Abstract

In the city of Basel (Switzerland) Senecio inaequidens and five other neophytes
(Ambrosia artemisiifolia, Berteroa incana, Cynodon dactylon, Helianthus
tuberosus s.l. and Juncus tenuis) were mapped onto 61 500 m  500 m quadrats. At
each locality frequency, biotope and soil quality were recorded. In Basel S. inaequidens
is moderately spread and sparse. Since its first occurrence on railway areas in
the early eighties of the last century S. inaequidens has started to colonise the city,
many individuals or low density stands were observed in this study occuring across
the city. In Basel S. inaequidens grows mainly on open soils with humus rich soil or
coarse gravel. A. artemisiifolia, B. incana, C. dactylon, H. tuberosus s.l. and J. tenuis
are in Basel sparsely spread and sparse in number. For each species information on
the history of its colonisation, their current distribution, frequency, and its ecology
in Basel are shown and discussed.
