| 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
Kleine flache Stillgewässer anlegen (Teiche, Tümpel und Wassergräben).
Vorzugsweise neue Lebensräume in der Nähe von altbekannten Fundorten anlegen, ansonsten unweit von Fliessgewässern, in ehemaligen oder aktuellen Moorgebieten.
Hohe Wassertemperaturen
Mangel an Dynamik in aquatischen Lebensräumen
Wiederherstellen einer natürlichen Dynamik mit mehr Gewässerraum, wodurch Pionierstandorte in Auengebieten geschaffen werden.
Falls eine natürliche Dynamik fehlt, dann ist ein periodisches Bereitstellen von Pionierflächen notwendig. Die Massnahmen müssen -gestaffelt in Raum und Zeit- nach dem Rotationsprinzip vorgenommen werden.
Gewässereutrophierung
Die physikalisch-chemische Wasserqualität in den besiedelten Gewässern erhalten. Nährstoffarme bis mässig nährstoffreiche Gewässer (oligo- bis mesotrophe Verhältnisse) sind für alle Characeen vorteilhaft.
Anlage von breiten Pufferzonen um Kleingewässer zur Begrenzung diffuser Nährstoffeinträge.
Wissenslücken
Mehr Wissen über die Verbreitung und die Ökologie der Art in Erfahrung bringen.
Bereits ab März Tümpel, Weiher, Kleinseen und Sümpfe absuchen, besonders neu angelegte Gewässer, um mögliche neue Vorkommen in der Schweiz zu entdecken.
Endgültiges Verschwinden
Wiederansiedelung der Art in neu geschaffenen Gewässern, möglichst nahe an alten Fundorten.
Dabei auf die europäische Samenbank (mit Sedimenten aus bekannten Wuchsorten) zurückgreifen.
