"QUERCUS ROBUR: FROM FOREST TO OAKSCAPE"
In Central Europe oaks have long been associated with typical forest habitats. This view is reflected in silviculture and traditional forest ecology. For the former oaks, after pine and spruce, and together with beech, are considered major target, while for the latter oak-lime-hornbeam old-growth is the epic characteristic of a "natural/virgin" forest. Both perspectives face a much poorer oak regeneration rate than one would expect as securing the durability of the Quercus share in European canopy stands.
The conondrum's explanation arises from the meta-analysis of the wide scope of the topical literature and from the current research, which is the ill-identification of the oak's regeneration niche. Although the
wide-scope evidence shows that Q. robur and Q. petraea colonize a wide range of open or semi-open habitats, most of the oak studies in Central Europe have been concentrated on forests. We suggest that the landscape mosaic of the sub-Carpathian silvopastoral landscape, extending from Transylvania to Przemyskie foothills, represent the true oak regeneration niche in Central-Southeastern Europe.
The goal of our project "Oak woods in rural landscape of the Carpathian region: origin, dynamics and conservation values" is defining diversity of silvopastoral oak woods in the Carpathian region with particular interest in their thermophilous character, and determining conditions and factors responsible for retaining thermophilous oak woods in the studied area.
