Assessment of the floristic composition of sward grazed by various animal species
The study objective was to assess the floristic composition of pastures for wild animals (fallow deer, Manchurian deer and mouflons) at Przytoczno, pastures for horses at Białka, and cow pastures belonging to the Land Community in Tarnogóra. We analyzed the floristic composition of the pastures under study in the growing seasons of 2011 and 2012, carried out 32 phytosociological relevés in the wild animal pastures, 32 in the horse pastures, and 38 in the cow pastures, using the Braun-Blanquet method. We determined the species diversity of the pastures based on the percentage share of species from the botanical families distinguished, the total number of species, and the Shannon–Wiener and Simpson diversity index. Our floristic surveys indicated that the greatest species diversity occurred in the horse pastures, while it was lower in the wild animal and cow pastures. The Shannon–Wiener diversity index for the sward of the pastures grazed by horses was higher (H' = 5.04) than for those grazed by wild animals (H' = 4.32) and cows (H' = 3.53). The Simpson index of species diversity in a community was higher for the pastures grazed by horses (S = 0.96) than for those grazed by wild animals (S = 0.95) and cows (S = 0.90)

Flora in abandoned fields and adjacent crop fields on rendzina soils in the Zamość region
A floristic inventory of segetal flora was carried out in abandoned fields and adjacent crop fields on rendzina soils in the Zamość region in the year 2010. This study found a total of 130 weed species belonging to 30 botanical families. The following families were represented most frequently: Asteraceae, Fabaceae, Poaceae, Lamiaceae, Scrophulariaceae, and Brassicaceae. In the segetal flora, apophytes are dominant (55% of the total flora), with the highest number of meadow and xerothermic grassland species among them. Archeophytes (38%) predominate in the group of anthropophytes. The species characterized by the highest constancy classes and reaching the highest cover indices posed the greatest threat to crops in the study area. The following weeds are most frequently found in fallow fields: Consolida regalis, Cichorium intybus, and Sinapis arvensis, while Papaver rhoeas is the greatest threat to cereal crops grown on rendzina soils
Floristic diversity and agricultural value of Phalaridetum arundinaceae (Koch 1926 n.n.) Lib. 1931 in the selected river valleys of the Zamość region
The study presents the results of a floristic survey conducted using the Braun-Blanquet method (50 phytosociological relevés) in permanent grasslands in three river valleys of the Zamość region (Por, Huczwa, Wieprz). The goal of the survey was to determine the floristic diversity and fodder value of the Phalaridetum arundinaceae association (Koch 1926 n.n.) Lib. 1931.
A total of 93 plant species from 25 botanical families were identified in the areas under study. The species richness of the Phalaridetum arundinaceae differed among river valleys. It was observed that these are often transitional forms similar to the association of the Molinio-Arrhenatheretea class, Molinietalia order. Predominance of hemicryptophytes and a relatively large share of geophytes was recorded. Based on the fodder value score calculated for the dry matter of the association, the community under study can be classified as having a medium or poor nutritional value
