it is not native to Slovakia
Ecology
it is a light-loving tree with low requirements for nutrient content and soil moisture
heat-demanding, grows well hl. on limestones, in our country it is resistant to frost
in the places of its original occurrence - it creates homogeneous and mixed stands with Scots pine (Pinus sylvestris), Halep pine (Pinus halepensis), maritime pine (Pinus pinaster), white fir (Abies alba), Greek fir (Abies cephalonica), cerium oak (Quercus cerris), felt oak (Quercus pubescens), holly oak (Quercus ilex), ...
