The intensification of agriculture has led to a distinct regress of segetal weeds, particu larly of the specialized ones. The necessity to preserve a gene pool of th is group of the species results from scientific and didactic premises as well as from practical ones. The author suggests to form a network of reserves for segetal communities on the fields of agriculture experimental stations, in the protective zones of national parks and reserves, in nature parks, and finally, in open-air museums.
