Umriss rund oder oval. Leitbündel in einer Reihe. Epidermiszellen nicht verholzt.

Description

Culm-diameter 2-5 mm, center full, radius of culm in relation to wall thickness 1:1. Outline circular with a smooth surface. Culm-center full, containing unlignified cells. Culm without endodermis but with a sheath of lignified cells around the center. Epidermis cells thin-walled all around. Large vascular bundles arranged in 2-3 peripheral rows. Sclerenchyma belt in a large, peripheral continuous belt (> 3 cells). Cells thick-walled. Small sclerenchymatic sheath around vascular bundles with 1-2 cells. Vessel arrangement horseshoe-like. Largest vessel in the bundle 20-50 μm.

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

Aufgabe der traditionellen Mähnutzung, Konkurrenz von Molinia arundinacea


Bewirtschaftungsverträge
noch bestehende Mähnutzung unbedingt erhalten, Bestände sonst durch Pflegemassnahmen offenhalten (wie z. B. bei Cassina)
alle 2-3 Jahre im Herbst mähen
Mähgut wegnehmen
kein Abbrennen der Vegetation oder entfernen der Streu mit Rechen

Verbuschung, Beschattung


Entbuschen und an einigen Fundstellen
auslichten der feuchten Waldwiesen

Beweidung


Falls möglich Beweidung durch Wiesennutzung ersetzen
ansonsten nur angepasste, kontrollierte Beweidung und Bestand evtl. einzäunen (dann von Hand mähen, 1x jährlich)

Weg-, Strassenbau, Unterhalt


Auf Fundstellen Rücksicht nehmen

Z. T. ungenügender Schutz, Sammeln


Schutz der Parzellen (Ortsplanung oder private Schutzgebiete) z. B. am Monte San Giorgio verstärken, weiterhin gepflegte Naturschutzgebiete haben hier hohe Priorität (z. B. kommt auch Adenophora liliifolia vor)
zusätzliche Hinweisschilder zu Pflückverbot aufstellen

Kleine, isolierte Populationen


Ex situ-Vermehrung von Material aller Fundbereiche
evtl. später Wiederansiedlung
regelmässige Bestandeskontrollen
Detailkartierungen
erneute Suche bei «Pianche» ob Rovio
Erfolgskontrollen der Massnahmen gewährleisten

In-situ measures
