Description	Walls are often considered secondary habitats for vegetation of natural rock surfaces. Compared with rocks, walls differ in many features, for example the presence of a binding material (mainly calcareous mortar), location in settlements and exposure to human impact. A data set of 1,205 phytosociological relevés recorded on horizontal wall tops, wall verticals and rock verticals in the Czech Republic was used to compare their vegetation with regard to i) species composition (frequent species, species diversity, endangered and alien species) and ii) the ecological requirements of the respective species. Gamma diversity of vascular plant species was comparable in all habitat types (242 species on wall tops, 212 species on wall verticals and 197 species on rock verticals). Wall verticals had higher beta diversity, but lower alpha diversity than rocks. Remarkable differences were found comparing the diversity of alien species.
