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

Entwässerung, Meliorationen


Moorflächen mit Fundorten unbedingt als Ganzes und in intaktem Zustand erhalten
verhindern einer schleichenden Entwässerung

Eutrophierung


Grosse Pufferzonen ohne Düngung schaffen
Bewirtschaftungsverträge in den Randzonen, keine Bewirtschaftung in den Kernzonen

Tritt (die Art und ihr Lebensraum reagieren sehr empfindlich auf Trittbelastung, die Art ist sehr schwer zu sehen), Sammeln


Striktes Betretverbot für alle Fundgebiete (auch für Pflanzenliebhaber)
Hinweistafeln zum Naturschutzgebiet

Bautätigkeit (touristische Anlagen, Strassen, Leitungen)


Priorität für die noch existierenden Lebensräume

Beweidung


Keine Beweidung
einzäunen falls Moorflächen noch beweidet werden (dafür zukünftig entbuschen sofern notwendig)

Kleines Areal, isolierte Populationen


Schutz aller Fundorte gewährleisten (bestehende Naturschuzgebiete)
Bestandeskontrollen ca. alle fünf Jahre (nur durch Personen, welche die genaue Lokalität der Pflanzen kennen)
Ex situ-Vermehrung mit Brutknöllchen versuchen (Erhaltungskultur)
Dauerflächen-Beobachtung an einem Fundort
populationsbiologische Untersuchung initiieren
Erfolgskontrolle der Massnahmen gewährleisten

In-situ measures
