  • 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.

Threats and measures

Sukzession; fehlende Dynamik, welche offene Stellen in Riedgebieten schafft (Überschwemmungen, extensive Beweidung, Befahren, Tritt, etc.)

Bestehende, punktuelle Störungen beibehalten
offene, pionierartige Stellen in wechselnassen Riedwiesen gezielt fördern
wissenschaftlich begleitete Versuche mit extensiver Beweidung durch Rinder als Pflegemassnahme durchführen (sofern nicht andere stark gefährdete Arten betroffen sind)

Düngung, Eutrophierung

Pufferzonen vergrössern oder einrichten
Düngeverbot

Konkurrenz, invasive Arten wie Goldruten und Adlerfarn

Invasive Arten früh bekämpfen (evtl. von Hand)

Nutzungsänderungen

Bewirtschaftungsverträge
meist Beibehaltung der gegenwärtigen oder Wiedereinführung der früheren Nutzung
teils extensivieren

Austrocknung, Entwässerung, Meliorationen

Nur «sanfte» Meliorationen
der Austrocknung entgegenwirken
evtl. Aufstau, jedoch wechselfeuchten Charakter beibehalten
Renaturierungsmassnahmen

Verbuschung, Beschattung

Entbuschen
benachbarte, die Bestände beschattende Baumreihen oder Gehölze teilweise auslichten

Beweidung, Tritt, Erosion

Bei zu intensiver Beweidung extensivieren
leichte Beweidung jedoch beibehalten
evtl. lokal einzäunen

Weg-, Strassenbau, Unterhalt, Überbauung

Auf Fundstellen Rücksicht nehmen
anpassen von Projekten bereits bei der Planung
