Die synanthrope Vegetation der Stadt Wolfenbüttel

Brandes, Dietmar GND

The synanthropic Vegetation of the town Wolfenb├╝ttel (Lower Sayony) is relatively manifold with about 35 plant communities (23 associations). The distribution of the ruderal plant communities within the indi-vidual quarters expectingly is not equal, the pattern is like in Brunswick. City and new, dense settled quarters show only a few ruderal communities poor in species and often fragmentarily developed. Only on rebuilding areas short living Fumario-Euphorbion-communities are to be found. Thermophilous plant communities accumulate on railway stations, on ruins, and on rubble at the out-skirts. On fallow areas and former tracks develop long living communities dominated by grasses or associations belonging to the alliance Dauco-Melilotion. Nitrophilous skirt communities develop very well in the "Wallgebiet" and in the "Lechlumer Holz", a forest belonging to the urban area. Typical rural Vegetation is yet to be found in a few villages, belonging to the urban area, it is threatened by increasing urbanisation. The environment of a beet loading place is marked by very nitrophilous communities. Some of these associations show a clear subcontinental spreading. The occurrence of Atriplex rosea, Ficus carica and Rapistrum rugosum shows the floristic particularity of the investigated area.
