Protection status
| No international, national or cantonal protection |
- 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
Habitatverlust
Stillgewässer in Auengebieten anlegen.
Kiesgruben nach Aufgabe der Nutzung erhalten.
Mangel an Dynamik in aquatischen Lebensräumen
Eine natürliche Gewässerdynamik wiederherstellen, die Pionierlebensräume generiert und dafür mehr Raum bereitstellen.
Gewässereutrophierung
Für oligotrophe Verhältnisse (der Stillgewässer und Zuflüsse) sorgen. Die Nährstoffkonzentration auf einem oligo- bis mesotrophen Niveau halten.
Im Uferbereich breite Pufferstreifen mit Sumpf- und Gebüschzonen, Hecken- und Waldstreifen usw. erhalten.
Verhindern, dass grosse Nährstofffrachten über Oberflächenabflüsse, Drainagen usw., ins Gewässer gelangen.
Sowohl im Einzugsgebiet als auch in der unmittelbaren Umgebung des Gewässers eine extensive Bewirtschaftung mit den Instrumenten der Landwirtschaftspolitik fördern.
Wissenslücken
Die Entwicklung bekannter Bestände überwachen und mehr ökologisches Wissen über die Art in Erfahrung bringen, insbesondere über ihre Vermehrung und deren Abhängigkeit von der Temperatur.
