FLORA OF A SPECIALLY PROTECTED NATURAL AREA “FESCUE-FEATHER VIRGIN STEPPE ZONE”: CURRENT STATE AND ANTHROPOGENIC TRANSFORMATION
Abstract
The specially protected natural area “Fescue-feather virgin steppe zone” is located in the south of the Samara region in the subzone of the fescue-feather grass steppes of the Volga-Ural steppe region. This is one of the largest areas of the preserved steppes of the region, with a total area of 931.95 hectares. During the study period of the territory in 2018—2020, a summary of the flora was compiled, including 253 species of vascular plants belonging to 161 genera and 48 families. The territory of the natural monument is actively used as a grazing land, spring fires are carried out here, so our research naturally shows the presence of an adventitious component of the flora. The number of adventitious species does not exceed 9.5%, which indicates a low degree of anthropogenic transformation of the territory. The predominance of stepants (28%), as well as rare representatives, demonstrates the high preservation of the native “core” of the flora. The paper provides an annotated list that includes 24 plant species listed in the regional Red Book (2017). The largest populations are of the following species: Astragalus macropus, Ephedra distachya, Glycyrrhiza glabra, Lepidium coronopifolium, Palimbia turgaica, Plantago maxima and Valeriana tuberosa. Such species as Eriosynaphe longifolia, Iris pumila, Tulipa schrenkii are protected at the state level.
