Hydromacrophytes composition in water reservoirs of the North-Eastern part of the Kurgan Region

Hydromacrophyte flora of 22 water bodies in the Kurgan Region was studied in 2017. The aquatic study was conducted within the 6 administrative districts of the Kurgan Region: Chastoozersky (4), Petrovsky (2) Makushinski (7), Lebyazhyevsky (4), Vargashinsky (2), and Mokrousovsky (3). The area of the research was between 55 09 minutes of the North latitude and 5548 of the North latitude, from West to East - between 6553 of the East latitude and 69 19 minutes of the East latitude. During the research we selected and recorded samples of macroalgae and collected herbarium of higher hydromacrophytes. The paper contains data on species composition and frequency of hydromacrophytes occurrence; new location of Ruppia maritima L. that is considered to be rare in the Kurgan Region was found. Its the first time the specific structure of mаcroscopic algae has been given for the territory of research. It is noted that the species of Chara contraria A. Br., is a rare one, and here it is located on the Northern border of its distribution, therefore it needs protection. Most of the identified species of hydromacrophytes are common in the West Siberian plain (Northern Kazakhstan, Tyumen Region). The paper also contains information about the location of invasive species Elodea canadensis Michx. The obtained materials can serve as a basis for further hydrobotanical study of water reservoirs in the Kurgan Region.
