Herausragendes Merkmal dieser Einheit sind die Frühjahrs-Geophyten, die sich mit Sommerannuellen vergesellschaften. Diese Vegetation wächst in verschiedenen Hackfruchtkulturen, insbesondere aber in Rebbergen. Der Untergrund dieser Unkrautgesellschaften sind lehmige bis leicht sandige, mineralreiche Kalkböden. Das Fumario-Euphorbion hat sein Optimum in sonnigen, warmen Lagen, wo gelegentlich Trockenheit herrscht. An tief gelegenen Hängen findet sich die Einheit besonders häufig, aber es gibt auch Varianten (Soncho-Veronicetum agrestis) auf etwas frischeren Böden und in etwas höheren Lagen (bis in die montane Stufe).
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. |
