'urgence la possibilité de transplanter une population

Modifications des pratiques agricoles (fermeture du milieu)

Maintenir une utilisation favorable
Débroussailler si nécessaire
