Thracian white oak-oriental hornbeam woods

[Quercus pubescens]-[Quercus virgiliana] woods of the Black Sea plains and hills of Turkey in Europe, and of the northern Thracian plain of southern and southeastern Bulgaria, where they are represented by mostly insular patches, particularly in the middle Maritsa and Tundja hills, the eastern and northern Rhodope foothills. The oaks are accompanied by [Carpinus orientalis], [Fraxinus ornus], [Acer campestre] or [Tilia tomentosa] and by Mediterranean floral elements.
