Flora of the Kharbey Lakes (the East of Bolshezemelskaya Tundra)

Abstract

The paper contains the data on composition and structure of the Kharbey Lakes’ flora (the east of Bolshezemelskaya tundra) and its specific features. Flora of the Kharbey Lakes includes 91 species. Among them, there are 65 species of vascular plants, 25 species of bryophytes, and 1 species of charophytes. Potamogeton subretusus, which is a rare species for the European North-East of Russia, was found in shallow places of the Bolshoi Kharbey Lake. The Poaceae, Potamogetonaceae, Cyperaceae and Ranunculaceae families among vascular plants and Calliergonaceae, Sphagnaceae and Mniaceae among bryophytes have the greatest number of species. In the hydroecological aspect, vascular plants and bryophytes are dominated by hygrophytes. From the trophoecological point of view, flora usually includes mesotrophic groups of plants. By its geographical structure, the Kharbey Lakes’ flora corresponds with its zonal position as vascular plants are dominated by representatives of the Arctic-temperate latitude group and bryophytic plants are dominated by the boreal group with some hypo-arctic species
