During the study of waterlogged tundra soils of the Pleistocene Park Nature Reserve using light and scanning electron microscopy, 133 species of Bacillariophyta from 36 genera, 25 families, 14 orders and 3 classes were identified. Of these, 13 species are new to the flora of the Kolyma River basin, 10 are new to the flora of Russia, and 7 taxa are identified only to the genus. The most taxonomically rich genera are Gomphonema (25 species), Eunotia (16), Pinnularia (10), Encyonema (8), Cymbella (7), and Nitzschia (7). The species composition of the studied samples was more similar to that of aquatic ecosystems of the Kolyma River basin and nearby lakes (95 common taxa), which is apparently due to periodic flooding of the studied soils.
