Abstract: The study investigated the influence of soil properties and of time after completion of the revitalization on revitalized and non-revitalized sections of 16 rivers in Switzerland with regard to the presence of invasive neophytes. On nutritious topsoil neophytes covered on average 5.9 % of the areas examined, and on raw soil they covered 1.3 % (n = 1214 sub-transects). In recently revitalized river sections the average number of invasive neophyte species and the proportion of colonized plots were greater than in areas which had been revitalized six or more years before or along non-revitalized sections. The 16 studied rivers differed greatly regarding the occurrence and abundance of the neophyte species. Half of the stands of the in total most commonly found late blooming goldenrod (Solidago gigantea) were located along the rivers Thur and the Töss in the canton of Zurich. Results of the study showed that disturbances caused by revitalization together with nutritious soils particularly favour neophytes. Additionally clear differences between the 16 rivers indicate that the occurrence of invasive neophytes most likely also depends on existing populations in the neighbourhood.
