- 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
Eutrophierung (Landwirtschaft, Fischerei mit Fütterung und Kalkdüngung), Wasserverschmutzung, Algenbildung
Massnahmen zur Reduktion des Nährstoffgehalts in den Seen weiterführen, grosse Pufferzonen einrichten, Wasserverschmutzung verhindern
Freizeitaktivitäten (Boots-, Badebetrieb, Angeln)
Schutzzonen definieren, Lenkungsmassnahmen einleiten
Ausbleibende Neubildung von Altwässern, natürliche Sukzession
Durch Renaturierung vermehrt natürliche Dynamik in Flusstälern fördern (aktuelle Vorkommen schonen)
periodisch geeignete Lebensräume schaffen (Weiherbiotope)
Entwässerung, Trockenlegung oder Stauung
Keine negativen Veränderungen
Vermischung mit Pflanzen unbekannter Herkunft
Falls Ansiedlungen vorgenommen werden, diese nur mit Material bekannter, einheimischer oder grenznaher Herkunft (je nach Region) zulassen
Wenige, isolierte Populationen
Schutz inkl. Pufferzonen (z.B. Mikroreservate), regelmässige Bestandeskontrollen, Erfolgskontrolle der Massnahmen gewährleisten
