- 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
Natürliche Seeuferabschnitte erhalten.
Naturferne Abschnitte renaturieren, u.a. indem Blockwürfe durch kiesige und sandige Substrate ersetzt werden.
Mangel an Dynamik in aquatischen Lebensräumen
Erhalten oder Wiederherstellen von Wasserstandschwankungen im Litoral. Sie sind für die Entwicklung der Art von Vorteil: Niedrigwasserstände in Herbst und Winter, Hochwasserstände in Frühling und Sommer.
Gewässereutrophierung
Erhalt der physikalisch-chemischen Qualität der Gewässer (Seen und Zuflüsse). Den Nährstoffgehalt auf tiefem Niveau halten (oligo- bis mesotrophe Verhältnisse).
Breite Pufferzonen im Uferbereich anlegen, aus amphibischen Bereichen, Gebüsch- und Gehölzstreifen, Waldrändern.
Verhindern, dass Abwassereinleitungen, Abschwemmungen, Entwässerungen in die Litoralzone fliessen.
Gräben zum Abfangen solcher Störeinflüsse anlegen
den Zufluss vor dem Abfliessen natürlich reinigen und ausserhalb des Litorals ins Gewässer einleiten.
Im Einzugsgebiet und um die Kleingewässer eine extensive Bewirt-schaftung mit den zur Verfügung stehenden Instrumenten der Landwirtschaftspolitik fördern.
Wissenslücken
Mehr Wissen über die ökologischen Ansprüche der Art und ihre Verbreitung in Erfahrung bringen.
Die Entwicklung bekannter Bestände überwachen. Dies gezielt, um mehr über die bestimmenden Umweltbedingungen zu ihrer Entwicklung und ihrer Fortpflanzung zu erfahren..
Die Bestände im Jura und Graubünden genetisch abklären und ihr Verhalten in Bezug auf einwirkende Umweltbedingungen untersuchen, insbesondere auf Temperaturänderungen.
