Walls are secondary habitats for well-dispersed rock species, but rarely for specialists and endangered plants; they provide surprisingly nutrient-rich and moist habitats, in which many species of the large species pool of synanthropic and forest vegetation coexist side by side with widespread rock species. Our considerations could be developed into a model of wall vegetation, in which subsequent filters of dispersal and physiological tolerance lead to the selection of a characteristic species pool. To do this in an explicit and quantitative fashion, an extension of the relevé databank with geological and climatological GIS-layers is desirable.
