Abstract
The description of the landscapes, vegetation and flora of the site “Tonel River Mouth” located in the west of the protected zone of the Putorana Reserve, is given. Botanical-geographical studies of its territory were not conducted previously. The landscapes of the territory are atypical for the northwest of the Putorana Plateau – the mountains are relatively low; there is a wide terraced river valley; the boundaries of vegetation belts are blurred; in the tundra belt, meadow tundras are common and depressed trees are often present; belt of cold mountain deserts is missing; in the valley, large-bumpy (frost mound) peatlands occur, which are not characteristic of Putorana. Specific features of vegetation – the absence of forests with one-species tree stands, rich meadows on the mountain slopes, tall park grass birch forests, high-grass willow thickets in the valley and at the lake shores, communities of hydrophytes in shallow waters. The vascular plant flora includes 426 species and subspecies of 163 genera from 59 families, among them there are the species new to Putorana and Taimyr region as a whole. Based on the predominance of boreal species in the composition of the flora and higher participation of Eurasian species compared to Asian ones, it is possible to attribute the flora of the site to the Eurasian boreal type. The electronic appendix contains a complete annotated list.
