Background. The article provides an analysis of the population analysis of the shrub synusia of the “Kuncherovskaya lesostep” – one of the five sites of the State Nature Reserve “Privolzhskaya lesostep”. Materials and methods. The study of shrub synusia was carried out for 3 years. Complete geobotanical descriptions were carried out to reveal the floristic composition. The study of the state of populations was carried out by generally accepted population methods. Results and conclusions. The population structure of 9 shrubs was analyzed, as well as Acer tataricum L., which forms a “bushlike” form of growth under the conditions of the Kuncherovskaya forest-steppe. their confinement to relief elements is noted. Of the 10 analyzed species of woody plants, only 3 populations are full-membered normal - in Euonymus verrucosa, Acer tataricum and Frangula alnus. The age spectra of Rhamnus cathartica, Corylus avellana, Chamaecytisus ruthenicus, and Rubus idaeus populations are incomplete and fragmented. The populations of Cerasus fruticosa and Lonicera xylosteum are incomplete, regressive. The most numerous population is the spindle tree.
