7.1.5. Trockenwarme Ruderalflur

Onopordion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die Einheit umfasst Pflanzengemeinschaften, in denen hochwüchsige Disteln (Onopordum bis 3 m hoch, Cirsium, Echinops, Carduus usw.) und Beifussarten (Artemisia vulgaris, A. absinthium) vorherrschen. Diese wachsen unter günstigen Bedingungen sehr rasch heran und halten extreme Trockenperioden problemlos aus. Die Pflanzen wehren sich, insbesondere während Trockenperioden, mit ihrer stacheligen Bewehrung oder mit abweisenden Stoffen (z.B. ätherischen Ölen) vor Tierfrass. Das Onopordion etabliert sich auf nährstoffreichen Schutt- und Brachflächen, die älter als zwei Jahre sind. Skelettreiche, trockene Böden eignen sich vorzüglich, vorausgesetzt, dass sie auch reichlich Stickstoff zur Verfügung stellen. Mit Ausnahme des Cirsietum eriophori verlangt diese Einheit ein warmes und trockenes Klima und ist in Gebieten mit kontinentaler Klimatendenz (z.B. in inneralpinen Tälern) besonders gut vertreten.

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.
