4.1.3. Wärmeliebende Silikatfels-Pionierflur

Sedo-Veronicion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Der Bewuchs dieser Lebensräume ist niederig und lückig und besteht wie beim Alysso-Sedion (4.1.1) hauptsächlich aus Therophyten und Fettblattgwächsen. Im Thero-Airion sind noch einige grasartige Annuelle enthalten. Die Einheit gedeiht in den tiefen Lagen, wo klimatisch ähnliche Bedingungen vorherrschen wie bei den Kalkfels-Pionierfluren. Auch hier beginnt die Wachstumszeit zeitig im Frühjahr, gelegentlich kann eine zusätzliche Blühphase Anfang Sommer stattfinden. Das Substrat setzt sich aus einer dünnen Schicht Sand und Ton zusammen, oft am Rand der Felsplatten, im Übergang zu Rasen. Der stets kalk- und meist auch nährstoffarme Boden trocknet während der Sommerzeit völlig aus.

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.
