Arable lands occupy about 30 percent of the area of
the Załęcze Nature Park. Segetal weed associations in cereal plantations and in root crops were studied, and there were distinguished
6 associations, 3 communities, and several phytosociological units
of lower rank. From geographical and ecological points of view, the
presence of Arnoserido-Scleranthetum and Lamio-Veronicetum politae
is of great significance here. Among species of weeds rare in this
part of Poland are: Sherardia arvensis, Stachys annua, Bromus secalinus
and others (for summary see page 565-566).
