The communities were analysed based on 64 phytosociological relev¨¦s made at 45 localities. 4 associations were found in the study area, that is, Digitarietum ischaemi, Echinochloo-Setarietum, Galinsogo-Setarietum, and Lamio-Veronicetum politae. Phytocenoses representing the associations Digitarietum ischaemi and Echinochloo-Setarietum were most varied floristically. Lower syntaxonomical units were determined within these associations, that is, subassociations and variants. These phytocenoses were frequently found; they occurred in various habitats characterized by different trophic and moisture conditions. Patches of the association Lamio-Veronicetum polita were rare and they occurred only on fertile soils and on small areas. %K root crops %K weed communities %K biodiversity of weeds %K Mazowiecki Landscape Park %U http://pbsociety.org.pl/journals/index.php/aa/article/view/1489
