  • 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

Nutzungsänderungen (besonders Intensivierung oder Aufgabe der Beweidung)


Gegenwärtige Nutzung beibehalten
an einigen Fundorten Nutzungsintensität überprüfen
Randgebiete potentiell günstiger Sumpfwiesen und Flachmoore nahe aktueller Fundstellen extensiv beweiden (sofern mit anderen Schutzzielen vereinbar)

Sukzession


Besonders in Schutzgebieten (falls keine Beweidung) z. B. von Hand günstige erdigoffene Bereiche schaffen

Tritt


Falls Tritt zu stark etwas extensivieren
evtl. Zäune versetzen, damit das Vieh auch auf weniger nasse Bereiche ausweichen kann (aber etwas Tritt ist überlebenswichtig!)

Entwässerung, Strassenbau


Bestehende Fundstellen erhalten
allfällige Projekte anpassen

Eutrophierung


Direkte Einzugsbereiche nicht düngen
Pufferzonen einrichten

Z. T. kleine, isolierte Populationen


Schutz der Fundstellen (Mikroreservate)
regelmässige Bestandeskontrollen
ex-situ-Vermehrung veranlassen

In-situ measures
