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.

Floristic research on segetal communities was carried out in 2000 on arable fields in the Skierbieszów Landscape Park and its protected zone. Three communities of segetal weeds in cereal crops, and two communities of segetal weeds in root crops were separated in the arable fields of the Skierbieszów Landscape Park. The community <i>Vicietum tetraspermae typicum</i> commonly occurred in cereal crops on brown soils developed from loess soils. The community <i>Echinochloo-Setarietum</i>, which belongs to root crops, was noted in the same habitat. The greatest richness of species was found in <i>Consolido-Brometum</i> and <i>Lamio Veronicetum politae</i>, with the average of 25 species in one record. Both communities were abundant in rare segetal species which are considered to be endangered in our country: <i>Adonis aestivalis</i>, <i>Euphorbia exigua</i>, <i>Lathyrus tuberosus</i>, <i>Muscari comosum</i>, <i>Thlaspi perfoliatum</i>, <i>Veronica polita</i>, <i>Agrostemma githago</i>.

Characteristics of the changes in the agrophytocoenoses of the Bełchatów Industrial Region are presented in this paper. The observations were conducted on permanent areas during 1977-1983. Biological (phytosociological and bioindicatorial) methods were used. The dynamics of changes in weed communities in crop rotation were anlysed. Changes in the composition and structure of agrophytocoenoses belonging to 10 syntaxonomes and changes in their habitats were found. The causes and directions of these changes were established. These processes lead to the impoverishment of segetal flora and the formation of simpler formations which are less stable and less resistant to anthropopressure. On the basis of the results obtained in this study, an evaluation of the productivity of field habitats was made, agroecological regions were discerned and ways of forming and protecting agricultural production areas of the Bełchatów Industrial Region are given.

Smal part (1100 ha - 4,7 %) of the Landscape Park Pojezierze Iławskie is an agricultural area. On the arable soils of this area floristic and phytosociological studies of weed communities were performed. In total, 156 species of vascular plants were registered what makes 75 percent of the whole segetal population high diferentitation in field plants was found. Seven associations and three communities of segetal plants were distinguished. High quantitative participation of the field plant communities in the range of associations (72 percent studied areas) allows us to suggest that the degree of agrocenosis degradation is very small in this area as compare to the majority of the agricultural areas in Poland. Taking into account floristical and ecological diferentiation, geographical range and syntaksonomical position three assiociations (<i>Teesdaleo-Arnoseridetum minimae, Aphano-Matricarietum</i> and <i>Spergulo-Chrysanthemetum segeti</i>) present high specific value and deserve of the active form of protection.

The aim of the study was to characterize and analyze the segetal flora of the Łuków Plain. The study was carried out from 2003 to 2006 in 182 towns and villages. Vascular flora of the arable fields in the area under study consists of 305 species belonging to 39 families and 168 genera. The analysed flora is characterised by the prevalence of native species (64.6%) over alien species (35.4%). Archaeophytes dominate among anthropophytes, whereas meadow species are the most frequent in the group of apophytes. Annuals and biennials show a slight prevalence over perennials. The analysis of the life-form categories shows the dominance of therophytes (52.8%) as well as a relatively high share of hemicryptophytes (34.4%) and geophytes (12.5%). In the analysed flora, rare and very rare species constitute a vast majority (61.7%), whereas the common and very common species reach 13.1%.

<p>A study of fallow lands in the Podlaski Przełom Bugu (Podlasie Bug River Gorge) mesoregion was conducted over the period 2001–2004 in 77 villages belonging to 20 municipalities located in the Bug River valley along the stretch of the river from Terespol to Małkinia Górna. The aim of this study was to carry out a survey of vascular plants in fallow lands and to perform their multifaceted analysis. The study investigated quantitative and qualitative changes taking place in fallow vegetation with the passage of time from the abandonment of purposeful cultivation. Plant patches in 1–2-year, 3–6-year, 7–10-year and more than 10-year fallows were studied. Vascular plants of fallow lands within the study area comprise 442 species. 3–6-year fallows were richest in species (355). With increasing fallow age, the number of species decreased to 205 species in fallows older than 10 years. Hemicryptophytes dominated in plant communities of fallow lands. Therophytes were the co-dominant biological type in the youngest fallows. Chamaephytes and geophytes in all fellow age groups accounted for about 5%. Among vascular plants of fallow lands, native species dominated and their percentage increased with increasing fallow age, while at the same time the proportion of archeophytes decreased. With the increasing age of fallows, the proportion of species characteristic of forest communities also increased, whereas the percentage of segetal species simultaneously decreased. With the passage of time from the abandonment of cultivation, one can observe the evolution of plant cover of fallow fields from segetal communities towards less synanthropic communities.</p>

Field studies were carried out using the Braun-Blanquet method (1964) in the years 1995-1999, in 42 localities situated within the protective zone of Roztocze National Park (RNP). Phytoindication photos of cereal crops were taken twice: in spring (spring aspect) and in the first half of July. Photos of root crops were taken only once, at the beginning of September. Segetal flora of the RNP protective zone includes 233 species of vascular plants belonging to 36 botanical families. The most aboundant families are: Asteraceae (23 species), Fabaceae (23 species), Poaceae (21 species), Brassicaceae (16 species), Caryophyllaceae (16 species). In segetal flora of the protective zone, apophytes (57%) out numbered antropophyta. Among apophytes, the largest group consisted of meadots apophytes (30%). In the antropophyta group archeophytes dominated (34%) over epecophytes (6%) and ergasiophygophytes (3%). In segetal flora there was a greater number of annual and biennial species (150 species) than perennial species (83 species).
