  • 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

Torfabbau, späte Auswirkungen früherer Torfstiche (v. a. Austrocknung)


Kein Torfabbau
Wasserhaushalt stabilisieren und an einigen Fundstellen lokal vernässen

Natürliche Sukzession


Vorsichtige Reduktion von Konkurrenzpflanzen, jedoch Schonung anderer seltener Arten.
In Nachbarschaft der Fundstelle(n) flache Mulden schürfen: Auspflanzungen aus Ex situ-Vermehrung.

Beweidung, Eutrophierung


Einzäunen
grosse Pufferzonen

Verbuschung, Verwaldung


Offenhalten der Moorfläche, entbuschen

Wasserstandregulierung


Natürliches Wasserregime erhalten

Wenige, isolierte Populationen (gestörte Populationen lassen sich sehr schlecht regenerieren)


Schutz inkl. grossen Zonen mit gutem Pufferungsvermögen
regelmässige Bestandskontrollen
Dauerflächen-Beobachtung
Detailkartierung der Vorkommen mit der Methode PopCount
ex-situ-Vermehrung als Erhaltungskulturen
Erfolgskontrollen der Massnahmen gewährleisten. Verstärkung bestehender Populationen und Ansiedlung neuer Populationen durch Anpflanzung (nach Zwischenvermehrung)

Ex situ material

In-situ measures
