Contributions to the wall flora of Albania Dietmar Brandes http: //www.ruderal-vegetation.de/verschiedene_regionen/Albania.pdf Wall flora of southwest Albania The ruderal vegetation of Albania was studied in May • 2010. In old towns like Berat and Gjirokastër we found some • 100 species growing in walls. Parietaria judaica is the most common species like in • other countries of southern Europe. Besides species of the class Asplenietea we found some • common weeds and ruderals in walls. Old walls are sometimes colonised by seedlings of • neighbouring trees like Celtis australis, Pistacia lentiscus Platanus orientalis or Quercus coccifera. The wall flora is endangered outside historical • settlements because of the exclusive use of concrete construction.
