INVASIVE SPECIES IN THE MIDDLE PART OF THE WARTA VALLEY

Summary/Abstract: The analysis covers invasive species of plants in the middle part of the Warta Valley. The research was carried out using the transect method. 21 species of invasive plants have been identified, among which the most numerous were Conyza canadensis, Acer negundo, Bidens frondosa, Solidago canadensis and Elodea canadensis. Invasive species were found in 12 types of habitats, but mostly in marshy woods (Almo-Ulmion relationship) and in biotopes with ruderal vegetation (Sisymbrion officinalis relationship). Invasive plants were the most numerous in the transects in the vicinity of Uniejów. Analysis of the research findings indicates that the flora of the examined part of the Warta valley has been changed to a moderate degree by invasion of non-native plant species.
