  • 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

Änderung des Wasserhaushaltes, besonders Entwässerungen, Änderung Wasserchemie durch Drainage benachbarter Flächen.


Wasserhaushalt und Wasserchemie optimieren. Am besten sind hangwasserbeinflusste, wintermilde, kalkarme Standorte.

Intensivierung, Aufgabe traditioneller Bewirtschaftung (z. B. Streunutzung)


Erhaltung extensiv genutzter Wiesen und Weiden
traditionelle Nutzungen beibehalten (Ökobeiträge)

Verbuschung, Beschattung, Verschilfung


Entbuschen
Mahd von Hand im Hochsommer (die niedrigwüchsige Art wird davon selbst nicht betroffen). Mahdgut wegführen.

Sukzession, dichterer Rasenschluss (z. T. durch Mahd)


Schaffen und Unterhalt von geeigneten Ersatzstandorten in der Umgebung der Fundstelle (auch bei ehem. Vorkommen)

Konkurrenz durch andere Arten


Reduktion der Konkurrenten von Hand

Direkte Gefährdung des aktuellen Standortes


Vorsicht bei Pflege- und Unterhaltsarbeiten, z. B. keine Vergrösserung des Teiches

Eutrophierung (evtl. auch Sickerwasser aus der Umgebung)


Genügend grosse Pufferzone einrichten

Einzige, isolierte kleine Population


Ex situ Vermehrung und Wiederansiedlung beim aktuellen Fundort und an weiteren ehemaligen Fundstellen (Minimierung des Aussterberisikos, diese Arbeiten sind bereits erfolgreich angelaufen, s. unten)
Erfolgskontrolle der Massnahmen gewährleisten

In-situ measures
