Invasion of species from genus Reynoutra in the Oświęcim Valley and its surroundings
Summary.

Species of Asiatic origin from Reynoutria genus belong to the most invasive and the most harmful plants for native species in Poland. The aim of the present study was to examine differences in distribution and abundance of population of R. japonica and R. sachalinensis in
6 towns situated in the Oświęcim Valley and its neighbourhood: Andrychów, Bielsko-Biała, Oświęcim, Pszczyna, Skoczów and Tychy. In the stand of a given species the following information, among others, was collected: type of habitat, area size, number of ramets, mean height of clump, mean diameter of ramets, and percentage cover of accompanying species. In total 269 stands including only 4 stands of R. sachalinensis were found. The highest number of populations was recorded in Pszczyna – 104 and the lowest – in Oświęcim – 21. More than 50% of all stands of knotweeds are ruderal habitats in such towns as: Bielsko-Biała, Tychy and Pszczyna. The studies demonstrated that differences in land use and spatial structure of towns affect distribution, invasiveness and traits of populations of focal species.

 

Key words: Reynoutria japonica, neophytes, biological invasions, urban ecology
