Materials for the flora of the upper reaches of the Kondurcha river catchment basin (Samara region)

The proposed materials for the flora include indications of specific points of origin of all the mentioned species. This information can be useful when making notes of the flora of territories that are more extensive in area (Samara region), as well as solving other problems related to the study of the geographical distribution of species. For a number of years (2007-2017), the author examined the northern part of the Soksky physical-geographical region, located in the forest-steppe province of the High Trans-Volga region. Administratively, this territory belongs to the north-eastern part of the Samara Region. The study of flora was carried out in 15 geographic points, which are within 700 km2. At each point, the studies were carried out using the route method, taking into account the maximum coverage of the available ecotopes to maximize the identification of the species composition. Taking into account the data of V.V. Solovieva, who studied the flora of the Kondurcha reservoir located here, the designated area contains 624 species of vascular plants, of which 84 are alien and 540 are aboriginal. 42 species are among the rare ones included in the Red Data Book of Samara Region.
