Structure. Habitat is formed by low-growing dense deciduous shrubs with a considerable participation of xerothermophilic species, especially in the herb layer. Communities are characterized by the rich floristic composition. It is specified by the absence of thick shading by the canopy (small leaved shrubs prevail here) and penetration of the species from adjacent xerothermophilic herb and tree communities, which usually form mosaic complexes with the habitat. The sward height is about 30-60 cm with a total cover of 80-100% and is characterized by the three-layered structure. Shrub layer is 2 m high. Species of the edge of forest (

Geranium sanguineum ,
Teucrium chamaedrys ,
Veronica chamaedrys ,
Vincetoxicum hirundinaria
тощо) form the base of the sward.

Ecological characteristic. The habitat is usually represented by the small insular areas among the steppe vegetation. These are xerothermophilic and meso- xerothermophilic secondary (semi-natural) shrub communities. They are sporadically distributed on the well-drained dry loessial slopes of the west or south aspects with thin carbonate soils (rendzyny) and high humus content.

Threats. Reclamation of areas for agricultural crops, eutrophication, uncontrolled burning out, expansion of the invasive species (
Robinia pseudoacacia
L.) and overgrowing.

Management. Maintenance of the traditional management methods, thinning.
