Poland is a country, in which biological diversity has been well retained. This concerns both arable fields and areas economically exploited in other ways. This results both from the small size of most farms, relatively extensive and traditional farming techniques, and low-scale chemicalization of agriculture. The species biological diversity of segetal weeds is manifest in the existence of 404 species composing 207 genera and 49 families in Poland. The threat posed to the segetal flora is quite severe because it concerns 100 species, which is about 25% of its whole number.

In this paper a preliminary list and characterization of the synanthropic flora found in the area of the Łęczyca in 1998-2000, have been presented. The rich variety of the synanthropic flora of this town is an effect of differentiation of habitats and man’s economic activity. The synanthropic flora of Łęczyca consists of 551 taxons. Among synanthropic plants predominate perenial plants (56,8%) and apophytes (59,9%). There ars 31 species from the list of threatened synanthropic plants and 8 species from the list of protected plants.
