Anatomy
Summary of leaf anatomy (German)
Obere Epidermiszellen grösser als untere. Punktuelle Versteifungselemente am Blattrand und bei der Blattrippe. Verbindungs-Steg zwischen oberer und unterer Epidermis homogen verholzt. Leitbündel im Verbindungs-Steg unten eingebettet. Leitbündelhülle verholzt.Summary of stem anatomy (German)
Umriss rund oder oval. Leitbündel in mehreren Reihen. Konische Stützen. Grosse, unregelmässige Intercellularen. Epidermiszellen aussen verholzt.Description
Culm-diameter 1-2 mm, wall very large, radius of culm in relation to wall thickness approximately 1: 0.75. Culm-center hollow and surrounded by many large thin-walled, not lignified cells. Epidermis cells inside thin, peripheral thicker-walled (lignified). Guard cells with externally acute ledge. Large vascular bundles arranged in 2-3 peripheral rows. Chlorenchyma absent. Sclerenchyma belt absent. Groups of sclerenchyma square or rectangular. Vascular bundles collateral closed. Small sclerenchymatic sheath around vascular bundles with 1-2 cells. Largest vessel in the bundle small, < 20μm. Cavities (intercellulars) between parenchyma cells absent. Distinct cavities (intercellulars) in the protoxylem area of vascular bundles. Cell contents as slime or phenols in isolated cells.Distribution map (Atlas)

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
Lebensraumzerstörung, Meliorationen, Eingriffe in den Wasserhaushalt
Vermeidung einer stärkeren Änderung des Wasserhaushaltes, falls nötig Regulierung des Wasserstandes (durch Unterhalt und Regulierung der bestehenden Rietgräben)
je nach Gebiet auch Wiedervernässung prüfen
Bau von Verkehrsanlagen, Industriebauten, Golfplätzen und Siedlungen
Vorrang der wertvollen Lebensräume vor Bauprojekten
Eutrophierung
Düngungsverbot auch in der Umgebung

Entbuschen
ausholzen
Streuenutzung weiterführen
Bewirtschaftungsverträge abschliessen.
Selektives Entfernen der Gehölze samt Wurzelwerk mit Kleinbaggern unter Schonung der Begleitvegetation
Lokale Nährstoffkatastrophen (Überflutung mit eutrophem Wasser)
Massnahmen zur weiteren Nährstoffreduktion in den benachbarten Gewässern durchführen
Mechanische Einwirkungen durch Freizeitaktivitäten (z. B.Tritt, Photographieren)
