This association includes tall herbaceous stands dominated by Solidago canadensis or S. gigantea, invasive neophytes of North American origin, which can grow either in monodominant or mixed stands. They rapidly colonize newly disturbed sites through wind dispersal and once established, spread extensively by means of rhizomes. These stands are found in river floodplains, on dumping sites, construction sites, in disturbed unmown grasslands in cities and villages, abandoned fields, among buildings in industrial zones or along railways. Soils may be moderately wet to dry, usually with a high content of sand or stones. This vegetation type is common in the lowland to submontane areas of the Czech Republic.
