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 wellrepresented 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.
