7.1.8. Lägerflur der Tieflagen

Arction

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Diese Gesellschaften bilden hochwüchsige Staudenfluren (1 bis 2 m), in denen breitblättrige zweijährige und ausdauernde Stauden (Arctium, Rumex, Phytolacca) vorherrschen. Die nährstoffliebende Vegetation besiedelt mässig frische, feinerdereiche Böden, die sehr nährstoff- und vor allem sehr stickstoffreich sind. Die Hüllblätter der Kletten (Arctium) besitzen Häkchen, die ihre Verbreitung durch vorbeiziehende Weidetiere von einem Lägerplatz zum anderen erleichtern. Wie das Onopordion (7.1.5) ist das Arction eher wärmeliebend, aber weniger gut an Trockenheit angepasst. In den trockenen Regionen der Schweiz gedeihen diese Gesellschaften deshalb eher im Halbschatten, wo die Verdunstung geringer ist. Die Einheit siedelt hauptsächlich in den tiefen und mittleren Höhenlagen. An geschützten Orten mit günstigem Mikroklima erscheint sie aber auch in der subalpinen Stufe.

Distribution map

  • Calculation method

    Current distribution: Weighted sum (number of characteristic and frequent species) per hectare based on current observations. Reported characteristic species are given a weighting of 10, while others are counted without weighting. The habitat is considered to be present in a grid cell (5 x 5 km) if it contains at least one hectare with a minimum value of 11 points.

    Potential distribution: Weighted sum (number of characteristic and frequent species) per hectare based on species distribution models. The calculation strategy is the same as for current distribution, but maps derived from species distribution models are used instead of current observations.
