| Summary: | Summary. In 2017, a field research of the aquatic macrophyte flora of 29 water bodies in Kurgan region was carried out. Samples of aquatic macrophytes were collected, geobotanical descriptions of plant aggregations were made, and water samples for chemical analysis were taken from the ecotopes. For the preparation of the next edition of the Red Data Book of Kurgan region, the found populations of rare aquatic macrophytes such as Ruppia maritimа L., Chara aspera Deth. ex Willd., Chara contraria A. Br., Chara kirghisorum Lessing emend. Hollerb. are of interest. Newdata on the locations, coenotic environment, and ecology of these species in Kurgan region are provided; also, the rare species Chara aspera, C. contraria, C. kirghisorum at the northern bound of their area are recommended for inclusion in the next edition of the regional Red Data Book. Работа выполнена при поддержке РФФИ и Правительства Ханты-Мансийского автономного округа – Югры в рамках научного проекта р_урал_а № 15-44-00014.
