This community is dominated by Sisymbrium loeselii. It colonizes bare substrata such as soil heaps around construction sites and strip mines, ballast deposits and places around railway stations. Soils are sandy to loamy and rich in nutrients. The Sisymbrietum loeselii is similar to the Descurainietum sophiae, but the latter is less thermophilous. Stands of the Sisymbrietum loeselii attain their maximum biomass from July to October. They are found in warm areas of the Czech Republic, particularly in the city suburbs.
