Abstract

Forest typological and ecological properties of natural complexes of the Emerald Network object of Ukraine “Tsyrkunivskyi forest” (UA0000290 Tsyrkunivskyi forest) in the Kharkiv region, with a total area of 9948.6 hectares are presented. This object is located in Lipetsk and Southern forest division of the State Forest Enterprise “Kharkiv Forest Research Station” in the north-western part of the Kharkiv region. The territory of the studied object is an undulating plain with a well-represented valley-beam relief and a fairly branched ravine-beam network. Forest areas are represented by stands of 35 tree species. The main forest-forming tree species is Quercus robur (8830.3 ha, 88.75%), a much smaller area is Pinus sylvestris (392.1 ha, 3.94%). Other tree species occupy small areas: Betula pendula (119.9 ha, 1.21%), Robinia pseudoacacia (88.5 ha, 0.89%), Acer platanoides (80.7 ha, 0.81%), Acer campestre (80.3 ha, 0.81%), Tilia cordata (75.4 ha, 0.76%), Populus tremula (66.4 ha, 0.67%), Fraxinus excelsior (52.4 ha, 0, 53%) and others. The studied forest areas are represented by 13 edatopes, covering all trophic groups and moisture levels. The most common types of forest vegetation conditions are fresh (7040.2 ha; 70.77%) and dry (2242.3 ha, 22.54%) oak dibrova. 19 types of forests were identified in the study area, the most common of which are fresh maple-linden dibrova (7040.2 ha, 70.78%), a slightly smaller area is dry maple-linden dibrova (2242.3 ha, 22.54%); much smaller is fresh oak-pine subir (354.1 ha, 3.56%). Quercus robur grows in 5 forest types, the most common of which are fresh (6552.8 ha, 74.21%) and dry (2102.0 ha, 23.80%) maple-linden dibrova
