Abstract

The paper reports on finds of the invasive species Senecio inaequidens along motorways in Poland and Slovakia. The species was already mentioned in the floras of both countries but until recently there had been no reports from motorways there. In 2015, a large population of Senecio inaequidens was found along the A4 motorway in Poland. In 2013, it was collected along the D2 motorway in Slovakia. Intensive road traffic is probably the main vector of Senecio inaequidens invasion along motorways in Central Europe. Motor vehicles can carry the propagules over long distances. The newly recorded sites along the A4 in Poland and the D2 in Slovakia are part of the species’ invasion eastwards. It is assumed that Senecio inaequidens will continue to spread along motorways in both countries and in the region as a whole.

Abstract

The paper presents a new record of Dittrichia graveolens in Poland. This alien species was found growing on roadside verges in Głogoczów, West-Beskidian Piedmont, southern Poland, in 2016. An updated map of distribution of D. graveolens is provided based on the ATPOL cartogram method, and its pathway of spread along the roads is highlighted. Moreover, the Polish vernacular names “omanowiec” and “omanowiec wonny” are proposed for the genus Dittrichia and the species D. graveolens, respectively.
