Our tests were carried out in Kunpeszér, in the territory of the Kiskunság National Park. The coenological recordings were made in 2x2 meter quadrates. We found out the species’ composition and coverage. In the test area mostly Achilleo-Festucetum pseudovinae (grass saline desert) grassland was located. The grassland vegetation flora was degraded by anthropogenic effects (trampling, grazing). The following weeds spread: ragweed (Ambrosia artemisiifolia);
canadian horseweed (Conyza canadensis); poppy (Papaver rhoeas); white goosefoot (Chenopodium album); hairy pigweed (Amaranthus retroflexus) and prickly plants: spiny restharrow (Ononis spinosa), and field thistle (Eryngium campestre).
