The forest typological analysis of forest stands was done based on the PO ‘Ukrderzhlisproekt’ Database, fund and cartographic documents and other materials of permanent forest management. Ten forest types were determined based on the data of the forest management. The most common forest type is dry birchbark-and-oak fertile site that occupies 75.5 % of the area. All the stands in the reserve were divided into 2 protection categories, namely the natural sanctuary – 552.9 ha (71.8 %) and the anti-erosion forests – 217.4 ha (28.2 %). Maturing, mature and overmature age groups make 62.3 % of the stands. The stands of 3rd and lower growing classes make 83.6 %. The stands of vegetative origin cover 38.7 %, those of seed man-made origin – 41.0 % of the area. As for a health condition, most of the stands are severely weakened. The reasons of the stands’ die-back are weakening due to severe climatic conditions of the Steppe and, on being weakened, trees become affected by root rot. The study found that the most resistant tree species is common oak.
