The basis for in-depth studies of the southwestern district of the city of Abakan vegetation, the Republic of Khakassia was the lack of information on the current status, structure and species composition of the whole city flora.

The study of the flora was held by the honored worker of the Russian Federation Krasnoborov I. M. while working at the Herbarium of Khakass state university (KhSU) and Associate Professor of KhSU T. M. Zorkina. Flora of the South-Western area was identified based on field research expedition model area (MA) within the administrative boundaries of the city of Abakan in 2017-2018, the study of literature data and herbarium materials of the Krasnoyarsk state pedagogical University (KSPU) and Khakass state university (KhSU). Most of the territory of MA have been visited repeatedly and at different times of the growing season, and that suggests the method of urbanized landscape model areas.
