  • 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.

Conservation

Threats and measures

Aufgabe der traditionellen Beweidung


Weiterführen der traditionellen Alpwirtschaft mit mehreren Lägern auf den Alpen im Avers
Bewirtschaftungsbeiträge

Rasche Verdrängung der Art nach dem Ende der Beweidung (viel Stickstoff, kein Frass mehr)


Weiterhin beweiden
sonst als Pflegemassnahme mähen

Aufgabe der Benutzung der Viehwege


Traditionelle Viehwege weiter nutzen
evtl. alternativ durch Pferde, Schafe oder Ziegen

Wegbau, Strassenausbau u. a.


Rücksicht auf die Fundstellen im Talboden nehmen

Wenige, isolierte Populationen


Pflanzenschutzgebiet im ganzen Avers inklusive dem oberemVal Bercla schaffen (viele sehr seltene Arten)
Bestandeskontrollen
Dauerflächen-Beobachtung
Erfolgskontrolle der durchgeführten Massnahmen
