Vegetation of the Czech Republic
Senecioni sylvatici-Galeopsietum ladani Eliáš 1993
This vegetation type, dominated by Galeopsis ladanum, grows on both anthropogenic and natural screes consisting of various sedimentary, metamorphic and volcanic rocks with acidic to neutral reaction. Often the screes are mixed with fine soil, which can occasionally be more compacted than in the case of the association Galeopsietum angustifoliae. The dominant species is accompanied by calcifuge species of ruderal habitats, dry grasslands and forests. This association occurs in different areas of the colline and submontane belt of the Bohemian Massif, being more common in western Bohemia; however, it is poorly documented by relevés.
