Floristic diversity of the intrazonal ecosystem of the Tovuzchay basin subalpine belt

The preservation of the biodiversity of mountain ecosystems is one of the independent problems of mountain regions. The formation and development of vegetation in the subalpine belt is largely determined by the ecological conditions of their habitat. Strongly sparse groups of cold-resistant plants, represented by hyperkryophytes and hemicryophytes: perennials of short stature, pillows, mosses and lichens, adapted to various habitats, are of predominant importance. The flora of the studied meadow communities is distributed according to the main taxonomic groups as follows: lichens 25%, spore 2%, conifers 13%, flowering 58%. Of the higher vascular plants, 45 species grow here, all flowering plants are combined into 20 families and 38 genera. In terms of life expectancy, all species are perennials, the main part of which, in terms of the rhythm of development, belongs to summer-green species. The article describes the flora of the subalpine belt of the Tovuzchay basin.
