Rare and endangered species of segetal flora in the Turobin commune

The aim of the study was to make an inventory and describe the localities of interesting species inhabiting the segetal communities of the Turobin commune, which are regarded as endangered in Poland and Europe. The paper presents results of a field study conducted in 2011-2013 in crop fields, located on brown soils and rendzinas. Phytosociological relevés were made with the Braun-Blanquet method at the sites of phytocoenoses comprising interesting and endangered species. The habitat was assessed with the use of soil-agricultural maps, and soil pH was measured at the site where the phytosociological relevés were taken. In the Turobin commune, 32 interesting species were found; some of them are considered rare and endangered in Poland. In this group, the occurrence of Asperugo procumbens, regarded as an endangered species and included in the red list of vascular plants, is noteworthy
