- 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
Erneuerung der Gräben (Betonierung, ”Reinigung”, Verschüttung)
Aktuelle Fundstellen unbedingt erhalten
Verkrautung, Sukzession
Zuwachsende, aber ansonsten günstige Gräben offenhalten
extensiv mit Mähmaschine befahrene, offene Stellen weiterhin in dieser Art ”stören”
Austrocknung
Neuschaffung pionierartiger, etwas vertiefter Lebensräume (nur in weniger wertvoller Vegetation)
Eutrophierung (direkt, via Luft, via Strasse, Überschwemmungen)
Massnahmen gegen Eutrophierung des Sees weiterführen
Pufferzone einrichten
Tritt
Falls notwendig abzäunen
Hinweisschilde
Bauvorhaben, Lehrpfade etc.
Priorität der Fundstellen vor Bau- und Freizeitvorhaben
