Alliance LCC
Quercion petraeae Issler 1931

This alliance includes thermophilous oak forests growing on acidic to slightly calcareous soils in moderately warm and dry areas. Usually, Quercus petraea agg. is the dominant species. In places, Q. robur can dominate as well, whereas Q. pubescens agg. is nearly absent. Central European species as well as species of mesic forests are more common than in the other types of thermophilous oak forests. The range of this alliance is mainly central European, but it also occurs in continental eastern Europe.
