It consists of three clusters of core areas, which are surrounded by buffer zones and connected via a protected eco-corridor.

These forests are composed mainly of pine (Pinus sylvestris), birch (Betula pendula, B. pubescens) and aspen (Populus tremula).

In the shrub dominated parts, typical steppe shrubs are Russian almond (Amygdalus nana), cherry (Cerasus fruticosa), greenweed (Cytisus ruthenicus) (western distribution boundary), species of wild roses (Rosa) and juniper (Juniperus sabinea).

Typical mammals of the steppe zone are steppe polecat (Mustela eversmanni), corsac fox (Vulpes corsac), common fox (Vulpes vulpes), Eurasian wolf (Canis lupus lupus), long-eared hedgehog (Erinaceus auritus), European hare (Lepus europaeus) and several rodent species like bobak marmot (Marmota bobac), large-toothed souslik (Spermophylus fulvus), red-cheeked souslik (Spermophylus major), little souslik (Spermophylus pygmeus), common hamster (Cricetus cricetus), jerboas (Allactaga major, Stylodipus telum) as well as several species of voles and lemmings.
