Characteristics of geographical structure of the flora from the Urykta river basin (Eastern Baikal region)

An analysis is made of the geographical structure of the local flora within the Urykta river basin. Within its confines, we examine the partial flora of the hydrothermal “Zolotoi Klyuch” ecosystem. It is established that the local flora is an allochtonous, typically silvan (partly montane), rather weakly disturbed one; the composition reflects its geographical location in Southern Siberia, and the balance of longitudinal (eastward and westward) connections. The flora of the geothermal system is characterized as an intrazonal one, with a higher level of synanthropization, and with clearly defined features of steppization tending to gravitate in composition towards the Eastern-Asian floras.
