This association includes open, low-growing woodlands dominated by Quercus pubescens agg. or Q. petraea agg. in central and northern Bohemia. In contrast to the next association, some easterly distributed species are missing and mesic forest species are more common. These forests occur on south-facing slopes over limestone in the Bohemian Karst and on basalt hills in the České středohoří, rarely also on calcareous Cretaceous sediments and base-rich metamorphic rocks in the hilly landscapes along the Labe river.
